Allegro Microsystems (ACS712ELCTR-30A-T) Linear Current Sensor

Linear Current Sensor, Hall Effect, 30A Sensing Current, SOIC-8

Product Overview
The ACS712ELCTR-30A-T is a fully integrated, hall effect based linear current sensor IC in 8 pin SOIC package. It provides economical and precise solutions. The device package allows for easy implementation by the customer. The device consists of a precise, low-offset, linear hall sensor 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 is sensed by the integrated Hall IC and converted 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 Becomes Hall IC which is programmed for accuracy after packaging.
