CS42438

CS42438 108 dB, 192 kHz 6-In, 8-Out TDM CODEC FEATURES GENERAL DESCRIPTION  Six 24-bit A/D, Eight 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™ and SPI™  Supports Logic Levels Between 5 V and 1.8 V The CS42438 CODEC provides six multi-bit analog-to-digital 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 MQFP 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 selection 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 available in a 52-pin MQFP package in Commercial (-10°C to +70°C) and Automotive (-40°...
