GENERAL DESCRIPTION
The CS42432 CODEC provides four multi-bit analog-to-dig-
ital
and
six
multi-bit
digital-to-analog
Delta-sigma
converters. The CODEC is capable of operation with either
differential or single-ended inputs and outputs, in a 52-pin
M
QFP package.
Four
fully differential, or single-ended, inputs are available
on stereo ADC1and ADC2. Digital volume control is provid-
ed for each ADC channel, with selectable overflow
detection.
All six DAC channels provide digital volume control and can
operate with differential or single-ended outputs.
An auxiliary serial input is available for an additional two
channels of PCM data.
The CS42432 is ideal for audio systems requiring wide dy-
namic range, negligible distortion and low noise, such as
A/V receivers, DVD receivers, and automotive audio
systems.
