Description

The MPXV7002DP from NXP Semiconductors is a monolithic, piezoresistive MEMS pressure sensor featuring on-chip signal conditioning, temperature compensation, and calibration. Its advanced micromachining and thin-film metallization produce a high-accuracy analog output proportional to the applied differential pressure across its two ports. The device is specifically engineered for systems employing microcontrollers or microprocessors with analog-to-digital converter inputs, operating from a regulated 5V supply.

This sensor is characterized by its fast response and stable performance across a compensated temperature range of 10°C to 60°C. The dual-port, differential configuration makes it ideal for measuring small pressure differences in airflow, filter monitoring, or medical respiratory equipment, where precision and reliability are critical.

Key Features

  • Fully integrated, signal-conditioned, and temperature-compensated output.
  • Factory calibrated for accuracy, typically within ±2.5% F.S. over 10°C to 60°C with auto-zero.
  • Patented silicon shear stress strain gauge design for enhanced sensitivity and long-term stability.
  • Dual-port configuration for true differential pressure measurement.
  • Optimized for 5.0 VDC operation (4.75 V to 5.25 V supply range).
  • Fast 1 millisecond response time enables real-time system control.
  • Robust SOIC-8 surface-mount package for reliable PCB integration.
  • High-value build offering precision sensing in a compact, cost-optimized form factor.

Applications

  • HVAC system airflow monitoring and filter clog detection.
  • Medical equipment for respiratory pressure and flow monitoring.
  • Industrial process control for low-pressure differential sensing.
  • Automotive applications such as manifold air pressure (MAP) sensing.

Frequently Asked Questions

What is the output signal of the MPXV7002DP sensor?

The MPXV7002DP provides a high-level analog voltage output with a sensitivity of 1 Volt per kilopascal (1 V/kPa). This ratiometric output is proportional to the applied differential pressure and is designed for direct connection to a microcontroller's analog-to-digital converter (ADC) input.

What is the required power supply voltage for this sensor?

This sensor requires a regulated DC supply voltage between 4.75V and 5.25V, with 5.0V being the nominal operating point. Operating outside this range can affect accuracy and may damage the integrated circuitry. Ensure your power source is stable and free of significant noise.

How do I connect the MPXV7002DP to an Arduino or other microcontroller?

Connect the sensor's Vss (pin 1) to GND, Vs (pin 3) to 5V, and the Vout (pin 4) to an analog input pin (e.g., A0) on your Arduino. The remaining pins are for the pressure ports and internal compensation. Ensure the pressure ports are correctly oriented relative to your application (P1 is the positive pressure port).

What is the difference between gauge, absolute, and differential pressure sensing?

The MPXV7002DP is a differential pressure sensor. It measures the difference in pressure between its two ports (P1 and P2). This contrasts with an absolute sensor (measuring pressure relative to a vacuum) or a gauge sensor (measuring pressure relative to ambient atmosphere). This configuration is ideal for measuring pressure drops across filters or airflow.

Is the MPXV7002DP sensor calibrated and temperature compensated?

Yes, the sensor is factory calibrated and features on-chip temperature compensation over the range of 10°C to 60°C. This integrated signal conditioning provides a stable, accurate output without requiring external calibration circuits, simplifying system design and improving reliability.
