Description

The PGA2320 is a high-performance, stereo audio volume control designed for professional and high-end consumer audio systems. The ability to operate from ±15V analog power supplies enables the PGA2320 to process input signals with large voltage swings, thereby preserving the dynamic range available in the overall signal path. Using high performance operational amplifier stages internal to the PGA2320 yields low noise and distortion, while providing the capability to drive 600 loads directly without buffering. The three-wire serial control interface allows for connection to a wide variety of host controllers, in addition to support for daisy-chaining of multiple PGA2320 devices.
