MPVZ7025G6U Overview
A pressure sensor is a transducer that converts an applied gas or fluid pressure into a proportional electrical signal. Compound pressure sensors specifically measure both positive (above atmospheric) and negative (vacuum, below atmospheric) pressure relative to a sealed reference, making them ideal for applications where the pressure can swing across atmospheric in either direction. In the broader sensor hierarchy, pressure sensors fall under MEMS (micro-electromechanical systems) -> physical sensors -> sensors. The MPVZ7025G6U's monolithic silicon diaphragm with integrated piezoresistive bridge is the defining technology of this category.
Key features include ±25 kPa (±3.63 PSI) compound measurement range, 0.2 V to 4.7 V analog output swing at 5 V VDD, ±5% accuracy across the compensated temperature range, and supply voltage operation from 4.75 V to 5.25 V. Operating temperature range is -40 °C to +125 °C with integrated temperature compensation over 0 °C to 85 °C. The SMD-8 module integrates the sensor die, signal conditioner, and compensation network in a single surface-mount package, eliminating the need for external analog conditioning circuitry.
Technically, the device uses a monolithic piezoresistive bridge whose resistance changes with diaphragm deflection. The integrated ASIC amplifies the differential bridge signal, normalizes it across temperature, and scales it to the standardized 0.2 V-4.7 V output. Ratiometric output means the output voltage scales linearly with supply voltage, allowing ADC reference tied to VDD to cancel supply noise automatically.
Typical applications include HVAC differential pressure sensing, medical respiratory equipment, industrial process control, altimeters and weather stations, and vacuum monitoring systems. The compound range (-25 kPa to +25 kPa) makes it especially suited to applications where pressure can be above or below ambient. The 8-SMD no-port form factor uses a gel-filled top entry for harsh media compatibility.
When designing with this device, follow manufacturer reference designs for input filtering and PCB land pattern geometry. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the supply pin. The output is ratiometric - tie the ADC reference to VDD for automatic noise cancellation. Avoid mechanical stress on the package during board assembly.

Typical Applications
MPVZ7025G6U is suitable for 7 applications: HVAC Differential Pressure Monitoring, Medical Respiratory Equipment, Industrial Vacuum and Process Control, Altimeter and Weather Station Sensing, Fuel Cell and Battery Pressure Monitoring, Pneumatic System Monitoring, White Goods and Appliance Pressure Sensing.
HVAC Differential Pressure Monitoring
The MPVZ7025G6U's ±25 kPa compound range and ratiometric 0.2 V to 4.7 V output make it a strong match for differential pressure monitoring across air filters, duct sections, and blower assemblies in HVAC systems. With ±5% accuracy over the 0-85 °C compensated range and on-chip signal conditioning, no external op-amp or trim network is required - the sensor output feeds an ADC channel directly. The no-port gel-filled housing accepts airflow without exposing the silicon die to contaminants, dust, or moisture typical of return-air plenums. Tying the ADC reference to the same 5 V rail cancels supply noise. Companion components: NXP MPC5604P MCU for system control and NXP MC33664 isolated communication.
Recommended
Medical Respiratory Equipment
The MPVZ7025G6U is widely used in CPAP machines, respirators, and spirometers where measuring both positive (exhalation) and negative (inhalation) airway pressure is required. The compound -25 kPa to +25 kPa range captures the full respiratory cycle, and the 0.2 V-4.7 V output is easily digitized by medical-grade ADCs. The gel-filled cavity accepts humidified breathing air, and the ±5% accuracy over the 0-85 °C compensated range meets clinical instrumentation tolerances. AEC-Q100 is not required for medical, so the standard MPVZ7025G6U is preferred. Companion components: NXP Kinetis K64 MCU for safety-critical control and TI ADS1292 analog front-end.
Recommended
Industrial Vacuum and Process Control
Industrial vacuum systems, pick-and-place vacuum generators, and process control loops all benefit from the MPVZ7025G6U's compound pressure range, which captures both vacuum (below atmospheric) and slight overpressure conditions. The 8-SMD surface-mount form factor enables automated PCB assembly in high-volume industrial sensor modules, and the -40 °C to +125 °C operating range covers outdoor and unheated enclosure installations. The ±5% accuracy and integrated temperature compensation eliminate per-board calibration in volume production. Companion components: NXP LPC54608 MCU for industrial Ethernet connectivity and TI ISO1541 I2C isolator.
