I setup an op amp (TL081CP) in non-inverting amplifier configuration.
My pin voltages:
VCC- = 0 V
VCC+ = 15 V
IN+ = Varied between 0 V and 15 V with a potentiometer. (X-axis)
IN- = Connected to 0 V and OUT with 1.5 kOhm resistors.
OUT = Measured (Y-axis)
Here is what my circuit roughly looks like:
Here is a picture where I vary IN+ voltage on X-axis and OUT is on Y-axis:
The circuit works correctly for the most part but when IN- is near 0 V, OUT jumps to near 15 V. Is this typical behavior for op amps or am I doing something incorrectly?
