MPXV7025GC6U Overview
A pressure sensor is a transducer that converts an applied pneumatic or hydraulic pressure into a proportional electrical signal. Within the broader sensor taxonomy, the MPXV7025GC6U is a board-mount MEMS pressure sensor -> piezoresistive transducer -> signal-conditioned analog sensor -> MEMS device -> semiconductor. The 'compound' rating means the device measures both positive gauge pressure (up to +25 kPa above atmospheric) and negative vacuum pressure (down to -25 kPa below atmospheric) on a single output span, which is essential for applications such as medical vacuum systems, HVAC, and engine manifold monitoring where the pressure can swing across atmospheric reference.
Key features include on-chip signal conditioning, temperature compensation between 0 °C and 85 °C, and calibration that eliminates the need for external trim components. The 5 V typical supply with ratiometric output (VOUT/VCC scaling) provides 90 mV/kPa nominal sensitivity over the full ±25 kPa span, plus ±5 % accuracy after calibration. The patented single-element transducer combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing to deliver stable, repeatable performance with long-term drift typically below 1 % per year.
Typical applications include HVAC variable-air-volume (VAV) controllers, medical respiratory and vacuum equipment, industrial process control, altimeters and variometers, and engine manifold absolute/relative pressure sensing. The 8-SMD top-port package simplifies pneumatic connection via 3.18 mm (0.13 in) tubing while keeping the PCB-side reflow-compatible.
When designing with this device, ensure that the analog supply (VCC) is well decoupled with a 100 nF ceramic capacitor placed within 5 mm of the supply pin, and avoid sharp tubing bends at the axial port to prevent stress on the package. The output is ratiometric to VCC, so any noise on the 5 V supply will translate directly into output noise — use a low-noise LDO for best results.

Typical Applications
MPXV7025GC6U is suitable for 6 applications: HVAC Variable Air Volume (VAV) Control, Medical Vacuum and Respiratory Equipment, Engine Manifold Pressure / MAP Sensing, Industrial Process Control and Pneumatic Systems, Altimeter / Variometer for UAVs and Model Aircraft, Water-Level / Liquid Depth Sensing.
HVAC Variable Air Volume (VAV) Control
The MPXV7025GC6U's ±25 kPa compound range is well-matched to HVAC duct static pressure measurement, where differential pressures across VAV boxes and dampers typically swing between -250 Pa and +250 Pa on either side of atmospheric reference. The compound output span (0.2 V to 4.7 V) lets one ADC channel capture both supply and return duct conditions. With 90 mV/kPa sensitivity and ±5 % accuracy, the sensor provides 25 Pa resolution when read by a 12-bit ADC over 5 V, sufficient for closed-loop damper control. The SOP-8 top-port package accepts standard 3.18 mm pneumatic hose for direct duct tap mounting, simplifying installation versus remote-diaphragm transducers.

Medical Vacuum and Respiratory Equipment
Medical suction devices, CPAP machines, and respiratory monitors routinely measure vacuum pressures in the -5 kPa to -25 kPa range, which falls directly inside the MPXV7025GC6U's compound measurement window. The ratiometric analog output (0.2 V to 4.7 V) simplifies interface to medical device MCUs with built-in ADCs, while on-chip temperature compensation across 0 °C to +85 °C covers body-temperature and ambient-clinical scenarios. The medical-grade accuracy (±5 %) is sufficient for therapy delivery monitoring where ±1 kPa precision is acceptable. Use a sterile-filtered pneumatic line to the axial port to prevent contamination of the sensor die.
Recommended
Engine Manifold Pressure / MAP Sensing
Engine manifold absolute pressure (MAP) sensors in light-engine and small-engine applications measure vacuum during intake stroke (down to -80 kPa for full throttle) and modest boost pressure (up to +25 kPa for naturally aspirated engines). The MPXV7025GC6U's ±25 kPa compound range suits small-engine and naturally-aspirated automotive monitoring. Its 0.2 V to 4.7 V ratiometric output interfaces directly to engine ECUs with 5 V ADC rails. For full-throttle-down (high-vacuum) engines, use a wider-range MAP sensor; for boost applications beyond 25 kPa, select a different pressure range. The SOP-8 surface-mount package supports automated PCB assembly on ECU boards.
Recommended
Industrial Process Control and Pneumatic Systems
Industrial pneumatic systems operate at pressures up to ±25 kPa in vacuum-pick-and-place equipment, vacuum-conveying lines, and low-pressure process gas monitoring. The MPXV7025GC6U's compound range covers both vacuum pickup (-25 kPa typical) and positive-pressure blow-off (+25 kPa) on a single sensor output. The 8-SMD gull-wing package withstands industrial vibration environments when mounted with through-hole supports at the pneumatic port. The 0-5 V analog output integrates with PLC analog input modules (4-20 mA conversion via a parallel shunt resistor) and SCADA systems, while the on-chip calibration eliminates field-trimming overhead.
Recommended
Altimeter / Variometer for UAVs and Model Aircraft
The MPXV7025GC6U's ±25 kPa compound range is well-matched to low-altitude UAVs, model aircraft, and weather balloons where altitude changes of 100 m to 2000 m produce small barometric pressure swings (1 kPa ≈ 8 m altitude). The 90 mV/kPa sensitivity provides 1.6 mV per meter of altitude, which a 12-bit ADC over 4.096 V reference resolves to ~1 m. The compact 8-SMD package fits in size-constrained UAV avionics bays, and the axial top-port accepts a static-pressure tube for pitot-static reference. For high-altitude (>3000 m) or large-altitude-range drones, choose a wider-range sensor (e.g., 30-110 kPa absolute) for full-scale coverage.
Recommended
Water-Level / Liquid Depth Sensing
Hydrostatic water-level sensors for tanks, reservoirs, and rainwater harvesting use small positive pressures (up to +25 kPa for 2.5 m of water column) measured relative to atmospheric reference on the back side of the sensor. The MPXV7025GC6U measures the positive half of its compound range to provide 0-2.5 m water column with 25 mm resolution at 12-bit ADC. The axial top port accepts a waterproof tube routed to the submerged measurement point, with a vent line on the back side to reference atmospheric pressure. The SOP-8 surface-mount package must be potted in a sealed housing for outdoor/waterproof deployment.

Design Notes
The MPXV7025GC6U output is ratiometric to VCC, so a noisy 5 V supply directly couples into the pressure reading. Place a 100 nF X7R ceramic decoupling capacitor within 5 mm of the VCC pin, and feed the device from a low-noise LDO (such as TPS7A4701 or MIC5504) rather than directly from a switching converter. A pi-filter (10 ohm + 100 nF + 10 uF) on VCC improves PSRR by an additional 20 dB at 100 kHz.
Keep the analog output trace short and routed away from digital lines, switching converter inductors, and high-current traces. Use a ground plane on layer 2 of the PCB directly under the sensor; avoid routing any signal traces on the layer directly beneath the sensor to minimize capacitive coupling into the output. The axial tube port must be mechanically anchored to the PCB to prevent stress on the package that could shift calibration — use a flexible silicone strain-relief at the port-tube interface.
Do not apply pressure beyond ±25 kPa — overpressure can permanently damage the MEMS die. Do not allow water, condensation, or conductive particles to enter the tube port; use a hydrophobic membrane filter (e.g., Goretex PTFE) at the port inlet for humid or outdoor applications. Do not bend the tube sharply at the port (radius of curvature should be >10 mm) as this mechanically biases the die and shifts the output. Do not reflow-solder above 260 °C peak for more than 30 seconds — the SOP-8 package is rated for MSL-3 handling.
