TIOPA2134PA
Overview
The OPA2134PA is a high-performance, dual-channel FET-input operational amplifier specifically optimized for high-fidelity audio applications. It features ultra-low distortion and noise, making it a standard choice for signal paths that require high transparency and sonic accuracy. Operating from a wide supply range of +/-2.5V to +/-18V, this amplifier provides high open-loop gain and high output swing capacity.
Why Choose This Part
This op-amp combines a 20 V/us slew rate with a 8 MHz bandwidth, ensuring fast transient response in audio signals. Its true FET-input stage provides extremely low input bias current, reducing DC offset errors in high-impedance circuits. The PDIP-8 package offers ease of prototyping and replacement in legacy hardware or breadboard designs.
Applications
Key Specifications
Getting Started
When designing for audio, ensure the power supply is decoupled with 0.1uF ceramic capacitors placed as close to the V+ and V- pins as possible. The part is unity-gain stable, allowing it to be used as a simple buffer without external compensation. For best noise performance, keep feedback resistor values low to minimize thermal noise contributions.
