CT220 Description
The CT220 is a high-linearity and high-resolution contactless current sensor from Allegro developed on its patented XtremeSense™ TMR technology. The CT220 measures the magnetic field of the current flowing through a busbar or printed circuit board (PCB) trace and converts it to an analog output voltage that represents the field and therefore current. As a contactless current sensor, it has an inherently high...
