LM2902WDT

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902WDT is a low-power quad operational amplifier manufactured by STMicroelectronics, housed in a 14-pin SOIC surface-mount package. It features a gain-bandwidth product of 1.3 MHz and a slew rate of 400 mV/us. The device operates on a single supply voltage ranging from 3 V to 30 V or dual supplies from ±1.5 V to ±15 V. Key electrical parameters include an input offset voltage of 7 mV, input bias current of 150 nA, and a common-mode rejection ratio of 80 dB. Each channel provides an output current of 40 mA with a typical operating supply current of 1.5 mA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'DT' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and quantity per reel. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering number with authorized distributors to validate authenticity and traceability before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits requiring multiple operational amplifiers within a compact surface-mount footprint. It is suitable for applications demanding low power consumption without sacrificing basic bandwidth performance. Consider the 7 mV input offset voltage and 400 mV/us slew rate limitations when evaluating suitability for precision analog signal processing tasks.
