ACS70310LKTATN-005B5-C | Allegro

Programmable Linear Hall-Effect Sensor IC, ACS70310LKTATN-005B5-C, Allegro

The ACS70310LKTATN-005B5-C IC incorporates a Hall element with BiCMOS integrated circuitry to provide a fully monolithic linear current sensor IC. The IC is sensitive to magnetic flux density orthogonal to the IC package surface and the output is an analog voltage proportional to the applied flux density. The ACS70310LKTATN-005B5-C is designed to be used in conjunction with a ferromagnetic core to provide highly accurate current sensing. The gain and offset drift over temperature are factory-programmed at Allegro and delivers a solution with ±1% sensitivity error and ±5 mV offset error from 25°C to 150°C.
