Silicon Pressure Sensors

The MPXM2051G 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.
