DescriptionThe PCM1803A device is high-performance, low-
cost, single-chip stereo analog-to-digital converter
with single-ended analog voltage input. The
PCM1803A usesa delta-sigma modulator with 64-
and 128-times oversampling, and includesa digital
decimation filter and high-pass filter, which removes
the DC componentof the input signal. For various
applications, the PCM1803A supports master and
slave modes and four data formatsin serial interface.
The PCM1803Ais suitable fora wide varietyof cost-
sensitive consumer applications where good
performance and operation froma 5-V analog supply
and 3.3-V digital supply are required. The PCM1803A fabricated usinga highly-advanced CMOS process
andis availableina small 20-pin SSOP package.
