The CS4244 provides four multibit analog-to-digital and four multi-bit digital-to-analog Delta Sigma converters and is compatible with differential inputs and either differential or single-ended outputs. Digital volume control, noise gating, and muting is provided for each DAC path. A selectable high-pass filter is provided for the 4 ADC inputs. The CS4244 supports master and slave modes and TDM, left-justified, and I²S modes. This product is available in a 40-pin QFN package in Automotive (-40 °C to +105 °C) and Commercial (-40 °C to +85 °C) temperature grades. The CDB4244 Customer Demonstration Board is also available for device evaluation and implementation suggestions.
