SERIES

The MPX2202/MPXV2202G device series 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. They are designed

for use in applications such as pump/motor controllers, robotics, level indicators, medical

diagnostics, pressure switching, barometers, altimeters, etc.

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.
