OPA4134UA/2K5

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4134UA/2K5 is a quad SoundPlus high-performance audio operational amplifier manufactured by Texas Instruments. It features a true FET input stage providing low input bias current of 5 pA and low voltage noise density of 8 nV/sqrt Hz. The device offers a gain-bandwidth product of 8 MHz, a slew rate of 20 V/us, and an open-loop gain of 120 dB at 600 ohms load. Total harmonic distortion plus noise is specified at 0.00015%. It operates on dual supplies ranging from +/- 2.5V to +/- 18V or single supplies from 5V to 36V. The package is a 14-pin SOIC with an operating temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix /2K5 indicates tape and reel packaging containing 2500 units per manufacturer specifications. Confirm the device status as active or obsolete through official Texas Instruments channels before finalizing procurement plans. Ensure compatibility with standard surface mount assembly processes for the 14-SOIC package.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing multi-channel audio systems requiring low noise and high speed. The quad configuration reduces board space compared to individual op-amps. Consider the 14-SOIC package constraints for thermal management and PCB layout. Verify that the required supply voltage falls within the specified +/- 2.5V to +/- 18V range for optimal performance.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA134 family of ultra-low distortion audio operational amplifiers. The quad variant integrates four independent amplifiers in a single package. The 'UA' designation specifies the plastic SOIC package type. The '/2K5' suffix denotes the specific shipping configuration provided by the manufacturer.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible variants include OPA4134UAE4 and OPA4134UA. These parts share identical electrical characteristics and pinouts. Verify package dimensions and lead finish requirements when substituting to ensure mechanical compatibility.
