Hi,
I tried an opamp (TL082) as a buffer stage (output pin connected to negative input ). When I gave +15 and -15 supply and varied the positive input from 0 to 10 V, the output was not going above 9.4V. But when I connected GND to - supply point (instead of -15V) I got 10V output for 10V input. Why does this happen?
