Introduction

The CT416 is a high bandwidth and ultra-low noise integrated contact current sensor that uses Allegro patented XtremeSense™ TMR technology to enable high accuracy current measurements for many industrial, consumer, and automotive applications. The device supports eight current ranges where the integrated current carrying conductor (CCC) will handle up to 65 A of current and generates a current measurement as a linear analog output voltage. The device achieves a total output error of about ±1.0% full-scale (FS). The device has a ~300 ns output response time while the current consumption is about 6.0 mA and is immune to common-mode fields. The CT416 has a filter function to reduce the noise on the output pin. The CT416 is offered in an industry-standard 8-lead SOIC package that is green and RoHS compliant.
