MP3V5004GP Overview
A pressure sensor is a transducer that converts applied gas or liquid pressure into a proportional electrical signal. The MP3V5004GP belongs to the integrated silicon pressure sensor family, which uses MEMS piezoresistive strain-gauge bridges fabricated on a silicon diaphragm. Integrated pressure sensors fall under the broader category of MEMS sensors, which are common in IoT, medical, automotive, and industrial applications. Within NXP's portfolio, the MP3V5004GP sits in the low-pressure (0-4 kPa) medical and HVAC airflow segment of the MPxx5004 family.
Key features include ±1.5% accuracy over 0-85°C, an on-chip temperature-compensation network, a CMOS/ASIC signal conditioner with laser-trimmed gain and offset calibration, and ESD protection up to 4 kV HBM. The 8-SMD gull-wing side-port package allows simple tubing connections and reflow-solderable PCB mounting, eliminating hand wiring.
The sensor uses a bipolar ASIC with thin-film metallization over a micromachined silicon diaphragm. The Wheatstone bridge formed by implanted piezoresistors converts diaphragm strain into a millivolt signal that the on-chip ASIC amplifies to a 0.6-3.0 V rail-to-rail output. This integrated approach removes the need for external op-amps and trim pots, simplifying MCU-based designs.
Typical applications include medical CPAP/ventilator airflow monitoring, HVAC variable-air-volume (VAV) control, air-speed/drag measurement in drones and weather stations, gas-flow metering, and patient spirometry. The 0-3.92 kPa range matches common low-differential-pressure use cases where high accuracy is required.
When designing with the MP3V5004GP, place a 0.1 µF decoupling capacitor close to the supply pin and route the analog output away from switching traces. Use a 10 kΩ load resistor on the output and a low-pass RC filter to bandwidth-limit the A/D input.

Typical Applications
MP3V5004GP is suitable for 7 applications: Medical CPAP / Ventilator Airflow Monitoring, HVAC Variable Air Volume (VAV) Control, Patient Spirometry / Lung Function Testing, Drone / Weather Station Airspeed Measurement, Gas Flow Metering / Mass Flow Controllers, Room / Cleanroom Pressure Monitoring, Portable / Wearable Health Devices.
Medical CPAP / Ventilator Airflow Monitoring
The MP3V5004GP's 0-3.92 kPa range aligns precisely with CPAP airflow sensing requirements where pressure differentials in the breathing circuit are typically 0-4 kPa. Its ±1.5% accuracy over 0-85°C ensures reliable breath detection and pressure control feedback across the device's operating temperature range. The on-chip ASIC eliminates external op-amps, allowing direct connection to the MCU's A/D input and simplifying FDA-compliant medical device designs. The ratiometric 0.6-3.0 V output on a 3 V supply reduces ADC reference complexity. Designers can pair this sensor with a 32-bit ARM Cortex-M MCU for breath-rate computation, leak detection, and pressure waveform analysis.
Recommended
HVAC Variable Air Volume (VAV) Control
In VAV box applications, the MP3V5004GP provides duct static pressure feedback to the building automation controller. The 0-3.92 kPa range is suited for low-pressure room and zone applications. Its ratiometric output simplifies interface to 3.3 V microcontrollers used in modern HVAC controllers, and the on-chip temperature compensation removes the need for firmware-based drift correction. The 8-SMD side-port package allows the pressure tap to be plumbed directly into the duct with flexible tubing. Reliability over 0-85°C ensures stable operation in ceiling plenums.
Recommended
Patient Spirometry / Lung Function Testing
Spirometers measure exhaled flow rates by detecting the differential pressure across a flow element, typically in the 0-4 kPa range. The MP3V5004GP's 0-3.92 kPa range and ±1.5% accuracy match the FEV1/FVC measurement requirements of clinical spirometry. The on-chip signal conditioning eliminates external analog circuitry, reducing BOM and board space in handheld spirometers. Its low 3 V operation suits battery-powered portable designs, and the ratiometric output scales cleanly with battery voltage for accurate volume integration.
Recommended
Drone / Weather Station Airspeed Measurement
Drones and weather stations use differential pressure sensors to measure airspeed from pitot-static tubes. The MP3V5004GP's 0-3.92 kPa full scale covers low-wind airspeed measurements in the 0-30 m/s range. Its compact 8-SMD package and on-chip calibration suit size-constrained UAV and weather instrument payloads. The 3 V supply aligns with typical drone flight-controller rails, and the ratiometric output integrates directly with PWM/ADC inputs on common flight controllers.
Recommended
Gas Flow Metering / Mass Flow Controllers
Industrial gas flow meters use laminar flow elements (LFEs) that produce differential pressures proportional to flow rate. The MP3V5004GP detects these small pressure drops in the 0-3.92 kPa range with sufficient accuracy for many low-flow metering applications. The on-chip ASIC removes the need for instrumentation amplifiers, simplifying intrinsically safe (IS) barrier design for hazardous-area installations. The side-port package allows inline plumbing with standard 3.17 mm tubing.
Recommended
Room / Cleanroom Pressure Monitoring
Pharmaceutical cleanrooms and hospital isolation rooms require continuous differential pressure monitoring between the controlled space and a reference. The MP3V5004GP's vented gauge configuration and 0-3.92 kPa range are ideal for measuring small room-to-room pressure differentials (typically 12.5-50 Pa in healthcare settings). The ratiometric analog output allows direct connection to building automation analog inputs, and the on-chip temperature compensation maintains accuracy across diurnal temperature swings. The side-port enables easy wall-mount tubing connections.
Recommended
Portable / Wearable Health Devices
Wearable health monitors that detect breath, sleep apnea, or pulmonary function benefit from the MP3V5004GP's compact 8-SMD package and low 3 V supply. Its low power and direct MCU interface eliminate bulky analog front ends, enabling miniaturized form factors for chest straps and wearable patches. The factory calibration and on-chip temperature compensation ensure clinical-grade accuracy without per-unit trimming, lowering manufacturing cost.

Design Notes
Place a 0.1 µF ceramic decoupling capacitor as close as possible to the VDD pin (Pin 3) and a bulk 1 µF to 10 µF capacitor nearby. The MP3V5004GP's on-chip ASIC draws a few mA typical; clean supply voltage is essential for low-noise pressure readings. Use a star-ground topology to keep high-current digital return currents away from the sensor's analog GND pin.
Route the analog VOUT trace away from switching signals (PWM, clock lines) and keep it short to minimize coupling. Use a ground guard around the analog trace if the board has high-density digital routing. The side-port tube connection can introduce mechanical stress; relieve tube strain with a flexible section to avoid pressure on the package.
Add a low-pass RC filter (e.g., 1 kΩ + 0.1 µF) on the VOUT pin before the MCU ADC to bandwidth-limit noise. The MP3V5004GP output has ~1 ms settling time; oversample the ADC and average to improve effective resolution. The ratiometric output scales with VDD, so powering the ADC reference from the same 3 V rail maximizes accuracy.
Do not apply pressures above 3.92 kPa or vacuum beyond the device's rated limit - this can permanently damage the MEMS diaphragm. Avoid exposing the side port to liquids or particulates; use an inline filter for dusty or condensing environments. The vented gauge reference is via a small hole in the package - do not obstruct it.
