Can this be run from a 5 volt supply? I need to amplify uV signals to use a dynamic mic in place of an electret mic.
I would like help on how to feed my preamp, I have:
- toroidal transformer 25-0-25 (2.41A)
- tda7293 amplifier
I’d like to feed the preamp (12v; 0.01a) and a fan (12v; 0.18a) with the same transformer straightening the current before the connections. What connections and what kind of resistances should I use? Thanks in advance
