Description
The CS4392 is a complete stereo digital-to-analog sys-
tem including digital interpolation, fifth-order delta-sigma
20 AMUTEC
digital-to-analog conversion, digital de-emphasis, vol-

AOUTA-
ume control, channel mixing and analog filtering. The
18
AOUTA+
advantages of this architecture include: ideal differential
17
VA
linearity, no distortion mechanisms due to resistor
16 AGND
matching errors, no linearity drift over time and tempera-
ture, and a high tolerance to clock jitter.

The CS4392 accepts PCM data at sample rates from
13 BMUTEC
4 kHz to 192 kHz, DSD audio data, has selectable digital
filters, and consumes very little power. These features
12
CMOUT
are ideal for DVD, SACD players, A/V receivers, CD and

FILT+
set-top box systems. The CS4392 is pin and register
compatible with the CS4391, making easy performance
upgrades possible.
