PGA2311 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.
The heart of the PGA2311 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 PGA2311 includes a zero crossing detection function that can provide for noise-free level transitions.
The concept is to change gain settings on a zero crossing of the input signal, thus minimizing audible glitches .The zero crossing detection takes effect with a change in gain setting for a corresponding channel.
The new gain setting will not be implemented until either positive slope zero crossing is detected or a time-out period of 16ms has elapsed. In the case of a time-out, the new gain setting takes effect with no attempt to minimize audible artifacts. This board features a fully independent signal and power ground .
