FXPS7115D4

Digital absolute pressure sensor, 40 kPa to 115 kPa

17 Mounting recommendations

The package should be mounted with the pressure port pointing away from sources of

debris which might otherwise plug the sensor.

A plugged port exhibits no change in pressure and can be cross checked in the user

software.

Refer to NXP application note AN1902[1] for proper printed circuit board attributes and

recommendations.
