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.
