MPXV4006DP Overview
A piezoresistive pressure sensor is a MEMS device in which diffused silicon strain gauges form a Wheatstone bridge on a micromachined diaphragm; when differential pressure is applied across the diaphragm, the bridge outputs a voltage proportional to the applied pressure. Piezoresistive sensors sit within the broader category of silicon pressure transducers, which in turn belong to the MEMS (micro-electromechanical systems) sensor family used in industrial, consumer, healthcare, and appliance applications. The MPXV4006DP combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing to deliver a calibrated analog signal.
Key specifications include a 5 V typical supply voltage (4.75 V to 5.25 V range), 0.2 V to 4.7 V output span, sensitivity of approximately 766 mV/kPa, and an operating temperature range of -10 °C to +60 °C. The differential configuration measures the pressure difference between two ports on the same side of the package, making it suitable for flow-based measurements where one port references ambient pressure. The 8-BSOP surface-mount package simplifies PCB assembly while preserving the dual-port pneumatic connection.
Typical applications include HVAC variable-air-volume (VAV) controllers, respiratory monitoring equipment, weather station barometric pressure measurement, and industrial process monitoring. The wide 4.7 V full-scale output swing maximizes ADC resolution when sampled by 5 V-tolerant microcontroller ADCs. The integrated temperature compensation maintains accuracy across the operating range without external calibration.
When designing with this part, route the analog output trace away from switching noise sources and add a small RC filter near the ADC input to suppress high-frequency noise. The dual-port package requires a pneumatic manifold or flexible tubing for the pressure source, and the gel-filled port design protects the die from humid and mildly contaminated media.

Typical Applications
MPXV4006DP is suitable for 7 applications: HVAC Variable Air Volume (VAV) Control, Medical Respiratory Monitoring, Industrial Process Pressure Monitoring, Appliance Water-Level / Flow Sensing, Weather Station Barometric Pressure Trend, Consumer Health Wearable Equipment, Air-Flow Rectification and Duct Monitoring.
HVAC Variable Air Volume (VAV) Control
The MPXV12014DP is a 6 kPa differential pressure sensor well-suited to HVAC VAV box control because the differential measurement captures the pressure drop across a flow-restricting element, and the ratiometric 0.2 V to 4.7 V output interfaces cleanly with 5 V HVAC controller boards. Its 6 kPa full-scale covers standard duct static-pressure spans of 0 to 1 inch water column, and the on-chip temperature compensation maintains calibration across building environmental conditions. Compared with discrete bridge sensors, the integrated signal conditioning eliminates drift-prone external op-amp circuitry in long-lifecycle building equipment.
Recommended
Medical Respiratory Monitoring
The MPXV4006DP's 0 to 6 kPa differential range matches the pressure changes generated by human respiration across an airflow restrictor, making it useful for spirometry and CPAP/BiPAP flow-monitoring subsystems. On-chip temperature compensation and gel-isolated die tolerate humid exhaled air without condensation damage, and the ratiometric 0.2 V to 4.7 V analog signal feeds directly into medical MCU ADCs. For FDA-regulated products, validate full system accuracy, biocompatibility, and drift performance against applicable medical standards.
Recommended
Industrial Process Pressure Monitoring
The MPXV4006DP serves industrial low-pressure process monitoring applications such as filter-staleness detection, cleanroom pressure differential verification, and vacuum-line status indication. The differential configuration measures the pressure difference between upstream and downstream points, and the 8-BSOP surface-mount package withstands standard reflow profiles. The 5 V supply and on-chip calibration eliminate the need for periodic field recalibration, which reduces total cost of ownership in remote or hard-to-access installations.
Recommended
Appliance Water-Level / Flow Sensing
Consumer appliances such as washing machines and dishwashers use low differential pressures to infer water level or flow rate; the MPXV4006DP captures these pressures across an orifice with its 0 to 6 kPa range and 0.2 V to 4.7 V analog output. The 8-BSOP surface-mount package is compatible with high-volume automated assembly, and the calibrated output eliminates per-unit factory trim steps. Compared with discrete strain-gauge bridges, the integrated signal path reduces BOM cost and improves long-term reliability in damp appliance environments.
Recommended
Weather Station Barometric Pressure Trend
Although a true barometric measurement uses gauge reference, the MPXV4006DP supports weather-station differential trend detection when one port is exposed to ambient and the other is sealed against a reference chamber. The 6 kPa range covers typical barometric fluctuation in absolute terms, and the on-chip temperature compensation maintains reading accuracy across outdoor temperature swings. The 8-BSOP package fits compact weather-station PCB designs alongside the MCU and RF transceiver.
Recommended
Consumer Health Wearable Equipment
The MPXV4006DP supports consumer health wearables that need compact low-pressure differential sensing for airflow, body-cavity pressure, or vacuum-pump feedback. The 8-BSOP package occupies less than 12 mm of board width, fitting inside wristbands, sleep monitors, or wearable respiratory trackers. The 5 V supply and 6 mA-class current draw suit battery-powered devices when paired with a boost converter, and the gel-protected die tolerates the humidity generated by skin contact during prolonged wear.
Recommended
Air-Flow Rectification and Duct Monitoring
The MPXV4006DP serves duct air-flow monitoring applications in buildings, server rooms, and fume hoods by measuring differential pressure across flow-restricting elements such as orifice plates or Pitot tubes. The 6 kPa full-scale covers duct static pressures up to 24 inches water column when measured across a calibrated flow restriction. The 0.2 V to 4.7 V analog output connects directly to building-automation controller ADC inputs, and the integrated calibration removes the per-channel compensation resistor networks required by barebridge alternatives.

Key Differentiators
- Differential dual-port-same-side configuration (vs MPXV4006GC6U)
- On-chip signal conditioning and temperature compensation (vs XGZP6899A)
- Wide 4.5 V output swing maximizes ADC resolution (vs MPVZ4006GW7U)
Design Notes
Power the MPXV4006DP from a low-noise 5 LDO regulator (such as an LM7805 or low-dropout equivalent) with at least 10 uF of bulk decoupling near the Vs pin. The output is ratiometric, so any supply ripple couples proportionally into the analog output and degrades measurement accuracy. A 100 nF ceramic decoupling capacitor placed within 5 mm of the Vs pin suppresses high-frequency switching noise from adjacent digital circuitry.
Route the Vout trace away from switching nodes, clock lines, and high-current traces to minimize capacitive coupling. Add a first-order RC low-pass filter (10 kohm and 100 nF typical) at the ADC input to suppress out-of-band noise; the filter corner of approximately 160 Hz is well below typical ADC sample frequencies. For long cable runs between the sensor and the MCU, use a differential amplifier or shielded cable to preserve signal integrity.
Do not apply pressure exceeding the maximum overload rating; refer to the MPXV4006 datasheet for the absolute maximum. Confirm pneumatic-port orientation against the PCB footprint before soldering, since the dual-port-same-side DP variant is physically distinguishable from the single-port GC variants only by port arrangement. Avoid contaminating the gel-isolated port with solvents, adhesives, or conformal coatings that contact the gel column directly.
Compliance Information
RoHS compliance per the STMicroelectronics product page. AEC-Q100 is not applicable because this is a pressure sensor IC rather than an automotive-qualified semiconductor. REACH compliance status inferred from STMicroelectronics product family documentation; consult manufacturer declaration for confirmation.
