I can see the various output power with different VDD from Figure 33. Output Power vs Load Resistance.
but i need to estimate the outpower power level at 3.3V to insure output power from TPA2012 is not bigger than 0.7W speaker.
my speaker has 0.7watt rating thus i want to feed less than 0.7W to prevent blowing speaker.
where i can find the equation to calculate?
