Silicon Pressure Sensors

The MPX2700A series device is a silicon piezoresistive pressure sensor providing a

highly accurate and linear voltage output — directly proportional to the applied pressure.

The sensor is a single monolithic silicon diaphragm with the strain gauge and a thin–film

resistor network integrated on–chip. The sensor is laser trimmed for precise span and

offset calibration and temperature compensation.

VOLTAGE OUTPUT versus APPLIED DIFFERENTIAL PRESSURE

The differential voltage output of the X–ducer 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).

Figure 1 shows a block diagram of the internal circuitry on the stand–alone

pressure sensor chip.
