Grove - 2.5A DC Current Sensor (ACS70331)
The Grove - 2.5A DC Current Sensor (ACS70331) is a high precision DC current sensor based on the ACS70331. It is an Allegro’s high sensitivity current sensor IC for <2.5 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 - 2.5A DC Current Sensor (ACS70331) can measure the DC current up to 2.5A and has a base sensitivity of 800mV/A. This sensor does not support AC current.
- 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)
