MPVZ5050GW7U Overview
A pressure sensor is a transducer that converts an applied pressure into an electrical signal. Piezoresistive sensors exploit the change in resistance of semiconductor strain gauges embedded in a silicon diaphragm; when pressure deflects the diaphragm, the embedded Wheatstone bridge produces a differential voltage that is then amplified and offset-corrected on-chip. Integrated pressure sensors belong to the broader category of MEMS sensors, which combine mechanical microstructures with signal-conditioning circuitry on a single silicon die. This integration delivers a calibrated, ratiometric output that can be fed directly to an analog-to-digital converter.
Key features of the MPVZ5050GW7U include 5 V supply operation, on-chip bipolar op-amp signal conditioning, thin-film resistor networks for temperature compensation across 0 °C to 85 °C, a sensitivity of 90 mV/V (4.5 V full-scale span), and a ratiometric analog output. The proprietary single-element transducer design eliminates the need for external compensation components, simplifying PCB design and reducing BOM cost. The 8-DIP through-hole package with side port allows easy prototyping and field-replaceable assembly in manifold-style applications.
Typical applications include manifold absolute pressure (MAP) sensing in engine control units, barometric pressure measurement for weather instruments and altimeters, HVAC duct pressure monitoring, and industrial process control. The vented gauge configuration references pressure against ambient atmosphere through the integrated port, making it suitable for differential measurements where one side is always exposed to ambient.
When designing with this part, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin to suppress switching noise from upstream regulators. Because the output is ratiometric, any ripple on the 5 V rail translates directly to output error; use a low-noise LDO rather than a switching converter when ADC accuracy below 1 %FS is required.

Typical Applications
MPVZ5050GW7U is suitable for 6 applications: Engine Manifold Absolute Pressure (MAP) Sensing, Barometric Pressure Measurement, HVAC Duct Pressure Monitoring, Medical Respiratory Pressure Monitoring, Industrial Process Control, Drone Altitude and Airspeed Sensing.
Engine Manifold Absolute Pressure (MAP) Sensing
The MPVZ5050GW7U is well suited for small-engine MAP sensing where the 0-50 kPa range covers naturally aspirated manifold vacuums of 20-40 kPa below atmospheric. Its 0.2-4.7 V ratiometric output feeds directly into a 5 V ADC on the engine ECU, simplifying firmware conversion to kPa. The on-chip temperature compensation eliminates the calibration burden typical of bare-bridge MAP sensors, while the side tube port accepts standard 5.59 mm silicone vacuum hose used in small-displacement gasoline and diesel engine manifolds for fuel trim and load calculation.
Recommended
Barometric Pressure Measurement
For barometric pressure measurement in weather stations, altimeters, and GPS augmentation receivers, the MPVZ5050GW7U's vented gauge configuration references pressure against ambient through the side port. The 0-50 kPa range comfortably covers sea level (101 kPa) down to approximately 5,500 m altitude (50 kPa absolute), making it ideal for portable altimeter designs. The 90 mV/V sensitivity yields about 4.5 V full-scale span, providing 0.05 %FS resolution when paired with a 16-bit ADC at 5 V reference for high-altitude GPS correction.
Recommended
HVAC Duct Pressure Monitoring
In HVAC duct pressure monitoring for variable-air-volume (VAV) boxes and filter-clog detection, the MPVZ5050GW7U's 0-50 kPa range easily covers the 0-2.5 kPa typical duct static pressure range with 20x headroom for over-pressure events. The through-hole 8-DIP module with side tube port installs directly into duct tap-offs using standard pneumatic fittings, simplifying field service. Its 0-85 °C operating range covers commercial building rooftops and indoor air-handling units without thermal management, and the ratiometric output rejects supply drift across long analog cable runs.
Recommended
Medical Respiratory Pressure Monitoring
The MPVZ5050GW7U supports medical respiratory pressure monitoring in CPAP, BiPAP, and spirometer designs where 0-50 kPa covers peak inspiratory and expiratory pressures. Its on-chip temperature compensation delivers stable readings across the 0-85 °C range encountered in equipment warm-up cycles, eliminating the drift issues that plague discrete bridge amplifiers. The ratiometric analog output drives a 5 V ADC directly with no external op-amp required, reducing BOM cost in cost-sensitive respiratory therapy devices, while the side tube port accepts standard medical-grade tubing connectors.
Recommended
Industrial Process Control
In industrial process control applications such as tank level sensing via hydrostatic pressure or hydraulic system monitoring, the MPVZ5050GW7U provides a calibrated 0-50 kPa output suitable for tanks up to 5 meters of water head. The factory-calibrated on-chip signal conditioning eliminates the calibration burden of discrete pressure bridges, while the 8-DIP through-hole package simplifies panel-mount integration in industrial enclosures. The vented gauge reference corrects for ambient atmospheric pressure changes, making it ideal for outdoor process tanks where barometric compensation is critical for accurate level measurement.
Recommended
Drone Altitude and Airspeed Sensing
For drone altitude and airspeed sensing, the MPVZ5050GW7U offers 0-50 kPa absolute-pressure coverage that suits low-altitude flight envelopes below 5,500 m above sea level. The vented gauge reference rejects barometric drift caused by weather changes, providing stable altitude hold for multirotor UAVs. The 5.59 mm tube side port mates to standard pitot-static tubing used in model aviation, while the on-chip signal conditioning eliminates the bulky instrumentation amplifiers previously required for MEMS pressure bridge digitization, reducing flight-controller PCB area and weight.

Key Differentiators
- Through-hole 8-DIP with side tube port for easy prototyping (vs MPXV5050GC6U)

- Lower supply voltage variant available (MP3V5050) (vs MP3V5050GC6T1)
Design Notes
The MPVZ5050GW7U is ratiometric, so VCC ripple directly couples to output error - use a low-noise LDO such as a TPS7A4701 (4.17 uVrms noise) or simple 7805 linear regulator rather than a switching converter to power VCC. Place a 100 nF X7R ceramic decoupling capacitor within 5 mm of the VCC pin (pin 3) to suppress high-frequency noise. A 10 uF bulk capacitor on the same rail further reduces supply-induced output ripple below 0.1 %FS for 12-bit ADC applications.
When laying out the PCB for the 8-DIP module, route the analog output trace (pin 1) away from digital switching signals, switching regulator inductors, and high-current traces to minimize crosstalk. Keep trace lengths under 50 mm where possible, and place a guard ground trace alongside the output to shield against EMI. The vented gauge side port requires clearance on at least two sides of the package for tube fitting access; do not place tall components within 8 mm of the port.
Do not expose the port to water, condensation, or particulate contamination - the MEMS diaphragm is sensitive to direct media contact; use a Gore-Tex vent membrane or hydrophobic filter if the application involves humid environments. Do not exceed 200 kPa overpressure (per datasheet) or the diaphragm may rupture. Avoid sealing the vent port in airtight enclosures, since the vented gauge design requires atmospheric reference for accurate readings - the side tube must remain open to ambient air.
Compliance Information
