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.
