I had a voltage divider which was suppose to drop down a voltage to 3V connected to the input of an OpAmp. And it worked fine. But I noticed, when Ipowered off the OpAmp, that 3V dropped down to 1.7V, I wasn't expecting this. What do you think would cause this? My guess is some input protection circuitry, maybe a couple diode drops or something?
