APPLICATION INFORMATION
power dissipation in amplifier

where:
+ Ȁ ICC Amplifier s quiescent current
+ IOM Peak-output-signalling current from amplifier
+ PO Output power consumed by coupling network and load
The power dissipated in the amplifier is minimized if the amplifier’s peak output current, I_OM, is minimized. Since
the output power consumed by the coupling and load is a function of current and voltage ( P_O ≈ I_O × V_O ), the
amplifier’s peak output current can be minimized by maximizing the amplifier’s output voltage swing.
