MPX2202GP Visão geral
A piezoresistive pressure sensor is a MEMS device in which a diaphragm with embedded strain gauges changes resistance proportionally to applied differential pressure; the MPX2202GP integrates on-chip signal conditioning and temperature compensation so the user only applies 10 V DC excitation and reads a ratiometric millivolt signal. Within the broader sensor taxonomy, this part sits in the hierarchy: pressure sensor -> piezoresistive pressure sensor -> silicon strain-gauge sensor -> MEMS sensor -> transducer, and the 4-SIP package belongs to the through-hole SIP (Single Inline Package) family used predominantly for legacy and industrial pneumatic interfaces.
Key features include 0 mV to 40 mV full-scale output (10 V supply), 0 to 200 kPa operating range, on-chip temperature compensation and calibration, gauge (vented) reference, and linear response directly proportional to applied pressure. The integrated compensation network eliminates the need for external trim circuitry, simplifying host-microcontroller or A/D front-end designs.
The device is built on a silicon die using a diffused piezoresistive Wheatstone-bridge topology, with the four bridge resistors laser-trimmed during wafer-level test. The 4-SIP top-port housing routes incoming pressure through a tube stub to the diaphragm side of the die while the back side vents to the reference (ambient) via the package's secondary port, producing a true gauge output.
Typical applications include medical patient monitoring (blood pressure, respiratory), HVAC air-flow and duct pressure sensing, industrial pneumatic control, altimeters and barometric instruments, and consumer appliance pressure monitoring. The 4-SIP top-port geometry suits manifolds and enclosures where pressure tubing enters vertically.
A key design consideration is that the output is ratiometric with the 10 V supply: any supply noise directly couples into the output, so a low-noise, low-drift excitation regulator is required to realize the datasheet accuracy. Dry air or non-corrosive gases are the only verified media; aggressive media require factory consultation.

Aplicações típicas
MPX2202GP é adequado para 6 aplicaçãos: Medical Blood Pressure Monitors, HVAC Duct and Air-Flow Pressure Sensing, Industrial Pneumatic Control Systems, Barometric and Altitude Measurement Instruments, Consumer Appliance Pressure Monitoring, Level Measurement in Sealed Tanks.
Medical Blood Pressure Monitors
The MPX2202GP's 0 to 200 kPa (29 PSI) range and on-chip temperature compensation map directly onto non-invasive blood pressure cuff pressure sensing, while the 0 to 40 mV ratiometric output simplifies integration with the discrete or AFE instrumentation amplifier front-end common in medical patient monitors. With the 10 V excitation rail coming from a low-noise regulator, the linearity error stays within clinical-grade limits across the cuff inflation cycle. The 4-SIP top-port module provides a molded tube-fitting interface that accommodates disposable cuff tubing, and the gauge (vented) reference means the device correctly tracks atmospheric barometric changes during patient transit. Confidence in long-term stability is bolstered by NXP's automotive-grade reliability heritage and the family's documented 0-50 C calibrated range.

HVAC Duct and Air-Flow Pressure Sensing
The MPX2202GP's 0-200 kPa range and gauge (vented-to-atmosphere) topology make it a natural fit for HVAC duct static pressure, VAV (variable air volume) box differential sensing, and filter-clog detection, where pressures typically operate in the 0 to 5 kPa range but need headroom for startup transients. The 4-SIP top-port module's male tube port integrates directly with 1/8" pneumatic tubing and the through-hole PCB mounting simplifies field-replacement during service. Because the device is ratiometric, designers can use a 10 V reference rail shared across multiple sensors for consistent gain calibration across the building automation controller's A/D channels. The integrated temperature compensation yields usable accuracy across the 0-50 C operating envelope typical of commercial HVAC plenums, while the silicon piezoresistive die tolerates the dry air media found in ductwork.

