Key Features
- AEC-Q100 automotive qualification ensures reliability across -40°C to +125°C temperature range for under-hood and body control applications
- 96 dB common-mode rejection ratio with 50 nA maximum bias current enables precision signal conditioning in noisy 12 V automotive environments
- Dual op-amp in 8-pin SOIC package provides 2 independent amplifier channels, reducing PCB space versus discrete solutions by 50%
Applications
The PLM2904BQDRQ1 is designed for automotive sensor interface circuits, battery monitoring comparators, and active filter stages in engine control units and body electronics modules. Its 96 dB CMRR and low 50 nA bias current make it well-suited for amplifying small differential signals from pressure, temperature, and position sensors on a 12 V automotive bus. The AEC-Q100 qualification ensures long-term reliability in the -40°C to +125°C temperature range typical of automotive environments.

Frequently Asked Questions
What automotive qualification standard does PLM2904BQDRQ1 meet and what temperature range does it cover?
The PLM2904BQDRQ1 is AEC-Q100 qualified for automotive applications, ensuring reliable operation across -40°C to +125°C ambient temperature. This qualification covers stress tests for electrostatic discharge, latch-up, and accelerated life testing, making it suitable for engine compartment and body control electronics.
How does the 96 dB CMRR of PLM2904BQDRQ1 help in rejecting noise on automotive 12 V sensor lines?
A 96 dB CMRR means the PLM2904BQDRQ1 attenuates common-mode noise by a factor of approximately 63,000, so 1 V of 12 V bus switching noise on both inputs appears as only 16 µV at the output. This allows accurate amplification of millivolt-level sensor signals such as pressure or temperature outputs without interference from alternator switching or ignition noise.
For a dual-channel comparator circuit in an automotive body control module, how does PLM2904BQDRQ1 reduce component count?
The PLM2904BQDRQ1 integrates 2 independent op-amps in a single 8-pin SOIC package, replacing 2 separate single-channel devices and saving one IC footprint. With a 4 mV maximum offset voltage and 50 nA bias current, it provides sufficient accuracy for threshold comparison of sensor voltages in 5 V logic-level body control circuits.
