OPA2344UA/2K5

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2344UA/2K5 is a dual-channel, low-power, single-supply operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 1 MHz and a slew rate of 800 mV/us. The device operates within a supply voltage range of 2.5 V to 5.5 V with a quiescent current of 150 uA per channel. Key electrical specifications include an input offset voltage of 1 mV, input bias current of 10 pA, and common-mode rejection ratio of 92 dB. Input and output voltage noise densities are 30 nV/sqrt Hz and 0.0005 pA/sqrt Hz respectively. It supports rail-to-rail input and output operation in an SOIC-8 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the SOIC-8 package dimensions align with PCB footprint constraints. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing low-voltage, single-supply circuits requiring moderate bandwidth and low power dissipation. The rail-to-rail I/O feature makes it suitable for interfacing with ADCs or sensors operating near ground or positive supply rails. Consider the 150 uA quiescent current for battery life calculations. Compare performance metrics against higher-speed or lower-noise alternatives if application demands exceed the 1 MHz gain-bandwidth product.
