Current-sense amp integrates precision shunt resistor, in single package

Leave a Comment / Tech News Updates / By TechExpert

Texas Instruments says it is making, “high-accuracy measurement more attainable with the first current-sense amplifier to integrate a high-precision, low-drift 2 mΩ shunt resistor,” – the device can cut calibration effort, system cost, and footprint for test and measurement, communications load monitoring, and power supplies. For highly accurate measurements over a wide temperature range, TI’s …

Decade resistor box with jumpers

Leave a Comment / Tech News Updates / By TechExpert

I have spent a lot of time over the years prototyping electronic circuits and the amount of resistors that have ended up in the trash because they are so cheap you don’t bother to keep them tidy or organized once you take them out of their organized storage – you know the story. One potential …

Make a Variable Resistor boxes with 1 Million Settings

Leave a Comment / Tech News Updates / By TechExpert

College physics lab we got to use these variable resistance ‘boxes’. They had two inputs and six dials, and could generate one million different resistances across the two inputs. I knew I had to have one, and why not make it myself? This tutorial demonstrates how to build one for yourself for pretty cheap. Materials: …
