Amplifiers

Texas Instruments (TI) offers a wide range of op amp types including high precision, microPower, low voltage, high voltage, high speed and rail-to-rail in several different process technologies. TI has developed the industry's largest selection of low-power and low-voltage op amps with features designed to satisfy a very wide range of applications. To help facilitate the selection process, an interactive online op amp parametric search engine is available at amplifier.ti.com/search with links to all op amp specifications.

Design Considerations

Choosing the best op amp for an application involves consideration of a variety of interrelated requirements. In doing so, designers must often consider conflicting size, cost and performance objectives. Even experienced engineers can find the task daunting, but it need not be so. Keeping in mind the following issues, the choices can quickly be narrowed to a manageable few.

Supply voltage (VS)—tables include low

voltage (< 2.7V min) and wide voltage range (> 5V min) sections. Other op amp selection criteria (e.g., precision) can be quickly examined in the supply range column for an appropriate choice. Applications operating from a single power supply may require rail-to-rail performance and consideration of precision-related parameters.

Precision—primarily associated with input

offset voltage (VOS) and its change with respect to temperature drift, PSRR and CMRR. It is generally used to describe op amps with low input offset voltage and low input offset voltage temperature drift. Precision op amps are required when amplifying tiny signals from thermocouples and other low-level sensors. High-gain or multi-stage circuits may require low offset voltage.

Gain bandwidth product (GBW)—the gain

bandwidth of a voltage-feedback op amp determines its useful bandwidth in an application. The maximum available bandwidth is approximately equal to the gain bandwidth divided by the closed-loop gain of the application. For voltage feedback amplifiers, GBW is a constant. Many applications benefit from choosing a much wider bandwidth/slew rate

op amp to achieve low distortion, excellent linearity, good gain accuracy, gain flatness or other behavior that is influenced by feedback factors.

Power (IQrequirements)—a significant issue

in many applications. Because op amps can have a considerable impact on the overall system power budget, quiescent current, especially in battery-powered applications, is a key design consideration.

Rail-to-rail performance—rail-to-rail

output provides maximum output voltage swing for widest dynamic range. This may be particularly important with low operating voltage where signal swings are limited. Rail-to-rail input capability is often required to achieve maximum signal swing in buffer (G = 1) single-supply applications. It can be useful in other applications, depending on amplifier gain and biasing considerations.

Voltage noise (VN)—amplifier-generated

noise may limit the ultimate dynamic range, accuracy or resolution of a system. Lownoise op amps can improve accuracy, even in slow DC measurements.

Input bias current (IB)—can create offset

error by reacting with source or feedback impedance. Applications with high source impedance or high impedance feedback elements (such as transimpedance amplifiers or integrators) often require low input bias

current. FET-Input and CMOS op amps generally provide very low input bias current.

Slew rate—the maximum rate of change of

the amplifier output. It is important when driving large signals to high frequency. The available large signal bandwidth of an op amp is determined by the slew rate SR/.707(2π)V

Package size—TI offers a wide variety of

microPackages, including WCSP, SOT23, SC70 and small, high power-dissipating PowerPAD™ packages to meet spacesensitive and high-output drive requirements. Many TI single-channel op amps are available in SOT23, with some dual amplifiers in SOT23-8.

Shutdown mode—an enable/disable

function that places the amp in a high impedance state, reducing quiescent current in many cases to less than 1µA. Allows designers to use wide bandwidth op amps in lower power applications, enabling them only when they are needed.

Decompensated amplifiers—for

applications with gain greater than unity gain (G > 1), decompensated amps provide significantly higher bandwidth, improved slew rate and lower distortion over their unity-gain stable counterparts on the same quiescent current or noise.

What is the amplitude of the input signal?

To ensure signal errors are small relative to the input signal, small input signals require high precision (e.g., low offset voltage) amplifiers. Ensure that the amplified output signal stays within the amplifier output voltage.

Will the ambient temperature vary?

Op amps are sensitive to temperature variations, so it is important to consider offset voltage drift over temperature.

