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 se-
lectable 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 de-
vice evaluation and implementation suggestions. See
