CT456 Overview
Key Specifications
Description
The CT456 is a high-bandwidth and low-noise integrated zero-loss contactless current sensor that uses Allegro patented XtremeSense tunnel magnetoresistance (TMR) technology to enable high-accuracy current measurements for many consumer, enterprise, and industrial applications. The device supports a preprogramed 6 mT field range where the CT456 senses and translates the magnetic field into a linear analog output voltage.
Key Features
- User-programmable field range: □ 6 to 8 mT □ 12 to 48 mT
- Preset magnetic field ranges: □ ±6 mT
- AEC-Q100 Grade 1 [1] automotive qualified (A variants only)
- Optimized for high dV/dt applications
- Differential sensing for stray-magnetic-field suppression
