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 voltage ...

There are many parameters to consider when designing a circuit using an operational amplifier (op amp) including the op-amp’s gain bandwidth (GBW) product, offset voltage and quiescent current. In ...
