DESCRIPTION
PCM1801 is a low cost, single chip stereo analog-to-
digital converter with single-ended analog voltage
inputs. The PCM1801 uses a delta-sigma modulator
with 64x oversampling, a digital decimation filter, and
a serial interface which 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.
