The MPX2102/MPXV2102G 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 chip is laser trimmed for
precise span and offset calibration and temperature compensation.

VOLTAGE OUTPUT versus
APPLIED DIFFERENTIAL PRESSURE
The differential voltage output of the sensor is
directly proportional to the differential pressure applied.
The absolute sensor has a built–in reference vacu-
um. The output voltage will decrease as vacuum,
relative to ambient, is drawn on the pressure (P1) side.
The output voltage of the differential or gauge sensor
increases with increasing pressure applied to the
pressure (P1) side relative to the vacuum (P2) side.
Similarly, output voltage increases as increasing vacu-
um is applied to the vacuum (P2) side relative to the
pressure (P1) side.
Preferred
devices are Motorola recommended choices for future use
and best overall value.
