GENERAL DESCRIPTION ：
The ADAU7112 converts stereo pulse density modulation (PDM) bit streams into one pulse code modulation (PCM) output stream. 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 inter-IC serial (I2S) or time domain multiplexed (TDM) format.
The ADAU7112 is specified over a commercial temperature range of −40°C to +85°C. The ADAU7112 is available in a halide-free, 9-ball, 1.26 mm × 1.26 mm, 0.4 mm pitch, wafer level chip scale package (WLCSP).
