MPXHZ6115A6T1 개요
An absolute pressure sensor is a transducer that measures pressure relative to a sealed vacuum reference rather than to ambient atmosphere, making it ideal for applications requiring an absolute barometric reference such as altimetry, weather stations, and sealed system monitoring. The MPXHZ6115A6T1 belongs to the MPxx6115A family of integrated pressure sensors, sitting within the broader hierarchy of MEMS sensors -> pressure sensors -> environmental sensors -> semiconductor transducers. Its on-chip signal conditioning eliminates the need for external amplification or calibration circuitry on the PCB.
Key differentiating features include ±1.5% accuracy (specified over the compensated temperature range of 0 °C to 85 °C), temperature compensation from -40 °C to +125 °C, and a maximum overpressure rating of 400 kPa (58.02 PSI). The integrated bipolar op-amp stage delivers a high-level, near-rail-to-rail analog output proportional to applied pressure, simplifying ADC interfacing on the host microcontroller.
The MPXHZ6115A6T1 uses NXP's proprietary micromachined silicon strain-gauge bridge plus bipolar signal chain, with thin-film laser-trimmed resistor networks providing calibration and temperature compensation at the wafer level. This architecture yields repeatable, low-drift output across the specified pressure and temperature windows without requiring user-side software compensation.
Typical applications include engine control manifold absolute pressure (MAP) sensing, barometric altitude measurement, weather stations, HVAC pressure monitoring, and sealed enclosure leak detection. The wide 5 V supply operation and ratiometric analog output allow direct connection to most microcontroller ADC inputs.
When designing with the MPXHZ6115A6T1, provide adequate port venting if measuring ambient pressure and ensure the supply is well-decoupled with a 0.1 µF ceramic capacitor placed close to the supply pin. The ratiometric output means that ADC readings scale with supply voltage, so a stable, low-noise 5 V rail is essential for accurate pressure conversion.

일반적인 애플리케이션
MPXHZ6115A6T1 적합 용도: 6 애플리케이션s: Engine Manifold Absolute Pressure (MAP) Sensing, Barometric Altimeter for Drones and Portable Devices, Weather Station Barometric Pressure Measurement, HVAC System Pressure Monitoring, Sealed Enclosure Leak Detection, Medical Respiratory and CPAP Pressure Monitoring.
Engine Manifold Absolute Pressure (MAP) Sensing
The MPXHZ6115A6T1's 15-115 kPa absolute pressure range covers naturally-aspirated engine manifold pressures through moderate turbo boost, making it ideal for fuel-injection ECU MAP sensing. The on-chip bipolar op-amp signal chain delivers a 0.2-4.7 V analog output directly proportional to manifold pressure, while the -40 °C to +125 °C operating range maintains ±1.5% accuracy under the harsh thermal swings of an underhood environment. Placed on the ECU manifold reference branch with a 0.1 µF supply decoupling capacitor, the sensor feeds the MCU's 5 V ADC without external amplification. Unlike digital MEMS parts requiring I2C/SPI driver code, this analog part reduces firmware complexity and ECU boot time.

Barometric Altimeter for Drones and Portable Devices
The MPXHZ6115A6T1's 15 kPa lower measurement limit resolves altitudes up to roughly 13,500 m above sea level, while its ratiometric 0.2-4.7 V analog output simplifies integration with 5 V portable MCU ADCs. The 8-SOIC surface-mount package fits small form-factor drone flight controllers and handheld GPS units where board space is critical. With ±1.5% accuracy and factory calibration, the sensor provides repeatable altitude data for drone altitude-hold and dead-reckoning applications without user-side software compensation. Pair it with a temperature sensor for higher-altitude flights where temperature-induced drift matters.

Weather Station Barometric Pressure Measurement
The MPXHZ6115A6T1's 15-115 kPa absolute range covers the full atmospheric pressure variation seen in terrestrial weather stations, from deep low-pressure storm systems to high-pressure fair-weather ridges. The on-chip temperature compensation from -40 °C to +125 °C maintains accuracy across outdoor thermal cycling, while the media-resistant PPS package survives humidity exposure common in rooftop weather stations. Its 0.2-4.7 V analog output feeds directly into the weather station's MCU ADC without external amplification. Compared to digital barometric sensors like the BMP280, this part requires no I2C driver code, simplifying weather station firmware.

