consumer  
audio  
systems.  
Using  
LOW INTERCHANNEL CROSSTALK:  
–130dBFS  
high-performance operational amplifier stages internal  
to the PGA8311 yields low noise and distortion, while  
providing the capability to drive 600loads 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 PGA8311 devices.
