Figure 4. Output versus Absolute Pressure

TRANSFER FUNCTION:

Vout = Vs* (.009*P–.095) ± Error

VS = 5.0 Vdc

TEMP = 0 to 85

°C

Figure 4 shows the sensor output signal relative to pres-

sure 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 gel die coat isolates the die surface and wire bonds

from the environment, while allowing the pressure signal

to be transmitted to the sensor diaphragm. The gel die

coat and durable polymer package provide a media resis-

tant barrier that allows the sensor to operate reliably in

high humidity conditions as well as environments contain-

ing common automotive media. Contact the factory for

more information regarding media compatibility in your

specific application.
