The CT455 is a high bandwidth and low noise integrated contactless current sensor that uses Crocus Technology’s patented XtremeSense TMR technology to enable high accuracy current measurements for many consumer, enterprise, and industrial applications. It supports two (2) standard field ranges where the CT455 senses and translates the magnetic field into a linear analog output voltage. It achieves a total error output of less than ±1.0% over supply voltage and temperature after calibration.
CT455 is also available in a user-programmable variant, which enables end-of-line calibration of gain and offset. While the sensor is pre-programmed to compensate for gain and offset temperature drift, the ability to adjust offset and gain relaxes mechanical tolerances during sensor mounting.
It has less than 300 ns output response time while the current consumption is about 6.0 mA.
The CT455 is housed in an 8-lead SOIC package and a very low profile, industry standard 8-lead TSSOP package that are both “green” and RoHS compliant.
