Diodes – AH8500/1: Micropower Linear Hall Effect Sensor Family with Enable/Control Pin


The AH850/1/2/3 is a family of low power/micropower linear hall effect sensors with output voltage ratiometric to supply and magnetic field sense range of ±400G. The high performance AH8501 and AH8503 have trimmed sensitivity accuracy of 3% with a null voltage offset <1% of supply voltage. Designed for a wide range of applications, they are optimized for the supply range of 1.6V to 3.6V consuming only 8.9μA in sleep mode (AH8500/AH8501) and 13μA in micropower mode (AH8502/AH8503). The sensors have a ESD rating of 6kV for robustness.
