CS4244 Datasheet - Cirrus Logic

General Description
   The CS4244 provides four multibit analog-to-digital and four multi-bit digital-to-analog - 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.
