Hi everyone,
I have an IC OPA227.
At pin 2 i insert from a function generator a sinus signal with peak amplitude 5 volts,50Hz. In between there is a resistance of 1.3kOhm.
Pin 3 and pin 4 are grounded.
At pin 7 i put 5V dc. The not mentioned pins are NC.
When i measure my output(pin6) i have zero when sinus signal is positive and 5 volts when sinus is negative.
Thats all good i think so far.
When i change the connection between pin2 and pin3 alternately, instead of having the opposite result i have 5 volts when the signal is positive and instead of having zero(in my output) when the signal is negative, in some part i have positive voltage again........
So, i think you got my point of what i am trying to do..Any ideas?!
Thanks..