Recommended
Altimeter and Weather Station Sensing
The MPVZ7025G6U's ±25 kPa range covers barometric pressure variations (typically ±5 kPa around 101 kPa atmospheric baseline) and can be calibrated for altitude measurement up to approximately 2,000 m. Weather stations use it for barometric trend monitoring, and the gel-filled housing protects against humidity, condensation, and dust in outdoor deployments. The on-chip temperature compensation over 0-85 °C is sufficient for most outdoor enclosure designs with internal heating. Companion components: NXP FXOS8700 accelerometer for combined altitude/inclination and TI CC1310 LED bar for wireless data.
Recommended
Fuel Cell and Battery Pressure Monitoring
In fuel cell systems and sealed battery packs, the MPVZ7025G6U monitors internal pressure buildup, vacuum during cooling cycles, and gas leakage. The compound range supports bidirectional pressure swing typical of PEM fuel cell anode/cathode loops, and the gel-filled housing tolerates humid hydrogen and oxygen environments. The 5 V supply aligns with typical fuel cell controller rails. The ±5% accuracy is sufficient for trend monitoring and safety threshold detection. Companion components: NXP MPC5644A MCU for fuel cell management and TI INA240 current sense.
Recommended
Pneumatic System Monitoring
Compressed air systems, pneumatic actuators, and vacuum grippers in factory automation benefit from the MPVZ7025G6U's compound -25 kPa to +25 kPa range, which captures both vacuum (suction) and positive (pressure) states of pneumatic tools. The 8-SMD no-port housing accepts tubing via manifold adapters and resists oil/contaminant exposure in industrial pneumatics. The on-chip signal conditioning eliminates the analog front-end that would otherwise be required for raw bridge sensors. Companion components: NXP KV46 MCU for motor/valve control and TI DRV8871 motor driver.
Recommended
White Goods and Appliance Pressure Sensing
Washing machines, dishwashers, and water-level sensors use the MPVZ7025G6U to monitor pump pressure, inlet/outlet flow, and sealed-chamber pressure. The compound range accommodates both pump discharge (positive) and drain siphon (vacuum) cycles. The gel-filled housing tolerates detergent residue and humid air, and the surface-mount package supports automated assembly in high-volume appliance production. The ±5% accuracy is adequate for water-level and pump-fault detection rather than precision metering. Companion components: NXP KEAZ128 MCU for appliance control and TI ULN2003 relay driver.

Design Notes
Decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin. Use a 10 µF bulk capacitor if the 5 V rail is shared with high-current switching loads. The MPVZ7025G6U is ratiometric - tie the ADC reference voltage to the same 5 V rail to automatically cancel supply noise. For best noise performance, use a low-noise LDO (such as NXP's TLV1117LV or TI's TPS7A47) rather than a switching regulator near the sensor.
Follow the land pattern geometry in the NXP MPXV7025 series datasheet exactly. The gel-filled cavity has a specific orientation - the dot or chamfer marks pin 1. Do not route high-speed digital signals or switching power traces under the sensor package; mechanical stress from PCB flex can shift the calibrated zero point. Maintain at least 3 mm clearance around the package to avoid mechanical stress coupling during board depanelization.
Route the analog output (pin 1) as a short, guarded trace with ground plane underneath. Place a 1 nF to 10 nF ceramic capacitor at the ADC input if the trace length exceeds 25 mm to filter coupled noise. The output is high-impedance during power-up ramp - allow at least 5 ms after VCC settles before sampling the output to avoid transient readings. For multi-sensor arrays, use separate ADC channels with individual RC filters rather than a multiplexer (which adds charge-injection transients).
Do not expose the gel-filled cavity to direct jet impingement or sharp objects - the silicone gel can be displaced or punctured, permanently damaging the sensor. Do not solder the package with a profile hotter than the JEDEC J-STD-020 MSL3 reflow maximum (260 °C peak, 60 s above 217 °C). Do not use the sensor in vacuum environments below -25 kPa absolute or above +25 kPa gauge, as the calibrated range is exceeded. Do not apply pressure transients faster than 1 ms - the silicon diaphragm is tuned for slow-changing pressures and may be damaged by shock waves.
Compliance Information
