ACS712 - 5A Range Current Sensor Module

ACS712 5A Current Sensor Module 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 which the Hall IC converts into a proportional voltage. It provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems. It is provided in a small surface-mount SOIC8 package. The lead frame is plated with 100 percent matte tin, which is compatible with standard lead (Pb) free printed circuit board assembly processes.
