Product Overview

The ACS712 provides economical and precise solutions for AC or DC current sensing in industrial, automotive, commercial, and communications systems. 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 BiCMOS Hall IC, which is programmed for accuracy after packaging.
  • Low-noise analogue signal path
  • Device bandwidth is set via the new FILTER pin
  • Small footprint, low-profile
  • 1.2 mΩ internal conductor resistance
  • Output voltage proportional to AC or DC currents
  • 66 to 185 mV/A output sensitivity
  • Factory-trimmed for accuracy
  • Extremely stable output offset voltage
  • Nearly zero magnetic hysteresis
  • Ratio metric output from supply voltage

Applications

Automotive, Sensing & Instrumentation, Industrial, Power Management, Communications & Networking
