The CS42438 CODEC provides six multi-bit analog-to-digitaland eight multi-bit digital-to-analog Delta-sigmaconverters. The CODEC is capable of operation with eitherdifferential or single-ended inputs and outputs, in a 52-pinMQFP package.

Six fully differential, or single-ended, inputs are available onstereo ADC1, ADC2, and ADC3. When operating in SingleendedMode, an internal MUX before ADC3 allows selectionfrom up to four single-ended inputs. Digital volumecontrol is provided for each ADC channel, with selectableoverflow detection.

All eight DAC channels provide digital volume control andcan operate with differential or single-ended outputs.An auxiliary serial input is available for an additional twochannels of PCM data.

The CS42438 is ideal for audio systems requiring wide dynamicrange, negligible distortion and low noise, such asA/V receivers, DVD receivers, and automotive audiosystems.
