Copyright © Cirrus Logic, Inc. 2005 (All Rights Reserved) Cirrus Logic, Inc. http://www.cirrus.com FEATURES Four 24-bit A/D, Six 24-bit D/A Converters ADC Dynamic Range – 105 dB Differential – 102 dB Single-ended DAC Dynamic Range – 108 dB Differential – 105 dB Single-ended ADC/DAC THD+N – -98 dB Differential – -95 dB Single-ended Compatible with Industry-standard Time Division Multiplexed (TDM) Serial Interface DAC Sampling Rates up to 192 kHz ADC Sampling Rates up to 96 kHz Programmable ADC High-pass Filter for DC Offset Calibration Logarithmic Digital Volume Control Hardware Mode or Software I²C & SPI ™ Supports Logic Levels Between 5 V and 1.8 V 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.
