Audio Codec 4ADC / 4DAC 24-Bit 40-Pin QFN EP T/R

The CS4244 provides four multibit analog-to-digital andfour multi-bit digital-to-analog D-S converters and iscompatible with differential inputs and either differentialor single-ended outputs. Digital volume control, noisegating, and muting is provided for each DAC path. A selectablehigh-pass filter is provided for the 4 ADC inputs.The CS4244 supports master and slave modes andTDM, left-justified, and I²S modes.This product is available in a 40-pin QFN package inAutomotive (-40°C to +85°C) and Commercial (0°C to+70°C) temperature grades. The CDB4244 CustomerDemonstration Board is also available for device evaluationand implementation suggestions.
