1 / 8 page 1 Motorola Sensor Device Data 100 kPa On-Chip Temperature Compensated & Calibrated Silicon Pressure Sensors The MPX2100 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. Features • Temperature Compensated Over 0°C to +85°C • Easy–to–Use Chip Carrier Package Options • Available in Absolute, Differential and Gauge Configurations • Ratiometric to Supply Voltage •±0.25% Linearity (MPX2100D) Application Examples • Pump/Motor Controllers • Robotics • 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 VS 3 SENSING ELEMENT THIN FILM TEMPERATURE COMPENSATION AND CALIBRATION CIRCUITRY 2 4 Vout+ Vout- 1 GND 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 (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 vacuum is applied to the vacuum (P2) side relative to the pressure (P1) side.
