Application information
41/55
and its value is:
Note:
This maximum value depends only on the power supply voltage and load values.
The efficiency is the ratio between the output power and the power supply:
The maximum theoretical value is reached when VPEAK = VCC/2, so
4.3.2
Phantom ground output configuration (modes 3, 4):
The average current delivered by the supply voltage is:
Figure 125. Current delivered by supply voltage in a phantom ground output
configuration
The power delivered by the supply voltage is:
Then, the power dissipation by each amplifier is
and the maximum value is obtained when:
and its value is:
Note:
This maximum value depends only on the power supply voltage and load values.
