Figure 11b. Conditioned Sensor
Output
Figures
11a
and
11b
above
illustrate
the
performance of an unconditioned sensor output and
a
conditioned
sensor
output
versus
stimulus
(pressure) and temperature. It can be seen that
Figure 11a has a range of only 170 mV (maximum
range with a 5V supply) and has a non-linear
response over a 0-100 psi range. The sensitivity of
the
unconditioned
output
will
also
drift
over
temperature, as illustrated by the three slopes. The
MLX90308 corrects these errors and amplifies the
output to a more usable voltage range as shown in
Figure 11b.
