MPX2200A Présentation
A piezoresistive pressure sensor is a transducer in which the piezoresistive effect of silicon is used to convert mechanical strain from an applied pressure into a differential resistance change; this change is then read out as a differential voltage across an integrated Wheatstone bridge. Within the broader sensor hierarchy, the MPX2200A sits at: pressure sensor -> force/pressure transducer -> MEMS sensor -> sensor IC. Because the bridge output is ratiometric to excitation voltage, the device scales naturally with supply, simplifying external ADC calibration.
Key features include a typical full-scale output of 40 mV at 10 V excitation (0.2 mV/kPa nominal sensitivity for the A-version), temperature compensation across 0 to +85 C, low off-axis sensitivity, and a single-side ported 4-SIP module with PC-pin termination for through-hole PCB mounting. The integrated unibody construction eliminates the need for external O-ring sealing in many board-mount medical and industrial applications.
The MPX2200A exploits a monolithic silicon die diffused with a piezoresistive bridge whose resistors change value under membrane deflection. On-chip laser trimming flattens the temperature curve and minimizes zero-pressure offset, so designers receive a near-calibrated device that requires only gain-setting on the signal-conditioning front end. The 4-SIP package isolates the pressure port from the PCB, allowing conformal coating of surrounding circuitry.
Typical applications include medical non-invasive blood pressure monitoring, industrial process pressure transmitters, altimeters and barometric references, HVAC pressure switches, and liquid level sensing via hydrostatic head. Industrial and medical instrumentation are dominant end uses because the temperature compensation and mV-level analog output simplify interface to 16-bit ADCs.
Designers must provide a clean, low-noise 10 V excitation reference (the output is ratiometric), typically using a low-dropout regulator or a reference buffer. Decoupling caps and guarding on the bridge outputs reduce susceptibility to supply ripple and EMI pickup when cabling to distant signal-conditioning boards.

Applications typiques
MPX2200A convient pour 7 applications: Non-Invasive Blood Pressure Monitors, Industrial Process Pressure Transmitters, Barometric Altimeters and Weather Stations, HVAC Pressure Switches and Duct Sensors, Hydrostatic Liquid-Level Sensing, Respiratory and Sleep Apnea Equipment, Automotive Manifold Pressure Reference Designs.
Non-Invasive Blood Pressure Monitors
The MPX2200A's 0 to 200 kPa range matches cuff pressures used in non-invasive blood pressure (NIBP) measurement, while its on-chip temperature compensation across 0 to +85 C eliminates lookup-table calibration in the clinical environment. Its 40 mV full-scale span at 10 V excitation gives 0.2 mV/kPa sensitivity, which after a single-stage INA128 instrumentation amplifier conveniently fills a 16-bit ADC with one LSB per few hundred Pa. The unibody 4-SIP package is solvent-cleanable for medical device sterilization. Unlike gel-coupled invasive transducers, this part directly addresses pneumatic cuff lines, simplifying the patient-side hardware.

