Differential amplifier

The differential amplifier allows the subtraction of two input voltages or cancellation of a signal common the

two inputs. It is useful as a computational amplifier in making a differential to single-end conversion or in

rejecting a common mode signal. Figure 4. shown the differential amplifier using EC5741.

If the resistor ratios are equal (i.e. R1=R3 and R2=R4), then

Instrumentation Amplifier

The input impedance of the previous differential amplifier is set by the resistors R1, R2, R3, and R4. To

maintain the high input impedance, one can use a voltage follower in front of each input as shown in the

following two instrumentation amplifiers.