Does the common-mode voltage vary?

Make sure the op amp is operated within its common-mode range and has an adequate common-mode rejection ratio

(CMRR). Common-mode voltage will induce additional offset voltage.

Does the power supply voltage vary?

Power supply variations affect the offset voltage. This may be especially important in battery-powered applications.

Precision Application Examples

• High gain circuits (G > 100)

• Measuring small input signals (e.g., from a thermocouple)

• Wide operating temperature range circuits (i.e., in automotive or industrial applications)

• Single-supply ≤ 5V data-acquisition systems where input voltage span is limited

Common Op Amp Design Questions

Texas Instruments 3Q 2007 Amplifier and Data Converter Selection Guide

Amplifiers

➔

Technology Primer

Understanding the relative advantages of basic semiconductor technologies will help in selecting the proper device for a specific application.

CMOS Amps—when low voltage and/or low

power consumption, excellent speed/power ratio, rail-to-rail performance, low cost and small packaging are primary design considerations, choose microPackaged CMOS amps boasting the highest precision in the industry.

High-Speed Bipolar Amps—when the highest

speed at the lowest power is required, bipolar technology delivers the best performance. Extremely good power gain gives very high output power and full power bandwidths on the lowest quiescent power. Higher voltage requirements are also only satisfied in bipolar technologies.

Precision Bipolar Amps—excel in limiting

errors relating to offset voltage. These amps include low offset voltage and temperature drift, high open-loop gain and common-mode rejection. Precision bipolar op amps are used extensively in applications where the source

impedance is low, such as a thermocouple amplifier, and where voltage errors, offset voltage and drift, are crucial to accuracy.

Low I

FET Amps—when input impedance is

very high, FET-input amps provide better overall precision than bipolar-input amps because of very low input bias current. Using a bipolar amp in applications with high source impedance (e.g., 500MΩ pH probe), the offset, drift and noise produced by bias currents flowing through the source would render the circuit virtually useless. When low current errors are required, FET amps provide extremely low input bias current, low offset current and high input impedance.

Dielectrically Isolated FET (Difet™) Amps—

Difet processing enables the design of extremely low input leakage amplifiers by eliminating the substrate junction diode present in junction isolated processes. This technique yields very high-precision, lownoise op amps. Difet processes also minimize parasitic capacitance and output transistor saturation effects, resulting in improved bandwidth and wider output swing.

Amplifiers

High-Speed Amplifiers

➔

TI develops high-speed signal conditioning products using state-of-the-art processes that give leading-edge performance. Used in high-speed signal chains and analog-to-digital drive circuits, high-speed amps are broadly defined as any amplifier having at least 50MHz of bandwidth and at least 100V/µs slew rate. High-speed amps from TI come in several different types and supply voltage options.

Design Considerations

Voltage-feedback type—the most

commonly used amp and the basic building block of most analog signal chains such as gain blocks, filtering, level shifting, buffering, etc. Most voltage-feedback amps are unitygain stable, though some are decompensated to provide wider bandwidth, faster slew rate and lower noise.

Current-feedback type—most commonly

seen in video or DSL line driver applications, or designs where extremely fast slew rate is needed.

Fully differential amplifier (FDA)—the fully

differential input and output topology has the primary benefit of reducing even order harmonics, thereby reducing total harmonic distortion. The FDA also rejects common-mode components in the signal and provides a larger output swing to the load relative to singleended amplifiers. Fully differential amplifiers are well-suited to driving analog-to-digital converters. A V

COM

pin sets the output common-mode voltage required by newer, single-supply, ADCs.

FET-Input (or CMOS) amplifiers—have higher

input impedance than typical bipolar amps and are more useful to interfacing to high impedance sources, such as photodiodes in transimpedance circuits.

Video amplifiers—can be used in a

number of different ways, but generally are in the signal path for amplifying, buffering, filtering or driving video lines. The specifications of most interest are differential gain and differential phase. Current-feedback amps are typically used in video applications, because of their combination of high slew rate and excellent output drive at low quiescent power.

