This user guide describes the design and setup of the EVALADAU7112Z evaluation board, which can be configured to operate in several different hardware modes. An I2S/time division multiplexing (TDM) serial interface is accessible via header pins spaced at 0.1 inches. Pulse density modulation (PDM) data and the clock interface are available on these headers.
The evaluation board can be powered in several ways:
- External 5 V dc power supply and ground using the J14 header
- External 5 V power supply (not included) using the J8 power connector
- Directly powered using external power supplies that bypass the on-board regulators
On-board regulators derive supplies of 3.3 V, 1.8 V, and 1.2 V. Current measurements of the ADAU7112 can be performed with the supplied header pins.
The evaluation board allows demonstration and performance testing of the features of the ADAU7112.
For full details, see the ADAU7112 data sheet, which must be consulted in conjunction with this user guide when using the evaluation board.
