The MikroElektronika Hall Current 10 Click is a compact add on board that provides economical and precise AC or DC current sensing solutions. This board features the ACHS-7194, a fully integrated Hall effect based isolated linear current sensor designed for the current range of 40A from Broadcom Limited. Inside ACHS 7194 is a precise, low offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field that the differential hall sensors convert into a proportional voltage, where after that the user is given the option to process the output voltage as an analogue or digital value. This Click board is suitable for AC or DC current sensing in industrial, commercial, and communications systems.
