The Grove - ±5A DC/AC Current Sensor (ACS70331) is a high precision DC/AC current sensor based on ACS70331. The ACS70331EESATR-005B3 is Allegro’s high sensitivity,current sensor IC for <5 A current sensing applications. It incorporates giant magneto-resistive (GMR) technology that is 25 times more sensitive than traditional Hall-effect sensors to sense the magnetic field generated by the current flowing through the low resistance, integrated primary conductor. 


The Grove - ±5A DC/AC Current Sensor (ACS70331) can measure both the DC current and the AC current up to 5A with a base sensitivity of 200mV/A.

The human body is forbidden to touch the module during the test, otherwise there is danger of electric shock.


  • 1 MHz bandwidth with response time <550 ns
  • Low noise: 8 mA(rms) at 1 MHz
  • 1.1 mΩ primary conductor resistance results in low power loss
  • High DC PSRR enables use with low accuracy power supplies or batteries (3 to 4.5 V operation)
