This is the simplest closed-loop operational amplifier configuration.
The gain of the circuit is very nearly 1.00. It is useful because its
input resistance is very high. It is often used as a buffer between devices
to avoid loading errors.
You can vary the slider on the left to change the input voltage.
If you attempt to make the output voltage exceed +14 or -14
volts, the output will "saturate".
