What are the key features of LM7322QMAX/NOPB?
- AEC-Q100 automotive qualified dual op-amp ensuring reliable performance from -40 degrees C to +125 degrees C in vehicle ECU environments
- 80 dB typical common-mode rejection ratio with 72 dB minimum supporting precision differential signal conditioning on noisy automotive bus lines
- 0.2 µA maximum input bias current at 25 degrees C enabling accurate high-impedance sensor interfaces with minimal loading error
- Rail-to-rail output swing in SOIC-8 package maximising dynamic range in single-supply 3.3 V and 5 V signal chains
What is LM7322QMAX/NOPB used for?
The LM7322QMAX/NOPB is designed for automotive ECU sensor signal conditioning, battery management current-sense amplification, and precision comparator stages in powertrain and chassis control modules operating over the -40 degrees C to +125 degrees C AEC-Q100 temperature range. Its high CMRR of 80 dB allows it to reject common-mode noise from automotive wiring harnesses while faithfully amplifying millivolt-level differential sensor signals. The device is also used in industrial instrumentation front-ends, 4 mA to 20 mA loop receivers, and precision active filter stages that demand low offset drift and stable bias current over wide temperature swings.

Frequently Asked Questions
What CMRR does LM7322QMAX/NOPB provide, and how does that affect rejection of automotive harness noise?
LM7322QMAX/NOPB achieves a typical 80 dB CMRR with a guaranteed minimum of 72 dB, meaning a 1 V common-mode noise spike injected by the automotive harness is attenuated to less than 250 µV at the output. This level of rejection is essential for differential sensor lines in engine management systems where 12 V alternator ripple and ignition transients couple onto signal wires running near high-current cables.
Over what temperature range is LM7322QMAX/NOPB specified, and which automotive grades does it cover?
The device is specified from -40 degrees C to +125 degrees C, meeting AEC-Q100 Grade 1 requirements for automotive electronics in instrument clusters, transmission ECUs, and body control modules. The input bias current stays below 1.5 µA across the full temperature range, ensuring that high-impedance resistive divider networks used in sensor interfaces retain accuracy without adding significant current-mode error terms.
How does the 0.2 µA input bias current of LM7322QMAX/NOPB influence the design of a high-impedance pH or pressure sensor interface?
With a maximum input bias current of 0.2 µA at 25 degrees C, the LM7322QMAX/NOPB introduces less than 200 µV of offset error across a 1 MΩ source impedance, which is below the 1 mV accuracy threshold required for most 12-bit ADC front-ends. This allows designers to use larger source resistors in anti-aliasing filters or signal attenuators without degrading measurement precision, reducing BOM cost compared to JFET-input amplifiers.
For a 4 mA to 20 mA industrial current-loop receiver, why is LM7322QMAX/NOPB a viable single-supply solution?
The rail-to-rail output swing allows the amplifier to deliver a full 0 V to 5 V output when powered from a single 5 V supply, covering the complete 4 mA to 20 mA conversion range with over 98% dynamic range utilisation. The 80 dB CMRR simultaneously rejects ground potential differences of up to 100 mV between transmitter and receiver nodes, which is common in industrial plants where cabinet ground planes can differ by tens of millivolts.
