EVAL-ADAU7118Z

EVAL-ADAU7118Z is an evaluation board to evaluate the ADAU7118 8-channel PDM to I2S/TDM converter. The ADAU7118 is a converter that takes in a Pulse Density Modulation signal from a MEMS microphone and converts it into an I2S (Inter IC Serial bus) signal or a TDM serial communication bus. The EVALADAU7118Z can be set to operate in hardware mode or configured to control the ADAU7118 via I2C communication interface. An I2S serial interface is accessible via header pins spaced at 0.1inches. Pulse density modulation (PDM) data and the clock interface are available on these headers. The evaluation board can be connected to an external 5V DC power supply and ground or can be powered from the USB interface. On-board regulators derive supplies of 3.3V, 1.8V and 1.2V. The evaluation board can be configured to operate fully from external power supplies bypassing the on-board regulators. Current measurements of the ADAU7118 are made with the supplied header pins.
