Description

The PGA4311U is a 4-channel high-performance 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 600R 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. It is fabricated in a sub-micron CMOS process. The heart of this controller is a resistor network, an analog switch array and a high-performance op-amp stage. The switches are used to select taps in the resistor network that, in turn, determine the gain of the amplifier stage. Switch selections are programmed using a serial control port. The serial port allows connection to a wide variety of host controllers.
Four independent audio channels
Serial control interface
Zero crossing detection
Mute function
Low interchannel crosstalk
