I have an opamp circuit with +/-12V supplies and a desired output range of 0-5V.
It is possible if a user plugs the wrong thing into the input of this circuit for the Opamp to put out up to 7.5V.
If wanted to make sure that the Opamp output never goes beyond 5V would I connect the output of the opamp to current limiting resistor and then to the anode of of a schottky diode and the cathode of the schottky is connected to a 5V reference voltage?
I think this is called clamping.
At the same point I can also connect another shottky to ground so that the voltage never goes below zero as well.
