ALLEGRO CT426-HSN830MR

The CT426 is a high-bandwidth, ultra-low-noise integrated contact current sensor utilizing XtremeSense TMR technology, delivering high-accuracy current measurement for a wide range of industrial, consumer, and automotive applications. The device supports eight current ranges; its integrated current-carrying conductor handles currents up to 65 A and produces a linear analog output voltage as the current measurement. The device achieves a total output error of less than ±1.0% full scale. It features an output response time of approximately 300 ns, a current consumption of approximately 6.0 mA, and immunity to common-mode magnetic fields. The CT426 incorporates a filtering function to reduce noise on the output pin. The CT426 is offered in an industry-standard 8-pin SOIC package that is green-compliant and RoHS-compliant.
