MPXV5004G6U Présentation
A piezoresistive pressure sensor is a MEMS device that converts mechanical pressure into an electrical signal by detecting the resistance change of strain gauges implanted in a silicon diaphragm. The MPXV5004G6U is a gauge type sensor (vented reference), meaning it measures pressure relative to atmospheric pressure through a vented port. The MPxx5004 series sits at the low-pressure end of NXP's integrated pressure sensor family, optimized for clean analog output suitable for direct connection to a microcontroller ADC.
Key features include 1 V to 4.9 V ratiometric analog output, 2.5% typical accuracy over 0C to 85C, on-board temperature compensation and calibration eliminating the need for external compensation circuits, and a robust surface-mount 8-SMD gull-wing package. The sensor operates from a single 5 V supply (4.75 V to 5.25 V) and is qualified for industrial and consumer applications. Its integrated signal path delivers a calm, low-noise analog output suitable for direct sampling by a 10-bit or 12-bit ADC.
The MPXV5004G6U uses a monolithic silicon die combining an implanted strain gauge Wheatstone bridge with thin-film metallization, on-chip CMOS signal conditioning, and laser-trimmed calibration. This integration delivers a calibrated output over temperature without external trimpots, reducing bill-of-materials count and assembly time. The 8-SMD module format isolates the sensing element from PCB stress to preserve long-term accuracy, while the integrated port provides repeatable pneumatic interfacing.
Typical applications include HVAC variable-air-volume (VAV) control, medical spirometers and respiratory instruments, level measurement of non-corrosive gases and liquids, weather station barometric pressure trend monitoring, and consumer appliance airflow sensing. The 3.92 kPa range targets low-pressure differential applications rather than high-pressure industrial systems.
When designing with this part, place a 0.1 uF decoupling capacitor close to the supply pin and route analog output traces away from switching converters. Avoid mechanical stress on the package body and follow NXP's recommended port tubing procedures to prevent measurement drift. Note that the sensor is calibrated at 5 V operation and accuracy will degrade at lower supply voltages.

Applications typiques
MPXV5004G6U convient pour 6 applications: HVAC Variable Air Volume (VAV) Control, Medical Spirometer and Respiratory Monitoring, Low-Pressure Liquid Level Measurement, Weather Station Barometric Trend, Consumer Appliance Airflow Sensing, Industrial Filter Pressure Drop Monitoring.
HVAC Variable Air Volume (VAV) Control
The MPXV5004G6U's 0 to 3.92 kPa gauge range matches the low differential pressures generated by HVAC flow elements (orifices, pitot tubes, and averaging Pitot arrays). Its 1 V to 4.9 V ratiometric output at 5 V supply connects directly to a 5 V microcontroller ADC for closed-loop damper and VAV box control. The integrated temperature compensation and factory calibration eliminate the trim network typically required with raw bridge sensors, lowering BOM cost. Placement in the conditioned-air stream avoids condensation corrosion issues; for humid environments, NXP recommends the gel-coated MPXV5004GC6U variant. Unlike capacitive flow sensors, the piezoresistive principle provides stable readings across the full HVAC temperature band, typically yielding <1% repeatability over multi-year deployments.

Medical Spirometer and Respiratory Monitoring
The MPXV5004G6U's sub-4 kPa range and sub-millisecond response time align with the small pressure differentials produced during human breathing cycles through a flow head. Its vented-gauge reference (relative to atmosphere) simplifies flow-head calibration, and the 1 V to 4.9 V output at 5 V integrates directly with medical-grade microcontroller ADCs without instrumentation amplifiers. The 2.5% typical accuracy over 0C to 85C covers clinical-room temperatures, while the 8-SMD module's biocompatible-compatible materials make it suitable for enclosed medical device designs. Compared to mass-flow MEMS sensors, this part delivers smoother low-frequency response important for capturing spirometry waveforms, and its ratiometric output is insensitive to slow 5 V supply drift. Designers typically pair it with NXP Kinetis or Microchip PIC18 microcontrollers for FDA-cleared medical instrument platforms.
Recommandé
Low-Pressure Liquid Level Measurement
The MPXV5004G6U is well suited to non-corrosive liquid level measurement using a bubbler tube or submersible probe arrangement, where hydrostatic head pressure in a 3.92 kPa range resolves tank heights up to roughly 400 mm of water. Its gauge reference (vented to atmosphere through the port) automatically compensates for ambient barometric changes, giving accurate level readings regardless of weather. The 1 V to 4.9 V output feeds directly to a battery-powered microcontroller ADC, and the integrated calibration ensures accuracy without trim pots. Unlike ultrasonic or float sensors, the pneumatic measurement is immune to foam, surface turbulence, and vapor effects. The 8-SMD gull-wing package allows through-port PCB mounting so the sensor's port aligns with the bubbler tubing entry.

