The Texas Instruments OPA2134UA is a dual-channel SoundPlus audio operational amplifier built on a FET input stage. It operates from ±2.5 V to ±18 V supplies and is optimised for low noise and low distortion, which makes it a dependable building block for professional audio paths, active filters and high-quality preamplifier stages. Supplied in an 8-lead SOIC package, it combines wide bandwidth with a high slew rate so that fast audio transients remain clean.
