Overview

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.

  • User-programmable field range: □ 6 to 24 mT
  • Preset magnetic field ranges: □ 0 to 6 mT □ ±6 mT
  • Linear analog output voltage
  • Common mode field rejection: -50 dB
  • 1 MHz bandwidth
  • Response time: <300 ns
  • Reference voltage output for unipolar/bipolar field measurements
  • Supply voltage: 4.75 to 5.50 V
  • Low noise performance
  • Filter pin to reduce noise on output
