ACS71240 - Allegro

ACS71240 Galvanically Isolated Current Sensor

The Allegro™ ACS71240 current sensor IC is an economical and precise solution for AC or DC current sensing in industrial, automotive, commercial, and communications applications. The device consists of a precise, low-offset linear Hall sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this coppe.

Features

• AEC-Q100 automotive qualified
• Differential Hall sensing rejects common-mode fields
• 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
• Patented integrated digital temperature compensation circuitry allows for near closed-loop accuracy over temperature in an open-loop sensor .
