MPXM2202AS 개요
A piezoresistive pressure sensor is a micro-electro-mechanical (MEMS) device in which a silicon diaphragm with diffused strain gauges converts applied pressure into a proportional change in resistance. The MPXM2202AS integrates the sensing die, on-chip temperature compensation network, and signal-conditioning resistors in a single surface-mount module, allowing direct interface to an external ADC or instrumentation amplifier. Within the broader sensor taxonomy, it sits as: pressure sensor -> MEMS sensor -> transducer -> sensor IC -> semiconductor. The MPX2202/MPXM2202 family is the legacy industrial/medical successor to the original Motorola MPX2000 series piezoresistive cells.
Key features include 0 mV to 40 mV full-scale output (typ. 0.2 mV/kPa sensitivity), 10 V typical excitation, on-chip temperature compensation across 0C to 85C, and an absolute pressure reference sealed inside the package. The 5-pin M-PAC package simplifies PCB layout compared to the larger unibody MPX2202GP variant, while preserving the same Wheatstone-bridge pinout. The sensor is intended for clean, dry, non-corrosive gases.
The MPXM2202AS relies on a single-axial piezoresistive bridge: four ion-implanted resistors on a silicon diaphragm form a Wheatstone configuration, balancing at 0 kPa and unbalancing linearly with applied pressure. The on-chip compensation network cancels the first-order temperature coefficient of the bridge, allowing raw mV output to be read directly with reasonable accuracy over the 0-85C range.
Typical applications include medical inhalers and patient monitors, HVAC pressure transmitters, altimeters and barometric instruments, industrial process control, and pneumatic system monitoring. For battery-powered designs, consider newer I2C/SPI digital sensors such as the NXP MPL3115A2 or the Bosch BMP280; the MPXM2202AS is best suited to systems that already have a stable 10 V analog supply and an ADC front end.
When designing with this part, route the high-impedance bridge outputs on a guard trace or shield and place the ADC sample-and-hold within 50 mm of the output pins. Apply the 10 V excitation through a low-noise LDO such as the TPS7A4701 to avoid bridge self-heating drift.

일반적인 애플리케이션
MPXM2202AS 적합 용도: 7 애플리케이션s: Medical Inhaler Pressure Monitoring, HVAC Duct Pressure Transmitter, Barometric Altimeter / Weather Station, Industrial Process Pressure Monitor, Pneumatic System Leak Testing, Patient Monitoring / Ventilator Side Stream, Gas Chromatograph Carrier Pressure Sense.
Medical Inhaler Pressure Monitoring
The MPXM2202AS suits medical inhaler and respiratory equipment where 0-200 kPa absolute pressure reflects delivered lung pressure. Its 0.2 mV/kPa sensitivity and 10 V excitation produce a 40 mV full-scale signal that feeds directly into an instrumentation amplifier such as the INA128, preserving the dynamic range needed for breath-pattern analysis. The on-chip 0C-85C compensation eliminates external thermistor linearization, simplifying the analog front end.
추천
HVAC Duct Pressure Transmitter
Building-automation HVAC duct-pressure monitoring benefits from the MPXM2202AS because 0-200 kPa covers typical duct static-pressure ranges while the absolute reference anchors against barometric drift. Its dry-gas compatibility suits clean supply-air ducts, and the M-PAC-5 top-port allows direct tube mounting into the duct wall. Pairing with a 4-20 mA loop transmitter such as the XTR105 completes the field-sensor chain for legacy BAS controllers.
추천
Barometric Altimeter / Weather Station
Portable altimeters and weather stations use the MPXM2202AS because its 0-200 kPa absolute range covers sea-level (101.325 kPa) up to roughly 9 km altitude (below 30 kPa). The 0.2 mV/kPa sensitivity provides 0.5 m altitude resolution after 12-bit ADC conversion, sufficient for hiking and amateur weather-logging applications. Battery-powered systems should duty-cycle the 10 V excitation via a boost regulator to extend runtime.