Fixed and variable gain—these amps have

either a fixed gain, or a variable gain that can be set either digitally with a few control pins, or linearly with a control voltage. Fixed-gain amplifiers are fixed internally with gain setting resistors. Variable gain amplifiers can have different gain ranges, and can also be differential input and/or output.

Packaging—high-speed amplifiers typically

come in surface-mount packages, because parasitics of DIP packages can limit performance. Industry standard surface-mount packages (SOIC, MSOP, TSSOP and QFN) handle the highest speed requirements. For bandwidths approaching 1GHz and higher, the QFN package decreases inductance and capacitance.

Evaluation boards—high-speed amps have an

associated fully populated evaluation module (EVM) or an unpopulated printed circuit board (PCB). EVMs are a very important part of high-speed amplifier evaluation, since layout is critical to design success. To make layout simple, Gerber files for the EVMs are available. See page 101 for more information.

OPA3875 functional block diagram.

Key Features

• Small-signal bandwidth: 700MHz (AV=+2)

• Bandwidth: 425MHz, 4V

• Gain flatness: 0.1dB to 200MHz

• Channel switching time: 4ns

• Switching glitch: 40mV

• Slew rate: 3100V/µs

• Gain accuracy: 2.0V/V ±0.4%

• 0.025%/0.025° differential gain/phase

• Packaging: SO-8 or MSOP-8 (OPA875) or SSOP-16 (OPA3875)

Applications

• RGB or Y/Pb/Pr video switching

• Analog routing switcher

• LCD projector input select

• High resolution monitors

• Broadcast video processing

• Triple high speed ADC input mux

The OPA875 and OPA3875 are high-speed, very wideband, single-channel and triple-channel, 2:1 multiplexers. Gain accuracy and switching glitch of 40mV

are improved over earlier solutions using a new (patented) input stage switching approach. System power may be optimized using the enable feature for the OPA3875. Using this, the OPA3875 powers down to a mere 0.9mA total supply current. The fixed gain-of-2 output stage is ideal for driving double terminated video loads directly. Where a single channel of the OPA3875 is required, consider the OPA875.

rail-to-rail output that swings within 100mV of the rails to allow for either AC or DC-coupling. The THS7347 incorporates a 500MHz bandwidth, 1200V/µs unity-gain buffer making it ideal for driving ADCs and video decoders, where the THS7327 offers an integrated 5th order Butterworth anti-aliasing filter on each channel. These filters improve image quality by eliminating DAC images.

Portable Video— Successfully designing a

high-performance video system into low voltage portable applications requires careful attention to many details. Portable applications impose very challenging technical requirements beyond those required in typical video applications and demand particular trade-offs in performance, power consumption, printed circuit board space and cost. A DCcoupled solution with integrated gain, low-pass filter, level-shifter, and shutdown solves these challenges while maintaining good video performance and eliminates the need for large, expensive discrete components. The standard definition (SDTV) THS7314 and high definition (HDTV) THS7316 easily meet these trade-offs by maintaining outstanding low-cost performance while the EDTV/SDTV line driver THS7318, with it’s small profile wafer scale package, is ideal for extremely board space sensitive applications.

The new low power THS7315 is a fullyintegrated SDTV video amplifier which features a rail-to-rail output stage allowing for both AC and DC line driving. The low 15.6mA quiescent current at 3.3V makes it an excellent choice for USB powered or other power sensitive video applications.

Video amplifiers—can be used in a number

of different ways, but generally are in the signal path for amplifying, buffering, filtering or driving video lines. The specifications of most interest for composite video signals, or CVBS, are differential gain and differential phase. For other video signals, such as Y’P’bP’r or RGB, bandwidth – both small signal and large signal, and slew rate are of most importance. Noise and DC accuracy is also considered important in some high-end applications.

