OPA2344UA

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2344UA is a dual-channel, low-power, single-supply operational amplifier from Texas Instruments' MicroAmplifier series. It features rail-to-rail input and output capabilities within a compact 8-SOIC package. Key electrical specifications include a gain-bandwidth product of 1 MHz, a slew rate of 800 mV/us, and an input offset voltage of 1 mV. The device operates on supply voltages ranging from 2.5 V to 5.5 V with a typical quiescent current of 150 uA per channel. It supports an operating temperature range from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape-and-reel packaging versus tube quantities. Ensure the supplier provides valid traceability documentation matching the part number OPA2344UA.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing single-supply systems requiring rail-to-rail performance with low power constraints. Compare against other MicroAmplifier variants if higher bandwidth or lower noise density is required. Ensure the application voltage remains within the 2.5 V to 5.5 V limits to maintain specified electrical characteristics.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPA2344 family of low-power operational amplifiers. It shares architectural similarities with other members like the OPA2343 but differs in speed and drive capability. The SOIC-8 package allows for surface-mount integration in space-constrained PCB layouts common in modern consumer electronics.
