Unless otherwise specified the typical values are defined at TA = +25ºC and VDD = 12V
Guaranteed by correlation with production test at B=12mT and verified by characterization
The programming step is <0.5% of the programmed BOP value for |BOP| ≥ 6mT and <0.02mT for |BOP| ≤ 6mT at TA = +25ºC
Programming of very low hysteresis magnitude (BOP - BOP < 1mT) could lead to output toggling due to noise and mechanical
looseness in the magnetic system.
TC target values
The Temperature Coefficient is calculated using the following formula:
TC

(B_OPTA2  B_RPTA2 )  (B_OPTA1
(B_OPTA1  B_RPTA1) * (T_A2
 B_RPTA1
 T_A1)
)
