MPX4115AP Übersicht
An absolute pressure sensor is a transducer that measures pressure referenced to a sealed vacuum rather than ambient atmosphere, which makes it ideal for barometric and altitude applications where the absolute atmospheric pressure must be known regardless of weather or altitude. Absolute pressure sensors belong to the broader class of piezoresistive pressure sensors, which are themselves a subset of MEMS (Micro-Electro-Mechanical Systems) sensors. The MPX4115 family integrates a Wheatstone-bridge strain-gauge network with bipolar op-amp signal conditioning and laser-trimmed thin-film calibration resistors, producing a high-level linear analog output directly usable by an ADC or microcontroller without external amplification.
Key features of the MPX4115AP include a sensitivity of 45.9 mV/kPa, 5.1 V typical supply voltage with 4.85 V to 5.35 V operating range, 6 mA typical supply current, an output range of 0.20 V to 4.80 V, and a maximum operating temperature of 125 C with a minimum of -40 C. The device is also notable for its 0.2% to 1.5% linearity, temperature-compensated output over 0 C to 85 C, and low error band across the compensated range.
Architecturally, the MPX4115AP uses a diffused silicon diaphragm that flexes proportionally to applied absolute pressure. The resulting strain changes the resistance of an on-die piezoresistive Wheatstone bridge, which is then amplified by an on-chip bipolar op-amp stage and scaled by laser-trimmed thin-film resistors to produce the factory-calibrated 0.2-4.8 V output. This integrated approach eliminates the need for external signal conditioning, op-amps, or calibration lookup tables in the host MCU for non-precision use cases.
Typical applications include altimeters and barometers for weather stations, drones and aviation, MAP (Manifold Absolute Pressure) sensing in engine control units, HVAC pressure monitoring, weather instruments, medical respirators and ventilators, and consumer altitude/weather meters. Its 15 kPa lower bound (roughly the pressure at 11 km altitude) makes it suitable for high-altitude avionics as well as surface barometric readings.
When designing with this part, ensure the supply voltage is well regulated and low-noise because the output is ratiometric to VCC. Decouple VCC with a 100 nF ceramic capacitor close to the supply pin and route analog signals away from high-current switching traces to preserve the 0.2-4.8 V output's 1% accuracy band.

Typische Anwendungen
MPX4115AP ist geeignet für 6 Anwendungs: Barometric Weather Station, Drone / UAV Altimeter, Engine MAP (Manifold Absolute Pressure) Sensing, Medical Respirator / Ventilator Pressure Monitoring, HVAC Pressure Monitoring, Consumer Altimeter / Weather Meter.
Barometric Weather Station
The MPX4115AP's 15-115 kPa absolute range covers the full atmospheric pressure spectrum from sea-level (~101 kPa) down to ~11 km altitude, and its 45.9 mV/kPa sensitivity delivers roughly 4.6 V of swing across the operating window - well within the 0.2-4.8 V calibrated output. Place the sensor on the PCB with the 4.93 mm tube port venting to ambient, power it from a clean 5.1 V LDO with a 100 nF decoupling cap, and feed VOUT directly into a 12-16 bit ADC whose reference is also tied to the same 5.1 V rail to preserve ratiometric accuracy. The on-chip temperature compensation over 0-85 C removes the need for software lookup tables in outdoor enclosures. Compared to discrete piezoresistive bridges, the integrated op-amp and thin-film calibration simplify the BOM to just the sensor, decoupling caps, and ADC. Trade-off: long-tube weather stations should add a hydrophobic filter to keep moisture off the diaphragm.

Drone / UAV Altimeter
For multirotor and fixed-wing UAVs, the MPX4115AP's 15 kPa lower bound covers service ceilings beyond 10 km altitude, while its 45.9 mV/kPa sensitivity supports sub-meter altitude resolution when oversampled by a 16-bit ADC. Connect VOUT to the flight controller's ADC input through an RC low-pass filter (~10 kHz cutoff) to suppress propeller vibration noise coupling into the pressure port tube. Power the sensor from a regulated 5 V rail shared with the FC's analog reference for ratiometric accuracy. Unlike ultrasonic or lidar altimeters, the MPX4115AP measures absolute altitude independent of ground texture, and unlike GPS it works indoors and at low altitude. The trade-off is susceptibility to wind gusts across the tube port - mount the sensor inside a static-pressure chamber for stable readings in flight.
Empfohlen
Engine MAP (Manifold Absolute Pressure) Sensing
The MPX4115AP's 15-115 kPa range matches typical gasoline-engine MAP requirements (20-105 kPa at idle to wide-open-throttle), and its 5.1 V ratiometric output interfaces directly with ECU ADCs. Mount the sensor with the 4.93 mm tube plumbed into the intake manifold via a vacuum hose, and use o-rings rated for gasoline vapor. The 0.2-4.8 V swing and on-chip temperature compensation deliver stable readings across engine bay temperatures from -40 C to +125 C, with factory calibration cutting the ECU's per-unit compensation work. Compared to MAP sensors purpose-built for engines (e.g. MPX4250), the MPX4115AP trades pressure range upper bound (115 kPa vs ~250 kPa) for higher sensitivity per kPa, which improves low-load resolution. Trade-off: for boosted engines above 115 kPa, choose a higher-range MAP sensor.

