ADAU7002 - Stereo PDM-to-I2S or TDM Conversion

Description

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.

Features

  • 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 Output sample rate: 4 kHz to 96 kHz Automatic PDM CLK drive at 64× the sample rate Automatic power down with BCLK removal 0.67 mA operating current a.
