Hello everyone.
I want to build a stereo amp and I have seen the datasheet of TDA1554. So I want to ask about the quality of the amp. Is the amplifier powerful enough for a room?
And also, I am trying to make a power supply to drive it at approx 12v. So which transformer should I use?

Hi,
TDA1554 have high distortion at max levels, so you could use better chip..
To calculate AC voltage for trafo use this calculation: DC voltage / 1.414 + voltage drop on diodes, it is 12/1.41+~1,5=10 Volts AC

I have not used this particular TDA but my experience with the TDAs tell me they very low power high distortion chips. They are generally used in portable and low power stereos. Would be enough for your room if driving a good pair of speakers.
Hmmm
I think this chip will be satisfactory. Because I already have TDA2004 amp and its enough for me. Comparing to it, the TDA1554 is powerful, right?
and also this amp is just for a project purpose, it is not meant to be used in a very sophisticated system, so this chip will work for me.
and about transformer, if I use a 12-0 transformer, then I should get, approx 15-16v, right?
also should I use a 5A transformer? and will IN4007 diodes work in bridge rectifier? or I should use more current capacity diodes?
