OPA2379AIDRG4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2379AIDRG4 is a dual operational amplifier from Texas Instruments, packaged in an SOIC-8 surface-mount format. It operates on a supply voltage range of 1.8 V to 5.5 V with a typical quiescent current of 2.9 uA per channel. Key electrical parameters include a gain-bandwidth product of 90 kHz, a slew rate of 30 mV/us, and an input offset voltage of 1.5 mV. The device features rail-to-rail input and output capabilities, a common-mode rejection ratio of 100 dB, and an input bias current of 50 pA. It supports a maximum output current of 5 mA per channel and functions within a temperature range of -40 C to +125 C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Industrial data acquisition systems with single-supply operation

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as defined by Texas Instruments. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Check moisture sensitivity level (MSL) ratings to ensure proper storage and reflow soldering profiles are followed during assembly.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel configuration is required alongside ultra-low quiescent current specifications. It serves as a suitable alternative to single-channel variants like the OPA379 when space efficiency allows for an 8-pin package. Consider its 90 kHz bandwidth limit against higher-speed alternatives if signal frequency exceeds typical audio or slow sensor ranges.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA2379 family of micro-power operational amplifiers. It shares core electrical characteristics with the single-channel OPA379 but integrates two independent amplifiers into one package. The series is optimized for applications where power conservation is critical without sacrificing basic precision and signal integrity.
