LM2904DGKR

Instrumentation, Op Amps, Buffer Amps Overview

The LM2904DGKR is a dual general-purpose operational amplifier from the ROHM TROPHY Series, designed for extended industrial applications. It integrates two independent op-amp circuits and phase compensation capacitors on a single chip. The device supports a wide operating voltage range of +3V to +32V for single supply or ±1.5V to ±16V for dual supply configurations. Key electrical characteristics include a typical unity-gain bandwidth of 700 kHz, a slew rate of 0.3 V/µs, and an input bias current of 20 nA at 25°C. It operates within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific manufacturer source, as this part number is also distributed by Texas Instruments in similar packaging. Confirm RoHS compliance status and ensure the package type matches the required PCB footprint. Check for any recent product change notices regarding manufacturing sites or material composition updates before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when an industrial-grade dual operational amplifier is required that supports ground-sensing inputs. It is suitable for designs needing a wide supply voltage range and low quiescent current. Ensure the application does not require rail-to-rail output swing, as this device has a limited output voltage range relative to the supply rails.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the Universal Standard family of monolithic ICs, which also includes the LM358, LM324, and LM2902 series. These devices share similar architectural features but differ in temperature grades and channel counts. The LM2904 specifically targets extended industrial environments compared to the commercial grade LM358.
