I2C-bus controlled 4
45 W best efficiency amplifier
7.3.3 Start-up and shut-down engine start and best efficiency control
start-up and shut-down of the amplifier is in BTL mode, even when best efficiency
mode is selected
best efficiency mode can be enabled or disabled via I2C-bus commands
a. Voltage waveform locations
b. Voltage waveforms
