Description
CS42432 108 dB, 192 kHz 4-In, 6-Out TDM CODEC
FEATURES
Four 24-bit A/D, Six 24-bit D/A Converters ADC Dynamic Range
GENERAL DESCRIPTION
The CS42432 CODEC provides four multi-bit analog-todigital 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 MQFP package.
Four fully differential, or single-ended, inputs are available on stereo ADC1 and ADC2.

DAC Dynamic Range
is provided 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 available in a 52-pin MQFP package in Commercial (-10° to +70°) and Automotive (-40° to +105°) grades.
The CDB42432 Customer Demonstration board is also available for device evaluation and implementation suggestions.
Please refer to “Ordering Information” on page 58 for complete ordering information.
The CS42432 is ideal for audio systems requiring wide dynamic range, negligible distortion and low noise, such as A/V receivers, DVD receivers, and automotive audio systems.
