MPXV5004GC6U Overview
What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a MEMS device in which implanted strain gauges on a silicon diaphragm change resistance proportionally to applied differential pressure. The MPXV5004 belongs to the monolithic silicon pressure sensor family, sitting in the hierarchy: MEMS pressure sensor -> piezoresistive transducer -> pressure sensor -> sensor IC -> semiconductor. It is designed to interface directly to an ADC input of a microcontroller or microprocessor without external signal conditioning.
Key features include a 4.75 V to 5.25 V supply range, low pressure range (0 to 3.92 kPa) ideal for airflow and liquid-level sensing, ±2.5% accuracy (typical) over 10 °C to 50 °C, ratiometric analog output that compensates for supply variation, and on-chip temperature compensation from 10 °C to 60 °C. The 8-SMD gull-wing package is surface-mountable and includes an integrated port for direct pneumatic connection.
Architecturally, the device combines a micromachined silicon diaphragm with thin-film metallization and bipolar signal-conditioning circuitry to produce a calibrated voltage output proportional to pressure. The piezoresistive bridge is laser-trimmed at wafer level for offset and span, eliminating the need for external passive trimming networks. The vented-gauge configuration references the low-side pressure to ambient via the package, simplifying hose routing in medical and HVAC applications.
Typical applications include medical respiratory airflow monitoring (CPAP, ventilators, spirometers), HVAC variable-air-volume (VAV) controllers, industrial process control, low-differential gas flow metering, water-column level detection, and appliance pressure sensing. Its small size and analog output also make it well suited to portable battery-powered instruments where an MCU ADC is available.
When designing with the MPXV5004GC6U, place 0.1 µF supply decoupling as close to VCC and GND pins as possible and route the analog output through a low-pass RC filter (typically 1 kΩ and 0.01 µF) to suppress high-frequency noise from the upstream switching converter. Account for the ratiometric output when designing the ADC reference: a stable 5 V supply is required for absolute accuracy; if the supply drifts, the output drifts proportionally.

Typical Applications
MPXV5004GC6U is suitable for 6 applications: CPAP / Ventilator Airflow Monitoring, HVAC Variable Air Volume (VAV) Control, Spirometer Flow-Head Sensing, Cleanroom / Lab Differential Pressure, Water-Column / Tank Level Sensing, Appliance Pressure / Vacuum Monitoring.
CPAP / Ventilator Airflow Monitoring
The MPXV5004GC6U measures differential pressure across a CPAP flow element to derive patient airflow. Its 0 to 3.92 kPa range maps directly to clinical flow-head pressures (~0 to 400 mm H2O). Ratiometric 1 V to 4.9 V output drives a microcontroller ADC with no analog front-end. On-chip compensation from 10 °C to 60 °C handles breathing-circuit thermal variation, while the top port accepts standard 0.13 in tubing for direct hose connection. Used in CPAP, BiPAP, and anesthesia ventilators.
Recommended
HVAC Variable Air Volume (VAV) Control
In VAV boxes, the MPXV5004GC6U senses duct differential pressure to modulate damper position. The 0 to 3.92 kPa range matches typical duct static pressure spans (~0 to 16 in H2O). Ratiometric 5 V operation lets the sensor share a building-automation supply rail, while the 8-SMD surface-mount package sits directly on a controller board. Accuracy ±2.5% over 10 °C to 50 °C holds across conditioned mechanical spaces, and the top port simplifies pneumatic plumbing to the duct pickup tube.
Recommended
Spirometer Flow-Head Sensing
Handheld spirometers use the MPXV5004GC6U to detect pressure drop across a Fleisch-type flow head. The 0 to 3.92 kPa range maps to flow rates up to ~15 L/s with appropriate flow element. Ratiometric output cancels supply drift in battery-powered designs. Top-side port accepts disposable mouthpieces directly. Low supply current (single-digit mA) preserves handheld battery life, and the SOP-8 SMD package supports high-volume automated assembly.
Recommended
Cleanroom / Lab Differential Pressure
Cleanrooms require monitoring of small pressure differentials between adjacent rooms to maintain contamination gradients. The MPXV5004GC6U's 0 to 3.92 kPa range (~0 to 400 mm H2O) covers the typical 12.5 Pa to 25 Pa cascade requirement when used in parallel multi-port arrangements. The vented-gauge reference eliminates the need for a separate atmospheric reference line. Surface-mount SOP-8 enables integration into a wall-mount transmitter PCB, and the ratiometric 1 V to 4.9 V output feeds a building-automation analog input module directly.
Recommended
Water-Column / Tank Level Sensing
The MPXV5004GC6U can detect low water columns in tanks, reservoirs, and drip trays via a bubbler-type pneumatic level sensor. Each 1 kPa equals ~10 cm H2O, so the 0 to 3.92 kPa range measures up to ~40 cm column height. The top port connects directly to the air-pump tubing, and the vented-gauge design references ambient pressure automatically. Low-pressure air-flow sensors avoid corrosion that would damage immersed transducers, making the MPXV5004GC6U ideal for non-contact chemical or sanitary level sensing.
Recommended
Appliance Pressure / Vacuum Monitoring
In vacuum cleaners, steam irons, and sealed-cooking appliances, the MPXV5004GC6U monitors internal pressure or vacuum for control feedback. The 0 to 3.92 kPa range covers suction-side measurements up to ~40 mbar, well-suited for steam-iron steam-chamber and vacuum-cleaner hose-side sensing. The SOP-8 gull-wing package is reflow-solderable for high-volume appliance manufacturing, and the 1 V to 4.9 V ratiometric output drives a low-cost appliance MCU without signal conditioning. On-chip temperature compensation handles the wide thermal environments of household appliances.

Key Differentiators
- Industry-standard MPxx5004 pinout and footprint (vs MPXV5004GC7U)
- Top-side port with standard 0.13 in tubing (vs MPXV5004GP)
- Ratiometric analog output for ADC-direct drive (vs MPXV5004DP)
Design Notes
Place a 0.1 µF ceramic decoupling capacitor as close as possible to the VCC pins (1 and 2) and GND (pin 3). For systems with switching regulators upstream, add a 10 µF bulk capacitor on the 5 V rail feeding the sensor to suppress switching ripple that would otherwise couple into the ratiometric analog output.
Route the analog output (pin 4) away from switching converter inductors and high-current traces. Add a first-order RC low-pass filter (1 kΩ and 0.01 µF typical) at the ADC input to attenuate switching noise. Maintain a stable 5 V supply to the sensor because the output is ratiometric — a 1% drift in VCC produces a 1% error in the pressure reading.
Do not apply pressure beyond the rated overpressure limit, and never expose the sensor to condensing humidity or liquid ingress through the top port unless the application uses a pneumatic interface (tubing, hydrophobic filter, bubbler). The vented-gauge reference routes ambient pressure through the package, so blocking the vent will cause drift with barometric change. Also, calibrate the ADC reference against the sensor supply, not against an independent rail, to fully exploit the ratiometric output.
