Description

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 CS42438 are available on stereo ADC1, ADC2, and ADC3. When operating in Singleended 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 of CS42438 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 ideal for audio systems requiring wide dynamic range, negligible distortion and low noise, such as A/V receivers, DVD receivers, and automotive audio systems.