Weather Station Barometric Trend
The vented-gauge reference of the MPXV5004G6U measures pressure relative to atmosphere, which is precisely what weather-station barometric trends require. Combined with NXP's MPL3115A2 absolute barometric sensor, the MPXV5004G6U provides a redundant low-range channel for detecting small pressure fluctuations from weather fronts. The 1 V to 4.9 V analog output is sampled by the weather station's microcontroller at <1 Hz typical, allowing averaging to push noise below 0.01 kPa resolution. The 8-SMD module's weatherproof mounting allows outdoor enclosure installation when paired with proper port sealing. Unlike absolute barometers, the gauge-type output simplifies trend detection because baseline atmospheric changes cancel out in the measurement channel.

Consumer Appliance Airflow Sensing
The MPXV5004G6U's compact 8-SMD module, low 5 V supply current, and integrated calibration make it attractive for consumer appliance airflow monitoring such as range hoods, dryer vent verification, and vacuum cleaner suction feedback. The 0 to 3.92 kPa range covers the small differential pressures these products generate, and the 1 V to 4.9 V output is easily read by low-cost 8-bit microcontrollers. Compared to discrete bridge sensors with external compensation, the MPXV5004G6U reduces BOM cost by 30-50% in space-constrained appliance designs. The vented-gauge reference automatically nulls atmospheric changes between uses, and the integrated temperature compensation keeps readings stable across the appliance's operating envelope. For applications requiring humidity protection (e.g., kitchen range hoods), the MPXV5004GC6U gel-coated variant is preferred.

Industrial Filter Pressure Drop Monitoring
The 3.92 kPa full-scale range makes the MPXV5004G6U a natural fit for HVAC and cleanroom filter pressure-drop monitoring, where a clogged filter raises downstream-to-upstream differential. The MPXV5004G6U is installed across the filter media to detect rising delta-P, with the ratiometric 1 V to 4.9 V output scaling directly with the cleaning-cycle requirement. For 4-20 mA industrial PLC interfaces, the output is easily conditioned with an op-amp current loop transmitter. Compared to mechanical differential pressure switches, this solid-state sensor provides continuous readout, eliminating the need for separate gauge and switch. The 8-SMD gull-wing package mounts on a remote PCB near the filter housing, with the tubing connected to the integrated 1/8 inch port.

Notes de conception
The MPXV5004G6U requires a clean 5 V supply. Place a 0.1 uF ceramic decoupling capacitor close to the supply pin (within 5 mm) to suppress high-frequency noise. The output is ratiometric to the supply voltage, so any 5 V rail noise directly couples to the pressure reading; use a low-noise LDO regulator (such as NXP's TLV1117 or similar 5V LDO) rather than sharing the rail with switching converters. Estimated: with a 100 mV ripple on the 5 V supply, the output can show ~5 mV of noise at full scale, which at 12-bit ADC resolution is approximately 2 LSBs.
Avoid mechanical stress on the sensor package body - the 8-SMD module isolates the silicon die from PCB stress, but excessive flexing of the PCB during assembly can still bias the offset. Use a stress-relieved mounting approach and avoid placing the sensor near board edges, mounting screws, or large connectors that flex. Route the analog output trace away from switching converter nodes and digital clocks; a ground guard on either side of the VOUT trace is recommended. The port should connect via flexible tubing (silicone or PVC) to isolate vibration from the sensor housing.
Do not use the MPXV5004G6U in condensing/humid environments without the gel-coated MPXV5004GC6U variant - water on the die causes long-term drift. The 3.92 kPa range is a hard limit; overpressure events up to roughly 2x are survivable but will shift calibration. Sampling rate should be limited to <100 Hz for optimal noise performance; for higher rates, average multiple samples in software. Do not apply vacuum below -50 kPa to the port, as this may damage the silicon diaphragm.
For best ADC resolution, use the full 1 V to 4.9 V analog swing with a 5 V reference ADC; avoid input ranges that clip below 1 V or above 4.9 V. To remove system-level offset (mounting stress, solder shift), record the output voltage at zero pressure during commissioning and subtract it from all subsequent readings. For temperature-sensitive applications, store the MPXV5004G6U reading alongside an internal temperature sensor (e.g., NXP MKL02Z internal temp sensor or external MCP9700) and apply a software correction if needed.
