Description

The CS4341A 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 CS4341A accepts data at all standard audio sample

rates up to 192 kHz, consumes very little power, oper-

ates over a wide power supply range and is pin

compatible with the CS4341, as described in section 3.1.

These features are ideal for DVD audio players.
