What is LM2902KAVQDRDL used for?
The LM2902KAVQDRDL is used in automotive signal conditioning chains for sensor amplification, threshold detection, and analog filtering in powertrain, body electronics, and HVAC systems requiring AEC-Q100 qualification. Its quad channel configuration and 0.8 mA supply current make it effective for multi-channel battery management analog front-ends and current sensing circuits in electric vehicle subsystems. The SOIC-14 package allows integration into automotive ECU PCBs where four op-amp functions share a single footprint, reducing component count and board area.

Frequently Asked Questions
What automotive qualification does LM2902KAVQDRDL carry and what does AEC-Q100 compliance require?
LM2902KAVQDRDL holds AEC-Q100 qualification, the Automotive Electronics Council standard for IC stress testing covering temperature cycling from -40°C to +125°C, electrostatic discharge, and humidity bias testing. This qualification ensures the quad op-amp meets automotive reliability requirements for under-hood sensor amplifiers, ECU analog signal chains, and powertrain control modules operating across the full automotive temperature range.
How does the 0.8 mA total supply current of LM2902KAVQDRDL benefit always-on automotive subsystem designs?
The 0.8 mA typical quiescent current for all 4 amplifier channels combined means each channel draws approximately 200 µA, making LM2902KAVQDRDL suitable for sleep-mode and standby circuits in body electronics that must remain active while drawing minimal battery current. Over a 30-day vehicle park period, 0.8 mA continuous draw consumes less than 580 mAh, preserving battery charge in keyless entry and alarm system amplifier stages.
What supply voltage range does LM2902KAVQDRDL support across automotive operating conditions?
LM2902KAVQDRDL operates from 3 V to 32 V single supply, covering the nominal 12 V automotive rail as well as load dump transients reaching up to 28 V in conventional 12 V vehicle electrical systems. This wide voltage tolerance eliminates the need for voltage regulation ahead of the op-amp in many automotive sensor interface designs, reducing BOM cost and PCB area in space-constrained ECU analog front-ends.
How does the quad-channel LM2902KAVQDRDL reduce BOM cost compared to using four discrete single-channel op-amps?
By integrating 4 op-amp channels in a single 14-pin SOIC-14 package, LM2902KAVQDRDL replaces four individual single-channel devices such as LM321, each in separate SOT-23-5 packages. This consolidation reduces component count from 4 packages to 1, cutting placement time in SMT assembly, reducing total package footprint by roughly 60%, and lowering per-channel unit cost compared to procuring four separate AEC-Q100 single op-amps.
For a multi-channel 4-20 mA industrial current loop receiver, how well does LM2902KAVQDRDL fit the design requirements?
LM2902KAVQDRDL is well-matched for 4-20 mA current loop receiver designs requiring 4 channels in one package operating from 24 V industrial supply rails. Each channel can convert the 1 V to 5 V drop across a 250 Ω sense resistor into a 0 V to 5 V output, and the 0.8 mA total quiescent current keeps power dissipation below 20 mW at 24 V, suitable for DIN-rail analog input modules and PLC sensor interface cards.
