Figure 2 illustrates a typical application circuit (output
source current operation).
Figure 3 shows the sensor output signal relative to
pressure input. Typical minimum and maximum output curves
transmitted to the silicon diaphragm. The MPXHZ6250A
series pressure sensor operating characteristics, internal
reliability and qualification tests are based on use of dry air as
the pressure media. Media 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.

The output will saturate outside of the rated pressure range.
A gel die coat isolates the die surface and wire bonds from
the environment, while allowing the pressure signal to be
