Designing the instrumentation amplifier, with its few external components, appears to be a simple task, but to obtain a reliable design, you must avoid certain traps. You must correctly match the ...

These days there a large number of sensors and analog circuits that are “controller friendly” meaning that their output signal is easily interfaced to the built-in Analog to Digital Convertors (ADCs) ...

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 ...

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, ...

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 ...

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp INA ...

The AD8295 precision instrumentation-amplifier front end from Analog Devices uses 50% less board space than competing amplifier solutions for industrial process controls, precision data acquisition ...

The dual approach of digital and analog lock-in amplifier technologies has continued to advance the precise extraction of weak signals from noise-laden environments. These devices are indispensable in ...
