Application information
25/32
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:
4.4.2
Phantom ground configuration
The average current delivered by the power supply voltage is:
Figure 81.
Current delivered by power supply voltage in phantom ground
configuration
The power delivered by the power supply voltage is:
Therefore, 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 power supply voltage and load values.
