ADAU7002ACBZ-RL
立体声PDM至I2S或TDM转换IC Stereo PDM-to-I2S or TDM Conversion IC
Product Details
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.
