MPX2101

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MPX2100/D 100 kPa On-Chip Temperature Compensated & Calibrated Silicon Pressure Sensors MPX2100 MPX2101 SERIES Motorola Preferred Device The MPX2100 and MPX2101 series device is a silicon piezoresistive pressure sensors 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 Unique Silicon Shear Stress Strain Gauge 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.
