DESCRIPTION
PCM1800 is a low cost, single chip stereo analog-to-
digital converter with single-ended analog voltage
inputs. The PCM1800 uses a delta-sigma modulator
with 64X oversampling, including a digital decima-
tion filter and serial interface which supports both
Master and Slave Modes and four data formats.
PCM1800 is suitable for a wide variety of cost-sensi-
tive consumer applications where high performance is
required.
PCM1800 is fabricated on a highly advanced CMOS
process.
