Audio Codec 4ADC / 8DAC 24-Bit 52-Pin MQFP T/R

The CS42435 CODEC provides four multi-bit analog-todigital 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. 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. An auxiliary serial input is available for an additional two channels of PCM data. All eight DAC channels provide digital volume control and can operate with differential or single-ended outputs. The CS42435 is available in a 52-pin MQFP package in Commercial (-40°C to +85°C) and Automotive (-40°C to +105°C) grades.
