Description
The CS4340A 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 CS4340A 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 CS4340, as described in section 3.1.
These features are ideal for DVD audio players.
