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

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.
(often more desirable in error budget calculations) and the
calculations are more straightforward for the user.
Freescale’s specified pressure sensor linearities are based
on the end point straight line method measured at the
midrange pressure.
