CT455 XtremeSense™ TMR Contactless Current Sensors

Allegro MicroSystems  CT455 XtremeSense™ TMR Contactless Current Sensors are high-bandwidth and low-noise sensors that enable high-accuracy current measurements for consumer, enterprise and industrial applications. After calibration, these current sensors achieve a total error output of less than ±1% over supply voltage and temperature. The CT455 contactless current sensors are also offered in a user-programmable variant, which allows end-of-line calibration of offset and gain.  These current sensors are compact, feature a simple design, and are equipped with a filter function to reduce the noise on the output pin.
