GENERAL DESCRIPTION
The CS42438 CODEC provides six multi-bit analog-to-digi-
tal and eight 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.
Six fully differential, or single-ended, inputs are available on
stereo ADC1, ADC2, and ADC3. When operating in Single-
ended Mode, an internal MUX before ADC3 allows selec-
tion from up to four single-ended inputs. Digital volume
control is provided for each ADC channel, with selectable
overflow detection.
All eight 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 CS42438 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.
