XtremeSense® TMR Sensor

1 MHz Bandwidth Contactless Current Sensor with <1% Total Error

Data Sheets

The CT450 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, anIt supports fixed and programmable field ranges where the CT450 sense and translate the magnetic field into a linear analog output voltage. It achieves a total error output better than ±1.0% over voltage and temperature.

It has less than 300 ns output response time while the current consumption is about 6.0 mA. The CT450 is equipped with a filter function to reduce the noise on the output pin.

The CT450 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.
