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 ...

Driven by architectural, process, circuit design, and packaging improvements, this low-cost building-block device is available in a plethora of performance choices to suit any design. Ever since ...

An op amp, or operational amplifier is, to quote Tamara Schmitz of Intersil, “the main building block of analog systems.” The list of these systems is long, including filters, rectifiers, detectors, ...

The op amp enables designers to solve a multitude of problems, and its uses are limited only by the imagination Operational amplifiers (op amps) are a staple in modern electronics. Found in everything ...

Analog Devices has created a fast power op-amp that can handle ±55V rails and ±1A outputs, with a digital control bus for setting internal parameters. Called ADHV4710, the output can swing ±52V with ...

Normally, if you want to control the gain of an amplifier, you’ll use a variable resistor. You know, like a volume control. But what if you want to control the amplifier’s gain with a voltage?

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 ...
