DESCRIPTION
The PCM1803A is high-performance, low-cost,
single-chip stereo analog-to-digital converter with
single-ended analog voltage input. The PCM1803A
uses a delta-sigma modulator with 64- and 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 PCM1803A supports master and
slave modes and four data formats in serial interface.
The PCM1803A 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
PCM1803A is fabricated using a highly advanced
CMOS process and is available in a small 20-pin
SSOP package.
