The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...

In many op-amp applications, wide closed-loop bandwidth isn't as important as low phase shift. Yet in a typical case of an amplifier with a gain of −20, the conventional LM741 has about 0.6° of phase ...

The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...

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 ...

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 ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

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 ...

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 ...

STMicroelectronics’ latest precision op amp offers accuracy, speed, and stability, and can maintain precision parameters ...
