SEMICONDUCTOR TECHNICAL DATA by MPX2202/D

Motorola Preferred Device

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

0 to 200 k Pa (0 to 29 psi)

precise span and offset calibration and temperature compensation. They are designed

40 m V FULL SCALE SPAN

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

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 MPX2202ASX/GSX pressure (P1) side relative to the vacuum (P2) side. CASE 344F

Similarly, output voltage increases as increasing vacu-
