MPX2200AP - 200 kPa Absolute Pressure Sensor 4-SIP | NXP
MPN： MPX2200AP ✗ 停產MPX2200AP 概覽
A piezoresistive pressure sensor is a MEMS device in which four silicon piezoresistors arranged in a Wheatstone bridge on a silicon diaphragm change value as the diaphragm flexes under applied pressure. The MPX2200AP's transducers are on-chip temperature compensated between 0C and 85C, eliminating external compensation networks and simplifying signal conditioning. The device is part of the broader sensor category hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor -> electronic component, and integrates analog signal conditioning at the die rather than as an external circuit.
Key features include 0 mV to 40 mV full-scale output, 0.2 mV/V typical sensitivity (FS span / excitation / full-scale = 40 mV / 10 V / 200 kPa), 0C to 85C compensated temperature range, and absolute pressure sensing with internal vacuum reference. The 4-SIP package provides a single axial pressure port and through-hole mounting suitable for industrial and medical pressure measurement. These specifications make it a workhorse for legacy designs in industrial process control, medical instrumentation, and pneumatic systems where calibrated millivolt outputs feed external instrumentation amplifiers and ADCs.
Typical applications include barometric pressure measurement, medical respiratory monitoring, industrial process pressure sensing, HVAC duct pressure, and altitude measurement. The millivolt-level output is typically amplified by an external instrumentation amplifier such as the INA128 or AD620 before ADC conversion. The device is frequently used in motor drive and control, robotics, and test and measurement systems requiring reliable absolute pressure readings.
When designing with the MPX2200AP, plan for a high-gain low-noise instrumentation amplifier front end and a stable 10 V excitation supply. The 4-SIP module requires through-hole PCB mounting and axial pressure port connection - check port tubing interface (4.93 mm / 0.19 inch male tube). The datasheet estimates an end-of-life date of 2025, so for new designs consider the MPX2202AP successor.

典型應用
MPX2200AP 適用於 6 應用s: Barometric Pressure Measurement, Medical Respiratory Monitoring, Industrial Process Pressure Sensing, HVAC Duct Pressure Monitoring, Altitude Measurement and Avionics, Test and Measurement Instrumentation.
Barometric Pressure Measurement
The MPX2200AP's 200 kPa absolute pressure range spans the typical barometric pressure window (roughly 80 kPa to 105 kPa at sea level), making it suitable for weather stations and altimeters. Its millivolt-bridge output requires an external instrumentation amplifier (AD620 or INA128) before ADC input, and the 0C to 85C compensated range covers outdoor environmental monitoring. The 4-SIP axial port accepts 4.93 mm tubing for sealed air reference.

Medical Respiratory Monitoring
The MPX2200AP provides calibrated absolute pressure output for spirometers, ventilators, and CPAP machines measuring patient airflow and lung pressure. Its on-chip temperature compensation between 0C and 85C covers clinical environments without additional thermal drift correction. The millivolt-level output integrates with medical-grade instrumentation amplifiers and isolation barriers for patient-connected equipment meeting IEC 60601 requirements.

Industrial Process Pressure Sensing
The MPX2200AP's 200 kPa range covers low-pressure industrial processes including pneumatic systems, filter pressure drop monitoring, and tank level sensing via pressure transduction. Its 0.2 mV/V sensitivity and 10 V excitation deliver reliable millivolt output for PLC analog input modules after signal conditioning. The through-hole 4-SIP module with axial port simplifies field wiring in industrial enclosures and control panels.
推薦
HVAC Duct Pressure Monitoring
The MPX2200AP measures duct static pressure in variable air volume (VAV) systems, filter status monitoring, and air handler fan tracking. Its 200 kPa absolute range covers typical HVAC duct pressures (0 to 2 kPa typical operating, with headroom for transients). The millivolt bridge output interfaces with HVAC controller analog inputs via instrumentation amplifiers, providing differential pressure for airflow calculations.

Altitude Measurement and Avionics
The MPX2200AP's absolute pressure sensing enables altitude determination via the international standard atmosphere model, suiting drones, UAVs, and recreational avionics. Its 200 kPa range covers sea-level (101.325 kPa) to high altitude (approximately 1.5 km at 85 kPa), with on-chip temperature compensation for outdoor thermal variation. The compact 4-SIP module integrates into space-constrained flight controller PCBs.

Test and Measurement Instrumentation
The MPX2200AP serves as a calibrated pressure reference in laboratory test equipment, calibration benches, and pressure comparator instruments. Its 200 kPa range and 40 mV full-scale output provide a known transfer standard for verifying other pressure instruments. The legacy Motorola/NXP heritage and stable production history make it a trusted reference in calibration laboratories and quality assurance test systems.

設計說明
The MPX2200AP millivolt-level output is highly susceptible to noise and thermal EMF. Use a low-noise instrumentation amplifier (AD620 or INA128) with shielded twisted-pair connections from the 4-SIP module to the amplifier input. Keep excitation supply stable to within 0.1% (use an LT3042 or similar low-noise LDO for the 10 V excitation). Add 100 nF decoupling capacitors at the bridge excitation pins and at the instrumentation amplifier reference pin to suppress high-frequency noise.
On-chip temperature compensation covers 0C to 85C; outside this range, apply software compensation using a co-located temperature sensor (e.g., MAX31855). Self-heating of the bridge (typically a few mW at 10 V excitation) can cause a 1-2C temperature rise that introduces drift in precision applications. Mount the 4-SIP module with thermal isolation from heat sources and allow convective airflow for stable readings.
Do not apply pressure exceeding 200 kPa absolute to the MPX2200AP - overpressure can permanently damage the silicon diaphragm. The 4-SIP module requires through-hole PCB mounting with proper mechanical support of the axial port; do not allow tube-side stress to transfer to the SIP pins. Use a 4.93 mm (0.19 inch) tube with a sealed fitting to prevent pressure leaks. Verify polarity of excitation voltage before power-up, as reverse connection can damage the bridge.
