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
