    Overview

    The EVAL-ADAU7002Z evaluation board provides full access to all inputs and outputs on the ADAU7002. This evaluation board can be powered by a single 3.8 V to 6 V supply or by VDD of the pulse density modulation (PDM) input. The PC board is a 4-layer design, with a single ground plane and a single power plane on the inner layers. The board contains connectors for external microphones and headers for PDM input and I2S output.

    The ADAU7002 converts a stereo PDM bit stream into a PCM output. The source for the PDM data can be two microphones or other PDM sources. The PCM audio data is output on a serial audio interface port in either I2S or TDM format.

    Key Applications: Mobile computing, Portable electronics, Consumer electronics.
