GENERAL DESCRIPTION:
The ADAU7118 converts four stereo pulse density modulation (PDM) itstreams into one pulse code modulation (PCM) output stream. The source for the PDM data can be eight 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 ADAU7118 is specified over the commercial temperature range (−40°C to +85°C). The ADAU7118 is available in a 16-lead, 3 mm × 3 mm, 0.40 mm pitch, lead frame chip scale package (LFCSP).
