## Summary description

Texas Instruments OPA134UA is a single-channel operational amplifier with very low total harmonic distortion (THD 0.00008%) and an 8 MHz bandwidth. Compact package dimensions (5 × 3.98 × 1.5 mm) make it suitable for audio and precision analog signal conditioning, low-noise preamplifiers, and instrumentation applications where linearity and low distortion are required.

## Long description

Texas Instruments OPA134UA is a single-channel operational amplifier designed for low-distortion, high-fidelity analog signal conditioning. With an ultra-low total harmonic distortion of 0.00008% and a bandwidth of 8 MHz, this op amp targets audio and precision applications that require linear response and low noise. The device comes in a compact package measuring 5 × 3.98 × 1.5 mm and supports a wide supply voltage range from ±2.5 V to ±18 V, making it suitable for a broad range of system designs that demand high open-loop gain and stable performance.
Advantages
The OPA134UA combines very low THD and low input noise density (8 nV/√Hz) with true FET input characteristics, providing low input bias current (typical 5 pA) and minimal loading of source circuits. A high open-loop gain (about 120 dB into 600 Ω), a 20 V/µs slew rate and an 8 MHz bandwidth ensure accurate reproduction of audio signals and faithful amplification of small analog signals. Compact physical dimensions and a wide supply range add flexibility for integration into space-constrained and battery-powered designs.
Suitable for
 High-fidelity audio preamplifiers and buffers
 Low-noise microphone and instrument preamplifiers
 Precision analog signal conditioning and filtering
 Measurement and instrumentation front-ends requiring low distortion

How to use
Use the OPA134UA according to standard operational amplifier design practices: provide appropriate power supply decoupling close to the device, follow recommended input and output protection measures described in the device datasheet, and design feedback networks to achieve the required closed-loop gain and stability. Select resistor and capacitor values that keep noise and offset within acceptable limits for your application, and observe the device input common-mode and output swing limitations relative to the chosen supply rails.
Usage recommendations
For best audio and precision performance, place supply bypass capacitors near the power pins, avoid long unshielded input traces, and design the PCB layout to minimize ground loops and coupling. Choose feedback and input resistor values to balance noise, bandwidth, and source loading. When operating near the supply rails, verify headroom and output swing in your circuit conditions.
