Freescale Semiconductor
The sensor system errors is made up of the sensor errors,
amplifier errors and A/D errors. In other words,
Table 2 shows the MPX2010 with the errors converted to
%VFSS. The expected maximum root mean squared error of
the sensor is
= ± 7.19% FS.
With auto-zeroing, the offset calibration, temperature effect
on offset and offset stability is reduced or eliminated,
= +/- 4.42% FS.
The sensor error is calculated using the full-scale pressure
range of the device, 0 to 85°C temperature and 10 V
excitation.
In comparison with the MPXV4006G solution, the expected
accuracy of the system (MPXV4006G + 8 bit A/D) with
auto-zero is 3.1% FS.
