资料介绍

FEATURES: 2 channels of PDM audio inputs from digital microphones 64× decimation ratio of PDM to PCM audio data 24-bit resolution to support high sound pressure level (SPL) microphones 126 dB A-weighted SNR 4 kHz to 96 kHz output sampling rate Bit clock rates of 64×, 128×, 192×, 256×, 384×, or 512× the output sampling rate Automatic PDM clock generation Automatic power-down when BCLK is removed 0.36 mA DVDD operating current at 48 kHz sampling rate and 1.8 V supply Slave I2S or TDM output interface Up to TDM-16 supported Configurable TDM slots I/O supply voltage from 1.70 V to 3.63 V DVDD core supply voltage from 1.10 V to 1.98 V 4 μA typical DVDD shutdown current 9-ball, 1.26 mm × 1.26 mm, 0.4 mm pitch WLCSP Power-on reset APPLICATIONS: Mobile computing Portable electronics Consumer electronics Professional electronics 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).
