CS4352
192 kHz Stereo DAC with 2 Vrms Line Out
Features
Description
Multi-bit Delta-Sigma Modulator
24-Bit Resolution
The CS4352 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 Vrms line-level
driver. The advantages of this architecture include ideal
differential linearity, no distortion mechanisms due to re-
sistor matching errors, no linearity drift over time and
temperature, high tolerance to clock jitter, and a minimal
set of external components.
