OPA234U/2K5

Instrumentation, Op Amps, Buffer Amps Overview

The OPA234U/2K5 is a single-channel, low-power, precision operational amplifier manufactured by Texas Instruments. It features a rail-to-rail input and output capability, making it suitable for single-supply applications. Key electrical parameters include a maximum input offset voltage of 250 µV, a gain-bandwidth product of 1 MHz, and a slew rate of 0.6 V/µs. The device operates within a supply voltage range of 2.7 V to 5.5 V, with a typical quiescent current of 350 µA per channel. It is housed in an 8-pin SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix '2K5' indicates the tape-and-reel packaging quantity of 2000 units when ordering. Confirm the RoHS compliance status and lead times directly with the manufacturer or authorized distributors, as these details are subject to change. Ensure the component matches the required SOIC-8 package dimensions for your PCB layout.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring low power consumption and precision in single-supply environments. It is appropriate where rail-to-rail I/O is necessary but high-speed performance is not critical. Compare against the dual-channel OPA2343 if two amplifiers are needed in a similar footprint.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA234 series of low-cost, low-power operational amplifiers from Texas Instruments. The series is designed to replace older bipolar op-amps in single-supply applications, offering improved power efficiency while maintaining precision characteristics suitable for general-purpose analog signal processing tasks.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OPA234UA is a pin-compatible alternative available in a tube package instead of the reel format. For dual-channel requirements, the OPA2343 serves as a functional equivalent within the same family.
