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.

The ADAU7002 is specified over the commercial temperature range (−40°C to +85°C). It is available in a halide-free, 8-ball, 1.56 mm × 0.76 mm, wafer level chip scale package (WLCSP).

Product Detail

This user guide explains the design and setup of the ADAU7002 evaluation board. This 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.
