Output Stage
composed of two individual channels. The first part of the
output stage interpolates the signal for highly oversampled
D/A conversion and automatically configures itself for the
desired over−sampling rate. Here, the signal is routed to the
SD D/A converter and the direct digital outputs.

analog reconstruction filter to smooth out the effects of
sampling. The reconstruction filter has a cut−off frequency
configurable at 10 or 20 kHz.

by pulse−density modulated outputs that can be used to
directly drive an output transducer without the need for a
separate power amplifier. The output driver has a dedicated
power−supply pin, which allows for separation (through
RC−filtering) between the supply for the analog blocks on
the chip and the supply for the output driver.
The direct digital outputs provide two H−bridges driven
