ADI EVAL-ADAU1761Z

The EVAL-ADAU1761Z evaluation board features single-ended and differential stereo line-level analog audio inputs along with a digital audio interface, and also provides single-ended and differential analog outputs as well as a stereo capless headphone output. The USBi supplies power and an I²C communication interface to the evaluation board, with a switch allowing the ADAU1761 to operate at either 3.3V or 1.8V. All register control and SigmaDSP core programming are performed using the SigmaStudio programming software. The evaluation board also includes an interface for connecting stereo digital microphones, and supports connecting GPIO functions — such as buttons, LEDs, and switches — to the GPIO pins of the ADAU1761 for hardware control of the SigmaDSP.
