The Grove 2.5A DC Current Sensor(ACS70331) is a high-precision DC current sensor based on ACS70331. The ACS70331EESATR-2P5U3 is 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.
Note: Do not touch the module while being tested due to the risk of being shocked.
- 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)
