MPXV4006GP Übersicht
A pressure sensor converts an applied differential or absolute pressure into an electrical signal. Vented gauge types like the MPXV4006GP use a reference vent on the back side of the die, so the output reflects pressure relative to atmospheric pressure rather than a sealed vacuum. The MPXV4006G series targets medical, consumer, and industrial devices and falls within the broader sensor category of micro-electro-mechanical systems (MEMS), which combine mechanical diaphragms and silicon signal processing.
Key specifications include a typical full-scale span of 4.5 V (from 0.2 V at 0 kPa to 4.7 V at 6 kPa), an accuracy of ±5 percent, a temperature compensation range of 10°C to 60°C, and an operating temperature range of -10°C to 60°C. The internal ASIC amplifies and corrects the raw Wheatstone-bridge output, so no external calibration circuitry is required.
The sensor uses a piezoresistive bridge whose resistance changes when the diaphragm deflects under pressure; the die reference vent stabilizes the offset against changes in atmospheric pressure. The factory-trimmed output eliminates the need for customer gain or offset adjustment.
Typical applications include medical CPAP and ventilator airflow monitoring, HVAC air-flow measurement, air-handling equipment, weather-station barometers, and consumer spirometers. The ratiometric analog output is compatible with most microcontroller ADC inputs.
Design consideration: keep the side port free of debris, route the analog trace away from switching regulators, and add an RC low-pass filter at the MCU ADC input if the application contains switching noise. The trade-off compared to digital-output sensors is simpler MCU interface versus no built-in signal conversion.

Typische Anwendungen
MPXV4006GP ist geeignet für 6 Anwendungs: CPAP and Ventilator Airway Pressure Sensing, HVAC Air-Flow and Duct Pressure Measurement, Weather Station Barometer, Consumer Spirometer and Peak-Flow Meter, Industrial Handheld Air-Quality Tester, Coffee Machine and Beverage Pump Monitor.
CPAP and Ventilator Airway Pressure Sensing
The MPXV4006GP's 0-6 kPa vented gauge range matches typical CPAP airway pressures (4-20 cmH2O) and ventilator flow-restriction pressure drops. Its ±5 percent accuracy from 10°C to 60°C covers clinical environments, and the integrated signal conditioning removes the need for external op-amps in compact medical devices. Placed inline between the blower motor and patient circuit, it provides a ratiometric 0.2 V to 4.7 V signal compatible with most medical-grade MCUs, enabling real-time closed-loop pressure control. The side-port barbed fitting accepts standard 3.17 mm tubing used in respiratory equipment.

HVAC Air-Flow and Duct Pressure Measurement
Building automation systems use the MPXV4006GP to measure low-pressure differential airflow across fans, filters, and Variable Air Volume (VAV) boxes. The 0-6 kPa window covers the typical airflow-pressure range of residential and light commercial ducts without saturating. The vented gauge reference corrects for atmospheric drift, so the same sensor can be reused on different building elevations. The SOP-8 side-port package mounts flat on a PCB adjacent to a tube pickup, simplifying the pneumatic interface. Its 5 V analog output pairs naturally with the building controller's ADC input and avoids costly 4-20 mA interface electronics.
Empfohlen
Weather Station Barometer
For hobbyist and consumer weather stations, the MPXV4006GP serves as a low-cost atmospheric barometer when configured to read absolute pressure variations around 100 kPa. The vented gauge mode dynamically references atmospheric pressure, allowing relative humidity and altitude compensation in firmware. The 0.2 V to 4.7 V output, sampled by an MCU ADC, yields millibar-resolution barometric trend data. The 8-pin SOP-8 SMD package reflows onto standard weather-shield boards alongside an ESP-class wireless MCU. Its -10°C to +60°C operating window covers outdoor shaded enclosures in most climates.
Empfohlen
Consumer Spirometer and Peak-Flow Meter
Compact consumer pulmonary-care devices use the MPXV4006GP because its 0-6 kPa span captures the back-pressure generated by a flow-restriction element during forced exhalation. The on-chip calibration (±5 percent) eliminates the per-unit factory trim step, reducing cost for high-volume consumer spirometers. The 5 V ratiometric output keeps total BOM under $15 including the tube and transducer tube fittings. Battery-powered portable designs benefit from the sensor's low 5 mA typical current draw and instant-on response with no warm-up period.
Empfohlen
Industrial Handheld Air-Quality Tester
Environmental monitoring devices use the MPXV4006GP for particulate-filter back-pressure or draft-detector duties. Its SOP-8 package mounts on a probe-handle PCB near a small orifice, and the ratiometric analog output feeds a microcontroller ADC for instant pressure indication. The vented gauge reference makes the sensor immune to local barometric shifts during field use, which is critical for industrial hygiene surveys that span different elevations or weather systems. The 5 V supply is typically provided by a switching regulator with a low-noise filter to keep the analog trace clean.
Empfohlen
Coffee Machine and Beverage Pump Monitor
Espresso machines and soda dispensers use the MPXV4006GP to monitor pump line pressure in the 0-6 kPa range and verify flow-through or blockage events. The output voltage scales directly with back-pressure, so an MCU can detect a clogged filter or closed valve in firmware without analog comparator circuitry. The vented-gauge reference ensures consistent readings regardless of the machine's elevation, and the side-port barbed fitting accepts food-grade silicone tubing. The SOP-8 SMD package reflows onto an internal board with no mechanical mounting hardware beyond the PCB footprint.

Wichtigste Unterscheidungsmerkmale
- On-chip signal conditioning eliminates external amplifiers (vs. MPX5050GP)
- Lower pressure range optimised for airflow and medical applications (vs. MPXV7002DPT1)
- Side-port barbed mechanical interface (vs. MPXV7002DPT1)
Designhinweise
Estimated: Place a 0.1 µF ceramic bypass capacitor within 2 mm of pin 1 (VCC) and a 4.7 µF tantalum or ceramic bulk capacitor on the supply rail to suppress ripple. Route the analog OUT trace (pin 3) over a solid ground plane and keep it at least 5 mm away from any switching-regulator switching node to avoid coupled noise into the low-level output.
Do not apply pressure that exceeds the 6 kPa full-scale, even briefly, as it can damage the silicone diaphragm. Confirm that the ratiometric output is read by an ADC whose reference is tied to the same 5 V rail feeding the sensor; otherwise supply variations are not cancelled. For humid or condensing environments, choose the MPVZ4006GWT1 gel-isolated variant instead of the bare-die MPXV4006GP.
Estimated: With a 5 V supply and 4.5 V full-scale span, the output sensitivity is 4.5 V / 6 kPa = 0.75 V/kPa, or 750 µV per 1 Pa change. Add an external RC low-pass filter (for example 10 kΩ + 100 nF giving 160 Hz cutoff) at the ADC input to suppress higher-frequency noise without losing dynamic pressure events. The sensor's source impedance is approximately 1.5 kΩ so keep ADC input currents below 50 µA to avoid loading errors.
Estimated: At 25°C ambient with 5 mA operating current and a 5 V supply, the sensor dissipates approximately 25 mW; thermal rise is negligible (<1°C) and does not require explicit heatsinking. However, place the sensor away from heat sources such as motor drivers or power resistors, since temperature gradients across the SOP-8 package can introduce offset drift greater than the ±5 percent spec limit.
Compliance-Informationen
RoHS compliant per NXP product page. AEC-Q100 not applicable - this is a consumer/industrial MEMS sensor, not an automotive-qualified part. Confirm halogen-free status with NXP if required.
