I have not used one, but the spec sheet (http://rocky.digikey.com/WebLib/Texas%20Instruments/Web%20data/PGA2311.pdf) is fairly detailed, the communication is via a SPI like interface, so you would use a shiftout/shiftin scheme. If you breadboard it, you may not get as high quality of an output as placing it on a PCB (this is detailed in the document under PCB Layout). Is there a particular question you have regarding the chip?
