Quad op-amp with 1.2 MHz GBW and automotive temp range
The Texas Instruments LM2902KAVQDR is a quad general-purpose operational amplifier in a 14-SOIC package, part of the Automotive AEC-Q100 series. It delivers a gain-bandwidth product of 1.2 MHz and a slew rate of 0.5 V/µs, suiting it for signal conditioning in automotive and industrial control loops where four independent amplifiers share a single supply rail. Operating from a single supply of 3 V to 30 V, the device draws 1.4 mA total across all four channels — a reasonable quiescent budget for a multi-channel sensor interface running off an unregulated battery line.
Parametric fit for signal-chain design
Input offset voltage is 3 mV typical, and input bias current is 20 nA typical — these levels are adequate for non-critical sensor buffering or level-shifting stages where the signal amplitude is above 100 mV and source impedance is under 10 kΩ.
Lifecycle and compliance
The base product number is LM2902, which shares pinout and parametric compatibility with the broader LM2902 family. No official successor or cross-reference is required for this active part.
