CS4354
5 V Stereo DAC with 2 V
RMS
Ground-centered Output
Features
Advanced Multi-bit Delta-Sigma Modulator
101 dB A-wt Dynamic Range
-86 dB THD+N
Single-ended Ground Centered Analog
Description
The CS4354 is a complete stereo digital-to-analog sys-
tem including digital interpolation, third-order multi-bit
delta-sigma digital-to-analog conversion, digital de-em-
phasis, analog filtering, and on-chip 2 V
RMS
line-level
driver from a 5 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 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 de-
vice evaluation and implementation suggestions.
