MPXV7025GC6T1 Overview
A board-mount pressure sensor, also called a piezoresistive transducer or pressure sensor IC, is a semiconductor device that converts applied pressure into a proportional electrical signal. Within the broader hierarchy, this places it as a pressure sensor -> sensor -> transducer -> signal conditioning device. Piezoresistive sensors use a Wheatstone bridge of strain-sensitive silicon resistors etched into a diaphragm; when pressure deflects the diaphragm the bridge produces a differential voltage that is then amplified and offset on-chip. The integrated signal path of the MPXV7025GC6T1 eliminates external compensation circuitry, simplifying design-in.
Key features include factory calibration across 0 to 85 °C, a low supply current of approximately 7 mA typical, an operating temperature range of -40 °C to +125 °C, and a top-side axial port that accepts 3.18 mm tubing for direct connection to the measured gas. The output is ratiometric with VDD, which means the full-scale span scales with supply voltage and allows simple ADC interfacing using the supply as the reference. The 8-SMD, gull-wing package simplifies SMT assembly and provides mechanical robustness for industrial environments.
The MPXV7025 series piezoresistive transducer is built on a monolithic silicon process that integrates the sensing diaphragm, the Wheatstone bridge, and the signal-conditioning ASIC on a single die. The on-chip ASIC provides offset trimming, span calibration, and temperature compensation, so designers do not need to perform multi-point calibration in firmware. This architecture yields a typical accuracy within a few percent of full-scale span across the calibrated temperature range, which is sufficient for HVAC, medical respiratory, and appliance applications.
Typical applications are HVAC damper control and airflow monitoring, medical respiratory equipment such as ventilators and CPAP machines, appliance pressure sensing including washing-machine water level and dishwasher flow, altimeters and barometric aids, and industrial pneumatic control. The 0.2 V to 4.7 V output swings nearly full-scale between the rails and is well matched to 5 V ADCs and microcontrollers.
When designing with this device, ensure the supply is well regulated because the output is ratiometric: noise or drift on VDD appears directly on VOUT. Place a 100 nF decoupling capacitor close to the VDD pin and a small capacitor on the output if the load is highly capacitive. The axial port accepts 3.18 mm tubing; use flexible silicone or polyurethane tubing with a press fit, and avoid kinking the line near the port.

Typical Applications
MPXV7025GC6T1 is suitable for 7 applications: HVAC Damper Control and Airflow Monitoring, Medical Respiratory Equipment (CPAP / Ventilator), Appliance Water-Level and Flow Sensing, Industrial Pneumatic Pressure Monitoring, Altimeter and Barometric Aid, Variable-Speed Compressor and Vacuum Cleaner Load Sensing, Process Control and Instrumentation.
HVAC Damper Control and Airflow Monitoring
The MPXV7025GC6T1's ±25 kPa gauge range and 0.2-4.7 V ratiometric output are well matched to HVAC duct pressure sensing, where 0-500 Pa to 0-25 kPa spans are common. The 8-SMD top-port package accepts 3.18 mm tubing for direct plenum tap installation, while the 5 V supply interfaces cleanly with HVAC controller MCUs without extra level translation. The on-chip temperature compensation from 0-85 °C removes the need for software lookup tables in environmental controllers, and the -40 to +125 °C operating range covers rooftop and basement equipment.
Recommended
Medical Respiratory Equipment (CPAP / Ventilator)
The MPXV7025GC6T1 is widely designed into CPAP machines and ventilators because its ±25 kPa range covers typical airway pressures (4-25 cm H2O peak inspiratory) with margin, and the 0.2-4.7 V analog output maps cleanly onto a 5 V ADC channel. Factory calibration and on-chip temperature compensation reduce firmware burden in IEC 62304 risk-managed medical software, while the small 8-SMD package fits inside compact handheld device enclosures. Pair with a low-noise 5 V LDO such as an NXP MC33PF8100 for stable ADC reference.
Recommended
Appliance Water-Level and Flow Sensing
Washing machines and dishwashers use the MPXV7025GC6T1 to sense hydrostatic pressure in a vertical standpipe, where 0-25 kPa corresponds roughly to 0-2.5 m of water column. The top axial port accepts 3.18 mm tubing for direct connection to the sump or standpipe, and the ratiometric output compensates for any 5 V rail sag from a shared DC bus. The 7 mA typical supply current is acceptable for ENERGY STAR-rated appliances, and the factory calibration avoids expensive per-unit trim during production.
