Crocus Technology CT41x XtremeSense® TMR Current Sensors

Crocus Technology CT41x XtremeSense® TMR Current Sensors are high bandwidth and ultra-low-noise integrated contact current sensors utilizing the patented XtremeSense® TMR technology. The technology enables high accuracy current measurements for many consumer, enterprise, and industrial applications. These components support eight current ranges where the integrated current-carrying conductor (CCC) will handle up to 65A of current and generates a current measurement as a linear analog output voltage. The 8-lead SOIC packaged CT41x sensors achieve a total output error of about ±1.0% full-scale (FS), a 300ns output response time, and a 6.0mA current consumption. A filter function reduces the noise on the output pin.
