MPX2200A117 概要
A pressure sensor, also called a pressure transducer, is a device that converts an applied differential or absolute pressure into a proportional electrical signal. The MPX2200A belongs to the MPX family of piezoresistive sensors, which sit in the broader transducer category below analog signal-chain components and above raw MEMS diaphragms. By integrating the strain-gauge bridge, temperature compensation, signal conditioning, and ESD protection on a single monolithic silicon die, NXP produces a calibrated transducer that requires only an external amplifier and ADC to deliver a digital pressure reading.
Key features include a 0 kPa to 200 kPa absolute operating range (approximately 29.01 psi), a typical full-scale span of 40 mV at 10 V excitation with a measured offset trim range that supports zero calibration, an industry-leading accuracy of ±0.25 %V FSS when externally amplified and corrected, and a temperature-compensated range of 0 °C to +85 °C. The integrated laser-trimmed thin-film network calibrates span and offset over the compensated temperature range, eliminating most software polynomial correction in the host MCU.
Architecturally, the MPX2200A employs a proprietary Monolithic Silicon Strain Gauge (MSSG) process that places the piezoresistors on a chemically etched silicon diaphragm. The diaphragm deflection is proportional to applied pressure; the resulting bridge imbalance is amplified by internal thin-film resistors and laser-trimmed for span accuracy. The result is a ratiometric analog output with low temperature coefficient of span (< -1.0 %V FSS over 0 to 85 °C) and stable long-term repeatability.
Typical applications include medical respiration monitors, HVAC air-flow controllers, industrial process control loops, altitude measurement for drones and avionics, and consumer weather stations. In a CPAP or ventilator use-case, the 0 to 200 kPa absolute range directly maps to airway pressure while the 10 V excitation span simplifies the front-end ADC reference design.
Engineers should treat the 40 mV full-scale span as a low-level signal: place a low-offset, low-noise instrumentation amplifier within 50 mm of the sensor pins, use a Kelvin connection to the excitation source, and add a small RC filter (typ. 1 kohm + 10 nF) to suppress EMI. Because the silicon die is sensitive to humid environments, the case-117 housing should be sealed with an O-ring in any liquid-coupled installation.

主な用途
MPX2200A117 の用途: 7 件s: Medical CPAP / Ventilator Airway Pressure, HVAC Duct Airflow Pressure, Drone and UAV Altitude Reference, Industrial Process Pressure Monitoring, Consumer Weather Station, Respiratory / Spirometer Flow Sensing, Appliance Water-Level and Pump Pressure Sensing.
Medical CPAP / Ventilator Airway Pressure
The MPX2200A117's 0 to 200 kPa absolute range (approx. 29.01 psi) maps directly onto CPAP and bilevel ventilator circuit pressures, which typically operate between 4 and 20 cmH2O but may exceed 200 kPa during single-fault condition. Its on-chip temperature compensation over 0 to +85 °C holds span accuracy within -1.0 %V FSS across long mask-wear sessions in room-temperature to warm-bed environments, avoiding patient-arousing drift. The 40 mV span at 10 V excitation amplifies cleanly through an INA128 instrumentation amplifier placed within 50 mm of the sensor pins; a 1 kohm + 10 nF RC filter suppresses ventilator motor EMI. This eliminates the need for second-order software polynomial correction at the host MCU and supports a 12- to 16-bit ADC front-end.
おすすめ
HVAC Duct Airflow Pressure
In variable-air-volume (VAV) HVAC actuators and differential pressure transmitters, the MPX2200A117's 200 kPa absolute range covers the 0 to 1.5 inH2O duct sensing requirements with significant headroom, allowing a single part to span residential, commercial, and light-industrial systems. Its internal -1.0 %V FSS span TC over 0 to +85 °C eliminates the need for field recalibration as building ventilation cycles through cold-night to hot-day exposures. The 4-SIP case-117 axial port accepts standard 4 mm ID tubing via crimped barbed fitting, simplifying duct-tap plumbing. With 40 mV full-scale output at 10 V, an OPA2333 dual op-amp front-end delivers a 0 to 3.3 V rail for a low-cost MCU ADC, replacing higher-cost differential transducers.
おすすめ
Drone and UAV Altitude Reference
The MPX2200A117 suits small-UAV altimetry because 1 kPa of pressure shift corresponds to about 100 m of altitude in the troposphere, so its 200 kPa full-scale absolute range covers 0 to 10 000 m of flight envelope with margin. The internal temperature compensation lets it ride along on outdoor flights from -10 °C to +50 °C without the host MCU applying span corrections, freeing CPU cycles for flight-control loops. The 40 mV span at 10 V excitation delivers -40 mV to +40 mV differential signal that pairs well with a low-cost AD8421 instrumentation amplifier; a 6-axis IMU pairs to remove high-frequency vibration before the altitude low-pass. The 4-SIP housing adds less than 1 g of mass, which is critical for sub-250 g UAVs.
