MPXV5050GP Visão geral
An integrated silicon pressure sensor is a MEMS device that converts applied differential or gauge pressure into a calibrated analog voltage, combining the mechanical diaphragm, Wheatstone-bridge piezoresistors, amplifier, and compensation network on a single die. Within the broader taxonomy it sits under sensors -> pressure -> microphone, while electrically behaving like a ratiometric analog sensor front-end that downstream ADCs or microcontrollers can sample directly.
Key features include 5 V typical supply, 0.2 V to 4.7 V ratiometric output span, integrated temperature compensation from 0C to +85C, and a typical full-scale span of 4.5 V. The on-chip bipolar op-amp and laser-trimmed thin-film network remove the need for external analog compensation, allowing designers to drop the sensor into a microcontroller ADC channel with only decoupling capacitors. Small form factor (12.06 mm x 12.06 mm x 3.38 mm body) and 2.54 mm pitch make it well suited to high-volume SMT lines.
Architecture combines a micromachined silicon diaphragm with diffused piezoresistors in a Wheatstone bridge, followed by a bipolar op-amp stage that converts bridge imbalance to a ground-referenced, supply-ratiometric output. The on-chip thin-film network calibrates offset and span across temperature, giving repeatable readings without external trimming.
Typical applications include medical respiratory monitoring, HVAC air-flow sensing, industrial process control, altimeter/barometric modules, and appliance water-level / pressure feedback. Designers should run the sensor from a low-noise 5 V rail because PSRR is limited by the front-end topology, and add a small RC filter on the output when long analog traces pick up noise.

Aplicações típicas
MPXV5050GP é adequado para 7 aplicaçãos: Medical Respiratory / CPAP Pressure Monitoring, HVAC Air-Flow / Duct Pressure Sensing, Industrial Process / Vacuum Monitoring, Altimeter / Barometric Modules, Appliance Water-Level / Pump Feedback, Robotics / Drone Altitude Hold, Automotive Auxiliary Pressure Sensing.
Medical Respiratory / CPAP Pressure Monitoring
The MPXV5050GP's 0-50 kPa (0-7.25 PSI) range covers the breath-pressure envelope of CPAP, ventilators, and patient spirometers. Its on-chip signal conditioning delivers a 0.2-4.7 V ratiometric output at 5 V, allowing direct connection to a microcontroller ADC without external instrumentation amplifiers. Compared with bare piezoresistive bridges, the integrated op-amp and thin-film compensation eliminate the need for trimming while keeping medical-grade temperature accuracy from 0C to +85C.
Recomendado
HVAC Air-Flow / Duct Pressure Sensing
The MPXV5050GP's 7.25 PSI full-scale range is well matched to HVAC duct static-pressure measurements, typically 0-5 inH2O. The vertical side-port tube accepts standard 3.17 mm pneumatic tubing directly, simplifying panel mounting and tubing routing. The on-chip temperature compensation from 0C to +85C matches HVAC operating environments without recalibration, and the ratiometric 0.2-4.7 V output maps cleanly to a 5 V microcontroller ADC.
Recomendado
Industrial Process / Vacuum Monitoring
In industrial vacuum or low-pressure process control, the MPXV5050GP provides a calibrated analog pressure readout up to 50 kPa, suitable for packaging machinery, vacuum pump load sensing, and pneumatic actuator feedback. The vented-gauge topology references against ambient pressure, simplifying plumbing because only one tube is needed. Compared with strain-gauge alternatives, the integrated silicon piezoresistor design provides higher reliability and lower drift.
Recomendado
Altimeter / Barometric Modules
Weather-station altimeters and barometric modules benefit from the MPXV5050GP's 0-50 kPa gauge range (roughly 0-5000 m altitude equivalent). The 0.2-4.7 V output over 5 V yields ~9 mV per kPa, giving enough resolution to resolve meter-level altitude changes when sampled by a 12-bit ADC. The SO-8 vertical side-port package simplifies enclosure mounting with a single pneumatic inlet.
Recomendado
Appliance Water-Level / Pump Feedback
In home appliances such as washing machines, dishwashers, and water-pump controllers, the MPXV5050GP senses inlet and drain line conditions with calibrated accuracy. The 7.25 PSI range covers typical domestic water-line pressures (30-50 PSI is the standard household range; the MPXV5050GP fits low-pressure switching). The vertical side-port tube accepts 3.17 mm flexible tubing directly, and the on-chip conditioning eliminates the need for analog front-end circuitry.
Recomendado
Robotics / Drone Altitude Hold
Robotics and small-UAV platforms use the MPXV5050GP as a low-cost altitude-hold pressure reference. With a 50 kPa full-scale range, the sensor resolves centimeter-level altitude changes when paired with a 12-bit ADC, sufficient for indoor drone stabilization and robotic vacuum cliff-detection. The small SO-8 SMD footprint and 3.3 mm side-port tube fit into tight UAV bays where differential pressure sensors would not fit.
Recomendado
Automotive Auxiliary Pressure Sensing
While not AEC-Q100 qualified, the MPXV5050GP is used in non-safety automotive subsystems such as cabin HVAC, fuel-tank pressure, and accessory monitoring. Its -40C to +125C qualified range covers under-hood applications with external thermal isolation. The ratiometric output is compatible with most automotive 5 V analog sensor interfaces, and the SO-8 SMD footprint fits standard automotive PCB patterns.

Notas de projeto
Power the MPXV5050GP from a low-noise 5 V rail; the integrated bipolar op-amp has limited PSRR above a few kHz, so a noisy switcher will couple directly into the analog output. Add a 100 nF ceramic decoupling capacitor close to pins 1-2 (VCC) and a 1-10 uF bulk capacitor on the same rail. Avoid sharing the sensor ground with high-current return paths to prevent offset shifts.
Route the analog output (pin 7) as a short trace surrounded by ground on both sides of the PCB. If the trace must extend more than a few centimetres to the ADC, add a low-pass RC filter (1 kohm + 100 nF) to suppress coupled EMI. The output bandwidth of the on-chip op-amp is limited, so heavy capacitive loads greater than 1 nF should be buffered with a follower to prevent output distortion.
The MPXV5050GP is calibrated for dry air as the pressure medium. Contact with water, fuel, or aggressive chemicals can permanently damage the die. For non-air media, request NXP media compatibility guidance, or use the MPXV5050GP only on the air side of a sealed interface. Also note that the device is vented gauge (one port references ambient) - blocking the vent will cause drift and inaccurate readings.
