MPXHZ6115AC6U Overview
A pressure sensor is a transducer that converts an applied gas or fluid pressure into a proportional electrical signal. Absolute-pressure sensors reference an internal sealed vacuum cavity, so the output reflects total pressure relative to perfect vacuum (as opposed to gauge or differential sensors, which reference ambient atmospheric pressure). The MPXHZ6115AC6U integrates bipolar op-amp signal conditioning and a thin-film resistor network on the same silicon die, eliminating the need for external amplification and compensation circuitry at the board level.
Key features include a typical sensitivity of 45.9 mV/kPa, accuracy of ±1.5 % over the compensated temperature range, an operating supply of 4.75 V to 5.25 V, and a media-resistant PPS (polyphenylene sulfide) surface-mount package rated for high-temperature environments. The integrated temperature-compensation network flattens the output across -40 °C to +125 °C, so downstream firmware does not need to apply lookup-based linearization for typical barometric and manifold-absolute-pressure (MAP) readings.
Architecturally, the device uses a piezoresistive MEMS strain-gauge bridge that is laser-trimmed and temperature-compensated at wafer level. The on-chip bipolar op-amp provides a low-impedance ratiometric output proportional to VCC, simplifying ADC sampling in microcontroller-based designs. Media-resistant gel covers the diaphragm, allowing use with non-corrosive air and dry gases.
Typical applications include automotive manifold absolute pressure (MAP) sensing, barometric altimeters and weather stations, industrial pressure instrumentation, HVAC duct-pressure monitoring, and medical respiratory equipment. The 8-SOIC top-port package simplifies board mounting and tube attachment in space-constrained designs.
When designing with this part, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin, and use a stable low-noise 5 V regulator to preserve ratiometric accuracy. Avoid exposing the port to condensing moisture or aggressive chemicals that the PPS-gel media barrier cannot tolerate.

Typical Applications
MPXHZ6115AC6U is suitable for 6 applications: Automotive Manifold Absolute Pressure (MAP) Sensing, Barometric Pressure & Weather Station Sensing, Industrial Low-Pressure Gas Monitoring, HVAC Duct Static-Pressure Sensing, Medical Respiratory & CPAP Equipment, Drone Altitude & Barometric Hold Sensing.
Automotive Manifold Absolute Pressure (MAP) Sensing
The MPXHZ6115AC6U is the industry-standard MAP sensor for port-fuel-injected engines, where it measures intake-manifold absolute pressure for ECU air-mass calculation. The 15-115 kPa range covers naturally aspirated (typically 20-100 kPa) and forced-induction (up to 115 kPa near atmospheric manifold) operating points. The 0.2-4.7 V ratiometric output interfaces directly to 5 V ECU ADC channels without additional signal conditioning, while on-chip temperature compensation from 0 to +85 °C eliminates firmware lookup tables in the under-hood thermal band.
Recommended
Barometric Pressure & Weather Station Sensing
For weather stations and barometric altimeters, the MPXHZ6115AC6U delivers ±1.5 % accuracy across the 15-115 kPa range that encompasses sea-level (101.325 kPa) and altitude variations. The 45.9 mV/kPa sensitivity provides approximately 46 counts/kPa with a 10-bit 5 V ADC, giving ample resolution for storm-front detection. The media-resistant PPS gel port tolerates ambient humidity in outdoor enclosures, and the -40 to +125 °C operating range covers seasonal extremes in temperate climates.
Recommended
Industrial Low-Pressure Gas Monitoring
The MPXHZ6115AC6U suits industrial dry-gas pressure monitoring in compressed-air lines, vacuum-pump diagnostics, and HVAC duct-pressure sensing. Its absolute-pressure reference simplifies instrument calibration (no need for atmospheric venting). The 4.75-5.25 V supply accepts industrial 5 V rails, while the 8-SOIC top-port package enables tube fitting directly to the sensor port for clean plumbing. The media-resistant PPS gel survives exposure to non-corrosive process gases including dry air, nitrogen, and argon.
Recommended
HVAC Duct Static-Pressure Sensing
In HVAC building-automation systems, the MPXHZ6115AC6U monitors duct static pressure to verify filter loading, fan performance, and airflow balancing. The 15-115 kPa range comfortably covers typical duct static pressures (0-2.5 kPa) at one-tenth full-scale, providing high resolution for filter-clog detection. Its 8-SOIC top-port package simplifies mounting on controller boards where a tube routes duct pressure to the sensor. On-chip temperature compensation maintains accuracy across rooftop unit thermal cycles.
Recommended
Medical Respiratory & CPAP Equipment
Medical CPAP machines, ventilators, and spirometers use the MPXHZ6115AC6U to monitor patient-circuit pressure in the 0-115 kPa range. Its low output noise and on-chip calibration support the precision required for breath-pressure waveform analysis. The 5 V ratiometric output interfaces directly to medical-grade ADC front-ends, while the -40 to +125 °C operating range accommodates sterilization environments. Media-resistant gel protects against humidity in patient breath circuits.
Recommended
Drone Altitude & Barometric Hold Sensing
Drones and UAVs use the MPXHZ6115AC6U as a barometric altimeter for height-above-ground hold and altitude telemetry. Its 5 V supply matches typical drone battery-regulation rails, and its small 8-SOIC footprint fits within size-constrained flight-controller boards. At 45.9 mV/kPa, the sensor resolves altitude changes of about 22 cm per ADC LSB (10-bit, 5 V reference), sufficient for stable altitude-hold loops. The -40 to +85 °C range covers commercial-drone operating conditions.

Design Notes
Decouple VCC (pin 1) with a 100 nF ceramic capacitor placed within 5 mm of the IC. Use a low-noise 5 V regulator (such as a TPS7A47xx LDO or LM7805) to preserve the ratiometric accuracy of the analog output. Any supply ripple appears directly on VOUT because the device is ratiometric; ripple above 50 mV pk-pk will degrade effective ADC resolution.
Place the 8-SOIC package away from board-edge heat sources and route the tube port upward away from the PCB to prevent condensation migration into the gel barrier. Maintain at least 3 mm clearance around the top port for tube-fitting clearance. Connect GND (pin 2) to a low-impedance ground plane for stable readings; avoid routing high-current traces beneath the sensor body.
Do not apply more than 400 kPa peak pressure to the port - the media-resistant gel can rupture above its rated overpressure. Avoid exposing the port to condensing moisture or corrosive gases (chlorine, strong acids) that degrade the PPS gel barrier. Always average at least 4 ADC samples to suppress single-sample noise when sampling below 1 kHz.
The output is ratiometric to VCC, so the ADC reference must be the same 5 V rail (or use the on-chip VCC as the ADC reference pin) to cancel supply drift. For long cable runs between sensor and ADC, add an op-amp buffer at the sensor end to prevent capacitive loading distorting the output. Use shielded cable if routing near motor inverters or switching supplies.
