The PGA2311 is a high–performance, stereo audio volume control designed for professional and high-end consumer audio systems. Using high performance operational amplifier stages internal to the PGA2311 yields low noise and distortion, while providing the capability to drive 600 loads directly without buffering. The 3-wire serial control interface allows for connection to a wide variety of host controllers, in addition to support for daisy-chaining of multiple PGA2311 devices.
