MODSEL = HIGH: 1SPW-modulation
The 1SPW mode alters the normal modulation scheme in order to achieve higher efficiency with a slight penalty
in THD degradation and more attention required in the output filter selection. In 1SPW mode the outputs operate
at ~15% modulation during idle conditions. When an audio signal is applied one output will decrease and one will
increase. The decreasing output signal will quickly rail to GND at which point all the audio modulation takes place
through the rising output. The result is that only one output is switching during a majority of the audio cycle.
Efficiency is improved in this mode due to the reduction of switching losses. The THD penalty in 1SPW mode is
minimized by the high performance feedback loop. The resulting audio signal at each half output has a
discontinuity each time the output rails to GND. This can cause ringing in the audio reconstruction filter unless
care is taken in the selection of the filter components and type of filter used.
