Overview
MOTOROLA Freescale Semiconductor, Inc.
SEMICONDUCTOR TECHNICAL DATA Order this document by MPX2202/D 200 kPa On-Chip Temperature Compensated & Calibrated Pressure Sensors 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.
Features UNIBODY PACKAGE • Temperature Compensated Over 0°C to +85°C • Easy–to–Use Chip Carrier Package Options • Available in Absolute, Differential and Gauge Configurations Application Examples • Pump/Motor Controllers • Robotics MPX2202A/D CASE 344 • Level Indicators • Medical Diagnostics • Pressure Switching • Barometers • Altimeters Figure 1 illustrates a block diagram of the internal circuitry on the stand–alone pressure sensor chip.

Temperature Compensated Pressure Sensor Schematic 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 vacuum.
The output voltage will decrease as vacuum, relative to ambient, is drawn on the pressure...
