Indirect Current Feedback Instrumentation Amplifier Applications Guide

Analog Devices Inc

The goal of this module is to provide an understanding of the indirect current feedback (ICF) architecture of instrumentation amplifiers and to give some applications insight to leverage its benefits in precision analog designs. The traditional three op-amp instrumentation amplifier architecture will be discussed and then compared to the indirect current feedback architecture. Finally, several application circuits that benefit from indirect current feedback will be presented.
