The CT427 is a high-accuracy, integrated contact current sensor utilizing Allegro's XtremeSense TMR technology. It offers ultra-low noise and a total output error of less than 1.0% full-scale across eight selectable current ranges up to 65 A. The device provides a linear analog output voltage and features integrated overcurrent detection (OCD) with a fault output pin (FLT). Ideal for industrial, consumer, and automotive applications, it ensures high precision current measurements with a fast 300 ns response time and immunity to common mode fields.
