Description
The CS4340 is a complete stereo digital-to-analog system
including digital interpolation, fourth-order delta-sigma dig-
I
ital-to-analog conversion, digital de-emphasis and
switched capacitor analog filtering. The advantages of this
architecture include: ideal differential linearity, no distor-
tion mechanisms due to resistor matching errors, no
linearity drift over time and temperature and a high toler-
ance to clock jitter.
The CS4340 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
CS4340 are ideal for DVD players, CD players, set-top box
and automotive systems.
