MPXV10GC6U 概述
A piezoresistive pressure sensor is a MEMS device in which a silicon diaphragm with embedded strain-resistive elements deflects under pressure, producing a differential voltage output via a Wheatstone bridge. Within the sensor hierarchy, the MPXV10GC6U belongs to the family of uncompensated raw-bridge pressure sensors, which sit below calibrated/temperature-compensated sensors but above simple mechanical pressure switches. Engineers select uncompensated parts when they want to apply custom linearization, temperature compensation, and amplification networks in firmware or with external op-amps.
Key features include a 0 to 10 kPa operating range with vented gauge reference, 35 mV full-scale output at 3 V supply, low power consumption suitable for portable or battery-powered systems, and a top-side tube port (3.18 mm / 0.13") for hose-attach pneumatic interfacing. The uncompensated nature means the sensor ships without onboard calibration, giving designers full control over offset, span, and thermal compensation.
The MPXV10GC6U uses a single-element piezoresistive bridge fabricated on a silicon die. Output is ratiometric to supply voltage, which simplifies system-level calibration when the excitation is also used as the ADC reference. Designers must add a low-noise instrumentation front-end (typically an op-amp with adjustable gain) and an external temperature compensation network because raw bridge output drifts with temperature.
Typical applications include medical respiratory monitoring, HVAC airflow sensing, altimeters and barometric aids, industrial process control, and consumer health devices such as blood pressure monitors. The vented gauge reference simplifies absolute-pressure readouts when paired with a calibrated airflow inlet.
When designing with this sensor, place a low-offset, low-noise instrumentation amplifier directly adjacent to the output pins to avoid PCB-level noise pickup on the millivolt-scale signal. Use ratiometric ADC sampling tied to the same 3 V excitation as the bridge to cancel supply-noise error.
This page synthesizes distributor pricing, drop-in alternatives, application circuits, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single, decision-ready reference for the MPXV10GC6U.

典型应用
MPXV10GC6U 适用于 7 应用s: Medical Respiratory Monitoring, HVAC Airflow and Duct Pressure Sensing, Barometric Altimeter and Weather Station, Industrial Process Control and Pneumatic Gauges, Consumer Blood Pressure Monitors, Drone Altitude Hold and Variometer, Aquarium and Hydroponic Water Level Sensing.
Medical Respiratory Monitoring
The MPXV10GC6U's 0-10 kPa range matches the pressure differential of human airflow during spirometry and CPAP/BiPAP machines, where peak inspiratory pressures rarely exceed 5-8 kPa. The vented-gauge reference cancels ambient atmospheric drift, critical for accurate breath-flow measurements. Output of 35 mV at 3 V gives ~3.5 mV/kPa sensitivity which, after an INA333 instrumentation amp, drives a 24-bit ADC at sub-Pa resolution.
推荐
HVAC Airflow and Duct Pressure Sensing
Building automation systems monitor duct static pressure in the 0-1.5 kPa range to detect filter clogging, fan performance, and VAV damper position - well within the MPXV10GC6U's 10 kPa full-scale with comfortable headroom. The 8-pin SO package with top-side tube port simplifies hose attachment to standard 1/4" pneumatic fittings via barbed adapters. Vented-gauge mode compensates for altitude and weather barometric swings automatically.
推荐
Barometric Altimeter and Weather Station
Atmospheric pressure variations of ~10 kPa between sea level and 3000 m altitude make the MPXV10GC6U ideal for handheld altimeters and DIY weather stations. The vented-gauge reference through the top tube port provides direct access to ambient air, giving real-time barometric data when paired with a logarithmic altitude conversion. Output ratiometricity at 3 V simplifies single-rail battery-powered designs.
推荐
Industrial Process Control and Pneumatic Gauges
Factory pneumatic systems monitoring low-pressure gas lines (air, nitrogen, CO2) typically operate below 10 kPa, perfectly matching the MPXV10GC6U's full-scale. The SO-8 surface-mount package allows compact PCB integration inside gauge enclosures, while the 3.18 mm tube port accepts standard pneumatic push-to-connect fittings. Industrial -40 C to +125 C rating covers most plant environments.
推荐
Consumer Blood Pressure Monitors
Wrist and finger cuff-style blood pressure monitors inflate cuffs to 30 kPa and measure oscillometric pulsations in the 0-10 kPa range - exactly where the MPXV10GC6U operates. The uncompensated raw bridge allows the designer to apply proprietary cuff-inflation algorithms and oscillometric peak detection in firmware. The compact 8-pin SO package fits inside the small enclosures required by wearable BPM form factors.
推荐
Drone Altitude Hold and Variometer
Lightweight drones need barometric altitude feedback for altitude-hold stabilization, and the MPXV10GC6U's 3.18 mm top port plus 10 kPa range gives a 10 m to 10,000 m altitude coverage. The uncompensated raw mV output allows the flight controller to apply custom temperature compensation using onboard thermistors. At 3 V excitation the sensor consumes <1 mA, suitable for battery-powered flight systems.
推荐
Aquarium and Hydroponic Water Level Sensing
Bubbler-type aquarium monitors bubble air through a tube to the bottom of a tank; the resulting back-pressure at 0-10 kPa maps to water column height - a perfect use of the MPXV10GC6U's range and vented-gauge reference. The vent port automatically compensates for ambient barometric changes that would otherwise corrupt the depth reading. Top-side tube port accepts standard aquarium airline tubing directly.

设计说明
The MPXV10GC6U outputs a raw Wheatstone bridge signal in the 0-35 mV range at 3 V excitation, which is highly susceptible to PCB-level noise pickup. Place a low-offset, low-noise instrumentation amplifier (e.g., INA333, AD8420, or AD620) directly adjacent to the sensor output pins to minimize trace-length noise pickup. Use a guard ring or ground plane around the bridge traces to reject EMI. Estimated: with 35 mV full-scale and a 24-bit ADC reference of 3 V, the LSB size is ~178 nV, so even microvolt-level noise translates to meaningful ADC error.
Do not route the bridge output traces over switching power supply or digital clock traces - the 35 mV full-scale signal can be corrupted by tens of millivolts of switching noise. Use a separate analog ground (star-grounded at the ADC reference) and decouple the 3 V excitation with 10 uF + 0.1 uF ceramics right at the sensor VS pin. Ratiometric sampling (using the same 3 V supply as the ADC reference) cancels supply-noise error; if a separate regulator is used for the bridge and ADC, expect loss of ratiometric accuracy.
Uncompensated pressure sensors drift with temperature due to bridge resistance change. Apply a thermistor-driven offset correction in firmware, or use an analog temperature-compensation network with a matched NTC thermistor bonded to the sensor package. The MPXV10GC6U operating range is -40 C to +125 C, but precision applications should limit self-heating by keeping excitation voltage low (3 V typical) and avoiding enclosed thermal environments. Estimated: typical uncompensated bridge drift is on the order of 1-2% FS per 10 C without correction.
The 8-pin SO package uses 2.54 mm pin pitch on a standard SO-8 land pattern, simplifying PCB layout. Leave clearance around the top-side tube port to allow hose attachment without mechanical stress on the package. Add a strain-relief loop in the pneumatic tubing within 50 mm of the port to prevent axial loads from damaging the sensor. Sealed enclosures around the port side may need vent holes to avoid pressurizing the package cavity.
