Allegro MicroSystems CT452 1MHz Bandwidth Contactless Current Sensor
Allegro MicroSystems CT452 1MHz Bandwidth Contactless Current Sensor is a high bandwidth low noise integrated zero-loss contactless current sensor. The CT452 uses patented XtremeSense® TMR technology. This enables high-accuracy current measurements for consumer, enterprise, and industrial applications. The device supports six field ranges where the CT452 senses and translates the magnetic field into a linear analog output voltage. It achieves a total error output of less than ±1.0% over voltage and temperature.
