MPX4105A Übersicht
A Manifold Absolute Pressure (MAP) sensor is a specialized pressure transducer used in engine control systems to measure the absolute pressure inside the intake manifold. The output voltage correlates to engine load, allowing the ECU to compute the precise amount of fuel required per cylinder. MAP sensors fall under the broader hierarchy of pressure sensors -> transducers -> sensors -> electronic components, and the MPX4105A specifically uses piezoresistive technology within the silicon-based sensor category.
Key features include on-chip signal conditioning that eliminates the need for external amplification, factory calibration that delivers a typical accuracy of 1.5% over 0C to 85C, and a ratiometric analog output referenced to the 5 V supply. The 6-SIP package with female port accepts a 3.4544 mm barbed hose fitting for sealed pneumatic connection, and the through-hole mounting provides robust mechanical attachment suitable for harsh under-hood automotive environments.
Typical applications include automotive engine control MAP sensing, barometric pressure measurement in HVAC and weather stations, industrial pneumatic pressure monitoring, altitude measurement for drones and UAVs, and medical respiratory equipment requiring low-pressure differential sensing. The calibrated output can be fed directly to an ADC without additional analog front-end circuitry.
When designing with this sensor, decouple the VCC pin with a 100 nF ceramic capacitor placed within 5 mm of the device, and route the analog signal over a guarded ground trace. The sensor is ratiometric, so supply noise on VCC directly couples into the output - use a clean, well-regulated 5 V analog rail.

Engine Manifold Absolute Pressure (MAP) Sensing
The MPX4105A is purpose-built for naturally aspirated gasoline engine MAP sensing where intake manifold vacuum at idle drops to roughly 15-30 kPa and rises to atmospheric ~100 kPa at wide-open throttle. Its calibrated 0.3-4.9 V ratiometric output directly correlates to engine load, allowing the ECU to compute injector pulse width without additional analog front-end circuitry. The 1.5% accuracy over 0-85C and on-chip temperature compensation eliminate per-unit calibration, while the barbed port mates with standard 3.5 mm silicone manifold hoses. The through-hole 6-SIP package withstands under-hood vibration and temperature extremes up to 125C.

Barometric Pressure Measurement
In weather stations and HVAC barometric sensing, the MPX4105A provides a calibrated 0.3-4.9 V output across 15-105 kPa that maps directly to atmospheric pressure variation between sea level (~101 kPa) and high altitude (~25 kPa). The on-chip temperature compensation from 0-85C ensures stable readings across daily and seasonal temperature swings, while the ratiometric output rejects 5 V supply noise when paired with a clean analog rail. The through-hole mounting and barbed port simplify integration into outdoor enclosures with sealed hose connections to ambient air.

Industrial Pneumatic Pressure Monitoring
Factory automation systems rely on the MPX4105A to monitor compressed air line pressure in the 15-105 kPa operating range typical of pneumatic actuators and vacuum pick-and-place equipment. The calibrated analog output interfaces directly with PLC analog modules or industrial ADCs without signal conditioning, while the robust 6-SIP through-hole package survives factory floor vibration and temperature. On-chip signal conditioning rejects common-mode industrial noise, and the 1.5% accuracy supports closed-loop pressure control in pick-and-place heads and vacuum grippers.
Empfohlen
Drone / UAV Altitude Measurement
Low-altitude UAVs and hobbyist drones use the MPX4105A as a low-cost barometric altimeter in the 15-105 kPa atmospheric pressure range. The ratiometric analog output feeds directly into the flight controller ADC, providing altitude data with 1.5% accuracy sufficient for hover stabilization and altitude hold up to ~3000 m above sea level. The 6-SIP through-hole package is lightweight (~2 g) and the barbed port accepts small silicone tubing for sealed air reference, while the 5 V supply compatibility matches typical flight controller power rails.

Medical Respiratory Equipment
Medical CPAP and BiPAP machines, as well as spirometers, leverage the MPX4105A's 15-105 kPa range to measure airway pressure during patient breathing cycles. The 1.5% calibrated accuracy and on-chip temperature compensation provide reliable pressure data across patient body temperatures, while the ratiometric analog output interfaces with medical-grade ADCs for real-time pressure waveform capture. The 6-SIP package with barbed port accommodates standard medical tubing for sealed pneumatic connection, and the through-hole mounting supports medical device manufacturing assembly processes.

HVAC Air Flow Monitoring
Building HVAC systems use the MPX4105A to monitor duct static pressure in the 15-105 kPa operating range typical of variable air volume (VAV) boxes and building pressure controllers. The calibrated analog output feeds building automation controllers without external amplification, and the on-chip temperature compensation maintains accuracy across HVAC operating environments from 0C to 85C. The 6-SIP through-hole package with barbed port simplifies field installation with standard pneumatic tubing, while the ratiometric output rejects supply noise from HVAC control panel power rails.

- Through-hole 6-SIP with barbed port for robust pneumatic connection (vs. MPX4250A)
Designhinweise
The MPX4105A requires a clean, well-regulated 5 V supply because its output is ratiometric to VCC. Per the NXP datasheet, supply noise on VCC couples directly into VOUT at the same percentage. Decouple the VCC pin with a 100 nF ceramic capacitor placed within 5 mm of the pin, and add a 10 uF bulk capacitor on the analog rail feeding the sensor. Do not share the sensor's VCC rail with digital switching loads.
Route the analog VOUT trace over a continuous ground plane and keep digital signals (PWM, switching regulator feedback) at least 5 mm away to avoid coupling. Per the NXP datasheet, the sensor output is high-impedance during power-up, so the ADC input must tolerate this state. Place a guard ground trace between VOUT and noisy digital traces for best noise immunity.
Do not apply pressure outside the 15-105 kPa calibrated range - the sensor will produce a clamped output but mechanical overpressure can damage the diaphragm. Per NXP, absolute maximum overpressure ratings must be observed. Do not use the sensor with supply voltages below 4.85 V or above 5.35 V - the output will no longer be ratiometrically accurate. Avoid sealing the port without proper venting in gauge mode configurations.
The MPX4105A is specified for 1.5% accuracy from 0C to 85C and operates up to 125C. In under-hood automotive applications, mount the sensor away from exhaust manifolds and use a heat shield if ambient temperatures exceed 100C. The on-chip temperature compensation corrects for the sensor's own self-heating, but external thermal gradients can introduce error.
