Used as a buffer amplifier, to eliminate loading effects or to interface impedances (connecting a device with a high source impedance to a device with a low input impedance). Due to the strong feedback, this circuit
tends to get unstable when driving a high capacity load. This can be avoided by connecting the load through a
resistor.
