DESCRIPTION
The INA103 is a very low noise, low distortion mono­lithic instrumentation amplifier. Its current-feedback circuitry achieves very wide bandwidth and excellent dynamic response. It is ideal for low-level audio signals such as balanced low-impedance microphones. The INA103 provides near-theoretical limit noise per­formance for 200 source impedances. Many indus­trial applications also benefit from its low noise and wide bandwidth.
Unique distortion cancellation circuitry reduces dis­tortion to extremely low levels, even in high gain. Its balanced input, low noise and low distortion provide superior performance compared to transformer-coupled microphone amplifiers used in professional audio equipment.
The INA103’s wide supply voltage (±9 to ±25V) and high output current drive allow its use in high-level audio stages as well. A copper lead frame in the plastic DIP assures excellent thermal performance.

ELECTROSTATIC DISCHARGE SENSITIVITY
Any integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degrada­tion to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet
published specifications.

APPLICATIONS INFORMATION
Figure 1 shows the basic connections required for operation. Power supplies should be bypassed with 1µF tantalum capacitors near the device pins. The output Sense (pin 11) and output Reference (pin 7) should be low impedance connections. Resistance of a few ohms in series with these connections will degrade the common-mode rejection of the amplifier. To avoid oscillations, make short, direct connection to the gain set resistor and gain sense connections. Avoid running output signals near these sensitive input nodes.
INPUT CONSIDERATIONS
Certain source impedances can cause the INA103 to oscil­late. This depends on circuit layout and source or cable characteristics connected to the input. An input network consisting of a small inductor and resistor (Figure 2) can greatly reduce the tendancy to oscillate. This is especially
®
INA103
useful if various input sources are connected to the INA103. Although not shown in other figures, this network can be used, if needed, with all applications shown.
GAIN SELECTION
Gains of 1 or 100V/V can be set without external resistors. For G = 1V/V (unity gain) leave pin 14 open (no connec­tion)—see Figure 4. For G = 100V/V, connect pin 14 to pin 6—see Figure 5.
Gain can also be accurately set with a single external resistor as shown in Figure 1. The two internal feedback resistors are laser-trimmed to 3k within approximately ±0.1%. The temperature coefficient of these resistors is approximately 50ppm/˚C. Gain using an external R

FIGURE 1. Basic Circuit Configuration.
Accuracy and TCR of the external R
will also contribute to
G
gain error and temperature drift. These effects can be di­rectly inferred from the gain equation.
Connections available on A
and A2 allow external resistors
1
to be substituted for the internal 3k feedback resistors. A precision resistor network can be used for very accurate and stable gains. To preserve the low noise of the INA103, the value of external feedback resistors should be kept low. Increasing the feedback resistors to 20k would increase noise of the INA103 to approximately 1.5nV/Hz. Due to the current-feedback input circuitry, bandwidth would also be reduced.
NOISE PERFORMANCE
The INA103 provides very low noise with low source impedance. Its 1nV/Hz voltage noise delivers near theo­retical noise performance with a source impedance of 200.
Relatively high input stage current is used to achieve this low noise. This results in relatively high input bias current and input current noise. As a result, the INA103 may not provide best noise performance with source impedances greater than 10k. For source impedance greater than 10k, consider the INA114 (excellent for precise DC applica­tions), or the INA111 FET-input IA for high speed applica­tions.
FIGURE 2. Input Stabilization Network.
Offset voltage can be trimmed with the optional circuit shown in Figure 3. This offset trim circuit primarily adjusts the output stage offset, but also has a small effect on input stage offset. For a 1mV adjustment of the output voltage, the input stage offset is adjusted approximately 1µV. Use this adjustment to null the INA103’s offset voltage with zero differential input voltage. Do not use this adjustment to null offset produced by a sensor, or offset produced by subse­quent stages, since this will increase temperature drift.
To offset the output voltage without affecting drift, use the circuit shown in Figure 4. The voltage applied to pin 7 is summed at the output. The op amp connected as a buffer provides a low impedance at pin 7 to assure good common­mode rejection.
Figure 5 shows a method to trim offset voltage in AC­coupled applications. A nearly constant and equal input bias current of approximately 2.5µA flows into both input termi­nals. A variable input trim voltage is created by adjusting the balance of the two input bias return resistances through which the input bias currents must flow.
OFFSET ADJUSTMENT
Offset voltage of the INA103 has two components: input stage offset voltage is produced by A stage offset is produced by A offset are laser trimmed and may not need adjustment in many applications.

Figure 6 shows an active control loop that adjusts the output offset voltage to zero. A

produces an offsetting voltage applied to one input of the INA103. This produces a –6dB/octave low frequency roll­off like the capacitor input coupling in Figure 5.
COMMON-MODE INPUT RANGE
For proper operation, the combined differential input signal and common-mode input voltage must not cause the input amplifiers to exceed their output swing limits. The linear input range is shown in the typical performance curve “Maximum Common-Mode Voltage vs Output Voltage.” For a given total gain, the input common-mode range can be increased by reducing the input stage gain and increasing the output stage gain with the circuit shown in Figure 7.

(a) AD625 G = 1, VIN = ±15V, RL = 600
A common problem with many IC op amps and instrumentation amplifiers is shown in (a). Here, the amplifier’s input is driven beyond its linear common-mode range, forcing the output of the amplifier into the supply rails. The output then “folds back”, i.e., a more positive input voltage now causes the output of the amplifier to go negative. The INA103 has protection circuitry to prevent fold-back, and as shown in (b), limits cleanly.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
