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 +85C) and Automotive grades (-40 to +105C). 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. 2 DS782F2
