108 dB, 192 kHz 4-in, 8-out Multi-channel Codec

The CS42888 audio codec provides four 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 64-pin LQFP 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 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 CS42888 is available in a 64-pin LQFP package in Commercial (-10° to +70°) and Automotive (-40° to +105°) grades. The CDB42448 Customer Demonstration board is also available for device evaluation and implementation suggestions. The CS42888 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.
