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
and switched capacitor 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 temperature and a high
tolerance to clock jitter.
The CS4341 accepts data at audio sample rates from
4 kHz to 100 kHz, consumes very little power, and oper-
ates over a wide power supply range. The features of
the CS4341 are ideal for DVD players, CD players, set-
top box and automotive systems.
