The CS42448 CODEC provides six multi-bit analog-todigitaland eight multi-bit digital-to-analog delta-sigmaconverters. The CODEC is capable of operation with eitherdifferential or single-ended inputs and outputs, in a64-pin LQFP package.Six fully differential, or single-ended, inputs are availableon stereo ADC1, ADC2, and ADC3. Whenoperating in Single-Ended Mode, an internal MUX beforeADC3 allows selection from up to four single-endedinputs. Digital volume control is provided for each ADCchannel, with selectable overflow detection.All eight DAC channels provide digital volume controland can operate with differential or single-endedoutputs.An auxiliary serial input is available for an additional twochannels of PCM data.The CS42448 is available in a 64-pin LQFP package inCommercial (-10°C to +70°C) and Automotive (-40°C to+105°C) grades. The CDB42448 Customer Demonstrationboard is also available for device evaluation andimplementation suggestions.The CS42448 is ideal for audio systems requiring widedynamic range, negligible distortion and low noise, suchas A/V receivers, DVD receivers, and automotive audiosystems.
