PCM1802 Audio Stereo ADC Module

The PCM1802 is a high-performance, low-cost, single-chip stereo analog to digital converter with single-ended analog voltage input. The PCM1802 uses a delta-sigma modulator with 64-times or 128‑times oversampling, and includes a digital decimation filter and high-pass filter (HPF), which removes the DC component of the input signal. For various applications, the PCM1802 supports master and slave modes and four data formats in serial interface. The PCM1802 is suitable for a wide variety of cost-sensitive consumer applications where good performance, 5-V analog supply, and 3.3-V digital supply operation is required. The PCM1802 is fabricated using a highly advanced CMOS process and is available in the DB 20-pin SSOP package.
