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.
Up to 200 kHz Sample Rates
Automatic Mode Detection for Sample Rates
between 4 and 2 0 0kHz
Pin Compatible with the CS4341
