MPXV7025GP - ±25kPa Compound Pressure Sensor, 8-SMD | NXP Semiconductors
MPN： MPXV7025GP ✓ 啟用中MPXV7025GP 概覽
A pressure sensor is a transducer that converts an applied pressure into a proportional electrical signal, typically voltage. The MPXV7025GP belongs to the integrated silicon pressure sensor family (piezoresistive transducer -> MEMS pressure sensor -> pressure sensor -> sensor IC), combining a micromachined silicon diaphragm with on-board ASIC conditioning. This integration eliminates the need for external amplification or temperature compensation circuitry, simplifying design-in for engineers.
Key features include a compound pressure range allowing both positive and vacuum measurement, a ratiometric analog output suitable for 5V supply systems, and factory calibration that removes user-side trimming. The device operates over a wide supply voltage with low power consumption and provides temperature-compensated output across its specified operating range. Its integrated signal chain produces a clean analog voltage that maps linearly to applied pressure, reducing software overhead.
The MPXV7025GP is built using NXP's proprietary MEMS piezoresistive technology combined with a bipolar op-amp signal-conditioning ASIC. The Wheatstone bridge formed by implanted resistors on the silicon diaphragm produces a differential millivolt signal that is amplified, offset-corrected, and temperature-compensated to deliver a ground-referenced 0.2 V to 4.7 V swing. This single-chip integration dramatically improves noise immunity compared to discrete transducer designs.
Typical applications include HVAC air-flow monitoring, respiratory equipment, barometric compensation for altimeters, process control systems, and medical vacuum/pressure monitoring. The compound range enables measurement in systems that see both pressure and vacuum.
When designing with this part, decouple the VCC pin with a 100 nF ceramic capacitor placed close to the sensor leads. The output is ratiometric to VCC, so for highest accuracy, ADC read the regulator should share the same supply rail as the sensor or use a precision reference.

典型應用
MPXV7025GP 適用於 7 應用s: HVAC Air-Flow Monitoring, Medical Respiratory / Ventilator Equipment, Barometric / Altitude Compensation, Industrial Process Control, Appliance Pressure Sensing, Pneumatic System Monitoring, Automotive Sensor Modules.
HVAC Air-Flow Monitoring
The MPXV7025GP's ±25 kPa compound pressure range directly spans the duct-pressure swings seen in HVAC variable-air-volume (VAV) boxes and filter-monitoring stations. Its 0.2 V to 4.7 V ratiometric output interfaces cleanly to a 5 V MCU ADC without external op-amp gain, reducing BOM count. The integrated temperature compensation holds accuracy across the -40C to +125C industrial range, important for rooftop and basement equipment. Compared to discrete transducers, the on-chip ASIC eliminates manual calibration, accelerating design-in for HVAC controller modules and BACnet/Modbus building-automation systems.

Medical Respiratory / Ventilator Equipment
The MPXV7025GP's ±25 kPa compound range maps precisely to the inspiratory and expiratory pressures encountered in CPAP, BiPAP, and ventilator circuits. The on-chip signal conditioning reduces PCB real estate - critical for compact medical wearables and disposables. Ratiometric output ensures consistent readings even as battery voltage sags during portable use. The 8-SMD gull-wing package supports automated SMT assembly, lowering per-unit manufacturing cost. Designers should add an external LPF to limit pneumatic-circuit noise aliasing into the ADC and follow IEC 60601-1 isolation requirements for patient-contact circuits.
推薦
Barometric / Altitude Compensation
Used as a low-cost differential sensor, the MPXV7025GP enables differential pressure sensing across orifice plates to derive flow in gas meters and portable altimeters. The compound range handles both positive flow and back-pressure conditions in pump-driven systems. Its wide operating temperature range allows deployment in outdoor weather stations and drone altitude-aiding modules. The 5 V ratiometric output pairs naturally with common MCU ADC references. For high-altitude drones, pair with an absolute barometric sensor to combine differential and absolute readings.
推薦
Industrial Process Control
In process-control cabinets and PLC analog input modules, the MPXV7025GP monitors pump differential pressure, filter clogging, and tank-level hydrostatic head. The 8-SMD package slides into standard SMT analog-input footprints, and the ratiometric output simplifies scaling in the PLC firmware. Industrial users benefit from the -40C to +125C operating range and on-chip temperature compensation, which removes the periodic recalibration required by uncompensated transducers. Add a TVS diode across the supply for harsh factory-floor EMI environments.
推薦
Appliance Pressure Sensing
White goods such as washing machines and dishwashers use the MPXV7025GP to monitor water-level pressure, drain-pump back-pressure, and steam-cleaner pressures. The integrated signal conditioning eliminates the analog-front-end circuitry typical in MCU-based appliance designs, lowering total BOM and reducing firmware complexity. The single side-port barbed stem accepts standard silicone tubing used in appliance plumbing. Compared to electromechanical pressure switches, the analog output enables soft-start algorithms and predictive-maintenance diagnostics in connected appliances.
推薦
Pneumatic System Monitoring
Compressed-air systems in factories use the MPXV7025GP to monitor line pressure, leak detection, and actuator load feedback. The 0.2 V to 4.7 V output maps cleanly to industrial 0-10 V or 4-20 mA transmitter modules after scaling. The 8-SMD gull-wing footprint supports high-density IO modules. For hazardous-area pneumatic systems, isolate the sensor signal with a barrier amplifier to satisfy intrinsic-safety requirements. Compared to switches, the analog reading provides trend data for IIoT predictive-maintenance platforms.
推薦
Automotive Sensor Modules
Beyond HVAC, the MPXV7025GP is used in automotive cabin-air-quality and fuel-vapor system monitoring, where the wide temperature range and rugged SMD package are valued. The ratiometric output interfaces directly to automotive MCUs running at 5 V. For under-hood deployment, ensure the housing provides adequate thermal isolation from engine bay temperatures. Pair with NXP's S32K MCUs for a complete automotive-grade signal chain.

主要差異化特點

- On-chip temperature compensation and factory calibration (對比MPXV7002DP)
設計說明
The MPXV7025GP is ratiometric: its 0.2 V to 4.7 V output is proportional to VCC. For maximum accuracy, derive the MCU ADC reference voltage from the same 5 V LDO that powers the sensor. Place a 100 nF ceramic decoupling capacitor as close as possible to VCC (pin 1) and GND (pin 3) to suppress switching-noise injection from upstream regulators. Estimated: at 5 V supply and 7 mA quiescent current (typical MPX family), power dissipation is ~35 mW - negligible thermal management needed.
Route the sensor output trace away from switching-converter nodes and high-current traces; add a small RC low-pass filter (10 kohm + 100 nF) at the ADC input to suppress pneumatic-coupled noise and ADC switching transients. Keep the side-port tube stub as short as practical to minimize acoustic resonance in the pneumatic path. Place the sensor with the port facing away from vibration sources to reduce piezo-coupling to the MEMS diaphragm.
Do not apply pressure exceeding the rated ±25 kPa range - overload can permanently damage the MEMS diaphragm. Do not connect the NC pins; per the NXP datasheet, leaving them floating is correct, and tying them to VCC can cause internal latch-up. Do not use a separate supply for the sensor and the ADC reference, as this breaks ratiometric tracking and degrades accuracy. For wash-down or condensing environments, seal the side port with a moisture-resistant filter to prevent diaphragm corrosion.
