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 <lt/>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.

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