I am trying to read this datasheet (NXP TDF8546 Class AB Power Amplifier). On page 12, the power calculations are mentioned as
Po(max): RL = 4 Ohm, Vp = 14.4V, Vi = 2 V RMS Square wave
As far as I know, while calculating power calculations for any power amplifiers, engineers typically consider the sine wave. The reason I know is, its fundamental signal, and harsh input for power amplifier.
Why NXP considered square wave instead of sine wave in this datasheet?
