50 kPa Uncompensated

Silicon Pressure Sensors

The MPX53/MPXV53GC series silicon piezoresistive pressure sensors provide 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 compensating 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 differential voltage output of the sensor is directly proportional to the differential

pressure applied.

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).