HVAC System Pressure Monitoring
The MPXHZ6115A6T1 measures duct static pressure and filter differential pressure in HVAC systems, where its 15-115 kPa range captures both sub-atmospheric return-side suction and slight overpressure on the supply side. Its 5 V analog output interfaces directly to building automation controller ADCs, while the -40 °C to +125 °C compensation range handles unconditioned mechanical-room temperature swings. The integrated signal conditioning eliminates the external instrumentation amplifier typically required for bare MEMS pressure die, reducing BOM and assembly cost. Placed in the duct with a Pitot tube pickup, the sensor provides real-time airflow diagnostic data for VAV (variable air volume) controllers.
추천
Sealed Enclosure Leak Detection
The MPXHZ6115A6T1 monitors absolute pressure inside sealed enclosures such as waterproof electronics housings, IP-rated junction boxes, and hermetically sealed sensor pods. Its 15 kPa minimum sensing limit detects vacuum conditions indicating active leak-down, while the 115 kPa upper limit covers internal pressurization tests. The 8-SOIC surface-mount package fits on small PCBs inside the enclosure, and the media-resistant PPS package survives incidental condensation. A microcontroller compares baseline pressure against real-time readings to flag leaks during factory test or in-field diagnostics.

Medical Respiratory and CPAP Pressure Monitoring
The MPXHZ6115A6T1's 15-115 kPa range and ±1.5% accuracy are sufficient for low-acuity respiratory pressure monitoring in CPAP machines, ventilator circuit verification, and spirometer calibration fixtures. Its on-chip calibration eliminates the drift issues seen in discrete pressure transducers, simplifying FDA documentation for medical device designs. The 5 V ratiometric output drives a 5 V medical-grade ADC directly, while the 8-SOIC footprint simplifies board layout in compact handheld devices. Note: for life-support ventilators, verify the specific accuracy class required by IEC 60601 and confirm against NXP's medical-grade portfolio.

설계 노트
The MPXHZ6115A6T1 output is ratiometric to the supply voltage, meaning the same 0.2 V to 4.7 V span scales linearly with Vcc. Place a 0.1 µF ceramic decoupling capacitor as close as physically possible to the Vcc pin (pin 1) to suppress supply noise; add a 10 µF bulk capacitor if the supply traces are longer than 25 mm. According to NXP, supply noise above 50 mVpk will translate directly into ADC pressure errors, so a low-noise LDO (e.g., 50 µVrms or better) is recommended for high-accuracy applications.
The 8-SOIC footprint matches JEDEC SO-8 land pattern, but reserve keep-out zones around the sensor port side (opposite the pin side) to prevent airflow obstruction. If using the no-port PPS variant, mount the sensor with the port-facing surface in direct contact with the measured gas stream or sealed cavity. For axial-port variants (MPXA6115A6T1, MPXAZ6115A6T1), provide at least 5 mm of clearance behind the package to accommodate the port tube and O-ring seal.
Route the analog Vout trace away from switching converter nodes and digital clock lines; the high-impedance sensor output is susceptible to capacitive coupling noise. Add a small RC filter (e.g., 1 kΩ + 100 nF) at the ADC input to limit input bandwidth to about 1.6 kHz if the application does not require fast pressure updates. Avoid ground loops by using a single-point star ground at the sensor GND pin rather than daisy-chaining through multiple vias.
Do not apply pressures above the 400 kPa maximum overpressure rating; even brief transients can permanently damage the MEMS diaphragm. Do not expose the standard PPS package to condensing humidity or liquid media without verifying media compatibility with NXP application note AN1984. Do not assume the output is accurate below 15 kPa or above 115 kPa - the output will saturate near the supply rails and the linearity guarantee does not extend beyond the specified range.
