Introduction

CT426 is a high-bandwidth, ultra-low-noise integrated contact current sensor that utilizes Allegro's patented XtremeSense™ TMR technology to enable high-accuracy current measurement for a wide range of industrial, consumer, and automotive applications. The device supports eight current ranges, and its integrated current-carrying conductor (CCC) can handle currents up to 65A, generating current measurements as a linear analog output voltage. The device's total output error is less than ±1.0% of full scale (FS). The device features an output response time of approximately 300ns, current consumption of approximately 6.0mA, and immunity to common-mode fields. The CT426 incorporates filtering to reduce noise at the output pin. The CT426 is offered in an industry-standard 8-pin SOIC package and is compliant with green and RoHS standards.
