Are op amps all the same? Why are some better than others at certain tasks? How are some op amps better than others? Below, we review some of the most popular types of op amps, then take a close-in ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

This chapter of the book deals with data conversion and associated signal conditioning circuitry involving the use of op amps. Data conversion is a very broad topic, and this chapter will provide only ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

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 ...

Modeling on Mondays: A Comprehensive and Speedy Op-Amp SPICE Model Despite the monolithic op amp being older than SPICE simulators, comprehensive op-amp SPICE modeling left a lot to be desired—until ...

Guest columnist Harry Holt, applications engineer at Analog Devices, believes that two into one is a relevant question when designs need more than one operational amplifier. In designs requiring ...

Learn how to model with AI an operational amplifier precision half-wave rectifier, which can help overcome challenges ...

Delivering many improved major specs over traditional LM324 op-amps, but with rail-to-rail inputs and outputs, STMicroelectronics has introduced a 6MHz all-rounder op-amp family that will operate from ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...
