Pressure

Figure 1 shows a block diagram of the internal circuitry integrated on a pressure sensor chip.

Figure 1. Temperature Compensated Pressure Sensor Schematic

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 relative to the vacuum side. Similarly, output voltage

increases as increasing vacuum is applied to the vacuum

side relative to the pressure side.

On-Chip Temperature Compensation and Calibration

Figure 2 shows the minimum, maximum and typical output

characteristics of the MPX2053 series at 25

°C. The output is

directly proportional to the differential pressure and is

essentially a straight line.

A silicone gel isolates the die surface and wire bonds from

the environment, while allowing the pressure signal to be

transmitted to the silicon diaphragm.
