The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic ...

By using op amps powered from a bipolar supply and ground-referencing the sensor signals, the op amp’s output will be at zero volts (ground) with no signal present. It can swing positive or negative ...

This article explains the basic operation of general-purpose, voltage-feedback operational amplifiers. In addition, it points out some special things to look for in high-speed op amps. An op amp ...

There is a 1946 patent for an early use of op amp concepts (Reference 1), although that name was not used at the time. Raggazinni is often credited with coining the term “operational amplifier” in ...
