MPX2202AP 概述
An absolute pressure sensor is a transducer that measures pressure relative to a sealed vacuum reference inside the die, rather than to ambient atmospheric pressure. The category hierarchy is: pressure sensor -> transducer -> sensor -> electronic component. Within NXP's MPX series, the MPX2202AP is the absolute-pressure variant, distinct from gauge (MPX2202GP) and differential (MPX2202DP) versions in the same family. The on-chip thin-film resistor network and laser-trimmed calibration provide factory-set span and offset correction, while integrated temperature compensation keeps the output stable across the operating temperature range.
Key features include a 0 mV to 40 mV full-scale output (40 mV span at 10 V excitation), ±0.25% typical linearity, ±1.0% maximum pressure hysteresis, and on-chip temperature compensation from 0 °C to +85 °C. The 4-SIP top-port package simplifies tube/port integration, and the piezoresistive bridge delivers a ratiometric output proportional to supply voltage, which simplifies system-level analog-to-digital conversion.
Typical applications include medical infusion pumps, blood-pressure monitors, industrial process control, HVAC transmitters, altimeters, barometers, and level measurement. The 200 kPa range comfortably covers physiological pressure ranges as well as low-pressure industrial processes.
When designing with the MPX2202AP, note that the output is ratiometric: it scales linearly with the excitation voltage, so a stable, low-noise 10 V reference is required to maintain absolute pressure accuracy. Add a low-offset differential amplifier downstream for signal conditioning, and provide adequate PCB thermal management to keep the die within the calibrated temperature window.

典型应用
MPX2202AP 适用于 6 应用s: Medical Infusion Pumps & Blood Pressure Monitoring, Industrial Process Control & Pneumatic Systems, HVAC Pressure Transmitters & Air-Flow Measurement, Barometric Altimeters & Weather Stations, Liquid Level Measurement in Sealed Tanks, Portable Handheld Diagnostic Equipment.
Medical Infusion Pumps & Blood Pressure Monitoring
The MPX2202AP's 0-200 kPa absolute range covers physiological pressures required for invasive blood-pressure monitoring, infusion pump line pressure, and respiratory equipment. Its 0-40 mV analog output, when paired with a low-noise instrumentation amplifier (e.g., INA128), produces a calibrated voltage proportional to arterial or venous pressure for ADC sampling. The on-chip temperature compensation from 0-85 °C eliminates the need for external thermistor linearization, simplifying medical-device BOMs. The 4-SIP axial port accepts standard 4.93 mm tubing used in clinical fluid paths. With ±0.25% typical linearity and ±1.0% hysteresis, the sensor meets the precision needs of patient-monitoring equipment while keeping the signal chain compact.
推荐
Industrial Process Control & Pneumatic Systems
In factory automation, the MPX2202AP measures compressed-air line pressure, hydraulic pressures up to 200 kPa, and tank/vessel pressures in process-control loops. The absolute reference makes it suitable for sealed systems where barometric drift must be eliminated. The 4-SIP top-port package simplifies integration into manifolds and inline fittings. Ratiometric output scales linearly with the 10 V excitation, so the same sensor can be recalibrated for different supply rails by software scaling. Compared to switch-type pressure sensors, the analog mV output enables continuous proportional control rather than binary trip points - critical for closed-loop pressure regulation.
推荐
HVAC Pressure Transmitters & Air-Flow Measurement
The MPX2202AP functions as the pressure-sensing element in HVAC duct-pressure transmitters and cleanroom pressure-differential monitors. The 0-200 kPa absolute range covers typical duct static pressures (-500 to +2500 Pa is below this range, so the MPX2202AP suits higher-pressure refrigeration and pneumatic-control applications). Its piezoresistive bridge delivers fast response suitable for dynamic pressure fluctuations in compressor cycling. On-chip temperature compensation reduces recalibration cycles in field-installed HVAC equipment. Combined with a microcontroller's ADC, the MPX2202AP enables low-cost transmitter designs that meet commercial-building automation standards.