Medical Respirator / Ventilator Pressure Monitoring
The MPX4115AP's 0.2-4.8 V calibrated output and on-chip signal conditioning simplify medical-device designs where analog front-end complexity must be minimized. Its 15-115 kPa operating window covers both adult ventilator airway pressures (~4-40 kPa) and barometric pressure variations in portable CPAP/BiPAP machines. Power the sensor from a regulated 5 V medical-grade isolated supply and route VOUT through an instrumentation-grade op-amp if higher noise immunity is required. The integrated temperature compensation over 0-85 C and factory calibration help meet IEC 60601 accuracy requirements without per-unit trimming. Compared to discrete bridge sensors, the MPX4115AP shortens design-validation cycles and reduces BOM count, but note that medical applications often require additional redundancy and isolation not provided by the bare sensor.
Empfohlen
HVAC Pressure Monitoring
The MPX4115AP's 15-115 kPa absolute range covers residential and commercial HVAC duct static-pressure measurements (~0-500 Pa typical) when referenced through a pressure tap, and its on-chip temperature compensation maintains accuracy across rooftop unit environments. Power from the HVAC 24 VAC control board through a 5 V isolated regulator and feed VOUT to the building-management ADC. The 6-SIP Case 867B-04 module mounts through-hole on the control board for rugged industrial installations. Compared to differential pressure transducers used in HVAC, the absolute-pressure MPX4115AP trades the ability to ignore ambient barometric drift for simpler single-port plumbing. Trade-off: pair with an altimeter-correction algorithm if altitude effects on absolute readings must be removed.
Empfohlen
Consumer Altimeter / Weather Meter
Handheld altimeters and weather meters benefit from the MPX4115AP's small 6-SIP footprint, low 6 mA supply current, and on-chip calibration - all of which shrink the analog front-end to just a battery, regulator, ADC, and display. The 0.2-4.8 V swing covers the full -400 m to +9 km altitude range with comfortable margin, and the 45.9 mV/kPa sensitivity simplifies the firmware's altitude conversion to a single multiply-add. Power the sensor from a 3.3-5 V LDO and average multiple ADC samples to suppress barometric noise. The Case 867B-04 tube port fits standard dust-filter housings used in consumer weather instruments. Trade-off: the through-hole SIP package is taller than SMD alternatives, so choose MPXAZ4115A or surface-mount MPX series variants for slim consumer enclosures.

Designhinweise
Power the MPX4115AP from a low-noise 5.1 V LDO with a 100 nF ceramic decoupling capacitor placed within 5 mm of the VCC pins (1 and 2). Because the output is ratiometric to VCC, tie the ADC reference voltage to the same 5.1 V rail; otherwise absolute pressure readings will drift by the same percentage as the supply. Avoid switching regulators that inject >50 mV ripple onto VCC, since this couples directly into the analog output and degrades the 0.2-4.8 V calibrated swing accuracy.
Do not apply voltages outside the 4.85 V to 5.35 V supply range - the on-chip op-amp is not designed for 3.3 V operation and accuracy will degrade below the datasheet spec. Do not connect the NC pins (5 and 6) to any signal or supply; they are reserved for factory calibration trims. Do not subject the pressure tube to direct water spray; add a hydrophobic filter or sintered bronze port protector if exposed to moisture. Do not assume pin 1 is VCC on all variants - always cross-reference the SIP orientation mark against the latest datasheet revision before soldering.
Route VOUT as a guarded analog trace away from digital switching lines (PWM, I2C clock, switching FET gates) to avoid coupling noise into the high-impedance sensor output. Place a 10 kHz RC low-pass filter (10 kohm + 1 nF) on VOUT for noise-sensitive applications. Mount the sensor with the tube port venting to ambient in a static-pressure chamber for moving-vehicle or drone applications to suppress wind/dynamic pressure effects on the diaphragm.
Estimated: at 6 mA supply current and 5.1 V supply, the MPX4115AP dissipates ~30 mW internally. With a typical through-hole SIP thermal resistance of ~150 C/W, junction temperature rise above ambient is ~4.5 C, so no heatsink is required. The sensor is calibrated over 0-85 C, so for outdoor enclosures add a foam windscreen around the tube port to block direct sunlight and keep the diaphragm within the compensated band.