The traditional Voltage-Feedback (VFB) amplifiers are widely used because of their ability to be configured for almost any situation. Many VFB amplifiers have the ability to accept input signals going to the negative rail (or ground), allowing use in many single-supply systems. Additionally, many VFB amplifiers offer rail-torail outputs offering the widest dynamic range possible on small supplies. Traditional VFB amplifiers (non-RRO) designed for video offer the ability to have very high slew rates, wide bandwidths, low noise, and very good DC characteristics. Current-feedback amps are commonly found in high-end video applications, because of their combination of high slew rate and excellent output drive at low quiescent power.

High-Speed Video Multiplexers—

Numerous video applications, such as RGB or YPbPr video switching, video routers, high resolution monitors, etc. are creating an increased need for high-speed switching with multiplexers (muxes). With the increased need to reduce board space are also the demands that these muxes provide low power consumption as well as increased functionality, such as the ability to drive 75-Ohms or 150-Ohms while maintaining good video

performance specifications. These specifications include low crosstalk, fast settling, gain flatness, low switching glitch along with low differential gain and differential phase. The new OPA875 and OPA3875 singleand triple 2:1 multiplexers along with the new OPA4872, 4:1 multiplexer easily meets these requirements. Using a new patented input stage switching approach, the switching glitch is much improved over earlier solutions. This technique uses current steering as the input switch while maintaining an overall closedloop design.

TI brought new technology to the market with the introduction of the THS7303, THS7313 and THS7353. These three-channel devices were the first to offer full I2C programmability of all functions independently for each channel, which provides the designer the flexibility to configure a video system as required or on-thefly, without the need for hardware upgrades or modifications. The devices are designed with integrated Butterworth filters to provide all the analog signal conditioning required in video applications such as set-top boxes, digital televisions, personal video recorders/DVD readers and portable USB devices. These highly integrated devices provide space savings as a result of the high levels of integration and advanced package technology.

The strong combination of integrated features and optimized design make TI’s THS7327 and new THS7347, well suited for use in projectors and professional video systems. Both 3-channel RGBHV video buffers offer a monitor pass-thru amplifier, unity gain buffer, 2:1 input mux, I2C control of all functions on each channel, HV synch paths with Adjustable Schmitt Trigger, selectable bias modes and

Comparators

➔

Comparator ICs are specialized op amps designed to compare two input voltages and provide a logic state output. They can be considered one-bit analog-to-digital converters.

The TI comparator portfolio consists of a variety of products with various performance characteristics, including: fast ns response time, wide input voltage ranges, extremely low quiescent current consumption and op amp and comparator combination ICs.

Comparator vs. Op Amp

Comparator Op Amp

Speed (Response time) Yes No Logic Output Yes No Wide Diff. Input Range Yes Yes Low Offset Drift No Yes

In general, if a fast response time is required, use a comparator.

Design Considerations

Output topology

• Open collector—connects to the logic supply through a pull-up resistor and allows comparators to interface to a variety of logic families.

• Push-pull—does not require a pull-up resistor. Because the output swings rail-torail, the logic level is dependent on the voltage supplies of the comparator.

Response time (propagation delay)—

applications requiring “near real-time” signal response should consider comparators with nanosecond (ns) propagation delay. Note that as propagation delay decreases, supply current increases. Evaluate what mix of performance and power can be afforded. The TLV349x family offers a unique combination of speed/power with 5µs propagation delay on only 1µA of quiescent current.

Combination comparator and op amp—for

input signals requiring DC level shifting and/or

Difference Amplifiers

Common-mode input voltage range—

selection of the most suitable difference amp begins with an understanding of the input voltage range. Some offer resistor networks that divide down the input voltages, allowing operation with input signals that exceed the power supplies. A five-resistor version of the simple difference amplifier results in a device that can operate with very high levels of common-mode voltage—far beyond the supply rails.

Gain—signal amplification needed for the

desired circuit function must be considered. With the uncommitted on-chip op amp, the INA145 and the INA146 can be configured for gains of 0.1 to 1000.

Sensor impedance—should be <0.001 of

difference amp input impedance to retain CMR and gain accuracy. In other words, the amp input impedance should be 1,000 times higher than the source impedance.

