SiliconPressure 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

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.
