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.
