Description
The CS4391A is a complete stereo digital-to-analog sys-
tem including digital interpolation, fourth-order delta-
sigma digital-to-analog conversion, digital de-emphasis,
volume 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 CS4391A accepts PCM data at sample rates from
4 kHz to 192 kHz, DSD audio data, consumes very little
power and operates over a wide power supply range.
These features are ideal for DVD, A/V receivers, CD and
set-top box systems.
