HAL® 700, HAL® 740 Dual Hall-Effect Sensors with Independent Outputs
The HAL 700 and the HAL 740 are monolithic CMOS Hall-effect sensors consisting of two independent switches controlling two independent open-drain out-puts. The Hall plates of the two switches are spaced2.35 mm apart.
The devices include temperature compensation and active offset compensation. These features provide excellent stability and matching of the switching points in the presence of mechanical stress over the whole temperature and supply voltage range.
The sensors are designed for industrial and automotive applications and operate with supply voltages from 3.8 V to 24 V in the ambient temperature range from −40°C up to 125°C.
The HAL 700 and the HAL 740 are available in the SMD-package SOT89B-2.
