MPXHZ6116A6U - 20-115 kPa Absolute Pressure Sensor | NXP
MPN： MPXHZ6116A6U ✓ 啟用中MPXHZ6116A6U 概覽
A pressure sensor is a transducer that converts an applied gas or fluid pressure into a proportional electrical signal. Absolute pressure sensors, like the MPXHZ6116A6U, reference a sealed internal vacuum cavity so the output represents pressure relative to perfect vacuum rather than ambient atmosphere. This makes them well suited for sealed-system monitoring such as engine manifold absolute pressure (MAP), barometric correction, weather stations, sealed enclosures, and altitude estimation, where the absolute reference is required for accurate measurement. Within the broader sensor taxonomy, the device belongs to: pressure sensor -> piezoresistive/MEMS pressure transducer -> absolute pressure transducer -> environmental sensor IC.
Key specifications include a 5.0 V typical supply (4.75 V to 5.25 V), ratiometric output of approximately 5% to 90% of VCC, ±1.5% (max) accuracy over 0 °C to 85 °C with temperature compensation from -40 °C to +125 °C, 1 ms settling time, and 6 mA typical supply current. The integrated bipolar op-amp stage and on-chip thin-film calibration network provide a calibrated, amplified signal without the need for external trim or compensation components.
The MPXHZ6116A6U uses a piezoresistive MEMS strain gauge diffused into a silicon diaphragm; deflection under pressure changes the bridge resistance, which the on-chip amplifier then linearizes and temperature-compensates. The result is a near-linear voltage output that can be fed directly to a microcontroller ADC. The HZ series suffix denotes the highest-ruggedized media-resistant port geometry, allowing exposure to harsh environments.
Typical applications include automotive manifold absolute pressure (MAP) sensing, HVAC pressure monitoring, weather stations, altitude measurement, industrial process control, and sealed-enclosure leak detection. The wide 5 V supply tolerance and ratiometric output simplify design with 5 V microcontrollers and ADC front ends.
When designing with this part, note that the output is ratiometric to the supply voltage, so a clean, stable 5 V rail is essential for accurate readings. Decouple VCC with 0.1 µF ceramic + 1 nF noise-bypass capacitors placed close to the supply pin to prevent ADC conversion noise. Do not apply pressures beyond 400 kPa to avoid permanent damage to the silicon die.

典型應用
MPXHZ6116A6U 適用於 6 應用s: Automotive Manifold Absolute Pressure (MAP) Sensing, Barometric Altitude Measurement, HVAC Pressure Monitoring, Weather Station Barometer, Sealed Enclosure Leak Detection, Industrial Process Control Pressure Monitoring.
Automotive Manifold Absolute Pressure (MAP) Sensing
The MPXHZ6116A6U is a direct fit for MAP sensor signal conditioning in gasoline engine control units. The 20-115 kPa range exactly covers atmospheric to full-boost pressures encountered in naturally aspirated and turbocharged engines, while the ratiometric 0.399-4.645 V output feeds directly into an ECU ADC without external amplification. The HZ port style stops resist fuel vapor, oil and dust, lowering the maintenance burden in under-hood environments. With 1 ms settling time the device easily tracks cylinder-to-cylinder pressure events at engine speeds up to 6000 RPM, supporting accurate fuel mapping and ignition timing. Decouple VCC with 0.1 µF ceramic + 1 nF caps placed within 5 mm of the supply pin to suppress ignition-switching noise.