推荐
Barometric Altimeters & Weather Stations
The MPX2202AP's absolute pressure reference (sealed vacuum) is ideal for barometric altimeters used in handheld GPS devices, drones, and amateur weather stations. The 0-200 kPa range covers sea level (~101 kPa) through high-altitude measurements (>85 kPa at 1500 m), with the linear 0-40 mV output enabling straightforward altitude calculation via the international barometric formula. The on-chip temperature compensation keeps altitude readings stable across diurnal weather temperature swings. The 4-SIP top-port package vents to the ambient via the integrated tube port, while the internal die reference remains vacuum-sealed. For best results, pair with a 24-bit sigma-delta ADC for high-altitude resolution.
推荐
Liquid Level Measurement in Sealed Tanks
In sealed-tank liquid-level measurement, the MPX2202AP measures the head pressure of the liquid column to infer fill level. The 200 kPa range corresponds to approximately 20 m of water column, covering most industrial and chemical-process tanks. The absolute reference is essential here because the tank headspace may be pressurized or under vacuum - a gauge sensor would misinterpret the headspace pressure as a level change. The 4-SIP top-port tube connection allows direct plumbing into the tank's top fitting. With ±0.25% linearity, the sensor delivers reliable level readings for inventory management and overfill prevention.
推荐
Portable Handheld Diagnostic Equipment
Battery-powered diagnostic tools benefit from the MPX2202AP's ratiometric output, which scales with supply voltage and enables simple calibration across varying battery levels. The 10 V excitation can be derived from a boost converter or directly from a regulated rail in the handheld device. The 4-SIP package's small footprint and tube port simplify ergonomic integration into probe-style instruments. Combined with a microcontroller and Bluetooth module, the sensor forms the core of portable pressure-test equipment for HVAC technicians, plumbers, and field-service engineers who need accurate readings in a compact form factor.

- On-chip temperature compensation 0-85 °C （对比 Generic uncompensated bridge sensors)
设计说明
The MPX2202AP is a ratiometric bridge sensor requiring a stable, low-noise 10 V excitation supply. Use a precision reference such as the REF02 (10 V ±0.3%) or a low-dropout regulator with low output noise rather than a switching converter, which would inject ripple into the pressure reading. Estimated: at 6 mA excitation current and 10 V supply, total bridge power is 60 mW. Add a 10 µF decoupling capacitor at the supply pin and a 0.1 µF ceramic bypass close to the IC to filter high-frequency noise.
The 0-40 mV output is too small to drive an ADC directly. Use a low-offset, low-noise instrumentation amplifier such as the INA128 (gain set to 100 gives 0-4 V output) or INA125 (which provides integrated bridge excitation). Estimated: with INA128 gain = 100, the 40 mV span maps to 4 V at full scale, comfortably driving a 5 V ADC reference. Route the bridge differential outputs as a twisted pair or guard-trace pair to reject common-mode noise, especially in noisy industrial environments.
While the MPX2202AP has on-chip temperature compensation from 0-85 °C, the sensor body itself should be thermally anchored to the system chassis or PCB ground plane to avoid self-heating drift. Estimated: with 60 mW bridge dissipation in the 4-SIP package, junction temperature rise is modest (a few °C). For best accuracy, keep the sensor away from heat-generating components such as power converters and processors; an aluminum bracket or thermal pad can improve stability in applications with large ambient temperature swings.
Do NOT apply pressure to the back side of the MPX2202AP - it is an absolute sensor with a sealed vacuum reference, and back-side pressure will damage the diaphragm or distort readings. Always plumb the 0.19" (4.93 mm) tube port to the positive pressure source. When using the gauge variant MPX2202GP, ensure the vent port (typically a separate hole or tube) remains unobstructed and open to atmosphere. For differential MPX2202DP, route both ports carefully to avoid cross-port contamination.
Mount the 4-SIP module vertically on the PCB with the tube port pointing upward (axial) or horizontally (depending on the mechanical assembly). Provide a strain-relief feature on the tube connection to avoid mechanical stress on the sensor body. Estimated: typical PCB footprint for the 4-SIP is 2.54 mm (0.1") pin pitch; verify Case 344B-01 mechanical dimensions in the datasheet before laying out holes. Add a keep-out zone around the package body to allow for the tube fitting and any sealing O-ring.
