PCM1802
Description
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.
