MSPEXR27IE0S0A
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.
