Part details & applications

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).
