What to be aware of when considering power supply for a 100 watt amplifier? Answered
I have a TDA7294 IC and want to know what kind of power supply should I build for it so that it can work safely. I heard that even though it works on 12V DC there are other things to take into consideration when choosing the tansformer and designing the AC to DC converter, like amperes and watts.
My current set up is the following: a transformer (input: 220V AC; output: AC2*12V) a rectifier and a 35V, 2200 uF capacitor. I know this is very cheap and low quality but can you explain why in principle wouldn't an amplifier like the above work properly with such power supply?
How do I calculate the ideal values of these factors for a 100 watt amplifier?
