20 to 250 kPa, Manifold absolute pressure sensor, on-chip signal conditioned, temperature

compensated and calibrated

term reliability. Contact the factory for information regarding media compatibility in your

application.

Figure 5 shows the recommended decoupling circuit for interfacing the output of the

integrated sensor to the A/D input of a microprocessor or microcontroller.

Figure 6 shows the sensor output signal relative to pressure input. Typical, minimum, and

maximum output curves are shown for operation over a temperature range of 0 °C to 85

°C using the decoupling circuit shown in Figure 5. The output will saturate outside of the

specified pressure range.
