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 +85°C) and Commercial (0°C to
+70°C) temperature grades. The CDB4244 Customer
Demonstration Board is also available for device evalu-
ation and implementation suggestions. See “Ordering
Information” on page 64 for complete details.
