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 ...

Operational amplifiers (op amps) are a staple in modern electronics. Found in everything from industrial flow metering to ultrasound imaging, versatility is their appeal. This building block is unique ...

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 ...

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 ...

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., ...

With over 35 years of refinement, op amps are a staple of analog designers. Have we reached the limit of what can be done with monolithic op amps? For many applications, IC op amps are clearly the ...

STMicroelectronics has released the TSB192, a dual zero-drift op amp for precision signal conditioning, with a 4 V to 36 V ...

TI has revealed early fruits from the latest in its long-running series of BiCom advanced bipolar processes: the 27V 200MHz low-noise OPA2810 and the 36V zero-drift 14MHz OPA189, which are aimed at ...

As one of the basic building blocks used in an array of consumer, industrial, scientific and other applications, the operation amplifier (op amp) is amongst the most widely used electronic devices.

One of my first jobs as a freshly minted graduate engineer involved the maintenance of a set of analogue chart recorders. They were museum pieces by the early 1990s: a motorized roll of graph paper ...
