Top Features

AEC-Q100 qualified
Differential Hall sensing rejects common-mode fields
1.2 mΩ primary conductor resistance for low power loss and high inrush current withstand capability
Integrated shield virtually eliminates capacitive coupling from current conductor to die, greatly suppressing output noise due to high dv/dt transients
Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
High-bandwidth 120 kHz analog output for faster response times in control applications
Filter pin allows user to filter the output for improved resolution at lower bandwidth
Patented integrated digital temperature compensation circuitry allows for near closed-loop accuracy over temperature in an open-loop sensor
Filter pin simplifies bandwidth limiting for better resolution at lower frequencies
5 V, single supply operation
