The EVAL-ADAU1761Z includes both single-ended and differential stereo line-level analog audio inputs as well as a digital audio interface. Single-ended and differential analog outputs are also provided, as well as a stereo capless headphone output.
The USBi provides power and the I2 C communications interface to the evaluation board. A switch allows the ADAU1761 to operate at either 3.3 V or 1.8 V. The SigmaStudio™ programming software is used for all register controls and SigmaDSP® core programming. A header is included for interfacing to stereo digital microphones. GPIO functions, such as push-buttons, LEDs, and switches, can be connected to the GPIO pins of the ADAU1761 for hardware control of the SigmaDSP.
