OPA4374AIDRG4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4374AIDRG4 is a quad, wideband CMOS operational amplifier manufactured by Texas Instruments. It features rail-to-rail input and output capabilities with a gain-bandwidth product of 6.5 MHz and a slew rate of 5 V/µs. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, drawing a typical supply current of 585 µA per channel. Key electrical specifications include an input offset voltage of 1 mV, input bias current of 0.5 pA, and a common-mode rejection ratio of 90 dB. It is housed in a 14-pin SOIC package and supports an operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'G4' indicates lead-free packaging compliant with RoHS standards. Confirm the 'R' designation corresponds to tape-and-reel packaging suitable for automated surface-mount assembly. Ensure the 'A' grade specification matches the required offset voltage and drift tolerances for the target application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple channels are required within a compact footprint. The rail-to-rail I/O characteristic makes it suitable for low-voltage single-supply designs where signal swing must utilize the full supply range. Consider the 6.5 MHz bandwidth as sufficient for moderate-speed applications without requiring higher-power alternatives.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA4374 family of CMOS operational amplifiers. It shares core electrical characteristics with variants such as the OPA4374AID and OPA4374AIDR, differing primarily in packaging format and manufacturing compliance markings. The quad configuration distinguishes it from dual-channel counterparts like the OPA2374.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes within the same family include OPA4374AID and OPA4374AIDR. Verify that alternative packages maintain the same thermal and mechanical constraints.
