MPXV7007GC6U - ±7kPa Compound Pressure Sensor 5V SOP-8 | NXP
MPN： MPXV7007GC6U ✓ 啟用中MPXV7007GC6U 概覽
A pressure sensor (also called a pressure transducer) is a device that converts an applied pneumatic or hydraulic pressure into a measurable electrical signal. Within the sensor taxonomy, the MPXV7007GC6U belongs to the MEMS piezoresistive family, where silicon strain gauges diffused into a diaphragm change resistance as the diaphragm flexes under pressure. These gauges are typically Wheatstone-bridge configured on-chip, with integrated signal conditioning (amplification, offset, and temperature compensation) so that the output is linear, calibrated, and ready to be read by a microcontroller ADC.
Key specifications include a pressure range of ±7 kPa with full-scale span of 4.0 V (typical), an operating temperature range of -40 °C to +125 °C, an accuracy of ±1.5 %VFSS (max) over the compensated range of 0 °C to +85 °C, a supply current of typically 7 mA, and ESD protection of 2 kV HBM on the pressure port and 200 V on the signal pins. The device uses on-chip temperature compensation and calibration, eliminating external trimming in production. The SOP-8 surface-mount package simplifies PCB assembly and is compatible with standard SMD pick-and-place lines.
Typical applications include HVAC variable-air-volume (VAV) controllers, medical respiratory instruments (spirometers, ventilators), industrial process control, altitude and weather-station instrumentation, and consumer appliances such as washing-machine water-level monitors. The compound (-7 to +7 kPa) range is particularly valuable for measuring both vacuum and positive pressure relative to atmospheric reference, enabling bidirectional flow sensing across fans, and filter differential-pressure monitoring in ventilation ducts. When designing with this device, place a 0.1 uF decoupling capacitor close to the supply pin, keep the pressure-port tubing short to minimize pneumatic resonance, and protect the port from condensation and direct water exposure using a barrier membrane when needed.

典型應用
MPXV7007GC6U 適用於 6 應用s: HVAC Variable Air Volume (VAV) Control, Medical Respiratory / Spirometer Sensing, Filter Differential Pressure Monitoring, Industrial Process Vacuum Monitoring, Consumer Appliance Water-Level Sensing, Barometric and Altitude Instrumentation.
HVAC Variable Air Volume (VAV) Control
The MPXV7007GC6U is widely deployed in commercial-building HVAC variable-air-volume (VAV) damper controllers, where the bidirectional ±7 kPa range directly measures duct airflow differential. Its compound sensing capability allows detection of both pressure drop across filters (vacuum) and supply-side positive pressure, enabling a single sensor to monitor two pneumatic domains. The 5 V ratiometric output feeds a standard 10-bit or 12-bit microcontroller ADC, and the integrated axial port simplifies duct tap installation with 3.17 mm tubing.
推薦
Medical Respiratory / Spirometer Sensing
In medical respiratory equipment such as spirometers, ventilators, and CPAP/BiPAP machines, the MPXV7007GC6U measures pressure swings across the breathing circuit with high linearity (±1.5 %VFSS) and stable 0 °C to +85 °C temperature behavior. The compound ±7 kPa window is wide enough to capture peak inspiratory and expiratory pressure drops without saturation. The on-chip calibration eliminates the trim step that hospital-grade OEMs would otherwise have to perform on every board, accelerating time-to-market for FDA-cleared devices.
推薦
Filter Differential Pressure Monitoring
The MPXV7007GC6U provides reliable across-filter vacuum in HEPA-filter and dust-collector differential-pressure transmitters. The bidirectional range yields a measurable voltage delta as the filter loads with particulates and the upstream-to-downstream pressure drop grows toward -7 kPa. Maintenance personnel can therefore track clogging trends from a calibrated 0.5 to 4.5 V output without recalibration. The SOP-8 SMD package simplifies mounting inside the filter-housing electronics enclosure.
推薦
Industrial Process Vacuum Monitoring
In industrial vacuum-pump and pick-and-place suction monitoring, the MPXV7007GC6U converts the pneumatic vacuum applied to a suction nozzle into a calibrated analog voltage readable by a 5 V PLC or microcontroller. The ±7 kPa compound range covers both atmospheric (0 V = 0 kPa = ambient) and full-vacuum operating points. The 5 V supply and small SMD package simplify integration into modular industrial sensor heads. ESD-withstand of 2 kV on the port protects against static-charge-induced failure in factory environments.
推薦
Consumer Appliance Water-Level Sensing
Consumer washing machines and dishwashers use the MPXV7007GC6U for water-level and air-pressure-trap differential-pressure measurement. The pressure chamber is sealed against the drain trap, and the head pressure of water inside the chamber is detected via the SOP-8 axial port. The integrated calibration removes per-board factory trim, reducing assembly cost. The 5 V ratiometric output feeds directly into the appliance microcontroller's ADC, which uses factory-stored compensation to compute water volume.
推薦
Barometric and Altitude Instrumentation
Although primarily a compound sensor, the MPXV7007GC6U can be used for low-resolution barometric and altitude-sensing applications where ±7 kPa is sufficient for indoor weather stations or HVAC outdoor-air measurement. The 0 °C to +85 °C compensated range covers most outdoor enclosures. The SOP-8 surface-mount footprint simplifies integration into compact weather-station PCBs, and the ratiometric output drives an ADC without requiring a precision voltage reference.

主要差異化特點
- Bidirectional compound ±7 kPa range in single SOP-8 (對比MPXV4006GC6T1)
- Industry-standard axial top port with 3.17 mm tubing compatibility (對比MPXV4115VC6U)
- Wider pressure window vs MPXV7002 family (對比MPXV7002GC6T1)
設計說明
Estimated: at 5 V supply and 7 mA typical supply current, the MPXV7007GC6U draws about 35 mW of continuous power. The two VCC pins (3 and 4) and two GND pins (2 and 5) must each be tied together on the PCB. Place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VCC pins; an additional 1 uF bulk capacitor improves immunity against digital supply noise.
Route analog output traces away from switching power and high-current digital traces to prevent noise coupling into the ratiometric ADC reading. Use a ground plane under the sensor footprint to shield the silicon die from PCB noise. The axial pressure port should be mounted at the highest point of the PCB if condensate accumulation is a concern.
Do not apply pressure beyond -7 to +7 kPa; bursts can rupture the silicon diaphragm and permanently damage the sensor. Avoid water ingress into the axial port - install a barrier membrane such as Gore-Tex vented membrane if moisture exposure is possible. The output is ratiometric, meaning an unstable 5 V supply becomes an unstable pressure reading. A clean 5 V LDO such as a TPS7A4533 or AP2112 is recommended upstream.
