MPXH6115AC6U 概述
An absolute pressure sensor is a transducer that outputs a voltage proportional to pressure measured relative to a sealed internal vacuum cavity rather than to local ambient atmosphere, making it immune to weather and altitude-induced reference drift; this places the device in the broader transducer > barometric sensor > sensor hierarchy used in automotive, medical, and industrial embedded systems.
Key features include on-chip bipolar op-amp signal conditioning, thin-film resistor network for temperature compensation across 0 C to +85 C, a typical sensitivity of 45.9 mV/kPa, and 5 V supply operation with 4.75 V to 5.25 V tolerance; the operation runs from -40 C to +125 C and the SOIC-8 package allows standard surface-mount assembly with the port integrated into the top of the body, eliminating the need for external tubing adapters.
The MPXH6115AC6U uses piezoresistive MEMS silicon micromachining combined with bipolar op-amp circuitry to provide a high-output, temperature-compensated signal without requiring external amplification; the integrated bandgap reference and laser-trimmed resistors eliminate the need for software calibration in many applications, which simplifies firmware development.
Typical applications include automotive engine control units (MAP sensing), barometric altitude measurement for GPS-augmented navigation, weather stations, altimeters, and HVAC pressure monitoring; the wide operating temperature makes it particularly suited to under-hood automotive environments.
Designers should ensure the supply is regulated to 5 V +/- 5% and that an RC low-pass filter is added on the output if the ADC sampling rate introduces aliasing of high-frequency pressure transients. The tube port orientation must be sealed against moisture and debris in field installations.

典型应用
MPXH6115AC6U 适用于 7 应用s: Automotive Manifold Absolute Pressure (MAP) Sensing, Barometric Altimeter for GPS Navigation, Weather Station Pressure Monitoring, Medical Respiratory / CPAP Pressure Monitoring, HVAC Differential Pressure Monitoring, Industrial Process Control Pressure Sensing, Drone / UAV Altitude Hold.
Automotive Manifold Absolute Pressure (MAP) Sensing
The MPXH6115AC6U's 15 kPa to 115 kPa absolute range directly covers the barometric and manifold vacuum pressures seen in gasoline and diesel engine intake systems. With 45.9 mV/kPa typical sensitivity and ratiometric 0.2 V to 4.7 V output at 5 V supply, it drives automotive ECU ADCs without external amplification, while the -40 C to +125 C operating range survives under-hood thermal stress. The on-chip temperature compensation from 0 C to +85 C eliminates the need for lookup-table correction in the ECU firmware.
推荐
Barometric Altimeter for GPS Navigation
The MPXH6115AC6U's 15 kPa to 115 kPa range covers the full barometric pressure spectrum from sea level to ~12 km altitude, and its 0.2 V to 4.7 V output can be sampled by a 12-bit ADC to resolve 0.025 kPa steps - equivalent to roughly 2 meters altitude. The calibrated, on-chip temperature-compensated output eliminates the need for field recalibration. Combined with GPS data, it enables handheld GPS units, drones, and avionics to compute pressure altitude for enhanced positioning.
推荐
Weather Station Pressure Monitoring
The MPXH6115AC6U's absolute-pressure reference is immune to weather-front-induced ambient drift, making it ideal for fixed weather stations measuring local barometric pressure. The 5 V supply and 0.2 V to 4.7 V output can be read by virtually any MCU ADC, and the -40 C to +125 C operating range survives outdoor deployment. The top-port tube design accepts standard 3.3 mm ID pneumatic tubing for sealed weatherproof installation.
推荐
Medical Respiratory / CPAP Pressure Monitoring
The MPXH6115AC6U's 15 kPa to 115 kPa range covers the pressure domain of medical CPAP and BiPAP machines (typically 4-20 cmH2O). Its calibrated, temperature-compensated output can be sampled by an isolated front-end ADC in IEC 60601-compliant medical devices. The single 5 V supply and small SOIC-8 footprint allow integration into compact handheld or bedside medical pressure monitoring. [DATA_NEEDED: specific medical certifications]
推荐
HVAC Differential Pressure Monitoring
The MPXH6115AC6U is well suited to HVAC duct static pressure measurement where absolute pressures from 15 kPa to 115 kPa are typical. Its top-port tube connection accepts 3.3 mm tubing for inline duct installation, and the ratiometric output simplifies signal conditioning when paired with HVAC controllers operating on the same 5 V rail. The compensated temperature range of 0 C to +85 C covers most indoor and rooftop unit environments.
推荐
Industrial Process Control Pressure Sensing
The MPXH6115AC6U's calibrated output and on-chip signal conditioning simplify PLC and industrial-controller pressure monitoring designs. The 5 V single-supply operation integrates with legacy 5 V analog input modules, and the SOIC-8 top-port package mounts directly to a process tube via standard pneumatic fittings. The -40 C to +125 C operating range and on-chip temperature compensation reduce calibration cycles.
推荐
Drone / UAV Altitude Hold
The MPXH6115AC6U provides absolute altitude reference for drone flight controllers, complementing GPS data with finer-grained altitude resolution near the ground where GPS accuracy degrades. The 45.9 mV/kPa sensitivity and 0.2 V to 4.7 V output are easily sampled by 10- or 12-bit ADCs common in flight controllers, and the small SOIC-8 footprint fits tight airframes. The -40 C to +85 C range suits consumer and prosumer UAVs.

设计说明
The MPXH6115AC6U requires a regulated 5 V supply within +/-5% (4.75 V to 5.25 V). Add a 100 nF decoupling capacitor close to the VCC pin and a 10 uF bulk capacitor at the supply rail. Since the output is ratiometric, any supply noise will couple directly to the output voltage. Use an LDO or low-noise DC-DC supply for measurement applications where noise must remain below 1 LSB of the downstream ADC.
Add an RC low-pass filter on the output (typical: 1 kohm + 100 nF, fc ~= 1.6 kHz) to suppress high-frequency pressure transients and noise above the ADC Nyquist frequency. The MPXH6115AC6U output impedance is typically ~1 kohm per the datasheet, so the filter will introduce minimal offset error. For precision barometric measurements, use an ADC with at least 12-bit resolution and ratiometric sampling tied to the same VCC reference.
The 8-SOIC top-port package must be mounted at the edge of the PCB with the tube port exposed to atmosphere - do not route signal traces beneath the package or place components within 2 mm of the port opening. The top port accepts 3.3 mm ID tubing; ensure the tubing seal is airtight with cable ties or hose clamps to prevent false readings from leaks. For automotive under-hood mounting, isolate the sensor from vibration using a rubber isolator and short flexible tubing.
Estimated: at 25 C ambient with 5 V supply and no load, the sensor draws <10 mA and dissipates approximately 50 mW; thermal rise is negligible. The 0 C to +85 C compensated range ensures calibrated accuracy, but operating at -40 C or +125 C will introduce ~1-2% additional error per the datasheet accuracy derating curve. For outdoor weather-station deployments, mount the sensor inside an enclosure with thermal isolation from direct sunlight.
Do not reverse VCC and GND - the MPXH6115AC6U has no reverse-polarity protection and will be damaged. Do not apply pressure outside the 0 kPa to 200 kPa absolute overrange limit - the sensor can be permanently damaged by overpressure. Do not block the tube with adhesives or conformal coating - leave the tube port vented to the measurement environment. Finally, account for the ratiometric output: Vout scales with VCC, so a 4.85 V supply produces 2.7% lower output than 5 V at the same pressure.
