These methods don’t correct the drift, though. Precision op amps are available to solve these problems. Zero-drift amplifiers feature an input offset voltage of less than a microvolt.

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two f… ...

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 … ...

In the last column (Simulating op amp noise) I showed how to do simple and fast simulations on op amp circuits to get a handle on what kind of noise performance to expect. As can be expected with any ...

Therefore, it is often a practical necessity to power op-amp circuits from a single polarity supply. But single-supply operation has its drawbacks: It requires additional passive components in each ...

As a result, precision IC op amps have been created to address these needs. Three examples here illustrate some common problems and solutions. Zero-Drift Amplifiers ...
