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.
