One of the biggest problems for designers of op-amp circuitry arises when the circuit must be operated from a single supply, rather than ± 15 V. This application note provides working circuit examples ...

The MAX74810, which is fully specified over the extended industrial temperature range of −40 to +125°C, is housed in an ...

Operational amplifiers (commonly called op amps) are a ubiquitous building block for designing electronic circuits. Today, these devices are fabricated as small integrated circuits, but the concept ...

The term rail-to-rail refers to the ability of an op amp to achieve an output or input that can vary over the full range of the dc supply voltages. This feature is realized with CMOS circuits. For ...

Here are four examples of op amp models (schematics and symbols). There's variety of ways to model behaviors, these are simply four possible approaches. Copy and modify them anyway you like. Over the ...

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 ...

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 ...

Operational amplifiers (op amps) are almost the perfect amplifier. As long as you keep a few important details in mind, their imperfections will seem invisible. Figure 1. This simple non-inverting op ...

How do you get the input of an op-amp to work below the negative-most supply rail?, I asked. Now I know – thanks to the patience of ADI field application engineer Andreas Koch. It was not just any ...
