Introduction

The CS42432 CODEC provides four multi-bit analog-to-digital 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. Digital volume control 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°C to +70°C) and Automotive (-40°C to +105°C) grades. 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.
