INL Calibration Procedure
The INL correction value varies with the temperature. The typical value is 0.15 LSB at T
0.2 LSB from low to high temperatures.

INL Calibration Table
The calibration of the INL abides by the following rule:
If there is an INL peak (+0.5 LSB) around a specific code, then this peak can be decreased by 0.15 LSB
by writing a “1” on the bit given by the table below for the first level of correction (fifth column). If this is
not sufficient to decrease the INL peak, then you can write a “1” on the bit given by the table in the first
level INL column (fourth column). The effect will be then to decrease the INL by 0.6 LSB (the effect of
columns four and five are added).
The procedure is similar when the INL should be increased (columns one and two).
Example:
The intrinsic INL obtained with the ADC has a peak (+0.5 LSB) around code 128. By writing a “1” on bit 9
of register at address 0x34, you will be able to decrease the INL peak. If this is not sufficient, you can
write another “1” on bit 9 at address 0x31.
