In an effort to simplify the operational amplifier, one must not forget that the internal circuitry of an op-amp is more than just a “black box”. All operational amplifiers are integrated circuits (ICs), and Figure 4 illustrates the components that work together to achieve what we know to be an op-amp. -+ Zoutput Zinput Vdep V-Output V+

Operational Amplifier Circuits as Computational Devices So far we have explored the use of op amps to multiply a signal by a constant. For the inverting amplifier the multiplication constant is the gain R2 − R1 and for the non inverting amplifier the multiplication constant is the gain R2 1+ R1. Op amps may also perform other

The LM386 is a type of operational amplifier (Op-Amp). Operational amplifiers have a basic task. They take an input potential (voltage) and produce an output potential that’s tens, hundreds, or thousands of times the magnitude of the input potential. In an amplifier circuit, the LM386 takes an audio input signal and increases its potential anywhere from 20 to 200 times.
