Notes:
1. Unless otherwise specified the typical values are defined at TA = +25ºC and VDD = 12V
2. Guaranteed by correlation with production test at B=28mT and verified by characterization
3. The programming step is <0.5% of the programmed BOP value for |BOP| ⥠6mT and <0.02mT for |BOP| ⤠6mT at TA = +25ºC
4. Programming of very low hysteresis magnitude (BOP â BRP < 1mT) could lead to output toggling due to noise and mechanical looseness
in the magnetic system.
5. TC target values
6. The Temperature Coefficient is calculated using the following formula:
TC

(BOPTA2 ï BRPTA2 ) ï (BOPTA1
(BOPTA1 ï BRPTA1) * (TA2