Industrial Pneumatic Control Systems
For industrial pneumatic regulators, valve position feedback, and 0-200 kPa cylinder pressure telemetry, the MPX2202GP delivers a calibrated mV output that scales linearly with the supply, simplifying current-loop transmitter designs built around 4-20 mA loops. The silicon piezoresistive sensor's inherent ruggedness withstands industrial vibration profiles, and the on-chip temperature compensation eliminates the need for software-side temperature lookup tables that would otherwise consume microcontroller code space. The male 0.19" (4.93 mm) tube port drops directly into standard industrial pneumatic fittings, and the through-hole 4-SIP package is wave-solder compatible for low-cost factory assembly. Engineers can pair the device with a low-noise 24V-to-10V isolated regulator to meet industrial surge immunity standards while keeping the analog front-end isolated from ground noise.
Recomendado
Barometric and Altitude Measurement Instruments
Altimeters, weather stations, and barometric pressure instruments benefit from the MPX2202GP's stable gauge reference and ratiometric 0-40 mV output, which scales predictably with the 10 V excitation rail, allowing precise altitude calculation up to several thousand meters. Because the device is vented to atmosphere via the package's secondary port, it tracks local barometric changes naturally without requiring a separate reference tube, and the on-chip temperature compensation removes the dominant error source in field deployments exposed to morning-to-night thermal cycles. The 4-SIP top-port module packages the sensor in a rugged molded housing suitable for handheld weather instruments, and the through-hole PCB layout simplifies the mechanical integration with weather-station enclosures.

Consumer Appliance Pressure Monitoring
Washing-machine water-level sensors, dishwasher spray-arm pressure monitors, and refrigerator compressor diagnostics all benefit from the MPX2202GP's 0-200 kPa range, gauge reference, and ratiometric output that pairs easily with the appliance microcontroller's A/D converter. The on-chip temperature compensation simplifies end-of-line calibration because the device does not require firmware-based compensation tables, and the 4-SIP top-port module's tube port accepts standard appliance pneumatic tubing without adapters. Designers can share the 10 V excitation regulator across multiple pressure and flow sensors on the appliance's analog board, using just one precision reference to maintain gain accuracy across the whole system. The device's industrial heritage means it survives the humidity and vibration profiles common in white-goods environments.
Recomendado
Level Measurement in Sealed Tanks
For sealed-tank liquid-level measurement where the gas space above the liquid has its own reference pressure, the MPX2202GP can be paired with a reference tube pulled to a known ambient point, providing an effective differential reading scaled across the 0 to 200 kPa range. The 0 to 40 mV output feeds a low-cost instrumentation amplifier that drives a 4-20 mA current loop for long-cable runs to a PLC. Because the sensor is silicon-based and temperature compensated, it does not drift during long standby periods, making it suitable for chemical storage tanks where monthly-level telemetry is required. The 4-SIP top-port module's tube port accepts standard pneumatic fittings, and the through-hole PCB assembly minimizes assembly cost for instrumentation OEMs producing hundreds of units per month.

Notas de projeto
Estimated: Supply the MPX2202GP from a low-noise, low-drift 10 V reference such as the REF02 or LT1021, or a low-noise 10V LDO such as LP2980 derived from a clean 12V or 15V rail. The output is fully ratiometric with this supply: a 1 mV ripple on the 10V rail appears at the output as 4 microvolts of sensor-referred noise; a standard 7805-equivalent regulator ripple would consume the entire 0-40 mV signal-to-noise budget. Add a 10 µF bulk + 0.1 µF ceramic decoupling capacitor pair at the VCC pin.
Place the instrumentation amplifier (e.g., AD620 or INA128) within 50 mm of the sensor's output pins to avoid picking up EMI on the millivolt signal leads. Use a guard trace tied to the amplifier reference potential around the high-impedance signal traces to suppress leakage from adjacent PCB nodes. Route the 10 V excitation trace separately and away from sensitive analog paths; the gauge (vented) reference port must be unobstructed for accurate atmospheric referencing.
Do not apply pressure above the 200 kPa range or expose the device to media other than dry air or non-corrosive gases — the sensor will permanently drift or fail. Avoid sealing the gauge vent port; if the application requires sealed references, choose the MPX2202AP (absolute) variant. The 0-40 mV output is small compared to typical A/D full scales — without 50x to 100x amplification, resolution will be unusable.
