CS4354-CSZR

The CS4354 is a complete stereo digital-to-analog systemincluding digital interpolation, third-order multi-bitdelta–sigma digital-to-analog conversion, digital de-emphasis,analog filtering, and on-chip 2 VRMS line-leveldriver from a 5 V supply.The advantages of this architecture include ideal differentiallinearity, no distortion mechanisms due to resistormatching errors, no linearity drift over time and temperature,high tolerance to clock jitter, and a minimal set ofexternal components.These features are ideal for cost-sensitive, two-channelaudio systems including video game consoles, Blu-RayDisc and DVD players, set-top boxes, digital TVs, andDAB/DMB devices.The CS4354 is available in a 14-pin SOIC package inCommercial (–40°C to +85°C) grade. The CDB4354Customer Demonstration Board is also available for deviceevaluation and implementation suggestions.
