MPXHZ6116A6T1 Descripción general
An absolute pressure sensor is a transducer which produces an output voltage referenced to an internal vacuum cavity rather than to ambient atmospheric pressure. Pressure sensors in this category belong to the broader MEMS and sensor hierarchy: pressure transducer -> piezoresistive sensor -> MEMS sensor -> semiconductor sensor -> electronic sensor. Absolute references are critical in applications that must distinguish barometric pressure altitude, sealed-cavity pressure, or any closed-volume measurement where the surrounding atmosphere cannot be used as the reference.
Key features include on-chip temperature compensation over 0 C to 85 C, factory calibration that eliminates the need for external trimming, a 5 V nominal supply with low current draw, and media-resistant port versions for use with non-corrosive gases and lightweight fluids. The piezoresistive sensing element is fabricated using bulk-micromachined silicon and is electrically isolated from the media-side gel coating used to protect the diaphragm from contamination.
The MPXHZ6116A6T1 architecture pairs a Wheatstone-bridge piezoresistive cell with a precision bipolar op-amp and laser-trimmed thin-film resistor network, providing temperature compensation from -40 C to +125 C operating range with calibrated accuracy typically better than 1.5 percent over the compensated range. The high-level 0.399 V to 4.645 V swing interfaces directly to microcontrollers with A/D inputs without additional gain stages, simplifying BOM and PCB layout.
Typical applications include HVAC blower control, weather station barometry, altimeter instrumentation, medical respiratory monitoring, tire-pressure monitoring subsystems, sealed-system leak testing, and industrial process control where absolute pressure measurement is required.
Design tip: place a 100 nF decoupling capacitor close to the VCC pin and route the analog output away from switching regulator and high-current traces to minimize conducted noise coupling into the sensor signal chain. Use the 5 V supply tolerance recommended by NXP to maintain calibrated accuracy.

Barometric Weather Station and Altimeter
The MPXHZ6116A6T1 measures 20 kPa to 115 kPa absolute pressure, which spans from approximately -500 m altitude below sea level to +9,000 m above, making it ideal for portable weather stations and outdoor altimeters. The on-chip bipolar op-amp delivers a high-level 0.399 V to 4.645 V signal that interfaces directly to a 10-bit or 12-bit MCU A/D converter. The media-resistant gel coating protects the die from humidity and dust ingress, which is essential for outdoor weather instrumentation exposed to the elements for years.

Medical Respiratory and CPAP Monitoring
The MPXHZ6116A6T1 absolute-pressure sensing provides accurate 20 kPa to 115 kPa measurement required for CPAP machine airflow feedback and respiratory-pressure monitoring. The factory-calibrated output eliminates the per-unit trim step needed by medical device manufacturers and reduces overall bill-of-materials cost. The SOIC-8 single-axial-port package allows compact PCB layout, and the media-resistant gel protects against condensation in humidified air circuits. According to the datasheet, the 6 mA typical supply current keeps total system power low for battery-backed bedside equipment.

Automotive Tire Pressure Auxiliary Sensing
The MPXHZ6116A6T1 20 kPa to 115 kPa absolute-pressure window covers the standard automotive tire inflation range and the auxiliary barometric reference used by indirect TPMS modules. The -40 C to +125 C operating range meets automotive underhood and wheel-well environmental requirements. The media-resistant gel coating protects against road splash, and the SOIC-8 surface-mount package enables automated pick-and-place assembly for high-volume TPMS module production.

Sealed-Volume Leak Testing and Industrial Process
The MPXHZ6116A6T1 absolute-pressure reference is ideal for sealed-volume leak detection, where a fixed vacuum or fixed charge must be measured against an absolute reference rather than ambient atmosphere. The 0.399 V to 4.645 V ratiometric output tracks the 5 V supply, allowing a single regulator to power both the sensor and the MCU without calibration drift. The 6 mA typical supply draw and small SOIC-8 footprint enable multi-point sensing arrays on a single industrial backplane.
Recomendado
Drone and UAV Altitude Hold Reference
The MPXHZ6116A6T1 absolute barometric sensor provides the altitude-hold reference for small UAVs and drones, where 20 kPa to 115 kPa covers ground level through several kilometers of flight ceiling. The 6 mA supply current and SOIC-8 surface-mount package fit within weight-constrained flight-controller boards. The factory calibration eliminates the per-unit barometric trim step in production, simplifying high-volume drone manufacturing while maintaining altitude-hold accuracy suitable for stabilized flight.
Recomendado
Appliance Water-Level and Pump Pressure Sensing
The MPXHZ6116A6T1 absolute-pressure sensing can be referenced against a vacuum-side head to measure water column height in washing machines, dishwashers, and pump systems. The SOIC-8 single-port package with media-resistant gel tolerates humid sealed-volume conditions for years. The calibrated 0.399 V to 4.645 V output allows direct interface to appliance MCU A/D converters without additional signal conditioning, reducing BOM and assembly cost in high-volume white-goods production.

Notas de diseño
Power the MPXHZ6116A6T1 from a regulated 5 V rail with a 100 nF decoupling capacitor placed within 5 mm of the VCC pin. Because the output is ratiometric to VCC, supply tolerance directly scales the full-scale output - using a 1 percent LDO or better keeps the absolute-pressure error contribution from the supply below 1 percent of reading.
Route the analog VOUT trace away from switching-regulator switching nodes, high-current traces, and digital clock lines. Place a small RC low-pass filter (10 kohm + 100 nF) at the MCU ADC input if the trace exceeds 25 mm or passes near noisy regions. Keep the sensor port unobstructed on the PCB side facing the pressure source; do not place tall components within 3 mm of the port.
For MCU ADC interfaces below 3.3 V, add a resistive divider to scale the 4.645 V maximum output to within the ADC reference range. A 10 kohm / 15 kohm divider gives approximately 2.78 V full-scale, leaving margin below 3.3 V. Alternatively, use the 5 V supply as the ADC reference and choose a 5 V-tolerant MCU to preserve full dynamic range.
Do not expose the MPXHZ6116A6T1 port to condensing water, aggressive chemicals, or direct liquid jets - the media-resistant gel is rated for non-corrosive gases and dry air only. If sealed-volume leak testing in humid environments is required, ensure the port side remains dry or add a hydrophobic membrane. Exceeding the 125 C operating range permanently damages the gel coating.
Estimated: at 5 V supply and 6 mA quiescent current, the device dissipates approximately 30 mW. The SOIC-8 package has typical theta_JA around 100 C/W, so self-heating contributes less than 3 C rise. No external heatsinking is required, but ensuring free airflow around the package maintains long-term accuracy.
