TDA7265 Current Rating

[Sh00pus]

I had posted before about a 15W Chip amp, but I'm thinking about getting the TDA7265 with a bit more power.

Does anyone know how much current this chip will draw at around +/- 20V? I see the output peak current is 4A on the data sheet, is that also how much it would draw? Would a 2A transformer work?

I would guesstimate about a 200VA transformer.

Class AB, 100w+100w + 60w (heat) + 60 watt (heat)

I thought it was a 20W amplifier. So wouldn't it be 20W + 20W + 23W(heat)+23W(heat)?

The spec says it is 100w + 100w.
If you are going to make it 20w then you don't need such a big transformer.
