Output Stage
The analog audio output and the digital output are
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 oversampling rate. Here, the signal is routed to the
SD D/A converter and the direct digital outputs.
The D/A converter translates the signal into a
highfidelity analog signal and passes it into a third order
analog reconstruction filter to smooth out the effects of
sampling. The reconstruction filter has a cutoff frequency
configurable at 10 or 20 kHz.
From the reconstruction filter, the signal passes through
the programmable output attenuator, which can adjust the
signal for various line level outputs or mute the signal
altogether. The attenuator can be configured to a value in the
interval 12 to 30 dB (3 dB steps) or it can be bypassed.
The direct digital outputs provide two Hbridges driven
by pulsedensity 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
powersupply pin, which allows for separation (through
RCfiltering) between the supply for the analog blocks on
the chip and the supply for the output driver.
The output stage is shown in Figure 8.
