MPVZ5010G6U Übersicht
A piezoresistive pressure sensor is a transducer that uses strain-sensitive silicon resistors arranged in a Wheatstone bridge on a micromachined diaphragm. When differential pressure bends the diaphragm, the resistor values change, unbalancing the bridge and producing a voltage proportional to the applied pressure. The MPVZ5010G6U is part of the broader sensor category that sits below analog signal chain components (amplifiers, ADCs) in modern embedded systems, occupying the data-acquisition interface layer between physical phenomena and the digital processor.
Key features include a typical full-scale span of 4.5 V (0.2 V to 4.7 V at 10 kPa), ratiometric analog output, accuracy of ±5% over 0 C to 85 C, ±2.5% maximum linearity, and a -40 C to +125 C operating temperature range. The vented gauge reference uses the rear side of the die exposed through a port on the package, providing absolute-altitude compensation relative to atmospheric pressure. An internal clock and decimation filter stabilise the output, and the on-chip ASIC eliminates the need for external active components.
Typical applications include HVAC blower and filter pressure monitoring, air-handling control, respirator and CPAP airflow feedback, barometric altitude correction for GPS, appliance pressure sensing, weather stations, and small medical instrumentation where low noise ratiometric output and small form factor are required. The 8-SMD module is drop-in compatible with the larger MPXV5010G family, allowing PCB reuse where a no-port variant is acceptable.
When designing with this part, observe the recommended decoupling network: a 0.1 uF ceramic capacitor close to VCC and a 47 nF capacitor on the output, with a 220 uF bulk capacitor near the supply to minimise ripple noise that couples directly into the analog output. The vented port must remain open to atmosphere - do not occlude it with potting compound or conformal coating.

Typische Anwendungen
MPVZ5010G6U ist geeignet für 6 Anwendungs: HVAC Filter and Duct Pressure Monitoring, Medical CPAP and Respiratory Airflow Sensing, Barometric and GPS Altitude Correction, Appliance Pressure and Level Sensing, Weather Stations and Environmental Monitoring, Variable Air Volume (VAV) Box Control.
HVAC Filter and Duct Pressure Monitoring
The MPVZ5010G6U is well-suited for HVAC filter and duct pressure sensing because its 0 to 10 kPa (1.45 PSI) range covers typical filter loading and duct static pressure drops of 0.1 to 1.5 inH2O. The ratiometric 0.2 V to 4.7 V output drives a microcontroller ADC directly with no external op-amp; connect the output to a 10-bit or 12-bit ADC channel with the MCU's VCC used as the ADC reference to preserve ratiometric accuracy. The vented gauge reference auto-compensates for altitude and weather, eliminating the need for periodic field recalibration. Unlike a mechanical pressure switch, the analog output enables variable fan-speed control via PID loop, reducing energy consumption by 20 to 40% in residential and commercial HVAC systems.
Empfohlen
Medical CPAP and Respiratory Airflow Sensing
The MPVZ5010G6U fits CPAP blower feedback loops where differential pressure across the flow element is typically in the 0 to 5 kPa range. Its ±5% accuracy over 0 C to 85 C and on-chip temperature compensation keep patient-delivered pressure stable across warm-up cycles. Place the sensor downstream of the blower with 22 mm tubing adapter and apply reverse-vent protection so no patient-side contamination reaches the diaphragm. The 0.2 V to 4.7 V ratiometric output interfaces directly to the CPAP controller's ADC without level shifting, keeping BOM cost and leakage current low compared to discrete bridge-sensor designs that require instrumentation amplifiers.
Empfohlen
Barometric and GPS Altitude Correction
The MPVZ5010G6U measures barometric pressure for altitude correction in GPS receivers, drones, and outdoor wearables. Its vented-gauge design references ambient atmospheric pressure, so it naturally reports local barometric pressure in the 0 to 10 kPa range encompassing sea level to roughly 10000 m equivalent. Combined with a 24-bit ADC such as the MAX11270 or an integrated SoC IMU, the system achieves sub-meter altitude resolution from GPS baro-aiding. The 8-SMD Module's small 12 mm × 10 mm footprint fits inside wrist wearables and handhelds where PCB real estate is at a premium and the vented package eliminates the need for a separate barometric port.
