MPXV6115VC6U Übersicht
A pressure sensor transducer is a semiconductor device that converts an applied pressure - mechanical force per unit area - into a proportional electrical signal, typically via a piezoresistive strain-gauge network diffused into a silicon diaphragm. The MPXV6115VC6U belongs to the broader piezoresistive transducer family (piezoresistive sensor -> pressure sensor -> MEMS sensor -> transducer) and is widely used in system-level designs where a clean, conditioned analog rail directly interfaces with a microcontroller ADC.
Key features include a measurement range of -16.68 PSI to 0 PSI (-115 kPa to 0 kPa), a ratiometric 0.2 V to 4.6 V output, a typical accuracy of 1.5% across the compensated temperature range, and a 5 V single-supply operation. The 3.17 mm (0.13 in) vertical top port accepts a vacuum tube directly, eliminating hose-to-board adapters in many respiratory and analytical instrument designs.
The MPXV6115VC6U uses a piezoresistive Wheatstone-bridge strain-gauge network diffused into a chemically-etched silicon diaphragm; deflection under vacuum unbalances the bridge, and the on-chip bipolar op-amp network amplifies and temperature-trims the differential signal to a single-ended 0.2 V to 4.6 V output. The 8-SMD gull-wing package is a surface-mount variant of the legacy SOP-8 with extended leads for improved solder-joint reliability, and the device is qualified for -40 C to +125 C operation.
Typical applications include medical respiratory and CPAP instruments, HVAC vacuum monitoring, industrial vacuum gauges, and analytical instruments such as COVID-19 diagnostic consumables. The vacuum-only range and ratiometric output make the part particularly well suited to single-supply battery-powered systems that need a calibrated, temperature-compensated vacuum reading without external signal conditioning.
When designing with this device, route the analog output trace away from switching converters and add an RC filter at the ADC input; the small output swing (0.2 V to 4.6 V) sits well within the common-mode range of most 5 V SAR ADCs but is sensitive to ground noise. The top port must remain unobstructed for accurate readings.

Typische Anwendungen
MPXV6115VC6U ist geeignet für 6 Anwendungs: Medical Respiratory / CPAP Instruments, HVAC Vacuum Monitoring, COVID-19 Diagnostic Consumables, Industrial Vacuum Gauges, Analytical Instrumentation, Portable Battery-Operated Vacuum Tools.
Medical Respiratory / CPAP Instruments
The MPXV6115VC6U measures patient-circuit vacuum in CPAP and BiPAP machines where inspiratory pressure must be monitored below atmospheric. The -115 kPa to 0 kPa range covers the full vacuum spectrum in airway pressure sensing, and the ratiometric 0.2 V to 4.6 V output at 5 V supply interfaces directly with the on-board SAR ADC without external signal conditioning. The on-chip bipolar op-amp network and thin-film calibration deliver a calibrated 1.5% accuracy across 0 C to 85 C, eliminating per-unit trimming in production. The 8-SMD top-port package allows the pressure tube to mount directly to the sensor, simplifying the pneumatic path.

HVAC Vacuum Monitoring
In HVAC service equipment and refrigeration vacuum gauges, the MPXV6115VC6U provides a continuous analog indication of system vacuum during pump-down and evacuation. The -115 kPa to 0 kPa range matches the typical 500 micron (67 Pa) to atmospheric vacuum pull-down range, and the 0.2 V to 4.6 V output drives a panel meter or ADC directly. The 5 V ratiometric output is insensitive to supply drift when read with the same ADC reference, and the surface mount 8-SMD package keeps the bill-of-materials cost low in service-tool designs.
Empfohlen
COVID-19 Diagnostic Consumables
The MPXV6115VC6U was specifically adopted by medical-device manufacturers during the COVID-19 response for vacuum-pressure monitoring in diagnostic cartridges and respiratory analyzers. Per the NXP community thread, the part was chosen over the MPXV4115VC6U equivalent due to supply availability and identical specifications. The calibrated, temperature-compensated output removes the need for per-device calibration in single-use consumables, and the small 8-SMD footprint enables compact cartridge designs.
Empfohlen
Industrial Vacuum Gauges
For handheld and benchtop industrial vacuum gauges used in laboratory and process-equipment service, the MPXV6115VC6U provides a low-cost, calibrated analog front-end. The 0.2 V to 4.6 V ratiometric output at 5 V supply can drive a 3.5-digit panel meter directly or feed an MCU ADC for digital readout. The -40 C to +125 C operating range covers harsh factory-floor temperatures, while the 1.5% accuracy is sufficient for service-grade rather than metrology-grade vacuum measurement.
Empfohlen
Analytical Instrumentation
In mass-spectrometer inlet systems, vacuum concentrators, and lyophilizers, the MPXV6115VC6U provides a continuous vacuum feedback signal for process control. The -115 kPa to 0 kPa range is compatible with rough-pump and turbomolecular-pump operation, and the calibrated output interfaces directly with PID controllers without signal-conditioning overhead. The on-chip temperature compensation from 0 C to 85 C maintains accuracy across typical laboratory ambient conditions.
Empfohlen
Portable Battery-Operated Vacuum Tools
Battery-powered vacuum cleaners, robotic pool cleaners, and portable pneumatic tools benefit from the MPXV6115VC6U's low 5 V supply current and ratiometric output. The 8-SMD gull-wing top-port package simplifies the pneumatic interface, while the calibrated accuracy allows the MCU to display vacuum level directly without per-unit calibration. The small footprint keeps the BOM compact for portable-form-factor products.

Wichtigste Unterscheidungsmerkmale
- On-chip temperature compensation and calibration (vs. Discrete strain-gauge + op-amp solution)
- Top-port vertical tube simplifies pneumatic interface (vs. Side-port MPX5100DP family)
- Ratiometric analog output interfaces directly with 5 V SAR ADC (vs. Digital-output Bosch BMP280)
Designhinweise
The MPXV6115VC6U is ratiometric: the 0.2 V to 4.6 V output scales linearly with VCC. Use the same 5 V LDO that powers the MCU ADC to drive the sensor, and use VCC as the ADC reference, to eliminate supply-noise coupling. A low-noise LDO such as TPS7A4533 is recommended; switching converters should be filtered with a ferrite bead and 10 uF ceramic cap to prevent switching ripple from coupling into the analog output.
Route the analog output (VOUT, pin 3) trace away from switching converters, digital buses, and high-current traces. Place a 1 nF ceramic capacitor close to the VOUT pin and a 100 nF capacitor close to VCC to filter high-frequency noise. The top-port tube should mount vertically with adequate clearance above the PCB; do not cover the port with conformal coating or potting compound, which would block pressure transmission.
Do not apply positive pressure above 0 PSI to the MPXV6115VC6U - the part is vacuum-only and may be damaged by overpressure in the positive direction. The exact maximum overpressure rating was not present in the verified data [DATA_NEEDED: maximum overpressure]. Do not confuse this part with the MPX6115DP (positive-gauge 0 to 115 kPa), which has the same package but a different pressure range and pin assignment for the second port.
