I am using OP07CP op-amp . V+ and V- are supplied by two 12.2V adapters (which are quite stable!) V1 are supplied using Function Generator
According to what I have learned so far, Vout is equal to V1*2.2/1 = 2.2V1 . Multisim also shows this result . But the problem is that I got the wrong result.
For example :
If V1 is 0 , the output is ~ -0.56
V output is the same for V1=2.5V
What did I miss here ?
