Product Introduction

Overview

The PGA2310UA, produced by Texas Instruments, is a high-performance stereo audio volume control designed for professional and high-end consumer audio systems. It operates from ±15-V analog power supplies, enabling it to process input signals with large voltage swings and preserve the dynamic range in the overall signal path. The device utilizes high-performance operational amplifier stages, resulting in low noise and distortion, and can drive 600-Ω loads directly without buffering. It features a three-wire serial control interface, supporting connection to various host controllers and daisy-chaining of multiple PGA2310 devices.
