LM2904VQDR

Instrumentation, Op Amps, Buffer Amps Overview

The LM2904VQDR is a dual operational amplifier from the ROHM TROPHY Series, designed for extended industrial applications. It features two independent high-gain amplifiers with internal frequency compensation. The device supports a wide supply voltage range of +3 V to +32 V for single supplies and ±1.5 V to ±16 V for dual supplies. Key electrical characteristics include a typical input offset voltage of 3 mV, an input bias current of 20 nA, and a unity-gain bandwidth of 0.7 MHz. It operates within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix 'VQDR' corresponds to the specific package type and tape-and-reel configuration required for your assembly line. Confirm that the component meets the extended industrial temperature grade specifications necessary for your environmental conditions. Ensure compatibility with your PCB footprint dimensions before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when operation in harsh environments requiring temperatures up to +125°C is necessary. It is suitable for designs needing a wide dynamic supply voltage range without sacrificing low power consumption. Consider its rail-to-rail output capabilities relative to your load requirements and ensure the input common-mode range aligns with your signal levels near ground potential.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ROHM TROPHY Series, which integrates general-purpose operational amplifiers and comparators. The LM2904 family specifically targets extended industrial grades, distinguishing it from commercial variants like the LM358. It shares architectural similarities with industry-standard dual op-amps but offers enhanced thermal performance and robustness for demanding automotive or industrial control applications.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements may include other extended industrial grade dual op-amps such as the LM2904DR or LM2904PWR from the same manufacturer, provided they meet the specific voltage and temperature constraints.
