Hi, I’m not sure if the pHAT can deliver the 2Ws to the speaker included in the kit.
I know the amplifier is 3W (3.2 acording the MAX98357A datasheet) and the speaker is 2W.
But the high power limit only can reached with 4ohm speaker (the included is 8ohm).
The datasheet informs for example, that at 5v (page 11, graph 1) this gets 1.75W (already with 10% thd).
The test configuration uses GAIN_SLOT at 12db. The max is 15db configuration. So I dont know if the pHAT uses the gain_slot at 15db making any difference.
Acording my questions i ask: the Speaker pHAT can really drive the original speaker at 2W (even with higher THD)?
