General Description

The MAX9000 family features the combination of a highspeed operational amplifier, a 185ns comparator, and a precision 1.230V reference. These devices operate from a single +2.5V to +5.5V supply and draw less than 500µA of quiescent current. The MAX9001/MAX9004 feature a shutdown mode that reduces supply current to 2µA and puts the outputs into a high-impedance state, making them ideal for portable and battery-powered applications.

The amplifiers in the MAX9000/MAX9001/MAX9002 are unity-gain stable with a 1.25MHz gain-bandwidth product, while the amplifiers in the MAX9003/MAX9004/MAX9005 are stable for closed-loop gains of +10V/V or greater with an 8MHz gain-bandwidth product. The input commonmode voltage extends from 150mV below the negative supply to within 1.2V of the positive supply for the amplifier, and to within 1.1V for the comparator. The amplifier and comparator outputs can swing Rail-to-Rail®and deliver up to ±2.5mA and ±4.0mA, respectively, to an external load while maintaining excellent DC accuracy. The unique design of the comparator output stage substantially reduces switching current during output transitions, virtually eliminating power-supply glitches.

The comparator’s ±2mV of built-in hysteresis provides noise immunity and prevents oscillations even with a slow-moving input signal. The MAX9000/MAX9001/ MAX9003/MAX9004 have an internal 1.230V ±1% precision reference with a low 8ppm/°C temperature coefficient that can sink or source up to 1mA. The amplifier and reference are stable with capacitive loads up to 250pF and 100nF, respectively. The comparator’s inverting input is internally connected to the reference output in the MAX9000/MAX9003.

_______________Detailed Description

The MAX9001–MAX9005 are combinations of a highspeed operational amplifier, a 185ns comparator, and a 1%-accurate, 8ppm/°C, 1.230V reference. The devices are offered in space-saving 8-pin and 10-pin µMAX packages. The comparator’s inverting input is internally connected to the reference output in the MAX9000/MAX9003. The MAX9002/MAX9005 do not have an internal reference, but the inverting input of the comparator is available externally. The MAX9001/MAX9004 include both the inverting input and the reference output. The MAX9000/ MAX9001/MAX9003/MAX9004 typically consume only 410µA of quiescent current, while the MAX9002/ MAX9004 typically consume 340µA. These low-power, Rail-to-Rail devices provide excellent AC and DC performance and are ideally suited to operate from a single supply. The MAX9001/MAX9004 feature a shutdown mode that sets the outputs in a high-impedance state and reduces the supply current to 2µA, making these devices ideal for portable and battery-powered systems.

Op Amp

The op amps in the MAX9000/MAX9001/MAX9002 are unity-gain stable with a gain-bandwidth product of

1.25MHz and a slew rate of 0.85V/µs. The amplifiers in the MAX9003/MAX9004/MAX9005 are stable at closedloop gains greater than or equal to 10V/V, with a gainbandwidth product of 8MHz and a slew rate of 6.0V/µs.

The common-mode input voltage range extends from 150mV below the negative rail to within 1.2V of the positive rail. The amplifier output does not undergo phase reversal when the common-mode input range is exceeded, and the input impedance is relatively constant for input voltages within both supply rails. The MOS differential inputs of the amplifiers feature extremely high input impedance and ultra-low input bias currents. The CMOS output stage achieves true rail-to-rail operation; the outputs swing to within a few millivolts of the supply rails, thus extending the dynamic range. A proprietary design achieves high open-loop gain, enabling these devices to operate at low quiescent currents yet maintain excellent DC and AC characteristics under various load conditions. These devices have been designed to maintain low offset voltage over the entire operating-temperature, commonmode, and supply-voltage ranges.

Comparator

The common-mode input range extends from 150mV below the negative rail to within 1.1V of the positive rail. The bipolar differential inputs of the comparator feature high input impedance and low input bias currents. The comparators are designed to maintain low offset voltage over the entire operating-temperature, commonmode, and supply-voltage ranges. In the MAX9000/ MAX9003, the comparator’s inverting input is internally connected to the reference output.

