MPXHZ6115AC6T1 Übersicht
A pressure sensor is a transducer that converts an applied gas or fluid pressure into an electrical signal. Absolute pressure sensors reference a sealed vacuum cavity, so the output reflects total pressure relative to that internal vacuum - making them ideal for barometric, altimetric, and sealed-system measurements. The MPXHZ6115AC6T1 belongs to the integrated silicon pressure sensor category, which combines a MEMS piezoresistive bridge with on-chip bipolar op-amp gain and thin-film calibration networks to produce a temperature-compensated, calibrated high-level signal that needs no external compensation circuitry.
Key features include on-chip temperature compensation from -40 °C to +125 °C, maximum overpressure of 400 kPa (58.02 PSI), ratiometric 5 V supply operation, and the media-resistant gel that protects the die from condensation, dust, and corrosive vapors. The integrated op-amp stage delivers a nominal sensitivity of 45.9 mV/kPa while the on-chip thin-film network calibrates the offset and span across temperature.
The internal architecture pairs a diffused piezoresistive strain-gauge bridge with a precision bipolar op-amp chain and laser-trimmed thin-film resistors. This single-chip integration eliminates the discrete instrumentation amplifier that legacy board-mount sensors require, simplifying PCB layout and improving noise immunity by keeping the high-impedance bridge signals on-chip.
Typical applications include barometric pressure measurement for weather stations and altimeters, manifold absolute pressure (MAP) sensing in engine control units, medical respiratory monitoring, HVAC altitude compensation, and sealed-system pressure monitoring where the gel coating protects the die from condensing media.
When designing with this device, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin and keep analog ground return paths short to minimize noise pickup on the high-impedance ratiometric output.

Typische Anwendungen
MPXHZ6115AC6T1 ist geeignet für 6 Anwendungs: Barometric Pressure and Altitude Sensing, Engine Manifold Absolute Pressure (MAP) Sensing, Medical Respiratory and CPAP Pressure Monitoring, HVAC Altitude and Stack Pressure Compensation, Industrial Sealed-System Pressure Monitoring, Drones and UAV Altitude Hold.
Barometric Pressure and Altitude Sensing
The MPXHZ6115AC6T1's 15-115 kPa absolute range covers the full atmospheric pressure span from sea level to high-altitude environments, while its 45.9 mV/kPa sensitivity gives ~22 mV per 100 m of altitude. Placed at the top of the enclosure with the media-resistant gel protecting the die from condensing humidity, it feeds a 5 V ADC or op-amp buffer for weather stations, altimeters, and drone altitude estimators. Unlike digital sensors, its ratiometric 0.2-4.7 V output enables simple connection to any 5 V ADC without I2C pull-ups, but designers must track VCC drift because the output is ratiometric.

Engine Manifold Absolute Pressure (MAP) Sensing
In gasoline and diesel engine control units, the MPXHZ6115AC6T1 measures manifold pressure against the sealed vacuum reference inside the SSOP-8 top-port package, delivering 0.2-4.7 V analog directly to the microcontroller's ADC. The AEC-Q100 qualification and -40 °C to +125 °C range meet under-hood thermal stress, while 45.9 mV/kPa sensitivity provides ~1 kPa resolution when paired with a 10-bit ADC. The media-resistant gel tolerates fuel vapor and humid intake air that would damage standard-gel sensors in turbocharged applications.
Empfohlen
Medical Respiratory and CPAP Pressure Monitoring
The MPXHZ6115AC6T1's media-resistant gel and 400 kPa overpressure tolerance make it suitable for respiratory equipment where condensed breath water vapor contacts the inlet. Mounted at the patient circuit with short tubing to minimize dynamic response lag, it provides real-time airway pressure feedback to CPAP, BiPAP, and ventilator controllers. The 0.2-4.7 V output integrates directly with medical-grade 5 V ADC front-ends, though designers must add bacterial/viral filters between the patient and the sensor to meet hygiene standards per IEC 60601-1.
Empfohlen
HVAC Altitude and Stack Pressure Compensation
Commercial HVAC systems use the MPXHZ6115AC6T1 to compensate burner combustion air/fuel ratios for altitude and to monitor stack draft pressure. Its 15-115 kPa range covers barometric variation from below sea level to high-altitude installations, while the media-resistant gel tolerates flue-gas condensation during cold-start conditions. The ratiometric output pairs with standard 0-5 V HVAC analog input cards without signal conditioning, and the SSOP-8 top-port package mounts directly to intake manifolds for clean airflow sampling.
Empfohlen
Industrial Sealed-System Pressure Monitoring
In sealed hydraulic and pneumatic systems, the MPXHZ6115AC6T1 monitors internal pressure where the absolute reference is essential because the system is sealed from atmosphere. The 0.2-4.7 V output drives 4-20 mA loop converters via simple op-amp scaling for industrial PLC integration, and the AEC-Q100 qualification provides confidence for factory automation environments. Compared to gauge sensors, the absolute reference eliminates vent-tube routing and prevents water ingress at the vent port, simplifying enclosure design for outdoor installations.
Empfohlen
Drones and UAV Altitude Hold
Multirotor drones use the MPXHZ6115AC6T1 as a backup or primary barometric altimeter where its 45.9 mV/kPa sensitivity and 4.75-5.25 V supply integrate directly with 5 V tolerant flight controllers. The 8-SSOP top-port package enables compact board layouts with the inlet facing up through the airframe, and the media-resistant gel handles humid conditions at varying flight profiles. Although digital sensors like BMP280 dominate new designs, the MPXHZ6115AC6T1's analog output and fast warm-up make it valuable in real-time control loops and racing drones requiring minimum latency.

Designhinweise
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VCC pin and add a bulk 1-10 uF tantalum or aluminum capacitor at the supply rail to suppress transients. The MPXHZ6115AC6T1 draws only ~5 mA typical but the on-chip op-amp stage benefits from low-impedance VCC to maintain ratiometric accuracy. Avoid sharing VCC traces with high-current digital loads to prevent ground bounce from coupling into the analog output.
Route the analog VOUT trace as a short, guarded path away from switching nodes, clock lines, and high-current returns. Use a ground pour under and around the sensor to shield against capacitive coupling from neighboring high-impedance nodes. The top-port orientation requires clearance above the package for the pressure tube; do not place components above the inlet that would obstruct airflow.
Buffer the VOUT signal with a low-offset, low-bias-current op-amp (such as MCP6002 or OPA2333) if the ADC input has high impedance or sample-and-hold capacitance that could disturb the sensor output. The sensor's output impedance is typically a few hundred ohms; long PCB traces or low-input-impedance ADCs may load the output and introduce gain error. Add an RC low-pass filter (10 kOhm + 100 nF = ~160 Hz cutoff) to suppress high-frequency noise before ADC sampling.
Self-heating from the on-chip op-amp is minimal (<1 °C rise at 5 V) but the gel coating is sensitive to sustained temperatures above +125 °C. In enclosed housings near heat sources, ensure airflow or thermal isolation to keep the die within the calibrated -40 °C to +125 °C range. Thermal shock from rapid temperature swings can stress the gel bond; allow gradual warm-up in outdoor applications.
Do not apply voltage to VCC outside the 4.75 V to 5.25 V range - this can permanently damage the MEMS bridge and gel coating. Do not block the top port inlet with conformal coating, potting compound, or labels - any obstruction alters the pressure transfer and introduces measurement error. Do not use the NC pins (1, 5-8 in the package variant) as ground returns or signal routing paths; they are not internally bonded for that purpose.
