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.
