The ACHS-719x product series is a fully integrated Hall Effect-based isolated linear current sensor device family designed for AC or DC current sensing in industrial, commercial, and communications systems. The family consists of products with a sensing current ranging from ±10 A to ±50 A. The devices offer a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current generates a magnetic field that the Hall IC converts into a proportional voltage. Device accuracy is optimized through the use of differential Hall transducers.

Extended Description

Device accuracy is optimized through the close proximity of the magnetic signal to the differential Hall transducers. A precise, proportional voltage is provided by the low-offset, chopper-stabilized CMOS Hall IC, which is programmed for accuracy after packaging. The output of the device has a positive slope (> VOUT(Q)) when an increasing current flows through the primary copper conduction path (from pins 1 - 2 to pins 3 - 4), which is the path used for current sampling.
