hi,
Is it possible to realize a adder circuit with an single supply operational?
Can I to adder the signals on the non inverting input?
Anyone has an idea?
thanks.
If the voltages come from stiff sources you can combine them with two resistors to a floating point. The output will be a scaled sum of the two. Then put that point ot the noninverting input of an op amp in the noninverting configruation.