Barometric Altitude Measurement
The MPXHZ6116A6U's 20-115 kPa range covers sea level (~101 kPa) down to roughly 9.5 km altitude (~30 kPa), making it well suited for hobbyist drones, handheld weather stations, and balloon-borne instrumentation. Output is ratiometric, so the same 5 V rail powers both the sensor and the MCU ADC reference for highest accuracy. With ±1.5% accuracy and a temperature-compensated output, the device yields altitude resolutions of approximately ±1-2 m after ISA-model conversion when the ADC oversamples 16-64 times. Use a low-noise LDO such as NXP's TLV1117 to power the sensor, and place inlet port away from direct airflow to avoid wind-induced pressure spikes.
推薦
HVAC Pressure Monitoring
Commercial HVAC systems monitor refrigerant and air-side duct pressures for compressor protection and energy optimization. The MPXHZ6116A6U's 20-115 kPa range matches the air-side duct pressures of most residential and light-commercial systems, while its media-resistant port handles humid indoor air and dust. The integrated amplifier/calibration removes the need for external op-amp circuits, reducing BOM cost on the controller PCB. With 6 mA typical supply current, the device is well suited for line-powered, always-on HVAC controllers. Add a 0.1 µF ceramic bypass capacitor on VCC and a 10 kΩ + 100 nF RC low-pass filter on VOUT for EMC compliance in noisy fan/compressor environments.
推薦
Weather Station Barometer
The MPXHZ6116A6U serves as the barometric pressure element in consumer weather stations and personal weather displays. Its 20-115 kPa range fully spans the meteorologically relevant 870-1084 hPa range at sea level plus altitude variations, while the analog output simplifies interface to any 5 V microcontroller ADC. The ±1.5% accuracy translates to ±1.5 hPa barometric resolution, sufficient for storm-detection tracking of rapid pressure drops (>3 hPa/3 h). The HZ media-resistant port stops moisture ingress in outdoor enclosures. With on-chip temperature compensation over 0-85 °C, the device eliminates the need for a separate temperature-compensation lookup table, freeing MCU cycles for wind, rain and humidity sensor processing.
推薦
Sealed Enclosure Leak Detection
Sealed enclosures for electronics (underwater housings, vacuum chambers, hermetic instrument cases) require absolute-pressure monitoring to detect seal degradation. The MPXHZ6116A6U's absolute pressure reference (sealed vacuum cavity) distinguishes internal pressure changes from atmospheric drift, which is critical for detecting slow leaks below 1 kPa/yr. The 20-115 kPa range covers both vacuum and pressurized cases. Use two MPXHZ6116A6U devices - one inside the enclosure, one outside - to compute differential drift as a leak indicator. With 1 ms settling time the device can be polled at sub-second intervals with sleep-mode current of typically under 1 µA when VCC is gated.
推薦
Industrial Process Control Pressure Monitoring
Factory automation and process control often monitor low-pressure pneumatic lines and gas flows in the 0-100 kPa range. The MPXHZ6116A6U's 20-115 kPa range, ±1.5% accuracy, and ratiometric 5 V output make it a drop-in pressure transducer for pneumatic control valves, gas analyzers, and cleanroom pressure-differential monitoring. The integrated temperature compensation and amplifier stage eliminate external op-amps, reducing BOM and PCB area in space-constrained control modules. With 1 ms settling time the sensor tracks fast pressure transients in valve actuation. Use a TVS diode such as NXP's PESD5V0L1BA on VCC for industrial surge protection, and place the sensor port upstream of any filter to avoid pressure loss across filter media.

設計說明
The MPXHZ6116A6U requires a clean, low-noise 5 V supply because the analog output is ratiometric to VCC. Any ripple on VCC couples directly into the pressure reading - a 50 mV ripple on VCC translates to ~12 mV error on VOUT (~5% of full scale). Use an NCP1117 or TLV1117 5 V LDO with at least 10 µF output capacitance, and add a 0.1 µF ceramic + 1 nF noise-bypass capacitor pair placed within 5 mm of the VCC pin. Avoid sharing VCC with switching DC/DC converters or relay coils without filtering.
Place the MPXHZ6116A6U at the edge of the PCB with the HZ port facing the enclosure boundary to minimize pressure-sampling path length. Route VOUT away from noisy digital traces and switching-node signals; if the trace exceeds a few cm, add a 10 kΩ + 100 nF RC low-pass filter at the MCU ADC input. Keep the port geometry clear of obstructions and ensure the silicone gel media protection is intact before reflow. Pin 1 (VCC) and pin 2 (GND) should be decoupled with ceramic capacitors placed as close as possible to the package body, with a continuous ground pour beneath the exposed pad region.
Do not apply pressures beyond the maximum overload rating (consult NXP datasheet for exact figure - [DATA_NEEDED: maximum overload pressure]) as this permanently damages the silicon die. Do not assume the output is independent of VCC - the device is ratiometric, so any drift or noise on the 5 V rail degrades accuracy. The HZ port contains a silicone gel that should not be touched, contaminated, or exposed to solvents - use protective tape during PCB assembly and remove it only after final enclosure integration. Calibration coefficients are pre-programmed per device; do not attempt field recalibration as this voids warranty.