The CMOS output stage achieves true rail-to-rail operation; the outputs swing to within a few millivolts of the supply rails. The comparator’s propagation delay is 185ns and is a function of the overdrive (see

Typical

Operating Characteristics

). TTL/CMOS compatibility is maintained even with a ±4mA output load. A proprietary design of the output stage substantially reduces the cross-conduction current during output transitions, thereby minimizing power-supply glitches typical of most comparators. In addition, the comparator’s ±2mV of built-in hysteresis provides noise immunity and prevents unstable outputs even with slow-moving input signals.

Voltage Reference

The 1%-accurate, precision 1.230V internal bandgap reference in the MAX9000/MAX9001/MAX9003/ MAX9004 achieves an 8ppm/°C temperature coefficient (tempco). The reference can sink or source 1mA of load current with excellent load regulation. The output typically changes only 60µV for a 3V change in input voltage (line regulation). The reference is stable for capacitive loads up to 100nF.

Applications Information

The MAX9000–MAX9005 offer excellent performance and low power consumption, and are available in space-saving µMAX packages. The following section provides some practical application guidelines.

Bypassing and Layout

The MAX9000–MAX9005 operate from a +2.5V to +5.5V single supply or from ±1.25V to ±2.75V dual supplies. (In the MAX9000/MAX9001/MAX9003/MAX9004, the reference voltage is referred to as VSS.). For singlesupply operation, bypass the power supply with a

0.1µF capacitor. For dual supplies, bypass each supply to ground. Bypass with capacitors as close as possible to the device to minimize lead inductance and noise. Use a low-inductance ground plane if possible. A printed circuit board with a ground plane is recommended. Avoid using wire-wrap boards, breadboards, or IC sockets. For heavy loads at the comparator’s and/or

amplifier’s output, add a 1µF to 10µF power-supply bypass capacitor.

The device has a high degree of isolation between the various blocks. To maintain isolation, careful layout is required. Take special precautions to avoid crossing signal traces, especially from the outputs to the inputs. For sensitive applications, shielding might be required. In addition, stray capacitance may affect the stability and frequency response of the amplifier. Decrease stray capacitance by minimizing lead lengths in the board layout, as well as placing external components as close to the device as possible.

Op-Amp Frequency Stability

Driving large capacitive loads can cause instability in most low-power, rail-to-rail output amplifiers. These amplifiers are stable with capacitive loads up to 250pF in their minimum gain configuration. Stability with higher capacitive loads can be improved by adding an isolation resistor in series with the op-amp output, as shown in Figure 2. This resistor improves the circuit’s phase margin by isolating the load capacitor from the amplifier’s output. Figures 3 and 4 show the response of the amplifier with and without an isolation resistor, respectively.

The total capacitance at the op amp’s inputs (input capacitance + stray capacitance) along with large-value feedback resistors can cause additional poles within the amplifier’s bandwidth, thus degrading the phase margin. To compensate for this effect, place a 2pF to 10pF capacitor across the feedback resistor, as shown in Figure 5.

LOAD

Figure 2. Isolation Resistors to Drive Capacitive Loads

MAX9000–MAX9005

Reference Bypassing

While the internal reference is stable with capacitive loads up to 100nF, it does not require an output capacitor for stability. However, in applications where the load or the supply could experience large step changes, an output capacitor reduces the amount of overshoot and improves the circuit’s transient response.

Comparator Input Stage

The comparator’s input bias current is typically 8nA. To reduce the offset error caused by the bias current flowing through the external source impedance, match the effective impedance seen by each input. High source impedance together with the comparator’s input capacitance can increase the propagation delay through the

comparator. The outputs do not undergo phase reversal when the input common-mode range is exceeded, and the input impedance is relatively constant for input voltages within both supply rails.

Comparator Hysteresis

Built-in ±2mV hysteresis improves the comparator’s noise immunity. It prevents unstable outputs with slowmoving or noisy input signals. If additional hysteresis is required, add positive feedback as shown in Figure 6. This configuration increases the hysteresis band to desired levels, but also increases power consumption and slows down the output response.

