The CT41x family is a high bandwidth, fast response and ultra-low noise integrated contact current sensors that use Allegro MicroSystems’ patented XtremeSense™ TMR technology to enable high accuracy current measurements for many consumer, enterprise, and industrial applications. It supports eight (8) current ranges where the integrated current carrying conductor (CCC) will handle up to 65 A of current and generates a current measurement as a linear analog output voltage. It achieves a total output error of ±1.0% full-scale (FS) over voltage and the full temperature range.

The CT41x family is offered in an industry standard 8-lead SOIC package that is “green” and RoHS compliant.
