10 kPa Uncompensated

Silicon Pressure Sensors

The MPX10 and MPXV10GC series devices are silicon piezoresistive pressure sensors

providing a very accurate and linear voltage output — directly proportional to the applied

pressure. These standard, low cost, uncompensated sensors permit manufacturers to

design and add their own external temperature compensation and signal conditioning

networks. Compensation techniques are simplified because of the predictability of

Motorola’s single element strain gauge design. Figure 1 shows a schematic of the internal

circuitry on the stand–alone pressure sensor chip.

VOLTAGE OUTPUT versus APPLIED DIFFERENTIAL PRESSURE

The output voltage of the differential or gauge sensor increases with increasing pressure

applied to the pressure side (P1) relative to the vacuum side (P2). Similarly, output voltage

increases as increasing vacuum is applied to the vacuum side (P2) relative to the pressure

side (P1).
