General Description

 2 Vrms full-scale output into 3-k AC load

 Rail-to-rail operation

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.

ADC Features

 Advanced multibit delta-sigma modulator

 24-bit resolution

 Differential inputs

 -105 dB dynamic range (A-weighted)

 -88 dB THD+N

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.
