KP253

Digital Absolute Pressure Sensor

Functional Description

2.5

Transfer Function Temperature

Triggering the temperature command (see Section 2.7.1.4) the KP253 provides the ambient temperature.

Temperature Transfer Function Characteristics

The following calibration is adjusted with the parameters ST and offsT:

Note: The points TIN,1/LSBOUT,1 and TIN,2/LSBOUT,2 define the calibrated transfer function and not the operating

range. The operating temperature range is defined by the parameter 2.7 “Operating temperature” on
