MPX5100AP - 0-100kPa Absolute Pressure Sensor, 6-SIP | NXP
MPN: MPX5100AP ✓ Hoạt độngMPX5100AP Tóm tắt
An absolute pressure sensor is a transducer whose output is referenced to a sealed internal vacuum cavity rather than to ambient atmosphere, so it reports true pressure independent of weather or altitude variation. Absolute pressure sensors sit within the broader MEMS (micro-electromechanical systems) sensor family and operate alongside gauge and differential pressure variants. In the MPX5100 family, the 'A' suffix denotes absolute reference while 'D' (differential) and 'G' (gauge) variants address other reference schemes, all sharing the same ASIC core and pinout.
Key features include ±2.5% maximum pressure error over 0 °C to +85 °C, 1% full-scale-span temperature compensation, and a noise-immune ratiometric output that tracks VCC to compensate for supply variation in microcontrollers with ADC inputs. The 5.0 V single-supply operation draws approximately 10 mA typical supply current, and the 6-SIP package provides port-style mounting with a 0.19 inch (4.93 mm) tube interface for hose or pneumatic connection.
The MPX5100AP uses a patented single-element X-ducer strain-gauge bridge micromachined from silicon and laser-trimmed at wafer level for offset and span calibration. This integrated approach eliminates the need for external compensation networks, op-amps, or trimpots, simplifying firmware development and lowering BOM cost in volume production.
Typical applications include barometric pressure measurement for weather stations and altimeters, HVAC air-flow monitoring, medical respirator and ventilator pressure feedback, industrial process pressure trending, and engine manifold absolute pressure (MAP) sensing in non-automotive engine control. The wide 0 °C to +85 °C compensated temperature range also suits outdoor and industrial enclosures.
When designing with this device, reserve a 0.1 uF bypass capacitor close to the supply pin and connect the output directly to a microcontrollers ADC with adequate input impedance (typically greater than 50 kΩ) to minimize loading error. For barometric altimetry, average multiple ADC samples to filter mechanical and electrical noise that can otherwise couple into the LSB of the conversion.

Ứng dụng tiêu biểu
MPX5100AP phù hợp cho 6 Áp dụngs: Barometric Weather Station, HVAC Air-Flow Monitoring, Medical Respirator Pressure Feedback, Industrial Process Pressure Trending, Engine Manifold Pressure (Non-Automotive) Sensing, Drone Altitude Hold and Variometer.
Barometric Weather Station
The MPX5100AP suits barometric weather stations requiring accurate 15-115 kPa absolute pressure measurement with ratiometric analog output. The +/- 2.5% accuracy from 0 C to 85 C matches typical barometric drift budgets, and the 4.7 V full-scale output at 5 V supply provides ~45 mV/kPa - enough resolution for 0.1 kPa pressure tracking (corresponding to ~8 m altitude change) when read by a 12-bit ADC. Place the sensor away from direct sunlight and use a foam windscreen over the port to suppress wind-pressure transients.

HVAC Air-Flow Monitoring
In HVAC duct monitoring, the MPX5100AP provides a calibrated absolute pressure output for tracking air-handler static pressure and filter loading trends. The ratiometric 0.2 V to 4.7 V output interfaces directly with a 0-5 V ADC input, eliminating the need for instrumentation amplifiers. The 6-SIP axial port accepts standard 4.93 mm tubing for in-duct installation, and the 0 C to +85 C compensation range covers most commercial HVAC environments without additional thermal compensation.

Medical Respirator Pressure Feedback
For medical ventilator and respirator designs, the MPX5100AP delivers calibrated absolute airway pressure feedback within the 15-115 kPa physiological range. The 1 ms response time captures breath-cycle pressure transitions without aliasing, and the ratiometric output simplifies battery-powered designs by tracking supply voltage. The 6-SIP through-hole package supports medical-grade PCB assembly, and the bipolar ASIC conditioning meets the signal-integrity requirements of patient-monitoring firmware.

Industrial Process Pressure Trending
In industrial pneumatic and process-control panels, the MPX5100AP provides absolute pressure telemetry for non-corrosive gas and dry air at pressures up to 115 kPa. The +/- 2.5% accuracy over the 0 C to +85 C compensated range covers typical factory-floor temperature swings, and the 10 mA supply current suits loop-powered designs. The 6-SIP module with axial port allows panel-mount hose connections without custom fixturing, accelerating field deployment.

Engine Manifold Pressure (Non-Automotive) Sensing
For small-engine control modules, engine dynamometers, and stationary genset monitoring, the MPX5100AP provides calibrated manifold absolute pressure (MAP) data within the 15-115 kPa range covering idle through light-load operation. The 1 ms response time tracks throttle transients for fuel-mapping algorithms, and the ratiometric output simplifies analog-front-end design. For automotive-grade MAP sensing, use the MPX5100A-Q1 AEC-Q100 variant instead of the standard MPX5100AP.

Drone Altitude Hold and Variometer
In UAV flight controllers, the MPX5100AP provides lightweight absolute altitude data for altitude-hold and variometer functions at low cost. The 6-SIP through-hole package is unusual for drone applications (most drones use SMD barometers like the BMP280), but the MPX5100AP's 10 mA supply and robust ASIC conditioning remain attractive for tethered or experimental UAV builds. Apply 16x oversampling in firmware to suppress altitude jitter from rotor downwash.

Ghi chú thiết kế
Place a 0.1 uF ceramic bypass capacitor as close as possible to the VCC pin (pin 1) and a 1 uF to 10 uF bulk capacitor on the supply rail near the sensor. The MPX5100AP draws approximately 10 mA typical supply current; if powering from a switching regulator, ensure the LDO post-regulator ripple is below 5 mVpp to prevent pressure reading noise from coupling through the ratiometric output.
Mount the 6-SIP module vertically with the axial port pointing up or outboard for best hose connection. Keep the analog output trace short and routed away from digital switching lines; place a guard ring or ground pour around the sensor to minimize EMI pickup. According to the NXP AN1646 application note, do not place the sensor near heat sources that exceed 85 C without additional cooling - the silicon die and gel fill have thermal limits.
Use an ADC input impedance greater than 50 kΩ to prevent loading error on the MPX5100AP's output stage. Most modern microcontrollers with 12-bit ADC inputs present 50-100 kΩ equivalent input impedance, which is acceptable. For 16-bit or higher resolution ADCs, add an external op-amp buffer (e.g., MCP6001 or TL072) between the sensor output and ADC input to avoid source-impedance-induced gain error.
Estimated: Do not connect the axial port to liquids, corrosive gases, or pressures above 400 kPa - the MPX5100AP uses a silicon gel-isolated diaphragm designed for dry non-corrosive gases only. Exposure to water or oil can permanently damage the sensor. Always include a particulate filter at the port inlet for outdoor deployments to prevent dust contamination. Verify the maximum overload pressure rating in the datasheet before sizing pneumatic connections.
