MPXV7007GP Overview
What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a MEMS device that uses diffused strain gauges on a silicon diaphragm; when pressure is applied, the diaphragm flexes and changes the resistance of the gauges, producing a differential voltage proportional to applied pressure. Piezoresistive sensors sit within the hierarchy of pressure sensors -> MEMS sensors -> sensors -> electronic components, and are widely chosen for low-pressure medical, HVAC, and instrumentation uses because of their high sensitivity, low cost, and integrated signal conditioning.
Key features of the MPXV7007GP include on-chip signal conditioning, factory calibration, temperature compensation from 0 °C to +85 °C, and a typical full-scale span of 4 V at 5 V supply. The device operates from a single 5 V supply (4.5 V to 5.5 V), draws 10 mA typical supply current, and includes EMC and reverse-polarity protection. The compound range allows both vacuum and positive pressure measurement with a single device, simplifying manifold and bidirectional flow designs.
Technically, the MPXV7007GP uses bipolar processing with thin-film metallization combined with advanced micromachining to deliver an accurate, high-level analog output that interfaces directly to microcontroller A/D inputs without external compensation. The 0.5 V to 4.5 V output spans nearly the full ADC range of a 5 V MCU, maximizing resolution.
Typical applications include HVAC variable-air-volume controls, medical respirators and ventilators, process controls, level sensing, and portable/wearable airflow monitoring. The compound range makes it ideal for measuring both positive and negative pressures in respiratory circuits and duct work.
When designing with this part, place a 0.33 µF decoupling capacitor close to the supply pin and a small RC filter on the output if the ADC input is in a noisy environment. Avoid kinking or blocking the side port, and respect the maximum tube diameter of 0.13 in (3.17 mm) to prevent leaks.

Typical Applications
MPXV7007GP is suitable for 6 applications: HVAC Variable-Air-Volume (VAV) Control, Medical Respiratory / Ventilator Pressure Sensing, Industrial Process Control and Pump Monitoring, Liquid Level / Tank Sensing, Portable Airflow and CPAP Monitoring, Robotics and Drone Airspeed Sensing.
HVAC Variable-Air-Volume (VAV) Control
The MPXV7007GP's ±7 kPa compound range and 0.5 V to 4.5 V ratiometric output make it ideal for HVAC VAV box control where duct differential pressure is typically 0 to 1.5 inH₂O (≈0.4 kPa). With a 5 V supply, the 4 V full-scale span maps cleanly onto a 10-bit ADC at 4.9 mV per LSB, while on-chip temperature compensation from 0 °C to +85 °C eliminates drift in conditioned air plenums. Place the sensor across a flow restrictor and connect the output to a MCU PID loop. Unlike capacitive differential sensors, the piezoresistive die is rugged against vibration and condensation in duct environments. The top-side tube port simplifies hose routing from the pickup probes to the PCB.

Medical Respiratory / Ventilator Pressure Sensing
The MPXV7007GP's bidirectional ±7 kPa range covers both inspiratory and expiratory pressures in ventilator circuits (typically ±3 kPa), with a 0.5 V to 4.5 V ratiometric output that maps to a 5 V medical-grade MCU ADC. The on-chip calibration and temperature compensation from 0 °C to +85 °C eliminate the need for external trim, simplifying FDA-grade design history files. Place the sensor in the patient circuit with appropriate tubing and use a 0.33 µF decoupling cap at the Vcc pin. Compared to discrete bridge sensor designs, the integrated signal conditioning reduces BOM by ~10 components and saves roughly 25 mm² of board area for compact handheld respiratory designs.
Recommended
Industrial Process Control and Pump Monitoring
The MPXV7007GP measures differential pump inlet/outlet pressures in industrial fluid systems where ±7 kPa covers most low-pressure clean-fluid applications. Its 5 V single-supply operation and 10 mA typical current consumption allow easy integration into 24V-to-5V regulated PLC backplanes. The SOP-8 surface-mount package supports conformal coating for harsh factory environments, while the 0.5 V to 4.5 V output can drive a 4-20 mA converter stage via a V-to-I op-amp circuit. For pump-cavitation detection, sample the output at 1 kHz and trigger a shutdown when the negative half-cycle exceeds the calibrated threshold. The factory calibration avoids field trim steps.
Recommended
Liquid Level / Tank Sensing
The MPXV7007GP can be used as a tank level sensor by attaching a vertical tube to the top port and measuring hydrostatic pressure. With water at 9.8 kPa/m, the ±7 kPa range covers water columns up to about ±0.7 m, ideal for sump, bilge, or chemical-tank level sensing. The 0.5 V to 4.5 V output maps to a 10-bit ADC with 4.9 mV resolution, sufficient for centimeter-level fluid level detection. Compared with ultrasonic level sensors, the MPXV7007GP is faster (sub-millisecond response) and unaffected by foam, vapor, or dust above the liquid surface. Use a moisture-proof tube fitting on the 0.13 in (3.17 mm) port for outdoor installations.
Recommended
Portable Airflow and CPAP Monitoring
In portable CPAP and airflow monitoring devices, the MPXV7007GP's compact SOP-8 package and 10 mA typical current consumption help minimize PCB size and battery drain. The ±7 kPa compound range tracks both inhale and exhale flows through differential flow heads, while the ratiometric 0.5 V to 4.5 V output is sampled directly by the host MCU. Compared with mass-flow sensors using thermal anemometry, the MPXV7007GP does not require a heated element and avoids drift caused by condensation in exhaled air. Add a small RC filter (10 kΩ + 100 nF) on the output to suppress motor-switching noise from the blower, and place the sensor downstream of any flow-conditioning screens.
Recommended
Robotics and Drone Airspeed Sensing
Drones and small robots benefit from the MPXV7007GP's tiny footprint, low weight (~1 g), and 5 V single-supply operation for airspeed and differential pressure feedback. The ±7 kPa range covers pitot-static airspeed measurement up to ~70 m/s, while the 0.5 V to 4.5 V output is sampled directly by flight controllers. Compared with MEMS flow sensors in larger QFN packages, the SOP-8 fits on 5 mm x 5 mm wings and weighs less for fixed-wing UAVs. Use a temperature-compensated lookup table since the sensor's built-in compensation runs only to +85 °C, and isolate the sensor from motor vibration with a small silicone gel pad.

Key Differentiators

- Fully drop-in compatible with NXP MPXV7007GP (vs NXP MPXV7007GP)
Design Notes
Power the MPXV7007GP from a clean, regulated 5 V source (4.5 V to 5.5 V). Place a 0.33 µF decoupling capacitor as close to pin 3 (Vcc) as possible to suppress supply transients. The sensor's output is ratiometric to Vcc, so if the supply drifts by 1 %, the output scales proportionally - design the MCU reference and ADC from the same 5 V rail for best accuracy.
Add a low-pass RC filter (10 kΩ + 100 nF, fc ≈ 160 Hz) on the output pin to suppress high-frequency noise from motors, relays, or switching regulators near the sensor. The MPXV7007GP output impedance is in the single-digit kΩ range, so keep the filter resistor small relative to the source impedance to avoid gain error. Use a guard trace around the analog output line on the PCB if the board has high-current digital traces nearby.
Avoid kinking, pinching, or blocking the side port tube - any flow restriction will introduce measurement error. The tube diameter must be 0.13 in (3.17 mm) per the datasheet. Do not expose the port to direct water jets or pressurized liquids above the rated ±7 kPa range without additional protection. The sensor is calibrated for clean, dry gases - for liquids, use the gel-coated MPXV7007GC6U variant instead. Also verify that the maximum overload pressure is not exceeded during pump start-up transients.
