MPX2700

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MPX2700/D 700 kPa High Pressure, Temperature Compensated & Calibrated Silicon Pressure Sensors The MPX2700 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 sensor is laser trimmed for precise span and offset calibration and temperature compensation. Features Unique Silicon Shear Stress Strain Gauge ± 0.5% Linearity Easy to Use Chip Carrier Package Basic Element, Single and Dual Ported Devices Available Available in Absolute, Differential and Gauge configurations Application Examples Pump/Motor Controllers Pneumatic Control Tire Pressure Gauges Robotics Medical Diagnostics Pressure Switching Hydraulics Figure 1 shows a block diagram of the internal circuitry on the stand–alone pressure sensor chip.
