General Description

The CS4353 is a complete stereo digital-to-analog system including digital interpolation, fifth-order multi-bit delta-sigma digital-to-analog conversion, digital de-emphasis, analog filtering, and on-chip 2 VRMS line-level driver from a 3.3 V supply.

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 jitter, and a minimal set of external components.

The CS4353 is available in a 24-pin QFN package in Commercial (-40°C to +85°C) grade.
