FXPS7115D4
Digital absolute pressure sensor, 40 kPa to 115 kPa
12 Media compatibility—pressure sensors only
For more information regarding media compatibility information, contact your local sales
representative.
13 Pressure sensor accuracy (drift over temperature and life)
The absolute pressure accuracy is specified in Figure 23 and Figure 24.
Figure 23 shows the absolute pressure drift over the entire specified temperature range.
The absolute pressure drift over temperature is guaranteed by production testing.
Figure 24 shows a multiplying factor that accounts for the life time drift of the pressure
sensor. The results in Figure 24 have been obtained by qualification testing to conform to
the AEC-Q100[2] (Rev-H) standards.
As an example, at room temperature, the worst case drift that the pressure sensor might
have after accounting for lifetime performance is (1 kPa × multiplying factor) = 2 kPa.
