Long story short. Started teaching myself electronics 4 months ago. My first circuit was an LM386 mini amp. Had lots of questions but slowly answered them by trial and error. Moved on with simple FM transmitter and got it to work fairly. Eventually decided to build a TDA2050 amp. I googled for answers but found nothing useful. Now I hope the awesome people on this forum can help. Thanks in advance.
Question #1: How do you measure Output Watts of an Amp Circuit? I tried just hooking up my Meter to my 12V DC power supply and when I cranked it as hard as I could go without distortion, it would only draw 0.35A. That only equals ~4W but the datasheet claims 35W RMS into 4ohms with 18V-22V Power Supply. I grabbed my Laptop's 19V Supply and only got about max 0.4A. Thats still only ~8W. Anyone know what I'm doing wrong? Also the datasheet claims Max of 5A current output and I'm no where near that.
Question #2: I used the Single Supply Circuit on the datasheet instead of the Split Power Supply Circuit because I didn't know what they meant by +Vs and -Vs. Does +Vs mean positive battery terminal and -Vs is negative battery terminal? It can't be that easy can it?
Question #3: Will the Split Power Supply Circuit sound better than the Single Supply Circuit? Any difference?
Question #4: The circuit didn't specify the voltages of capacitors or the wattage of resistors. Does it matter what Caps I use and what watt rating I use for resistors?
Again I would appreciate all help and I will always help anyone else in need when I learn more about this awesome world of electronics.
