The CS4349 is a complete stereo digital-to-analog system including digital interpolation, 5th-order multi-bit delta-
sigma digital-to-analog conversion, digital de-emphasis, volume control, channel mixing, and analog filtering. The
advantages of this architecture include ideal linearity, no distortion mechanisms due to resistor matching errors, no
linearity drift over time and temperature, tolerance to clock jitter, and a minimal set of external components.
The CS4349 supports all standard digital audio interface formats, including TDM.
The CS4349 is available in a 24-pin TSSOP package in both Commercial (-40° to +85°C) and Automotive grades
(-40° to +105°C). The CDB4349 Customer Demonstration board is also available for device evaluation and imple-
mentation suggestions. “Ordering Information” on page 39 provides complete ordering information.
These features are ideal for cost-sensitive, two-channel audio systems, including DVD players and recorders, set-
top boxes, digital TVs, mini-component systems, musical instruments and automotive audio systems.
