Hi
I need to generate a DC signal which can have a positive or a negative voltage for example any value from -15V to +15V and can reach 1A of current, I use an amplifier that can provide 1A of current to generate that signal so the amplifier need to be supplied by a positive and negative voltages for example Vdd=+20V and Vss=-20V so my question is how much current I need from the positive and the negative supplies? I use a generator to get the +20V which can give me as much current as I need but for the -20V I am using a switching regulator the probleme is that the regulator can give me only 100mA of current and I don't know now if I need more or just I can seek the current from the generator, I hope the question was clear, thank you.
