DESCRIPTION
The Grove – ±5A DC/AC Current Sensor (ACS70331) is a high precision DC/AC current sensor based on ACS70331. It 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. This senses the magnetic field generated by the current flowing through the low resistance 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.
FEATURES
- 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)
