pressure range. There are two basic methods for calculating
nonlinearity: (1) end point straight line fit (see
(2) a least squares best line fit. While a least squares fit gives
the “best case” linearity error (lower numerical value), the
calculations required are burdensome.

die surface and wire bonds from the environment, while
allowing the pressure signal to be transmitted to the silicon
diaphragm.

other than dry air may have adverse effects on sensor
performance and long term reliability. Contact the factory for
information regarding media compatibility in your application.
Refer to application note AN3728, for more information
regarding media compatibility.
