Op-Amps - Using Operational Amplifiers

Op-amps are like analog building blocks; you can create almost anything with them. Today, we’ll learn how to use these versatile components, alone and with an Arduino.

In fact, the “operational” in the name is a reference to the op-amp's ability to perform mathematical operations on voltages, which is how analog computers represent numbers. Op-amps have been available in integrated circuit (IC) format for nearly 60 years and have become a vital component in analog electronic design. There are two reasons for their popularity: 1 - They are versatile - Op-amps can be configured into dozens of basic circuits. 2 - They are inexpensive - Op-amps are pretty cheap! One of the devices we will look at today costs about 10 cents per op-amp. You can also use operational amplifiers to “glue” analog and digital electronics; in fact, one of the demos today uses an op-amp with an Arduino. Aside from that, we’ll also learn how op-amps work, how to configure them into several basic “analog building block” circuits, how to build a light-sensitive switch using them, and how to turn a single power supply into a dual one using an op-amp.

One more reason to consider using them in your designs! Hope you enjoy the video. Bill