Industrial Process Pressure Transmitters
In 4-20 mA loop-powered process transmitters, the MPX2200A provides the front-end pressure measurement with a stable 0 to 200 kPa absolute span and 116 PSI overpressure margin. Its ratiometric Wheatstone bridge output aligns with loop transmitters whose 10 V excitation references are already ratiometric to the ADC, so software calibration compensates supply drift automatically. The 0.2 mV/kPa sensitivity is sufficient to resolve sub-100 Pa changes after modest gain, supporting flow-element and tank-level applications. The 4-SIP PC-pin termination survives vibration and thermal-cycling in field-mounted instrumentation.
Recommandé
Barometric Altimeters and Weather Stations
Although its 0 to 200 kPa absolute range covers sea level plus substantial altitude headroom, the MPX2200A is best suited to weather-barometer rather than aviation-altitude applications. Its 0.2 mV/kPa sensitivity resolves 10 Pa altitude bins after a 100x gain stage, which corresponds to roughly 1 meter of height - useful for amateur weather stations and HVAC differential reference. On-chip temperature compensation from 0 to +85 C keeps barometric readings stable through diurnal swings without firmware compensation. Compared with digital barometric ICs like BMP280, the MPX2200A outputs a clean analog mV signal that pairs naturally with sigma-delta ADCs in mixed-signal logger designs.
Recommandé
HVAC Pressure Switches and Duct Sensors
In HVAC duct-pressure and filter-loading sensors, the MPX2200A delivers reliable 0 to 200 kPa absolute readings with a 4-SIP form factor that mounts inside standard pressure taps. Its 116 PSI maximum overpressure withstands transient spikes during fan startups and damper closures, preventing field failures that plague less robust sensors. The 0.2 mV/kPa nominal sensitivity enables direct microcontroller ADC sampling without a dedicated instrumentation amplifier when 8-bit resolution suffices. Compared with bare MEMS die, the ruggedized SIP unibody resists condensation and particulate in commercial HVAC ducts.
Recommandé
Hydrostatic Liquid-Level Sensing
When mounted at the bottom of a tank, the MPX2200A measures hydrostatic head from the liquid column above; for water, every 1 kPa corresponds to about 102 mm of depth. Its 0 to 200 kPa span therefore covers liquid columns of roughly 20 meters before re-ranging, satisfying most potable-water and chemical-tank applications. The on-chip temperature compensation reduces warm-cold drift when tanks cycle through environmental changes, while the analog ratiometric output feeds directly into 4-20 mA tank-level transmitters. Compared with non-contact ultrasonic sensors, the MPX2200A delivers a calibrated analog signal that does not require foam or surface-wave compensation.
Recommandé
Respiratory and Sleep Apnea Equipment
The MPX2200A is commonly used in CPAP and BiPAP machines for proximal airway pressure sensing, where its 0 to 200 kPa absolute range comfortably covers therapeutic pressures plus transient peaks. Its low noise floor (well below 1 kPa RMS equivalent after amplification) enables detection of subtle flow-limitation events important in sleep medicine. The 4-SIP unibody isolates electronics from humidified gas streams, and the ratiometric mV output simplifies design with battery-powered 12-bit ADCs. Compared with disposable inline flow sensors, the MPX2200A delivers hospital-grade accuracy suitable for reusable ventilator manifolds.
Recommandé
Automotive Manifold Pressure Reference Designs
Although not AEC-Q100 qualified, the MPX2200A's 0 to 200 kPa range and -40 to +125 C operating temperature make it a reference design starting point for non-safety automotive pressure modules such as cabin HVAC or fuel-pressure monitoring. Its 800 kPa overpressure rating tolerates pressure spikes during ignition events, and its rugged 4-SIP package supports conformal coating in engine bay environments. The analog mV output pairs with classic ECU front-ends and aftermarket standalone ECUs. For safety-critical applications, designers should migrate to AEC-Q100 qualified successors such as MPX5700 series.

Notes de conception
Bridge excitation must be a low-noise, low-drift 10 V reference; the MPX2200A is ratiometric, so the same rail should drive the ADC reference to cancel drift. A REF02 or ADR01 typically meets this need. Add 100 nF + 10 uF decoupling right at the sensor's Vex pins to keep switch-mode ripple from coupling into the 0.2 mV/kPa output. The bridge draws only a few mA so an LDO is usually acceptable in place of a discrete reference.
Use a true instrumentation amplifier (INA128, AD620, or MAX4462) configured for ~100x gain to lift the 40 mV full-scale span to 4 V for a 5 V ADC. Route bridge outputs as a twisted pair or guarded differential trace and keep them away from switching converters and AC mains runs. Add 10 nF common-mode capacitors at the in-amp inputs to suppress RF pickup. Avoid single-ended amplification of either side alone - the bridge is differential for a reason, and common-mode errors will dominate otherwise.
Do not connect the gas or liquid media to a portless device: the MPX2200A's no-port (A) variant exposes the die to whatever side of the housing is open, so contamination can shift calibration. If your media is wet, choose MPX2200AP (axial port) with appropriate tubing and an inline hydrophobic filter. Ensure the silicone gel isolation does not see pressures beyond the 800 kPa overpressure rating or the die can rupture. Always store the device in its conductive tray until final assembly to prevent ESD damage at the piezoresistive junctions.
