Description:

The heart of the ACS712 lies in a precise, low-offset, linear Hall-effect sensor circuit. This sophisticated circuit is designed to accurately measure magnetic fields and convert them into proportional voltage outputs. A critical component of the IC is its integrated copper conduction path. This carefully designed path is situated very close to the surface of the die, optimizing the interaction between the current being measured and the Hall-effect sensor.
