3 Description
The PGA2311 device is a high-performance, stereo
audio volume control designed for professional and
high-end consumer audio systems. The PGA2311
uses an internal high-performance operational
amplifier to yield low noise and distortion. The
PGA2311 also provides the capability to drive 660-Ω
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.
