MPX4115A117 Descripción general
What is an absolute pressure sensor? An absolute pressure sensor measures pressure referenced to a sealed vacuum reference inside the die, so its output indicates true absolute pressure regardless of ambient barometric changes. Absolute sensors sit within the broader category of pressure transducers and IC-based environmental sensors, used wherever a system needs ambient atmospheric or sealed-cavity pressure data rather than gauge (relative-to-atmosphere) or differential (between two ports) readings.
Key features of the MPX4115A117 include 1.5% maximum accuracy over 0 °C to 85 °C, integrated bipolar op-amp signal conditioning plus thin-film resistor networks on the same silicon die, and a typical response time of 1.0 ms. The on-chip calibration eliminates the need for external trimming components, simplifying board-level implementation. Media-resistant construction and gel isolation protect the sensing element from humid and dirty air streams.
Typical applications include automotive engine control unit (ECU) manifold absolute pressure (MAP) sensing, altimeters and barometric pressure measurement in weather stations and GPS modules, industrial vacuum monitoring, HVAC altitude compensation, and consumer wearables that require barometric pressure data. The wide temperature range and calibrated analog output also make it suitable for drone altitude hold and handheld instruments.
When designing with the MPX4115A117, ensure the supply is well-decoupled with a 10 µF bulk and 0.1 µF ceramic capacitor near the VCC pin. The ratiometric output requires an ADC reference tied to the same 5 V rail for accurate conversion. For best long-term accuracy, keep the inlet port vertical and shield the device from direct sunlight to minimize thermal gradients.

Aplicaciones típicas
MPX4115A117 es adecuado para 8 aplicacións: Automotive Manifold Absolute Pressure (MAP) Sensing, Barometric Altimeter for Handheld GPS / Wearables, Industrial Vacuum and Process Monitoring, HVAC Altitude Compensation, Weather Station / Barometric Pressure Logger, Drone Altitude Hold / Altimeter, Medical Respiratory / CPAP Pressure Monitoring, Barometric Reference for Test & Measurement.
Automotive Manifold Absolute Pressure (MAP) Sensing
The MPX4115A117 is well suited to manifold absolute pressure sensing in engine control units where it measures intake-manifold vacuum and boost on naturally-aspirated and turbocharged gasoline engines. Its 15-115 kPa span maps cleanly to manifold pressure variations from heavy vacuum (~20 kPa at idle) to mild boost (~115 kPa at wide-open throttle), and the ratiometric analog output feeds directly into a 5 V ADC channel on the ECU. On-chip temperature compensation removes the need for per-unit trimming across -40 °C to +125 °C engine-bay environments. Compared with discrete bridge designs the integrated op-amp signal chain saves board area and improves long-term stability under thermal cycling.

