Figure 2 illustrates the absolute sensing chip in the basic
Super Small Outline chip carrier (Case 1317). Figure 3
illustrates a typical application circuit (output source current
operation).
Figure 4 shows the sensor output signal relative to
pressure input. Typical minimum and maximum output curves
are shown for operation over 0 to 85°C temperature range.
The output will saturate outside of the rated pressure range.
A fluorosilicone gel isolates the die surface and wire bonds
from the environment, while allowing the pressure signal to
be transmitted to the silicon diaphragm. The MPXH6250A
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.
