  • Small footprint, low-profile SOIC8 package.
  • 2 mΩ internal conductor resistance.
  • 1 kV RMS minimum isolation voltage from pins 1-4 to pins 5-8.
  • 0 V, single supply operation.
  • 66 to 185 mV/A output sensitivity.
  • Output voltage proportional to AC or DC currents.
  • Factory-trimmed for accuracy.
  • Extremely stable output offset voltage.
  • Nearly zero magnetic hysteresis



  • The Allegro ACS712 provides economical and precise solutions for AC or DC current sensing in industrial, Commercial,and communications systems
  • The device package allows for easy implementation by the customer
  • Typical applications include motor control, load detection and management, switch-mode power supplies, and overcurrent fault protection
  • The device is not intended for automotive applications
  • The device 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
  • 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



  • Typical applications include motor control, load detection and management, switched-mode power supplies, and over current fault protection.
