24位立体声数模转换技术CS4354主要特性及应用
The CS4354 is a complete stereo digital-to-analog system including digital interpolation, third-order multi-bit delta-sigma digital-to-analog conversion, digital de-emphasis, analog filtering, and on-chip 2 VRMS line-level driver from a 5 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 CS4354 is available in a 14-pin SOIC package in Commercial (-40°C to +85°C) grade. The CDB4354 Customer Demonstration Board is also available for device evaluation and implementation suggestions.
These features are ideal for cost-sensitive, 2-channel audio systems including video game consoles, Blu-Ray Disc® and DVD players, set-top boxes, digital TVs, and DAB/DMB devices.
