MPXV6115V6T1 Overview
What is a board-mount pressure sensor? A board-mount pressure sensor is a MEMS-based transducer that converts applied pneumatic pressure into a calibrated analog voltage and is soldered directly onto a PCB, eliminating hose-to-PCB connectors. Within the broader sensor hierarchy, it belongs to piezoresistive MEMS sensors -> pressure sensors -> transducers -> sensors -> electronic components. The MPXV6115V6T1 is part of NXP's integrated MPXx family that adds ASIC signal conditioning directly on the silicon die, simplifying downstream analog front-end design.
Key features include a calibrated full-scale output span of approximately 4.4 V across the -115 kPa to 0 kPa vacuum range, an on-chip temperature compensation network that flattens the output across 0 C to +85 C, and a robust gull-wing SMD leadframe that survives standard reflow profiles. The single-rail 5 V supply and ratiometric analog output simplify interfacing to microcontrollers with built-in ADCs, while the integrated op-amp eliminates the need for an external instrumentation amplifier.
Architecturally, the MPXV6115V6T1 uses a piezoresistive Wheatstone bridge diffused into a micromachined silicon diaphragm; the bridge output is conditioned by an on-die bipolar op-amp stage and a thin-film resistor network that performs offset and span calibration plus first-order temperature compensation. This integration trades the noise and drift of a discrete instrumentation chain for the convenience of a calibrated, ready-to-use analog module.
Typical applications include HVAC vacuum monitoring, medical respiratory equipment, barometric altitude correction, and industrial process control where a compact, surface-mount vacuum transducer is required. The wide 0.2 V to 4.6 V swing is particularly well-suited to 5 V ADC full-scale ranges without external signal conditioning.
When designing with this part, place 100 nF decoupling close to the supply pin and route the analog output away from switching nodes. The sensor is ratiometric to VDD, so any ripple on the 5 V rail appears directly on the output; an LDO upstream improves absolute accuracy.

Typical Applications
MPXV6115V6T1 is suitable for 6 applications: HVAC Vacuum Monitoring, Medical Respiratory Equipment, Engine Manifold Vacuum Sensing, Barometric Altitude Correction, Industrial Process Control, Appliance Vacuum / Flow Sensing.
HVAC Vacuum Monitoring
The MPXV6115V6T1's 0 to -115 kPa range directly matches the negative-pressure swings seen across chiller suction lines and refrigerant vacuum service ports, where pressures of -60 to -100 kPa indicate proper dehydration before charging. Its 0.2 V to 4.6 V ratiometric output feeds any 5 V ADC on the HVAC controller without an instrumentation amplifier, while the integrated temperature compensation keeps the reading stable across compressor-cabinet ambient swings of 0 C to +85 C. A 100 nF decoupling capacitor placed within 5 mm of pin 3 (VDD) suppresses compressor switching noise that would otherwise alias into the analog output.
Recommended
Medical Respiratory Equipment
In CPAP, BiPAP, and portable suction devices, the MPXV6115V6T1's -115 kPa full-scale range covers every realistic negative-pressure transient from -20 kPa (exhalation assist) to -90 kPa (deep suction). The on-chip bipolar op-amp stage delivers a low-noise analog output that an isolation-amplifier front end can scale directly to the medical-grade ADC, eliminating a discrete instrumentation chain that would otherwise drift with temperature. Because the device is ratiometric to a single 5 V rail, isolation is straightforward with a DC-DC plus an isolation amplifier, simplifying IEC 60601-1 patient-leakage budgeting.
Recommended
Engine Manifold Vacuum Sensing
The MPXV6115V6T1 measures intake-manifold depression across idle (-60 to -85 kPa) through wide-open throttle (near 0 kPa), enabling closed-loop fuel-map trim and EGR validation on small engines and legacy ECU retrofits. Its 4.4 V output span on a 5 V ADC maximizes usable resolution in the operating region, and the SOP-8 gull-wing package survives under-hood thermal and vibration stress typical of automotive auxiliary electronics. A small RC low-pass on the output (1 kohm + 100 nF) filters combustion-cycle pressure pulsations before they reach the ADC sample window.
