ACHS-7125 Datasheet | Broadcom

Description The Broad® ACHS-7124/7125 product series is a fully integrated Hall Effect-based isolated linear current sensor device family designed for AC or DC current sensing in industrial, mercial, and munications systems. Each of the ACHS-7124/7125 consists of 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 Hall IC converts into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. 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 4 oz copper conduction path (from pins 1 and 2, to pins 3 and 4), which is the path used for current sampling. The internal...
