Description

The CS4353 is a complete stereo digital-to-analog sys-

tem including digital interpolation, fifth-order multi-bit

delta-sigma digital-to-analog conversion, digital de-em-

phasis, analog filtering, and on-chip 2 V

driver from a 3.3 V supply.

The advantages of this architecture include ideal differ-

ential linearity, no distortion mechanisms due to resistor

matching errors, no linearity drift over time and temper-

ature, high tolerance to clock jitter, and a minimal set of

external components.

The CS4353 is available in a 24-pin QFN package in

both Automotive (-40°C to +105°C) and Commercial

(-40°C to +85°C) grades. The CDB4353 Customer

Demonstration Board is also available for device evalu-

ation and implementation suggestions. Please see

“Ordering Information” on page 26

These features are ideal for cost-sensitive, 2-channel

audio systems including video game consoles, DVD

players and recorders, A/V receivers, set-top boxes,

digital TVs, mini-component systems, and mixing

consoles.
