LM2902KDBRG4

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902KDBRG4 is a quad general-purpose operational amplifier manufactured by Texas Instruments. It features four independent amplifiers within a single package, designed for low power consumption and wide supply voltage operation ranging from 3 V to 32 V. The device offers a gain-bandwidth product of 1.2 MHz and a slew rate of 0.5 V/µs. Key electrical specifications include an input offset voltage of 3 mV, input bias current of 20 nA, and output current capability of 60 mA per channel. It operates reliably across a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix KDBRG4 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the component meets the required AEC-Q100 grade if used in automotive contexts. Check for end-of-life notices or production changes as this family has undergone PCN updates. Ensure the 14-SSOP package dimensions match the PCB footprint requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple low-power amplifiers are needed in a small surface-mount form factor. It serves as a direct replacement for the LM2902KD series in commercial and industrial designs. Consider the 60 mA output drive capability for driving moderate loads without external buffering. Verify that the 1.2 MHz bandwidth is sufficient for the target signal frequencies.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LM2902/LM324 family of quadruple operational amplifiers. It shares functional similarities with the LM2902N but utilizes a different package type. The 'G4' suffix typically indicates lead-free and RoHS compliance. It is distinct from the LM124 and LM324 variants primarily through its specific automotive qualification and packaging configuration.
