This application note describes coreless Hall Effect current sensor integrated circuits (ICs) and the common mode field rejection. This document covers the limiting factors in differential current ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...

Allegro Microsystems, LLC introduces two new current sensors that are cost effective and provides precise solutions for AC or DC current sensing in a variety of applications including industrial, ...

Using a resistor and voltage amplifier across it for current sensing presents a conundrum. On one hand, it appears to be near-trivial application of Ohm’s Law via I = V/R. It certainly looks easy: A ...

Improperly terminated VFD cables can generate up to 60 amps of common mode current spikes through facility ground grids, damaging unconnected control and communication equipment. Most electricians ...

Allegro MicroSystems, LLC announces two new current sensor ICs that are economical and precise solutions for AC or DC current sensing in industrial, automotive, commercial, and communications systems.
