Introduction to Operational Amplifiers

 Abstract

This self-paced class begins with operational amplifier (op amp) concepts and terminology such as op-amp definition, op-amp terminals, op-amp input modes, op-amp basic ideal characteristics, specifications, feedback configurations, etc. This will help you understand real world op-amps and choose the right op-amps for special applications.
