Week #11: (11/14-18) Differential & Instrumentation Amplifiers

Post by rjagodowski »

This week we'll investigate Differential Amplifiers and Instrumentation Amplifiers, including the lab exercise found here.

The Op-Amp Difference Amplifier.

The Instrumentation Amplifier The labsheet containing the I.A. can be found here.

Here is the Gain Calculation Practice sheet distributed in class on Wednesday, 11/16.

These are two Excel files to help with calculations and a demonstration of Differential Amplifier operation.

This file will perform the calculations for Differential Mode, Common Mode and CMRR for the Differential Amplifier Circuit built in lab.
