## Summary description

Texas Instruments OPA2134UA/2K5 is a dual operational amplifier in an SOIC-8 package designed for audio applications. Supplied as a pair of op amps, it fits audio signal processing, preamplifiers, DAC output stages and headphone drivers where low distortion and precision are needed. Suitable for PCB mounting in consumer and professional audio equipment.

## Long description

The Texas Instruments OPA2134UA/2K5 is a dual operational amplifier in an SOIC-8 package engineered specifically for audio applications. It provides two precision op amp channels in a compact surface-mount format, offering low distortion and stable performance for signal conditioning tasks. The device is suitable for use on printed circuit boards in consumer and professional audio equipment where accurate reproduction and low noise are important.
Advantages
The OPA2134UA/2K5 delivers low total harmonic distortion and low noise, improving audio clarity in sensitive signal paths. Its dual-channel configuration reduces board space compared with separate single op amps, while the SOIC-8 surface-mount package simplifies automated PCB assembly. The amplifier design emphasizes linearity and precision, making it compatible with preamplifiers, DAC output stages, and headphone drivers that require consistent gain and low coloration.
Suitable for
Audio preamplifier stages
DAC output buffering and reconstruction filters
Headphone amplifiers and drivers
Line-level signal processing in mixers and equalizers
PCB-mounted consumer and professional audio equipment
Key specifications
Dual operational amplifier configuration (two channels)
SOIC-8 surface-mount package for PCB assembly
Optimized for low distortion and low noise audio performance
Designed for linearity and stable gain in audio frequency range
Solderable leads and compact footprint suitable for tight layouts
How to use
Mount the SOIC-8 package on a PCB designed for surface-mount components, following recommended footprint and soldering guidelines. Provide appropriate power supply decoupling close to the device to maintain stability and minimize noise. Configure the amplifier in the desired topology (inverting, non-inverting, or differential) with suitable feedback and input components, and ensure input/output coupling and protection are used where required by the application. Observe the device’s common-mode and output swing limits when selecting supply voltages and biasing networks.
Usage recommendations
Place bypass capacitors near the supply pins, avoid routing high-current traces near sensitive inputs, and use matched resistor networks for critical gain stages to preserve the low-distortion performance of the amplifier.
