Differential Opamp.

Posted by Mr Mallon on May 23, 2013

Here is the set up for an opamp set to differential mode.

This set up amplifies the difference between the two voltages.

daum_equation_1369347773825

Looking at the input and feedback resistors we have:
daum_equation_1369348006205

Click the green arrows of V2 and V1 and check out that the difference between V2 and V1 is multiplied by 2.

This is an example of a differential amplifier.
