MODSEL = GND: BD-modulation This is a modulation scheme that allows operation without the classic LC reconstruction filter when the amp is driving an inductive load with short speaker wires. Each output is switching from 0 volts to the supply voltage.
PAGE 21
TPA3116D2 TPA3118D2 TPA3130D2 www.ti.com SLOS708C – APRIL 2012 – REVISED NOVEMBER 2013 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.

TPA3116D2 TPA3118D2 TPA3130D2 SLOS708C – APRIL 2012 – REVISED NOVEMBER 2013 www.ti.com EFFICIENCY: LC FILTER REQUIRED WITH THE TRADITIONAL CLASS-D MODULATION SCHEME The main reason that the traditional class-D amplifier-based on AD modulation needs an output filter is that the switching waveform results in maximum current flow. This causes more loss in the load, which causes lower efficiency.

The TPA3116D2 EVM passes FCC class-B specifications under these conditions using twisted speaker wires. The size and type of ferrite bead can be selected to meet application requirements.

The LC filter should be placed close to the outputs. The capacitors used in both the ferrite and LC filters should be grounded.
