Hello.
Can you sum two voltages with opposite polarity with a op-amp summer circuit?
I have a 0-3,3V signal that is going to be amplified through a op-amp to 0-33V, but!
When the signal is 0V the op-amp should output ~ -3V, could I use a op-amp summer with the 0-3,3V signal and a -0,3V to end up with -3V to +30V?
Giving that the op-amp is being supplied with say +35V/-5V.
