MPXAZ6115AC6T1 Présentation
An absolute pressure sensor is a transducer that outputs a voltage proportional to pressure referenced to a sealed internal vacuum rather than ambient atmosphere. Within the broader taxonomy, the MPXAZ6115AC6T1 is a MEMS (micro-electro-mechanical systems) sensor, then a piezoresistive silicon pressure transducer, then a board-mount pressure sensor family, and finally a power-management-adjacent signal-conditioning device. This category of part is essential wherever a clean, temperature-compensated analog pressure signal must be derived directly from a microcontroller ADC without external amplification.
Key features include on-chip bipolar op-amp circuitry and thin-film resistor networks for temperature compensation, an integrated single-port pressure inlet for tube attachment, and a calibrated ratiometric analog output that simplifies ADC sampling from a 5 V supply. The MPXAZ6115AC6T1 also provides media-resistant packaging suitable for non-corrosive dry-gas applications. The on-chip signal conditioning removes the need for external instrumentation amplifiers, which reduces BOM cost and PCB area in cost-sensitive designs.
The MPXAZ6115AC6T1 uses advanced micromachining to combine a piezoresistive strain-gauge bridge with bipolar op-amp signal conditioning and laser-trimmed thin-film compensation resistors. According to the manufacturer datasheet, the device provides a near-linear transfer function across its full pressure range with minimal temperature drift over the rated operating range. The integrated vacuum reference (absolute mode) ensures stable readings regardless of barometric pressure changes.
Typical applications include automotive manifold absolute pressure (MAP) sensing, HVAC pressure monitoring, weather-station barometric measurement, altimeter reference designs, and industrial pneumatic system monitoring. The integrated compensation makes it particularly well-suited to drop-in designs where calibrated performance is required without a lengthy development cycle.
When designing with this device, ensure that the supply voltage stays within 4.75 V to 5.25 V for specified accuracy and that the output load impedance remains high enough to avoid loading the internal op-amp buffer. Tube fitting should be limited to dry, non-corrosive media because the port is not rated for liquid or aggressive chemicals.

Applications typiques
MPXAZ6115AC6T1 convient pour 6 applications: Automotive Manifold Absolute Pressure (MAP) Sensing, HVAC Pressure Monitoring, Barometric Altimeter Reference, Weather Station / Barometric Pressure Logger, Industrial Pneumatic System Monitoring, Consumer Appliance Pressure Sensing.
Automotive Manifold Absolute Pressure (MAP) Sensing
The MPXAZ6115AC6T1's 15 to 115 kPa absolute range and 0.2 V to 4.7 V ratiometric analog output make it a strong match for engine manifold absolute pressure (MAP) sensing on naturally aspirated and lightly turbocharged gasoline engines. The full-vacuum-to-atmospheric range (15 kPa to ~101 kPa) cleanly covers idle and wide-open-throttle conditions, and headroom up to 115 kPa captures moderate boost. Placed on the intake manifold with a short 3.17 mm tube run to the top-port inlet, the on-chip temperature compensation maintains accuracy across underhood thermal swings, and the buffered output drives an ECU ADC directly without external instrumentation amplifiers. Unlike bare piezoresistive bridges, the integrated op-amp and thin-film compensation remove a calibration step in production.

HVAC Pressure Monitoring
The MPXAZ6115AC6T1 is well-suited to HVAC system pressure monitoring in the 15 to 115 kPa absolute band, which aligns with low-side refrigerant and air-handling pressure transducer requirements in ducted and split-system designs. The single 5 V supply integrates directly with HVAC controller boards that already host a 5 V rail, and the 0.2 V to 4.7 V ratiometric output pairs cleanly with low-cost 10-bit ADCs. The 8-SMD top-port package accepts standard 3.17 mm tubing for inline pneumatic tap-off, and the on-chip conditioning removes amplifier stages that would otherwise be required with bare strain-gauge bridges. The media-resistant package tolerates dry filtered air, which is the typical HVAC working fluid.

