MPXV5004DP Overview
What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a transducer that converts applied pressure into a change in resistance of diffused strain gauges on a silicon diaphragm, then conditions the resulting Wheatstone bridge imbalance into a proportional analog voltage. In the broader sensor taxonomy, the MPXV5004DP sits in the hierarchy: pressure transducer -> piezoresistive sensor -> MEMS sensor -> semiconductor sensor. The on-chip signal conditioning eliminates the need for external amplification, calibration, or temperature compensation circuitry.
Key features include a 1.0 V to 4.9 V ratiometric analog output spanning the 0-3.92 kPa range, 5 V typical supply operation (max 5.25 V), and an operating temperature range of 0°C to +85°C. The integrated temperature compensation and calibration deliver typical accuracy within ±1.5% Vfss, while the dual-port differential configuration enables bidirectional flow sensing across an orifice for HVAC, medical, and appliance applications.
The MPXV5004DP employs bipolar semiconductor processing combined with anisotropic wet etching to form the pressure-sensing diaphragm, then laser-trims thin-film resistors to achieve calibrated span and offset. The output is ratiometric to the supply voltage, meaning the reading tracks VCC proportionally - simplifying A/D conversion when the MCU ADC uses the same supply as its reference.
Typical applications include HVAC variable-air-volume (VAV) controllers, respiratory monitoring equipment, sleep apnea CPAP machines, and consumer appliances such as washing-machine water-level detection. The wide 0-3.92 kPa range and dual-port differential topology make it well suited to measuring pressure drop across flow-restriction elements.
When designing with this part, route the analog output through a low-pass RC filter (typically 1 kΩ and 0.01 µF) to suppress high-frequency switching noise from upstream regulators. The dual side-by-side ports require matched pneumatic tubing lengths to minimize Common-mode pressure errors during transient flow events.

Typical Applications
MPXV5004DP is suitable for 6 applications: HVAC Variable Air Volume (VAV) Control, CPAP and Sleep Apnea Machines, Washing Machine Water Level Detection, Respiratory Flow Measurement, Industrial Filter Pressure Drop Monitoring, Coffee Machine and Beverage Dispensing.
HVAC Variable Air Volume (VAV) Control
The MPXV5004DP fits HVAC VAV controller designs because its 0-3.92 kPa range matches the differential pressure drop across standard orifice plates used in duct airflow measurement, and its 1.25 V/kPa sensitivity delivers strong signal headroom above MCU ADC noise floors. The dual side-by-side ports simplify pneumatic plumbing with matched tubing runs, minimizing common-mode errors during damper transitions. Placed on the controller PCB near the MCU ADC with a 1 kΩ/0.01 µF output filter, it provides ratiometric 1.0-4.9 V output that tracks the 5 V supply and eliminates the need for a precision voltage reference. Unlike digital I²C pressure sensors, the analog output avoids bus contention on long cable runs to remote duct locations.
Recommended
CPAP and Sleep Apnea Machines
The MPXV5004DP is well suited for CPAP machine airflow and pressure monitoring because its 0-3.92 kPa range spans the breath-pressure amplitudes of adult therapeutic CPAP, and its ±1.5% Vfss accuracy after auto-zero enables reliable apnea-event detection. The calibrated analog output simplifies integration with the machine's main MCU ADC, eliminating digital bus overhead. Placed inline with the airflow path using dual pneumatic ports, it provides real-time pressure feedback for the blower control loop. The on-chip temperature compensation maintains accuracy across the 0°C to +85°C operating range that covers bedroom environment variations and internal chassis warm-up.
Recommended
Washing Machine Water Level Detection
The MPXV5004DP suits washing-machine water-level sensing because its low 0-3.92 kPa range maps directly to the small pressure changes generated by an air-trap tube connected to the drum. The 1.25 V/kPa sensitivity provides sufficient resolution to discriminate fill levels across 5-7 wash cycles. The 8-BSOP SMT package withstands the high-humidity laundry environment when the PCB is conformal coated, and the ratiometric output pairs well with cost-sensitive MCU ADCs. Unlike mechanical pressure switches, the MPXV5004DP provides continuous analog data enabling fuzzy-logic wash algorithms that optimize water and energy consumption.
Recommended
Respiratory Flow Measurement
The MPXV5004DP enables handheld spirometer and peak-flow meter designs because its calibrated 0-3.92 kPa differential range and 1 ms response time capture the dynamic flow transients of forced exhalation. The dual-port differential topology rejects ambient atmospheric pressure variations, which is critical for portable devices operating across elevations. The on-chip signal conditioning eliminates external op-amps that would otherwise consume PCB area and add drift. The 5 V supply draws only 10 mA, well within the budget of battery-powered handheld respiratory instruments, and the analog output integrates directly with low-cost MCUs lacking I²C peripherals.
Recommended
Industrial Filter Pressure Drop Monitoring
The MPXV5004DP fits industrial filter-clog detection systems because its differential 0-3.92 kPa range matches the pressure drop across clean HVAC intake filters and pre-filtration stages. The high 1.25 V/kPa sensitivity enables early detection of filter loading before airflow restriction triggers downstream alarms. Placed across the filter housing with two pneumatic taps, it provides a continuous health-monitoring signal to the building automation PLC. The robust 8-BSOP SMT package and 0°C to +85°C operating range handle industrial enclosure environments, while the ratiometric output tolerates long analog cable runs to remote filter locations.
Recommended
Coffee Machine and Beverage Dispensing
The MPXV5004DP is well suited to espresso machine brew-pressure monitoring because its 0-3.92 kPa range covers the lower end of pump-pressure profiles used in consumer espresso extraction, and its analog output enables real-time pressure curve display. The dual-port differential configuration rejects pump pulsations, providing a stable signal for closed-loop pressure control. The small 8-BSOP package fits compact consumer-appliance PCBs, and the on-chip calibration eliminates the trim pots required by legacy strain-gauge designs. The 5 V supply aligns with the standard power rails in espresso machine controllers.

Key Differentiators
- Highest sensitivity in the 8-BSOP MPxx family (vs MPXV4006DP)
- Single-rail 5 V supply with on-chip calibration (vs MP3V5004DP)
- Same 8-BSOP footprint as the broader MPxx5004/MPxx7002 family (vs MPXV5004GC6T1)
Design Notes
Place a 0.1 µF decoupling capacitor as close as possible to Pin 1 (VCC) and Pin 2 (GND). The analog output at Pin 3 should be routed with a guard trace connected to GND on both sides to suppress coupled switching noise from nearby digital signals. Recommended output filter is 1 kΩ series resistor plus 0.01 µF capacitor to GND, giving a 16 kHz -3 dB cutoff that attenuates MCU switching noise while preserving the 1 ms pressure response. Keep the analog trace short (under 50 mm) to minimize pickup of adjacent digital or RF traces. Severity: recommended.
The MPXV5004DP output is ratiometric to VCC, meaning the absolute voltage scales linearly with supply voltage. To maximize ADC accuracy, use the same 5 V rail as the MCU's ADC reference - this cancels power-supply drift. If a different ADC reference is used, the ratiometric error introduces an additional 2-3% reading error per 100 mV of supply variation. Severity: recommended.
Do not apply vacuum (negative pressure) to the MPXV5004DP - the datasheet explicitly warns that negative pressure can permanently damage the silicon diaphragm. For applications requiring bidirectional or vacuum measurements, use the MPXV7002 family instead. Also avoid water or liquid ingress into the pneumatic ports; the sensor is intended for dry gas only. Condensation in CPAP or respiratory applications must be prevented by an inline moisture trap. Severity: critical.