Offset voltage drift (µV/°C)—input offset

voltage changes over temperature. This is more critical in applications with changing ambient temperature.

Quiescent current—often of high importance

in battery-powered applications, where amplifier power consumption can greatly influence battery life.

Slew rate—if the signal is reporting a

temperature, force or pressure, slew rate is not generally of great concern. If the signal is for an electronic event, (e.g., current, power output) a fast transition may be needed.

Common-mode rejection—a measure of

unwanted signal rejection and the amp's ability to extract a signal from surrounding DC, power line or other electrical noise.

The difference amplifier is a moderate input impedance, closed-loop, fixed-gain block that allows the acquisition of signals in the presence of ground loops and noise. These devices can be used in a variety of precision, general-purpose, audio, low-power, highspeed and high-common-mode voltage applications.

Difference Amplifier

The basic difference amplifier employs an op amp and four on-chip, precision, laser trimmed resistors. The INA132, for example, operates on 2.7V to 36V supplies and consumes only 160µA. It has a differential gain of 1 and high common-mode rejection. The output signal can be offset by applying a voltage to the Ref pin. The output sense pin can be connected directly at the load to reduce gain error. Because the resistor network divides down the input voltages, difference amplifiers can operate with input signals that exceed the power supplies.

High Common-Mode Voltage Difference Amplifier Topology

A five-resistor version of the simple difference amplifier results in a device that can operate with very high levels of common-mode voltage—far beyond its power supply rails. For example, the INA117 can sense differential signals in the presence of common-mode voltages as high as ±200V while being powered from ±15V. This device is very useful in measuring current from a high-voltage power supply through a highside shunt resistor.

Design Considerations

Power supply—common-mode voltage is

always a function of the supply voltage. The INA103 instrumentation amplifier is designed to operate on voltage supplies up to ±25V, while the INA122 difference amp can be operated from a 2.2V supply.

Output voltage swing—lower supply

voltage often drives the need to maximize dynamic range by swinging close to the rails.

Should I Use a Difference Amplifier or Instrumentation Amplifier?

Difference amplifiers excel when measuring signals with common-mode voltages greater

than the power supply rails, when there is a low power requirement, when a small package is needed, when the source impedance is low or when a low-cost differential amp is required. The difference amp is a building block of the instrumentation amp.

Instrumentation amplifiers are designed to amplify low-level differential signals where the maximum common-mode voltage is within the supply rails. Generally, using an adjustable gain block, they are well-suited to single-supply applications. The three-op-amp topology works well down to Gain = 1, with a performance advantage in AC CMR. The two-op-amp topology is appropriate for tasks requiring a small package footprint and a gain of 5 or greater. It is the best choice for low-voltage, single-supply applications.

Analog Current Shunt Monitors

➔

Current shunt monitors are a unique class of high common-mode voltage difference amplifiers that have the ability to operate on single, low-voltage supplies.

Current shunt monitors have a common-mode voltage range that is independent of power supply (as opposed to classical difference amplifiers where the common-mode voltage range is proportional to power supply voltage). Unlike most high commonmode voltage difference amplifiers, current sense shunt monitors have gains for sensing low differential voltages (50mV to 100mV).

Current sensing can be done on either the low-side (ground) or high-side (power supply). Low-side sensing is simple and requires no special components, but it often cannot be used because it either disturbs ground or requires additional wiring. Current shunt monitors are intended to make it easy to implement high-side current sensing. Discrete solutions to high-side sensing are difficult and costly to implement.

Common-Mode Voltage

The common-mode voltage range is typically the first parameter to be considered and this breaks down into two basic categories of current shunt monitors: families that handle only positive common-mode voltages above +2.7V (with a choice of upper limits up to +60V); and a family that handles –16V to +80V. The ability to sense common-mode voltages at ground and below is required when the power supply that the current is being sensed from could get shorted out, or if the shunt resistor is in an inductive load that could be exposed to inductive kickback. In addition, a commonmode range to –16V allows the current shunt monitor to be used to sense current in –12V to –15V power supplies. Lastly, it easily withstands battery reversals in 12V automotive applications.

