DESCRIPTION

The PGA4311 is a high−performance, 4-channel audio

volume control designed for professional and high-end

consumer audio systems. Using high performance

operational amplifier stages internal to the PGA4311

yields low noise and distortion, while providing the

capability to drive 600Ω 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 PGA4311

devices.