To add hysteresis, use the following procedure: Step 1: The device’s input bias current can be as high

as 80nA. To minimize error due to the input bias, choose a value for R2 of 100kΩ (V

REF

/ R2), which

allows a current of 12.33µA at the upper trip point. Step 2: Choose the width of the hysteresis band. In this

example, choose 20mV for the added external hysteresis (V

EHYST

= 20mV). Total hysteresis = V

= 24mV.

R1 = R2 (V

- 2V

) / (VDD+ 2V

IHYST

)

where

IHYST

is the device’s internal hysteresis.

Step 3: Determine R1. If VDD= 5V, then R1 = 319Ω. Step 4: Check the hysteresis trip points. The following

equation represents the upper trip point (V

IN(H)

= [(R1 + R2) / R2] (V

REF

+ V

IHYST

) = 1.238V

The lower trip point is 24mV lower than upper trip point. V

IN(L

)

= 1.238V - 0.024V = 1.214V.

Comparator Propagation Delay

The comparator’s propagation delay is a function of the input overdrive voltage. Overdrive voltage is measured from beyond the edge of the offset and hysteresisdetermined trip points (see

Typical Operating

Characteristics

for a graph of Propagation Delay vs. Input Overdrive). High source impedance coupled with the comparator’s input capacitance increases the propagation delay. Large capacitive loads also increase the propagation delay.

Shutdown

(

SSHHDDNN

)

Shutdown is active-low enabled. The SHDN input for the MAX9001/MAX9004 can be taken above the posi-

tive supply without an increase in the SHDN input current, allowing them to be driven from independent logic circuits powered from a different supply voltage. However, the logic threshold voltage requirements must be met for proper operation. If SHDN is left unconnected, the device defaults to the enabled mode through an internal 4MΩ pull-up to V

. If SHDN is to be left unconnected, take proper care to ensure that no signals are coupled to this pin, as this may cause false triggering.

In shutdown mode, all outputs are set to a high-impedance state and the supply current reduces to 2µA. Enable times for the op amp, comparator, and reference are 2µs, 100ns, and 16µs, respectively. Shutdown delay times for the op amp, comparator, and reference are 200ns, 100ns, and 1µs, respectively (Figure 7).

________________Application Circuits

Radio Receiver for Alarms

and Detectors

Figure 8’s circuit is useful as a front end for RF alarms. An unshielded inductor is used with capacitors C1A, C1B, and C1C in a resonant circuit to provide frequency selectivity. The op amp from a MAX9003 amplifies the signal received. The comparator improves noise immunity, provides a signal-strength threshold, and translates the received signal into a pulse train. The tuned LC circuit in Figure 8 is set for 300kHz. The layout and routing of components for the amplifier should be tight to minimize 60Hz interference and crosstalk from the comparator. Metal shielding is recommended to prevent RFI from the comparator or digital circuitry from exciting the receiving antenna. The transmitting

antenna can be long parallel wires spaced about 7.2cm apart, with equal but opposite currents. Radio waves from this antenna are detectable when the receiver is brought within close proximity, but cancel out at greater distances.

Infrared Receiver Front End for

Remote Controls and Data Links

The circuit in Figure 9 uses the MAX9003 as a PIN photodiode preamplifier and discriminator for an infrared receiver. The op amp is configured as a Delyiannisnoise and eliminates low-frequency interference from sunlight, fluorescent lights, etc. This circuit is applicable for TV remote controls and low-frequency data links up to 200kbps. Carrier frequencies are limited to around 100kHz, as in the example circuit. Component layout and routing for the amplifier should be tight to reduce stray capacitance, 60Hz interference, and RFI from the comparator. Crosstalk from comparator edges distorts the amplifier signal. To minimize this effect, add a lowpass RC filter to the connection from the reference to the op amp’s noninverting input.

Signal Conditioning

For incoming signals that require filtering, the internal amplifier provides an opportunity to create an active filter. This may be required for relatively high-speed signals that require adequate filtering of high-speed carrier frequencies, harmonics, and external noise. In addition, the amplifier can be used to amplify the signal prior to digitizing it through the comparator to improve the comparator’s overall output response and improve its noise immunity.
