DESCRIPON

The PCM1808-Q1 is high-performance, low-cost, single-chip, stereo analog-to-digital converter with single-ended analog voltage input. The PCM1808-Q1 uses a delta-sigma modulator with 64-times

oversampling and includes a digital decimation filter and high-pass filter that removes the dc component

of the input signal. For various applications, the PCM1808-Q1 supports master and slave mode and two data formats in serial audio interface.
