DESCRIPTION
The PCM1801 is a low-cost, single-chip stereo
analog-to-digital converter (ADC) with single-ended
analog voltage inputs. The PCM1801 uses a
delta-sigma modulator with 64 times oversampling, a
digital decimation filter, and a serial interface that supports slave mode operation and two data formats.
The PCM1801 is suitable for a wide variety of
cost-sensitive consumer applications where good
performance is required.
