DESCRIPTION
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 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 PGA2311
devices.