Recommended
Barometric Altitude Correction
For portable weather stations and outdoor drones that need altitude correction from a single 5 V analog rail, the MPXV6115V6T1's vacuum-mode transfer function reads the deviation from local barometric pressure directly when referenced to a sealed ambient port. The integrated temperature compensation keeps the reading stable as the unit moves between sun and shade, while the small SOP-8 footprint fits a 10 mm x 12 mm PCB island. Pair the output with a low-drift LDO on the 5 V rail to keep absolute error below ±1.5% across the full operating temperature window.
Recommended
Industrial Process Control
In vacuum-conveying systems for pellet and powder handling, the MPXV6115V6T1 monitors line depression between -40 and -90 kPa to detect blockages and verify pickup. The SOP-8 surface-mount package allows direct soldering onto the conveyor-control PCB without hose-to-board bulkhead connectors, eliminating a leak path common in pneumatic lines. The on-chip op-amp and resistor network deliver a calibrated 0.2 V to 4.6 V output that the conveyor PLC reads through its analog input module with no external signal conditioning.
Recommended
Appliance Vacuum / Flow Sensing
Coffee machines, vacuum sealers, and robotic pool cleaners use the MPXV6115V6T1 to verify pump suction between -30 and -100 kPa, ensuring consistent extraction pressure and detecting clogged filters. The 5 V single-rail operation matches the existing appliance power supply, while the integrated signal conditioning removes the need for a precision analog front end in a cost-sensitive consumer BOM. The SOP-8 footprint fits inside the appliance chassis next to the pump without a separate sensor housing, reducing assembly cost.

Key Differentiators
- Calibrated -115 kPa vacuum range with on-chip signal conditioning (vs MPX4250GP)
- 5 V single-rail ratiometric analog output (vs Bosch BMP280)
- SOP-8 gull-wing SMD package (vs MPX6115 in through-hole package)
- Integrated temperature compensation on the silicon die (vs Discrete pressure bridge + external instrumentation amplifier)
Design Notes
The MPXV6115V6T1 output is ratiometric to VDD, so any ripple or noise on the 5 V rail appears directly on the pressure reading. Estimated: at 1% VDD ripple the output error is 1% of full scale (about 44 mV), which exceeds the sensor's specified ±1.5% accuracy band. Place a 100 nF decoupling capacitor within 5 mm of pin 3 (VDD) and feed the sensor from a low-noise LDO rather than a switching converter rail.
Route the analog output (pin 1) as a short, guarded trace away from switching nodes such as PWM pumps, relay coils, and IGBT drivers. A 1 kohm series resistor plus 100 nF shunt capacitor at the ADC input forms a low-pass filter that rejects conducted pump noise above the ADC's Nyquist frequency without loading the sensor output (the on-chip op-amp easily drives 5 kohm). Keep the ground return for the sensor separate from high-current grounds to avoid ground bounce.
For best absolute accuracy, run the host ADC from the same 5 V rail as the sensor and use a differential or ratiometric ADC reference tied to VDD; this cancels any residual supply drift. If the system MCU runs from 3.3 V, add a resistive divider on the sensor output or buffer with a rail-to-rail op-amp to keep the reading within the ADC input range. Sample the ADC at >1 kHz and average 16 samples to remove combustion-cycle or pump pulsation noise.
Do not connect pins 4 to 8 to anything - they are factory test pins and may inject noise or load the internal nodes if driven externally. Avoid conformal coatings that seal the SOP-8 top port (where present on variant packages); the standard MPXV6115V6T1 is a no-port device intended for external hose connection, so any sealed enclosure will trap pressure and distort readings.
Compliance Information
RoHS and REACH compliant per NXP product page; lead-free gull-wing terminations support 245 C reflow. AEC-Q100 is not qualified - use the MPX6115 family Q-graded variants for automotive applications. Halogen-free status should be verified against the latest NXP material declaration before design freeze.
