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. The PCM1808-Q1 supports the power-down and reset function by means of halting the system clock. The PCM1808-Q1 is suitable for wide var...
