In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

This file type includes high-resolution graphics and schematics when applicable. Most data-acquisition systems with wide dynamic range need a method of adjusting the input-signal level to the ...

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 ...

Accurate signal conditioning and high-resolution measurements are no longer limited to industrial or instrumentation applications. Designers of portable consumer- electronic equipment also need to ...

ST has created a dual precision op-amp for automotive sensor signal conditioning, with 20µV input offset voltage and 100nV/°C drift, and operation over 4 to 36V and -40 to 125°C. Input common mode ...

As analog-to-digital and digital-to-analog converter resolutions increase and power supply voltages decrease, the size of a least significant bit becomes smaller. This makes signal-conditioning tasks ...
