4.3. Temperature Compensation
The relationship between the temperature coefficient
of the magnet and the corresponding TC and TCSQ
codes for linear compensation is given in the following
table. In addition to the linear change of the magnetic
field with temperature, the curvature can be adjusted
as well. For this purpose, other TC and TCSQ combi-
nations are required which are not shown in the table.
Please contact Micronas for more detailed information
on this higher order temperature compensation.
The HAL8x5 and HAL810 contain the same tempera-
ture compensation circuits. If an optimal setting for the
HAL8x5 is already available, the same settings may
be used for the HAL810.
