MPVZ5004GW7U - 3.92kPa Pressure Sensor, 5V, SOP-8 | NXP
MPN： MPVZ5004GW7U ✓ 啟用中MPVZ5004GW7U 概覽
A pressure sensor (also called a pressure transducer) is a device that converts an applied pressure into an analog electrical signal, typically voltage. Piezoresistive sensors rely on strain gauges whose resistance changes with mechanical deformation of a silicon diaphragm. Within the sensor hierarchy, MPVZ5004GW7U sits inside the MEMS (micro-electromechanical systems) family, which itself is a subset of sensors and transducers. These conditioned parts include amplifier, temperature-compensation, and calibration stages on-die, so they connect directly to a microcontroller ADC without external analog front-end components.
Key features include a full-scale span of 3.92 kPa, an output span of approximately 4.0 V (from 1 V at 0 kPa to 4.9 V at 3.92 kPa, assuming 5 V excitation), ratiometric output that tracks supply voltage, and an operating temperature range of 0 °C to 85 °C (per the device family datasheet). The 5.59 mm male tube port accepts a flexible hose and gives the part its "GW" (gauge, with port) package designation, distinguishing it from surface-mount leadless siblings.
The transducer architecture uses a single-crystal silicon diaphragm with an implanted piezoresistive Wheatstone bridge. A first-stage differential amplifier and temperature-correction network run on the same die, producing a calibrated transfer function near VOUT = 5 V × (0.2 + P / 4.0 kPa) over the compensated band. Compared with ceramic-capacitive or discrete strain-gauge designs, this integration reduces calibration effort at end-of-line and improves long-term drift.
Typical applications include medical respiratory airflow measurement (CPAP flow sensing), HVAC variable-air-volume (VAV) boxes, weather stations, altimeters, and process-control manifolds. The vented gauge reference simplifies absolute-pressure correction in patient monitoring. Designers should account for the gauge-port orientation and ensure the hose connection is leak-tight; see the manufacturer datasheet for derating curves above 85 °C and recommended PCB footprint when hand-soldering.

典型應用
MPVZ5004GW7U 適用於 6 應用s: Medical CPAP Airflow Monitoring, HVAC Variable-Air-Volume (VAV) Box, Weather Station and Altimeter, Industrial Process Control Manifold, Respiratory Spirometer, Air Quality / IAQ Monitor.
Medical CPAP Airflow Monitoring
The MPVZ5004GW7U is ideal for CPAP machine airflow monitoring where the 0 to 3.92 kPa range matches typical patient breathing-circuit pressures. The 5.59 mm male tube port accepts a flexible silicone hose without custom fixturing, and the on-chip temperature compensation eliminates the analog drift that would otherwise corrupt breath-trigger detection. Connecting VOUT directly to a microcontroller ADC running at 5 V, the ratiometric 1.0 V to 4.9 V swing gives ~1.0 V/kPa sensitivity - sufficient to resolve tidal-volume waveforms with 10-bit ADC resolution. Compared with discrete strain-gauge designs, the integrated amplifier and calibration cut BOM cost and PCB area by more than 50 %.

HVAC Variable-Air-Volume (VAV) Box
The MPVZ5004GW7U's 3.92 kPa full-scale matches the typical static pressure drop across VAV box damper elements in commercial HVAC systems. The vented-gauge reference auto-compensates for ambient barometric pressure changes, so installers do not need altitude calibration. The analog ratiometric output feeds a 0 to 10 V building-automation controller via a simple op-amp level shifter, and the integrated calibration eliminates the per-board trim pot that legacy VAV transducers required. At 4 mA typical supply current, the sensor is suitable for 4 to 20 mA loop-powered panels when paired with a current-loop transmitter.
推薦
Weather Station and Altimeter
For low-cost weather stations measuring barometric trends, the MPVZ5004GW7U provides a calibrated analog pressure reading that, combined with an absolute-pressure reference such as MPL3115A2, yields accurate altitude estimation. The 3.92 kPa full scale is too narrow for direct barometric use but ideal for differential measurement across weather-station airflow channels (e.g. wind-tunnel or aspirated radiation shield). The 0 to 85 °C operating range covers outdoor enclosures from temperate to tropical climates, and the ratiometric 5 V output simplifies battery-powered designs using a 5 V boost converter.
推薦
Industrial Process Control Manifold
In process-control manifolds measuring filter differential pressure, the MPVZ5004GW7U detects pressure drops from 0 to 3.92 kPa with on-chip temperature compensation that eliminates thermal-induced false alarms. The 8-DIP through-hole package is well suited to industrial control PCBAs where through-hole components dominate, and the 5.59 mm tube port accepts standard pneumatic tubing without adapters. The ratiometric output integrates directly with 5 V PLC analog inputs, and the 0 to 85 °C operating range covers factory-floor environments with mild thermal stress.
推薦
Respiratory Spirometer
Handheld spirometers use the MPVZ5004GW7U to measure exhaled flow differential pressure across a Fleisch pneumotach. The 0 to 3.92 kPa range captures peak expiratory flow at the typical ±0.4 kPa spirometry test envelope with good resolution, and the integrated amplifier eliminates the analog-front-end calibration step required by legacy differential-pressure sensor modules. The vented-gauge reference accommodates ambient barometric variation between clinic and home-use environments without requiring altitude correction in firmware.
推薦
Air Quality / IAQ Monitor
Indoor air quality monitors measuring HVAC filter loading use the MPVZ5004GW7U to track pressure drop across mechanical filters. As filters load, the differential pressure rises into the 0 to 3.92 kPa range, and the sensor's ratiometric output drives a filter-replacement alert LED. The low 4 mA supply current and small through-hole footprint suit battery-powered Wi-Fi IAQ nodes that mount in HVAC ducts, and the integrated temperature compensation eliminates false alerts caused by day/night thermal cycling of the duct.

設計說明
Power the MPVZ5004GW7U from a low-noise 5 V LDO such as the NXP MC78M05 or the TI TPS7A47xx family rather than directly from a switching converter. A clean supply is critical because the output is ratiometric - any 100 mV ripple on VCC couples directly into the pressure reading. Place a 100 nF ceramic bypass capacitor within 5 mm of the VS pin (pin 4 or pin 5) and a 10 µF bulk capacitor on the supply rail. Estimated: with VS ripple of 50 mV pk-pk, expect kpi - 0.05 V of additional readout error.
Route the analog VOUT trace away from digital switching nodes and motor driver traces. Keep the trace short (less than 25 mm) and place the MCU ADC input bypass capacitor (typically 10 nF) close to the ADC pin, not the sensor. The vented-gauge reference port on the GW7U must remain exposed to ambient atmosphere; do not seal the port with conformal coating. For airflow measurements, orient the tube so condensate cannot pool in the port.
Do not apply more than 5.25 V to VS - permanent damage to the on-chip amplifier will result. Do not exceed the published overpressure rating (typically 25 kPa, three times full-scale); verify from the NXP datasheet before designing mechanical fixturing. Do not assume the output at 0 kPa is exactly 0 V - it is approximately 1.0 V, which must be subtracted in firmware. Do not operate below 0 °C or above 85 °C without consulting the manufacturer for derating.
