This Design Idea offers a new instrumentation-amplifier topologythat improves ac CMR (common-moderejection). Because it uses discrete amplifiers,you can customize it for the lowestpower, price, noise, ...
You can implement many fundamental building-block circuits such as a difference amplifier (DA) or instrumentation amplifier (IA) using discrete or integrated components. Design engineers often debate ...
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 ...
The XTR105, XTR112, and XTR114 from Burr-Brown are a family of two-wire, 4-20 mA current-loop transmitters with instrumentation-amplifier input stages. The front end is designed to be used with a ...
Measuring the body’s electrical signals is a neat trick… if you can get your equipment dialed in enough to establish dependable measurements. The technique is called Surface ElectroMyography (SEMG) ...
High-side current-sense amplifiers (CSAs) are principally used for monitoring the current from a positive supply rail. However, applications like ISDN and telecom power supplies require CSAs that ...
