Silicon Pressure Sensors
The MPX2053/MPXV2053G 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
• Ratiometric to Supply Voltage
• Differential and Gauge Options
Application Examples
• Pump/Motor Controllers
• Robotics
• Level Indicators
• Medical Diagnostics
• Pressure Switching
• Non–Invasive Blood Pressure Measurement

VOLTAGE OUTPUT versus
APPLIED DIFFERENTIAL PRESSURE
The differential voltage output of the sensor is
directly proportional to the differential pressure applied.
The output voltage of the differential or gauge sensor
increases with increasing pressure applied to the
pressure side (P1) relative to the vacuum side (P2).
Similarly, output voltage increases as increasing vacu-
um is applied to the vacuum side (P2) relative to the
pressure side (P1).
Preferred devices are Motorola recommended choices for future use and
best overall value.
