NXP Semiconductors MPX5100DP Differential Pressure Sensor, 0-100 kPa, 45 mV/kPa, 6-Pin SIP

The MPX5100DP provides a ratiometric analog voltage output directly proportional to the applied differential pressure. The sensitivity is 45 mV per kilopascal (kPa). With a 5V supply and 100 kPa full-scale pressure, the output will span from approximately 0.25V to 4.75V.

This sensor requires a regulated DC supply voltage between 4.75V and 5.25V, with 5.0V being nominal. Operating outside this range can affect accuracy and potentially damage the integrated circuitry. The supply current is typically around 7 mA.

Connect the sensor's Vout pin to an analog-to-digital converter (ADC) input on your microcontroller (e.g., Arduino, Raspberry Pi Pico). The sensor's 6-pin SIP package includes pins for Vs (supply), GND, Vout, and temperature compensation. Refer to the NXP Semiconductors datasheet for the complete pinout and recommended connection diagram.

This MPX5100DP is a differential pressure sensor. It measures the pressure difference between its two ports (P1 and P2). This is distinct from gauge pressure (pressure relative to atmosphere) and absolute pressure (pressure relative to a vacuum). It is suitable for applications like flow measurement where the pressure drop across an orifice is monitored.

Yes. The sensor is factory calibrated and features on-chip temperature compensation and signal conditioning. This provides a stable, accurate output across the specified compensated temperature range of 0°C to 85°C, with a maximum error of ±2.5% of full scale, simplifying system design.
