8.4.6.2 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 Low Idle Current mode
the outputs operate at ~17% modulation during idle conditions. When an audio signal is applied, one output
decreases and one increases. The decreasing output signal rails to GND. At this 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.

8.4.6.3 Hybrid Modulation
Hybrid Modulation is designed for minimized power loss without compromising the THD+N performance, and
is optimized for battery-powered applications. With Hybrid modulation, TAS5828M detects the input signal level
and adjust PWM duty cycle dynamically based on PVDD. Hybrid modulation achieves ultra low idle current and
maintains the same audio performance level as the BD Modulation.