추천
Industrial Process Pressure Monitor
Industrial process-control loops in the 0-200 kPa range - including filter status monitoring, vacuum-line sensing, and cleanroom pressure verification - leverage the MPXM2202AS for its long-term silicon-diaphragm stability and on-chip temperature compensation. The 0-40 mV analog output interfaces directly to legacy 0-10 V PLC analog input modules via a single op-amp gain stage. The M-PAC-5 top-port accepts standard 2.97 mm tubing for pneumatic panel integration.
추천
Pneumatic System Leak Testing
Pneumatic-system leak-test fixtures use the MPXM2202AS to monitor pressure decay in a sealed manifold between 0-200 kPa. Its absolute reference gives a stable baseline for comparison, and the 10 V excitation is supplied from the test fixture's existing high-voltage rail. The 5-pin M-PAC package handles manual insertion on the test fixture PCB, and the top port accepts the pneumatic coupling directly without additional fittings.
추천
Patient Monitoring / Ventilator Side Stream
Patient monitoring and ventilator side-stream pressure measurement at low flows uses the MPXM2202AS for its calibrated mV/kPa response and clean-gas compatibility. The 0-40 mV output is amplified by an instrumentation amp before being sampled by a 1 kSPS ADC, capturing breath waveform details down to 0.1 kPa resolution. The on-chip compensation reduces the calibration burden during ventilator QA cycles.
추천
Gas Chromatograph Carrier Pressure Sense
Benchtop gas chromatographs use the MPXM2202AS to monitor carrier-gas line pressure up to 200 kPa during sample injection. Its analog mV output feeds a 24-bit sigma-delta ADC that captures both static pressure and short transients during valve actuation. The dry-gas-only media specification aligns with helium, hydrogen, and nitrogen carriers used in GC workflows.

주요 차별점
- Absolute pressure reference sealed inside the M-PAC module (vs MPXM2202GS)
- Wider 200 kPa range vs 100 kPa alternatives (vs MPXM2102A)
- Mature, broadly documented M-PAC-5 footprint (vs MPXM2202A (axial port variant))
설계 노트
The MPXM2202AS output is a differential mV-level signal on pins 2 and 4; route these traces as a guarded pair on inner PCB layers to reject common-mode noise. Keep traces shorter than 50 mm and place the instrumentation amplifier within 25 mm of the sensor to avoid picking up 50/60 Hz pickup. Twisted-pair cabling from the sensor to a remote amplifier is acceptable, but add a 10 nF bypass cap at the amplifier inputs.
Apply the 10 V excitation through a low-noise LDO such as the TPS7A4701 rather than directly from a switching converter. Bridge self-heating from ripple current shifts the zero-pressure offset; using an LDO with <5 uVrms output noise limits the drift contribution to under 0.01%FS. Estimate: a 5 mA excitation current and 10 V supply produces 50 mW dissipation at the bridge, well within thermal limits.
Despite on-chip 0C-85C temperature compensation, do not place the MPXM2202AS adjacent to power components. A 10C local temperature rise shifts the zero offset by up to 0.5%FS even with compensation. Mount the sensor on an isothermal copper pour separated from the rest of the board, and avoid forced-air heating from adjacent regulators.
Do not expose the MPXM2202AS to liquids or corrosive media - the silicon die is exposed to the gas through the top port. For water or fuel sensing, fit a media-isolated diaphragm in the pneumatic line. Also avoid miswiring pins 1 and 3 (excitation) - reversed polarity produces negative output that saturates downstream amplifiers without indicating a fault to software.
규정 준수 정보
Compliance flags not directly confirmed in the verified web data snippets. The NXP product page does not display the green-compliance badge in the retrieved excerpt, so RoHS/REACH status is set to 'unknown' pending direct datasheet verification. AEC-Q100 is not applicable because this is a sensor module, not an automotive-grade IC line.
