The CODEC is capable of operation with ei- ther differential or single-ended inputs and outputs, in a 64-pin LQFP package. Four fully differential, or single-ended, inputs are avail- able on stereo ADC1 and ADC2. Digital volume control is provided for each ADC channel, with selectable over- flow 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 CDB42888 Customer Demonstra- tion board is also available for device evaluation and implementation suggestions. Please refer to “Ordering Information” on page 61 for complete ordering information. 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.