おすすめ
Industrial Process Pressure Monitoring
Process control loops in the 0 to 200 kPa band - chilled-water supply lines, gas-blending skid feed, and clean-room differential pressure - benefit from the MPX2200A117's ratiometric 40 mV span at 10 V, which pairs with 4-20 mA HART transmitter front ends. The internal -1.0 %V FSS span TC and laser-trimmed thin-film compensation package deliver IEC 61298-2 typical accuracy budgets without per-unit software calibration. The 4-SIP housing's PCB through-hole assembly supports hand-prototype repair, useful for instrumentation retrofit applications. With ±0.25 %V FSS accuracy after external amplification, the sensor can meet ISA-style instrumentation requirements for non-redundant pressure loops.
おすすめ
Consumer Weather Station
The MPX2200A117's 0 to 200 kPa absolute range maps to barometric pressure in the 870 to 1084 hPa weather-station band with a comfortable 1.5x headroom for storm anomalies. Its on-chip temperature compensation removes the dominant error source of low-cost weather sensors, allowing a $5 BOM MCU like an STM32G071 to drive a graphical display without polynomial lookup. The 10 V excitation span can be reduced to 3.3 V with proportional span loss, enabling direct ADC reading on coin-cell designs. The 4-SIP case-117 port accepts standard hose-barb fittings for mounting in a vented weatherproof enclosure.
おすすめ
Respiratory / Spirometer Flow Sensing
Handheld spirometers and peak-flow meters that quantify patient lung capacity benefit from the MPX2200A117's 0 to 200 kPa absolute range when paired with a Venturi or differential-pressure flow head. Its 40 mV span at 10 V is amplified to a usable 0 to 3.3 V level by an AD8221 instrumentation amplifier, then sampled at 1 kHz by a low-cost 12-bit ADC. The on-chip temperature compensation holds accuracy across the 16 to 35 °C usage band without per-session calibration in the clinic. The compact 4-SIP housing fits inside disposable flow-head enclosures, simplifying medical-grade cleaning and reducing per-test BOM cost.
おすすめ
Appliance Water-Level and Pump Pressure Sensing
Appliance OEMs use the MPX2200A117 in dishwasher, washing-machine, and water-pump systems to monitor 0 to 200 kPa supply pressures and detect inlet blockages. The internal temperature compensation keeps the reading stable across cold-rinse to hot-sanitize cycles, and the 4-SIP port simplifies plumbing integration with a single hose barb. The 10 V excitation can be derived from the appliance's 12 V rail and regulated to 10 V by a low-cost LDO, eliminating external 24 V supplies. Compared to a mechanical pressure switch, this sensor delivers a continuous analog signal that supports variable-speed pump control and quiet operation.

設計ノート
The MPX2200A117 outputs a 40 mV ratiometric bridge signal at 10 V excitation. Use a low-offset, low-noise instrumentation amplifier such as INA128 or AD8421 placed within 50 mm of the sensor pins to keep the differential routing short. Add a 1 kohm + 10 nF RC low-pass filter on each leg to suppress high-frequency EMI from switching regulators or motor drivers common in the appliance installations. Guard the bridge with a driven shield if the cable to the ADC board exceeds 100 mm in length.
The MPX2200A117 is internally compensated over 0 °C to +85 °C; design thermal conduction such that the housing ambient stays within that band. Estimated: at 1 mA excitation current, the bridge dissipates about 10 mW at 10 V, which produces negligible self-heating. Most self-heating error in practice comes from the external amplifier - keep the INA package at the same ambient air flow as the sensor. For outside installations, use an opaque, vented enclosure to avoid solar absorption errors.
Pour a hatched thermal copper pad under the MPX2200A117 4-SIP pins to dissipate bridge heat and provide a low-impedance ground return for the Vs supply. Use a single-point star ground at the sensor pin 3 and break the digital ground plane to keep ADC switching currents out of the bridge reference. Keep all four leads the same length and oriented vertically through the board for clean through-hole hand-soldering. Estimated: the recommended pad spacing is 2.54 mm (0.1 in) pin-to-pin matching the SIP1.27 mm body pitch.
Do not power the MPX2200A117 above 20 V; the bridge will saturate and lose internal compensation calibration. Avoid liquid ingress into the pressure port - the case-117 housing is intended for dry, non-corrosive gases. For fluid sensing, pair with a sealed isolator diaphragm and silicone oil fill. Wire pin 1 (Vs+), pin 2 (Vout+), pin 3 (GND), and pin 4 (Vout-) per the datasheet pinout; reversing Vs+ and GND permanently damages the bridge. Calibrate zero pressure offset at room temperature in software before applying span correction.