Recommended
Industrial Pneumatic Pressure Monitoring
In factory pneumatic systems running at 0-100 kPa, the MPXV7025GC6T1 provides direct monitoring of regulated supply and actuator lines up to its ±25 kPa range. The 8-SMD gull-wing package is suitable for conformal-coated industrial controller boards, and the -40 to +125 °C operating range survives unheated cabinet installations. The 5 V supply and ratiometric output pair with NXP Kinetis or i.MX RT MCUs already used on the same board.
Recommended
Altimeter and Barometric Aid
Although 25 kPa absolute pressure spans 75-100 kPa at sea level (only partial atmospheric range), the MPXV7025GC6T1 can serve as a relative pressure reference in differential barometric designs when paired with a sealed reference cavity. For handheld altimeters a gauge-mode reading against a sealed port produces changes in elevation directly. The 0.2-4.7 V output feeds a 12-bit ADC for sub-meter altitude resolution with averaging.
Recommended
Variable-Speed Compressor and Vacuum Cleaner Load Sensing
Vacuum cleaners and small compressors use the MPXV7025GC6T1 to monitor inlet or outlet pressure and modulate motor speed via an MCU-driven inverter. The MPXV7025GC6T1's fast response and 5 V supply are well matched to inverter control boards already using 5 V MCUs. Factory calibration eliminates manual offset trim during mass production, while the small 8-SMD top-port package allows flexible placement on crowded power boards.
Recommended
Process Control and Instrumentation
Industrial process controllers monitor tank headspace or line pressure with the MPXV7025GC6T1 when pressures are within ±25 kPa, particularly in pharmaceutical or food-grade skids where sealed sensor modules are preferred. The on-chip calibration supports traceable measurement without per-board trim, and the small 8-SMD package fits into DIN-rail-mounted transmitter heads. Pair with 4-20 mA loop drivers and HART modems for plant-wide SCADA integration.

Key Differentiators
- Same top-port footprint with broader pressure range than MPXV7002GC6T1 (vs MPXV7002GC6T1)
- Single-port axial gauge topology simplifies plumbing vs differential MPXV7007DPT1 (vs MPXV7007DPT1)
- Tube-packaging variant MPXV7025GC6U shares full spec with no design change (vs MPXV7025GC6U)
- Top axial port orientation vs side port on MPXV7025GP (vs MPXV7025GP)
Design Notes
The MPXV7025GC6T1 output is ratiometric with VDD, so any noise or drift on the 5 V rail appears directly on VOUT. Place a 100 nF X7R decoupling capacitor within 5 mm of the VDD pin and a bulk 1-10 uF capacitor on the regulator output. Sharing the ADC reference with the same regulated 5 V rail eliminates reference errors in 5 V MCU systems.
Keep the analog VOUT trace short and away from switching nodes such as MCU PWM outputs or DC-DC converters to avoid coupled noise. Use a ground plane under the device to shield against radiated EMI, and reserve a quiet analog ground island if mixed-signal components are nearby. The top axial port should connect to flexible tubing free of mechanical stress; constrain tubing so that pulling does not torque the package.
Do not block the top axial port during PCB assembly - many stencil/cleaning processes can leave residue in the port that shifts readings. Apply Kapton tape over the port during reflow and wash cycles, then remove before final test. Also avoid mounting the device with the port facing down, as condensate can collect and bias the reading. The supply must remain in the 4.75-5.25 V window; dropping below 4.75 V reduces the full-scale output proportionally.
Estimated: with a 12-bit ADC and 5 V reference (1 LSB = 1.22 mV), the 4.5 V span of the MPXV7025GC6T1 yields ~3685 codes across the pressure range, or roughly 13.6 codes per kPa. Averaging 16 samples reduces noise to ~3.4 codes per kPa, sufficient for sub-100 Pa resolution after calibration. Add a 100 nF cap on VOUT at the ADC input if the source impedance causes ADC sample-cap charge-sharing errors.
