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.