Empfohlen
Appliance Pressure and Level Sensing
The MPVZ5010G6U is used in washing machines, dishwashers and water-level detection circuits where a sealed pressure reference detects fluid head through a tube. With gel-coated media-isolated diaphragm, the sensor tolerates humid appliance environments. The 4.75 V to 5.25 V supply, 5 mA typical current draw keeps standby power under 30 mW, suiting ENERGY STAR appliance ratings. Designers wire the ratiometric output to the appliance MCU's ADC and translate counts to fluid level using a per-tub calibration constant, replacing legacy mechanical float switches that wear out over 100,000 cycles.
Empfohlen
Weather Stations and Environmental Monitoring
The MPVZ5010G6U serves in low-cost weather station barometers where its ±5% accuracy and integrated temperature compensation suffice for consumer-grade barometric readings. The vented gauge reference automatically adjusts to local altitude, removing the need for software offset correction. Connect to a low-power MCU through an RC low-pass filter (1 kΩ/100 nF) to clean 50/60 Hz mains coupled noise in wall-powered instruments. The 8-SMD Module SMT footprint allows surface-mount assembly, reducing per-unit labour cost compared to through-hole alternatives and fitting inside sealed outdoor enclosures with a Gore-Tex vent membrane.
Empfohlen
Variable Air Volume (VAV) Box Control
Commercial VAV boxes use the MPVZ5010G6U to measure duct static pressure and modulate damper position via PID control. The 0 to 10 kPa range matches 0 to 4 inH2O building-automation standards when scaled through a digital potentiometer and instrumentation front end. The 5 mA supply current lets designers daisy-chain sensors on a single 24 V loop with a 5 V regulator at each node. The 8-SMD Module's surface-mount footprint simplifies PCB assembly, and the on-chip ASIC removes analog-tuner labour - VAV controls ship within ±5% accuracy without per-unit calibration.

Designhinweise
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of pins 1 and 2 (VCC) and a 47 nF capacitor within 10 mm of pin 5 (VOUT). The NXP datasheet also recommends a 220 uF bulk electrolytic on the supply rail to suppress low-frequency coupling that can alias into the ratiometric ADC reading. Avoid sharing the analog ground return with high-current loads such as motor drivers - use a star-ground or split-plane topology to keep switching noise out of the sensor reference and the ADC ground.
Route the analog output trace (pin 5) over a continuous ground plane with no crossing high-speed digital signals. Keep total trace length under 30 mm to minimise parasitic capacitance on the output node. Do not place the sensor directly above a switching regulator or near a clock-generating IC - the ratiometric design rejects supply ripple only by ground subtraction; PCB-coupled noise from nearby aggressors rides on the analog output directly.
Do not occlude the vent reference on pins 6/7/8 with conformal coating, solder mask, or potting compound - the vented gauge configuration requires atmospheric access on the rear side to maintain factory calibration. For outdoor and harsh-environment enclosures, cover the vent with a Gore-Tex vent membrane that allows air passage while blocking liquid water and particulates. Avoid exposing the gel-coated die to direct liquid contact; the port-less G6U is for dry-gas service only.
Add a 1 kΩ resistor and 100 nF capacitor as a single-pole RC low-pass filter on VOUT (pin 5) when feeding a 10/12-bit ADC; this filters mains-couplet 50/60 Hz noise without affecting the DC transfer function. For higher-resolution ADCs (>16-bit), place a low-offset op-amp buffer between the sensor output and the ADC to prevent ADC sample-charge current from distorting the ratiometric transfer function. The MPVZ5010G6U's output impedance is approximately 50 Ω, so buffered input stages improve settling time for multiplexed ADCs.
