Description
The CS4351 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, volume control, channel mixing, analog filtering,
and on-chip 2 Vrms line level driver. 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 toler-
ance to clock jitter, and a minimal set of external
components.
These features are ideal for cost-sensitive, 2-channel
audio systems including DVD players, A/V receivers,
set-top boxes, digital TVs and VCRs, mini-component
systems, and mixing consoles.
