ON–CHIP TEMPERATURE COMPENSATION, CALIBRATION AND SIGNAL CONDITIONING

The performance over temperature is achieved by inte-

grating the shear–stress strain gauge, temperature com-

pensation, calibration and signal conditioning circuitry onto a

single monolithic chip.

Figure 2 illustrates the gauge configuration in the basic chip

carrier (Case 482). A fluorosilicone gel isolates the die surface

and wire bonds from the environment, while allowing the pres-

sure signal to be transmitted to the silicon diaphragm.

The MPXV5004G series sensor operating characteristics

are based on use of dry air as pressure media. Media, other

than dry air, may have adverse effects on sensor performance

and long–term reliability. Internal reliability and qualification

test for dry air, and other media, are available from the factory.

Contact the factory for information regarding media tolerance

in your application.

Figure 3 shows the recommended decoupling circuit for in-

terfacing the output of the MPXV5004G to the A/D input of

the microprocessor or microcontroller. Proper decoupling of

the power supply is recommended.

Figure 4 shows the sensor output signal relative to pres-

sure input. Typical, minimum and maximum output curves

are shown for operation over a temperature range of 10

°C to

°C using the decoupling circuit shown in Figure 3. The

output will saturate outside of the specified pressure range.
