The advantages of this architecture include ideal differential linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and temperature, high tolerance to clock jit- ter, and a minimal set of external components. The CS4350 supports all standard digital audio interface formats, including TDM. The CS4350 is available in a 24-pin QFN package in Commercial grade (-40 to +85C). The CS4350 is available in a 24-pin TSSOP package in both Commercial (-40 to +85C) and Automotive grades (-40 to +105C). The CDB4350 Customer Demonstration board is also available for device evaluation and implementation sugges- tions. Please refer to Ordering Information on page 40 for 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, mixing consoles and automotive audio systems. 2 DS691F4
