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 ...

The LM358 family of dual op amps is among those hoary industry work-horse devices that are inexpensive and still have their uses. These parts’ outputs can approach (and for the inputs even include) ...

Measuring this one vital parameter (Input Offset Voltage) provides a simple means of determining if the DUT (Device Under Test) is either good or bad. The circuit is very simple, requiring only four ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...
