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). Applications * Mobile computing * Portable electronics * Consumer electronics * 64× decimation of a stereo pulse density modulation (PDM) bit stream to pulse code modulation (PCM) audio data * Slave I2S or time division multiplexed (TDM) output interface * Configurable TDM slots * I/O supply operation: 1.62 V to 3.6 V * 64× output sample rate PDM clock * 64×/128×/192×/256×/384×/512× output sample rate BCLK * Automatic BCLK ratio detection https://elecena.pl/product/6184558/stereo-pdm-to-is-or-tdm-conversion-ic 2016-07-12 https://elecena.pl/product/6184558/stereo-pdm-to-is-or-tdm-conversion-ic 2018-03-28 https://elecena.pl/product/6184558/stereo-pdm-to-is-or-tdm-conversion-ic 2025-01-19
