The differential amplifier has a unique feature that many circuits don’t have - two inputs. This circuit amplifies the difference between its input terminals. Other circuits with one input actually have another input – the ... It depends on the op amp device itself and matching of the resistor values (more below).

A circuit model of an operational amplifier is shown in Figure 22. The output voltage of the op amp is linearly proportional to the voltage difference between the input terminals by a factor of the gain . However, the output voltage is limited to the range , where is the supply voltage specified by the designer of...

An op-amp with no feedback is already a differential amplifier, amplifying the voltage difference between the two inputs. However, its gain cannot be controlled, and it is generally too high to be of any practical use.

The Differential Amplifier circuit is a very useful op-amp circuit and by adding more resistors in parallel with the input resistors R1 and R3, the resultant circuit can be made to either "Add" or "Subtract" the voltages applied to their respective inputs.
