Description
Initial value (Sensinit)
Maximum value of sensitivity (Sens) in range
Initial value (VOUT(Q)init)
Maximum value of quiescent voltage output
(VOUT(Q)) in range; B = 0 G
Initial value of sensitivity temperature coefficient
range (TCSensinit)
Maximum value of sensitivity temperature coef-
ficient (TCSens) in range
POL bit, switches polarity (causes VOUT to
increase with a negative [north polarity] field
applied to the branded face of the device)
LOCK bit, enables permanent locking of all pro-
gramming bit fields in the device
