Description
The CS4392 is a complete stereo digital-to-analog sys-
tem including digital interpolation, fifth-order delta-sigma
digital-to-analog conversion, digital de-emphasis, vol-
ume control, channel mixing and analog filtering. The
advantages of this architecture include: ideal differential
linearity, no distortion mechanisms due to resistor
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
4 kHz to 192 kHz, DSD audio data, has selectable digital
filters, and consumes very little power. These features
are ideal for DVD, SACD players, A/V receivers, CD and
set-top box systems. The CS4392 is pin and register
compatible with the CS4391, making easy performance
upgrades possible.
