MPXV5050DP 概要
A pressure sensor is a transducer that converts an applied pneumatic or hydraulic pressure into a proportional electrical signal; differential variants like the MPXV5050DP measure the difference between two applied pressures through two ports, while gauge variants measure against atmosphere. Piezoresistive silicon sensors dominate low-pressure applications because the Wheatstone bridge of strain-sensitive diffused resistors changes resistance proportionally to membrane deflection, and on-chip CMOS/bipolar signal conditioning converts that small bridge delta into a high-level, ground-referenced voltage that downstream microcontrollers can sample. Within the broader sensor taxonomy, the MPXV5050DP belongs to MEMS pressure sensors, a sub-class of motion/force sensors used wherever clean, conditioned pressure data is needed.
Key features include: 0 to 50 kPa operating range, 5 V typical supply (max 6.0 V), ratiometric analog output nominally Vout = 5 V x (0.009 x P(kPa) - 0.045) over the 0 to 50 kPa span, on-chip temperature compensation over 0 C to +85 C, differential dual-port configuration on the same side, low standby current, and AEC-Q100 qualification for automotive use. The integrated bipolar op-amp front end and thin-film trim network provide a factory-trimmed offset and span, eliminating the manual calibration that discrete bridge sensors require.
Technically, the part uses a single-element monolithic diaphragm with a diffused piezoresistive bridge, advanced micromachining, thin-film metallization, and bipolar signal processing. Because the output is ratiometric with Vdd, ADC readings stay accurate even if the 5 V rail drifts, provided the MCU's ADC reference is also tied to the same 5 V supply. The dual-port differential topology allows measurement across an orifice, filter, or HVAC duct without exposing the sensor to ambient humidity contamination.
Typical applications include medical respiration/airflow monitoring, HVAC variable-air-volume (VAV) controllers, industrial process control, appliance pressure feedback (e.g., washing-machine water level), and automotive manifold absolute/differential sensing. The differential configuration makes it ideal for flow-via-orifice measurement, where a known restriction generates a measurable pressure drop.
When designing with this part, place 100 nF decoupling close to Vdd, keep port tubing short and rigid to dampen vibration, and use the same 5 V rail as the ADC reference for best accuracy. Avoid exposing the ports to condensing moisture or corrosive media; the device is specified for clean, dry, non-corrosive gases only.

主な用途
MPXV5050DP の用途: 6 件s: Medical Respiration and Airflow Monitoring, HVAC Variable Air Volume (VAV) Box Control, Industrial Process Control and Filter Monitoring, Automotive Manifold and Cabin Pressure Sensing, Appliance Water Level and Pressure Feedback, Portable Gas Flow and Air Quality Instruments.
Medical Respiration and Airflow Monitoring
Why the MPXV5050DP fits: the device's 0 to 50 kPa differential pressure range covers the typical 1 to 4 kPa pressure drop across a flow element used in respiration circuits and CPAP/BiPAP patient monitoring, while the 0.2 V to 4.7 V ratiometric output feeds directly into a low-cost MCU ADC without external instrumentation amplifiers. How it is used: the two same-side ports connect via short, rigid tubing across a flow-restrictive element (orifice, mesh, or Pitot tube); the MCU samples the differential voltage using the same 5 V rail as the ADC reference to keep ratiometric error below 1 percent. Performance consideration: the on-chip temperature compensation over 0 C to +85 C simplifies patient-side calibration, but designers must still implement IEC 60601-1 isolation, biocompatible tubing interfaces, and moisture barriers between the patient and the dual ports of this NXP sensor.