Current Output vs. Voltage Output

Another broad category is the type of output. The current output families enable the gain to be set by selecting the value of an external load resistor. The fastest current shunt monitor is the INA139 or INA169. Current output INA170, and current output devices have a minimum common-mode voltage of +2.7V, with a maximum up to +60V.

Voltage output current shunt monitors have the advantage of a buffered voltage output which eliminates the need for an additional op amp in many applications. These devices are available in fixed gains of 14, 20, 50 and

100. The voltage output current shunt monitors all have a common-mode range of –16V to +80V.

Instrumentation Amplifiers

The instrumentation amplifier (IA) is a high input impedance, closed-loop, fixed- or adjustable-gain block that allows for the amplification of low-level signals in the presence of common-mode errors and noise. TI offers many types of instrumentation amplifiers including single-supply, low-power, high-speed and low-noise devices. These instrumentation amplifiers are available in either the traditional three-op-amp or in the cost-effective two-op-amp topology.

Three-Op-Amp Version

The three-op-amp topology is the benchmark for instrumentation amplifier performance. These devices provide a wide gain range (down to G = 1) and generally offer the highest performance. Symmetrical inverting and non-inverting gain paths provide better common-mode rejection at high frequencies. Some types use current-feedback-type input op amps which maintain excellent bandwidth in high gain.

Two-Op-Amp Version

The two-op-amp topology can provide wider common-mode voltage range, especially in low-voltage, single-supply applications. Their simpler internal circuitry allows lower cost, lower quiescent current and smaller package sizes. This topology, however, does not lend itself to gains less than four (INA125) or five (all others).

Design Considerations

Supply voltage—TI has developed a series of

low-voltage, single-supply, rail-to-rail instrumentation amps suitable for a wide variety of applications requiring maximum dynamic signal range.

Gain requirement—for high-gain applications

consider a low total noise device, because drift, input bias current and voltage offset all contribute to error.

Common-mode voltage range—the voltage

input range over which the amplifier can operate and the differential pair behaves as a linear amplifier for differential signals.

Input bias current—can be an important

factor in many applications, especially those sensing a low current or where the sensor impedance is very high. The INA116 requires only 3fA typical of input bias current.

Offset voltage and drift—IAs are

generally used in high-gain applications, where any amp errors are amplified by the circuit gain. These errors can become significant unless VOSand drift performance are considered in the device selection. Bipolar input stage INAs generally have smaller error contribution from offset and drift in low source impedance applications.

Current-feedback vs. voltage-feedback input stage—appropriate for designers needing

higher bandwidth or a more consistent 3dB rolloff frequency over various gain settings. The INA128 and INA129 provide a significantly higher 3dB rolloff frequency than

voltage-feedback input stage instrumentation amps and have a 3dB rolloff at essentially the same frequency in both G = 1 and G = 10 configurations.

Technical Information

IAs output the difference accurately between the input signals providing Common-Mode Rejection (CMR). It is the key parameter and main purpose for using this type of device. CMR measures the device’s ability to reject signals that are common to both inputs.

IAs are often used to amplify the differential output of a bridge sensor, amplifying the tiny bridge output signals while rejecting the large common-mode voltage. They provide excellent accuracy and performance, yet require minimal quiescent current. Gain is usually set with a single external resistor.

In some applications unwanted common-mode signals may be less conspicuous. Real-world ground interconnections are not perfect. What may, at first, seem to be a viable single-ended amplifier application can become an accumulation of errors. Error voltages caused by currents flowing in ground loops sum with the desired input signal and are amplified by a single-ended input amp. Even very low impedance grounds can have induced voltages from stray magnetic fields. As accuracy requirements increase, it becomes more difficult to design accurate circuits with a single-ended input amplifier. The differential input instrumentation amplifier is the answer.

The three-op-amp topology is the benchmark for instrumentation amplifier performance.

Two-op-amp topology provides wider common-mode range in low-voltage, single-supply applications.