Barometric Altimeter for Handheld GPS / Wearables
The MPX4115A117's wide 15-115 kPa range and 0.2-4.8 V analog output make it a direct match for barometric altimeters inside handheld GPS units, two-way radios, and outdoor wearables. At sea level the sensor outputs about 4.21 V which the host MCU's ADC converts to 101.3 kPa; software then derives altitude from the barometric formula h = 44330 × (1 - (P/101.325)^(1/5.255)). The on-chip signal conditioning avoids external op-amps, helping fit a sensor interface in a small footprint. The factory calibration to ±1.5% over 0 °C to 85 °C is sufficient for consumer-grade altitude readout (±8 m at sea level).
Recomendado
Industrial Vacuum and Process Monitoring
For industrial vacuum pumps and sealed process lines, the MPX4115A117 monitors sub-atmospheric to slightly above-atmospheric pressures on plant-floor vacuum systems. The 15-115 kPa span starts low enough to read vacuum down to ~15 kPa absolute, and the amplified 0.2-4.8 V output can drive a long analog cable back to a control cabinet without additional buffering. The robust Case 867-08 6-SIP housing with gel-isolated media-compatible port withstands humid or particulate-laden air streams typical of factory environments. Engineers typically pair it with a 4-20 mA current loop transmitter to translate the output for legacy PLCs.
Recomendado
HVAC Altitude Compensation
HVAC systems deployed at high altitude need to compensate combustion-air and refrigeration pressures for thinner atmosphere, and the MPX4115A117 offers an easy analog interface for the controller. Mounted near the air handler, its 15-115 kPa range covers from near sea level to 2 800 m equivalent pressure with linear output that the BMS can sample per thermostat cycle. The integrated calibration reduces per-board trimming at manufacturing, simplifying production for white-goods OEMs. Compared with barometric digital sensors it is also lower cost, important in price-sensitive HVAC applications.
Recomendado
Weather Station / Barometric Pressure Logger
Hobby and prosumer weather stations benefit from the MPX4115A117's calibrated 15-115 kPa absolute pressure span, which converts directly to a barometric reading without offset compensation. The ratiometric analog output scales naturally with the supply rail, so a 3.3 V or 5 V MCU ADC reference sees a proportional reading. Power consumption is modest enough for battery-powered weather loggers running off coin cells or solar harvesters. Solar shielding is recommended to avoid temperature-gradient errors during midday exposure.
Recomendado
Drone Altitude Hold / Altimeter
In multirotor drones the MPX4115A117 provides absolute altitude feedback to the flight controller for altitude-hold modes, leveraging the full 15-115 kPa span to resolve altitude changes of 1 m or better. The 1 ms typical response time is fast enough for indoor-barometer altitude tracking at moderate descent/ascent rates, and the SIP through-hole mount survives vibration better than surface-mount alternatives on stiff drone frames. Combined with GPS altitude data, sensor fusion improves altitude-hold accuracy beyond either source alone. Choose an automotive-grade equivalent such as the MPX4250A for high-vibration platforms.
Recomendado
Medical Respiratory / CPAP Pressure Monitoring
For medical respiratory equipment such as CPAP and BiPAP machines the MPX4115A117 offers a calibrated, low-noise analog pressure channel that monitors mask pressure in the 0-115 kPa range. The integrated op-amp signal chain keeps noise low enough for closed-loop pressure control, and the isolated media port protects the die from humidity in the patient airflow path. While not AEC-Q100 qualified, the 15-115 kPa span and 0.2-4.8 V scaled output are well matched to typical mask-pressure control loops. Designers should add a software self-test routine to verify calibration at startup.
Recomendado
Barometric Reference for Test & Measurement
In laboratory instrumentation the MPX4115A117 acts as a stable absolute-pressure reference for calibrating flow meters, leak testers, and gas-analyzer systems. The 1.5% accuracy and ±1 kPa resolution at the 5 V ADC output are sufficient for general-purpose barometric compensation, and the SIP form factor simplifies hand-wired test fixtures. Long-term stability is adequate for production-line testing where reference standards are recalibrated annually. Engineers often pair it with a high-resolution ADC such as the MAX1320ECM+ for ≤0.1 kPa repeatability.

Notas de diseño
Estimated: Power the MPX4115A117 from a regulated 5 V rail capable of sourcing ≥10 mA. Place a 10 µF tantalum (or electrolytic) bulk capacitor plus a 0.1 µF ceramic decoupling cap directly across VCC (pin 1) and GND (pins 2 and 3) within 5 mm of the package. Inductive supply switching noise will couple into the analog output, so isolate the 5 V analog rail from noisy digital rails with a ferrite bead or LDO post-regulator.
Route the VOUT (pin 4) trace over a continuous ground plane and keep it away from switching nodes and high-current traces. Add a 100 Ω series resistor plus 100 nF capacitor to ground on VOUT if the trace exceeds 50 mm, to form a 1.6 µs RC low-pass filter that suppresses digital switching noise without attenuating the 1 ms sensor response. Use a SAR ADC input buffer with ≥10 MΩ input impedance so it does not load the ratiometric output.
Estimated: The MPX4115A117 die measures differential pressure internally referenced to a sealed vacuum; do not apply excessive vacuum or positive pressure outside the 0-200 kPa absolute range or the gel-isolated port may be damaged. Avoid exposing the port to condensing humidity or direct water spray, since moisture ingress can corrupt the calibration and offset the output voltage. For long hose runs to the pressure source, use 1.5-3 mm ID tubing and keep lengths under 1 m to prevent dynamic lag.
If the design is re-spun for surface-mount assembly, choose the smaller MPXH6300A or BMP280 instead - the MPX4115A117's 6-SIP through-hole footprint is incompatible with standard SMT reflow lines and will require wave soldering or hand placement. For through-hole boards, drill 0.9 mm pin holes, allow 2.5 mm pad-to-pad pitch, and provide clearance for the top-mounted pressure port above the board surface.
Estimated: Self-heating of the MPX4115A117 is modest at 5 V (≈40 mW internal dissipation at 8 mA typical supply), but thermal gradients across the housing can appear as offset drift. Mount the sensor away from heat sources like power resistors or DC-DC converters, and provide copper pour on the SIP pads to spread heat. For <0.1 kPa repeatability in outdoor weather-logger applications, solar-radiation shielding is essential.
