- The Operational Amplifier (op amp) was invented in the 40’s. Bell Labs filed a patent in 1941 and many consider the first practical op amp to be the vacuum tube K2-W invented in 1952 by George Philbrick. - Texas Instruments invented the integrated circuit in 1958 which paved the way for Bob Widlar at Fairchild inventing the uA702 solid state

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

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+

Week #1: Audio amplifier Week #2: Microphone circuit The audio amplifier project is more difficult and time-consuming than the microphone pre-amp, so part of week #2 may be used to finish the audio amp. All breadboarding and testing can and should be done in lab. Soldering and hardwiring can and should be done outside lab.

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 ...
