ADZS-AUDIO-EX3

The ADZS-AUDIO-EX3 is an audio EI3 extender board. It provides a platform for evaluating SigmaDSP stereo 24bit audio codec and MEMs digital microphones, using embedded processor evaluation boards (EZ-Board). This audio EI3 extender board connects with any of the new line of embedded processor EZ-Boards that support the expansion interface 3 (EI3) specification. This new expansion interface gives the user more available signals on the interface connectors and a reduction in size over the previous EI2 specification. The board utilizes the ADAU1761 SigmaDSP stereo, low power, 96KHz, 24bit audio codec. The codec provides line input, line output, auxiliary input and headphone output. The SigmaDSP ADAU1761 connects to the SPORT interface of the EI3 connector (J1). All control and setup communication uses the TWI interface. The audio extender board needs the EZ-KIT Lite/EZ-Board to be powered and does not require power input to the P2 power connector.