HVAC Variable Air Volume (VAV) Box Control
Why the MPXV5050DP fits: HVAC VAV boxes typically develop 0 to 250 Pa (0 to 1 kPa) differential across the damper/flow sensor, well within the lower portion of the MPXV5050DP's 0 to 50 kPa span, giving the controller headroom and good resolution near the operating point. How it is used: the differential ports sense across a multi-port airflow pick-up ring or Pitot-static tube, the 5 V ratiometric output is digitized by a 10 or 12-bit MCU ADC, and the controller modulates the damper actuator to maintain CFM setpoint. Performance consideration: the 200 kPa overload rating protects against duct transients during filter clogging, and the on-chip conditioning eliminates manual trim pots that drift over years of service in commercial ceilings.
おすすめ
Industrial Process Control and Filter Monitoring
Why the MPXV5050DP fits: filter differential pressure monitoring is a standard industrial use case where a clean element shows near-zero pressure drop and a clogged element rises into the kPa range; the MPXV5050DP's 50 kPa full scale and dual same-side ports simplify plumbing into pressurized air or liquid lines. How it is used: ports are teed into upstream and downstream manifolds of a filter housing, the analog output drives both an MCU ADC for trending and a comparator circuit for high-delta alarm. Performance consideration: the on-chip signal conditioning gives a calibrated 0.2 V to 4.7 V span without user trim, while the AEC-Q100 qualification supports process plants that also serve automotive customers with shared hardware.
おすすめ
Automotive Manifold and Cabin Pressure Sensing
Why the MPXV5050DP fits: AEC-Q100 qualification plus 50 kPa differential range suits automotive applications including fuel-pressure differential monitoring, cabin HVAC plenum sensing, and emissions back-pressure measurement, where pressures span single-digit kPa and the 5 V analog output connects directly to ECU ADCs. How it is used: the dual ports plumb across a flow restriction or vacuum line, the ratiometric output is sampled by the ECU ADC sharing the same 5 V sensor rail, and diagnostics flag out-of-range conditions. Performance consideration: although rated for clean dry gases only, the device handles under-hood temperatures when thermally sunked properly, and the integrated temperature compensation minimizes ECU calibration table size.
おすすめ
Appliance Water Level and Pressure Feedback
Why the MPXV5050DP fits: washing machines, dishwashers, and coffee equipment commonly sense water column pressure in the single-digit kPa range, mapping cleanly onto the MPXV5050DP's lower operating band; the surface-mount package enables compact appliance control boards. How it is used: the differential ports measure across a pressure chamber or air trap, the analog voltage is read by a low-cost 8-bit MCU, and the appliance controller actuates valves accordingly. Performance consideration: the differential topology rejects ambient atmospheric drift, and the on-chip factory trim eliminates per-unit calibration that would otherwise inflate manufacturing cost on high-volume appliance lines.
おすすめ
Portable Gas Flow and Air Quality Instruments
Why the MPXV5050DP fits: portable flow meters, breath analyzers, and indoor air quality instruments benefit from a low-power, conditioned, factory-calibrated differential pressure sensor that integrates into battery-powered enclosures; the MPXV5050DP's standby current and 5 V analog output suit 4-cell AA or Li-ion designs. How it is used: the dual ports sit across a laminar flow element or mesh screen, the ratiometric output is digitized by a low-power MCU ADC, and the result is displayed or transmitted via BLE. Performance consideration: the differential design rejects altitude and ambient barometric pressure changes, while the integrated temperature compensation keeps accuracy stable across indoor and field-use temperature swings.

設計ノート
Power the MPXV5050DP from a clean 5 V rail that is also used as the MCU ADC reference so the ratiometric output cancels Vdd drift. Place a 100 nF X7R ceramic bypass capacitor as close as possible to the Vdd pin, plus a 10 uF tantalum or ceramic bulk capacitor if the 5 V rail is shared with switching regulators. Do not exceed the 6.0 V absolute maximum supply rating even briefly during hot-plug events; add a TVS diode on Vdd if the supply is exposed.
Estimated: air at 25 C entering a 3.3 mm ID tube can cause lightly-damped resonance near 200 Hz, which the sensor reads as pressure ripple. Keep tubing short (<300 mm), use rigid tubing, and add a small acoustic damper (sintered plug) if the source includes a fan or compressor. The MPXV5050DP is rated for clean, dry, non-corrosive gases only; moisture, oil, or corrosive media will damage the silicon diaphragm - install a 5 micron inline filter if process air is not clean.
Solder the MPXV5050DP's SOT1693-1 footprint with no-clean flux and a standard reflow profile (peak 250 C, 60 s above 220 C). Avoid placing the ports directly over copper ground pours that could wick heat away from the package during reflow and crack the gel-filled cavity. Keep the analog output trace short and shielded from switching traces or PWM lines to avoid coupling noise into the MCU ADC sample window.
