MPVZ7025DP - ±3.63 PSI Differential Pressure Sensor, 8-BSOP | NXP
MPN： MPVZ7025DP ✗ 停產MPVZ7025DP 概覽
A board-mount pressure sensor is a transducer that converts applied gas or air pressure into a proportional electrical signal, generally an analog voltage, current (4-20 mA), or digital (I2C/SPI) value. Within the sensor family hierarchy, the MPVZ7025DP sits at: pressure sensor -> board-mount pressure sensor -> piezoresistive pressure sensor -> differential pressure sensor -> MEMS silicon pressure sensor. It belongs to the broader Sensors product category and is used whenever a system must measure the pressure difference between two points rather than absolute pressure referenced to vacuum.
Key specifications include ±25 kPa operating pressure range, 0.2 V to 4.7 V analog output swing, on-chip ASIC signal conditioning, and 5 V typical supply. The transducer uses a monolithic silicon diaphragm with implanted piezoresistive bridges laser-trimmed for offset and span, then calibrated over temperature for accuracy. The 8-BSOP Dual Ports Same Side package supports surface-mount assembly and simplifies hose connection for differential flow sensing.
Typical applications include HVAC variable-air-volume (VAV) damper control, medical respiration monitoring, industrial flow sensing, altitude and barometric trend instrumentation, and consumer appliance pressure feedback. Its differential port style lets designers reference one side to ambient while measuring on the other, or compare two points in a flow stream.
When integrating the MPVZ7025DP, ensure each port connects to a clean, dry, non-corrosive gas source and add a 100 nF decoupling capacitor close to the supply pin. The output is ratiometric with Vcc, so use a stable, low-noise 5 V reference ADC to preserve accuracy across the 0.2 V to 4.7 V output span.

典型應用
MPVZ7025DP 適用於 6 應用s: HVAC Variable Air Volume Control, Medical Respiration and Flow Monitoring, Industrial Differential Flow Sensing, Barometric Trend and Altitude Instrumentation, Consumer Appliance Pressure Feedback, Pneumatic System Leak Detection.
HVAC Variable Air Volume Control
The MPVZ7025DP suits HVAC Variable Air Volume (VAV) box control where the controller must measure the differential pressure across a flow restriction or orifice plate to compute airflow in cubic feet per minute. The ±25 kPa bidirectional range covers typical duct static-pressure spans, while the 0.2 V to 4.7 V analog output can be wired directly to a 5 V ADC on the building-automation controller. The dual same-side port style simplifies tubing to the two duct pickup points and the on-chip temperature compensation keeps accuracy stable across the 0-50 C HVAC environment.
推薦
Medical Respiration and Flow Monitoring
In medical respiration circuits, ventilator machines, and CPAP/BiPAP flow paths, the MPVZ7025DP measures the differential pressure across a flow element to compute instantaneous and tidal volumes. The ±25 kPa span is well above the pressures encountered in patient circuits, giving safety margin and linearity. The on-chip calibration removes the need for external op-amps, which is critical for compact, low-BOM medical electronics. Designers should connect ports via short, compliant tubing and isolate the sensor from liquid droplets with a hydrophobic filter.
推薦
Industrial Differential Flow Sensing
The MPVZ7025DP is a fit for industrial differential flow meters, filter-status indicators, and pump-monitoring loops where the differential pressure between two points in a process line must be tracked continuously. The 0.2 V to 4.7 V ratiometric output pairs with industrial 5 V ADC front-ends and PLC analog modules. The 8-BSOP surface-mount package supports high-volume SMT assembly, and the dual same-side ports simplify the manifold or tubing harness. For higher pressure ranges, consider the MPXV5004 family; for lower, the MPXV5010DP.
推薦
Barometric Trend and Altitude Instrumentation
Weather stations, altimeters, and drone altitude-reference boards use the MPVZ7025DP to track slow-changing atmospheric differential pressure. While the ±25 kPa range is far wider than typical weather-scale changes, the high resolution and 0.2 V to 4.7 V output allow fine-grain trend capture after the signal is digitised. The on-chip temperature compensation preserves accuracy across outdoor thermal cycles. Designers typically use one port open to ambient and the other to a slow reference volume to avoid wind-induced noise.
推薦
Consumer Appliance Pressure Feedback
In washing-machine water-level sensors, dishwasher flow monitors, and smart-cooker pressure feedback, the MPVZ7025DP provides a low-cost calibrated differential pressure signal. The 8-BSOP SMT footprint and integrated conditioning reduce BOM and assembly cost in high-volume consumer products. The dual same-side port style mates with molded plastic tubing commonly used in appliance plumbing. For new designs the active MPXV7025DP should be specified to avoid the MPVZ7025DP's obsolete status.
推薦
Pneumatic System Leak Detection
Compressed-air pneumatic systems use the MPVZ7025DP to detect small leaks by sensing pressure decay between two monitored points or by measuring the differential pressure between a sealed volume and a reference. The ±25 kPa range covers typical shop-air pressures, and the 0.2 V to 4.7 V output connects directly to a microcontroller ADC for alarming or trending. The on-chip calibration removes drift concerns, which is important for long-term unattended monitoring applications.

主要差異化特點
- Differential dual-port variant of the MPXV7025 family (對比MPXV7025GP)

- On-chip signal conditioning and temperature compensation (對比Bare piezoresistive sensors)
設計說明
Power the MPVZ7025DP from a clean, low-noise 5 V rail because the output is ratiometric with Vcc. Place a 100 nF ceramic decoupling capacitor as close as possible to the Vcc pin, and add a bulk 10 uF capacitor on the same rail if the supply is shared with switching regulators. Ripple on Vcc directly translates to output error proportional to Vcc/Vcc_nominal.
Route the analog output away from digital switching traces, switching converters, and clock lines to avoid coupling noise. Use a ground plane under the analog path and keep the trace short to the ADC input. If long distances are required, buffer the output with a low-offset op-amp or use a differential ADC input pair to reject common-mode noise.
The MPVZ7025DP is obsolete and out of production; new designs should specify the active MPXV7025DP parametric substitute to avoid supply risk. The port style is differential dual-port; do not confuse with gauge MPXV7025GP. Apply only clean, dry, non-corrosive gases; for liquids or humid gases, add a hydrophobic filter and isolation manifold to protect the silicon diaphragm.
