DESCRIPTION
The PCM1803 is high-performance, low-cost,
single-chip stereo analog-to-digital converter with
single-ended analog voltage input. The PCM1803
uses a delta-sigma modulator with 64-, 128-times
oversampling, and includes a digital decimation filter
and high-pass filter which removes the DC
component of the input signal. For various
applications, the PCM1803 supports master and
slave modes and four data formats in serial interface. The PCM1803 is suitable for a wide variety of
cost-sensitive consumer applications where good
performance and operation from a 5-V analog supply
and 3.3-V digital supply are required. The PCM1803
is fabricated using a highly advanced CMOS process
and is available in a small 20-pin SSOP package.
