DESCRIPTION
The CT452 is a high-bandwidth and low-noise integrated zero-loss contactless current sensor that uses Allegro patented XtremeSense TMR technology to enable high-accuracy current measurements for many consumer, enterprise, and industrial applications. It supports two field ranges where the CT452 senses and translates the magnetic field into a linear analog output voltage.
