NOTES
1) A stable pressure reading of the given resolution requires taking the average of 2 to 4 subsequent pressure
values due to noise of the ADC.
2) Maximum error of pressure reading over the pressure range.
3) With the second-order temperature compensation as described in Section “FUNCTION". See next section
for typical operating curves.
4) The long-term stability is measured with non-soldered devices
TEMPERATURE OUTPUT CHARACTERISTICS
This temperature information is not required for most applications, but it is necessary to allow for temperature
compensation of the pressure output. The reference temperature is 20°C.