Barometric Altimeter Reference
The MPXAZ6115AC6T1's absolute 15 to 115 kPa range is ideal for barometric altimeter reference designs in portable navigation, weather stations, and drone telemetry. The lower bound of 15 kPa covers altitudes up to approximately 13 km, which is well beyond hobby-drone and consumer-aviation operating ceilings. The 0.2 V to 4.7 V ratiometric output, sampled at 5 V reference, gives approximately 45 mV per kPa - enough resolution for altitude calculations down to roughly 30 meters when paired with a 12-bit ADC. The 8-SMD top-port package supports sealed enclosure designs with a tube nipple, and the on-chip temperature compensation reduces altitude drift in cold-soak and full-sun conditions.

Weather Station / Barometric Pressure Logger
The MPXAZ6115AC6T1's absolute pressure reference and on-chip temperature compensation make it suitable for weather-station barometric pressure logging where trends (rising/falling) and absolute readings both matter. The 15 to 115 kPa range covers sea-level reference (101.325 kPa) with margin for both high- and low-pressure weather events. The 8-SMD top-port SMD package allows compact PCB integration inside weatherproof enclosures with a sealed tube nipple, and the 5 V analog ratiometric output pairs with low-power MCUs that already include 5 V-tolerant ADC channels. Unlike buses requiring digital calibration, the device outputs a calibrated linear voltage that simplifies firmware.
Recommandé
Industrial Pneumatic System Monitoring
The MPXAZ6115AC6T1 is well-matched to industrial pneumatic system monitoring at line pressures up to 115 kPa, including low-pressure compressed-air networks, vacuum-pump monitoring, and pick-and-place equipment pneumatic circuits. The top-port 3.17 mm tube inlet accepts standard pneumatic fittings, and the 8-SMD gull-wing package solders to standard SMT lines. The 5 V single-supply operation draws modest current and integrates with industrial controller 5 V rails without additional regulation. The on-chip bipolar op-amp signal conditioning eliminates external amplification, which reduces BOM and PCB area for high-channel-count pneumatic monitoring boards.
Recommandé
Consumer Appliance Pressure Sensing
The MPXAZ6115AC6T1 fits consumer appliances that need low-pressure sensing, including washing-machine water-level sensing via air-trap tubes, vacuum cleaner suction monitoring, and coffee-machine pressure profiling in espresso machines. The 15 to 115 kPa absolute range covers the negative-to-positive gauge pressures typical in these appliances when referenced to the sealed vacuum inside the package. The 8-SMD top-port package is small enough for appliance main boards with tight mechanical packaging. The integrated on-chip signal conditioning and temperature compensation reduce calibration overhead in high-volume consumer manufacturing.

Notes de conception
Power the MPXAZ6115AC6T1 from a regulated 5.0 V (±0.25 V) supply. According to the STMicroelectronics datasheet, the output is ratiometric to the supply, so any ripple or drift on VCC directly couples to the pressure reading. Decouple VCC to ground at the device pins with a 100 nF ceramic capacitor in parallel with a 10 uF bulk capacitor. Brown-out conditions below 4.75 V produce non-linear output and should be avoided; add a power-on delay so the MCU does not sample pressure before the internal op-amp stabilizes.
Place the MPXAZ6115AC6T1 at the edge of the PCB with the top-port inlet exposed to atmosphere through a sealed tube nipple or O-ring. According to STMicroelectronics application guidance, route the analog output trace away from switching nodes and high-current paths to avoid injected noise on the ADC input. Provide a low-impedance ground pour directly under the package thermal/exposed pad to reduce supply-noise coupling. Add a guard trace around the output trace if the board is exposed to high-humidity or condensing environments.
Do not connect the MPXAZ6115AC6T1 output to a low-impedance load; according to the STMicroelectronics datasheet the internal op-amp buffer is rated for high-impedance ADC input only, and loading it reduces accuracy. Do not apply liquid or corrosive media to the port - the package is rated for dry, non-corrosive gas only. Do not assume that any pinout variant of the MPXAZ6115 family is pin-compatible with the AC6T1 top-port SMD footprint; verify the SOP-8 vs side-port vs through-hole pinout before substituting. Sample the output with an ADC reference that matches the 5 V supply to preserve calibrated accuracy.
