The AG040T Demonstration Board has an ADT923 TMR magnetic switch powered by a three-volt lithium coin cell (included). An LED to show the sensor output. The sensor’s low quiescent power allows the battery to last at least several years with occasional LED use.
A miniature bar magnet is included so you can see for yourself how these remarkable sensors work.
The sensors are 1.1 mm x 1.1 mm x 0.35 mm, and these miniature evaluation boards are just 0.25 x 1.57 inches (6 x 40 mm).
NVE's ADT925-14E Nanopower Switch integrates TMR sensor elements with digital signal processing. Continuous operation allows high frequency switching. The part is packaged in an ultraminiature ULLGA.
