Description
The CS4341 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 CS4341 accepts data at audio sample rates from
2 kHz to 100 kHz, consumes very little power and oper-
ates over a wide power supply range. These features are
ideal for DVD, A/V receiver and set-top box systems.
