Calibration
The GLOBOFF register is needed to adjust the sensor cell to the internal A/D converter
range. The TGAIN, TOFFL and TOFFQ registers are used for the temperature
compensation. These registers together with the linearization table have to be
programmed to achieve the full sensor performance.
For a proper calibration of the compensation registers and the linearization table it is
proposed to measure the sensor at a minimum of two different temperatures (e.g. 25 °C,
100 °C) and 3 pressures, depending on the desired pressure range. To set up an
appropriate calibration sequence support of the IFX sensor application group is
available.
