MPX2200GP 概述
A piezoresistive pressure sensor is a MEMS device in which diffused strain gauges on a silicon diaphragm change resistance when the diaphragm deflects under applied pressure, producing a differential output that scales linearly with pressure. Within the broader signal-chain taxonomy, MPX2200GP sits in the sensor front-end layer above raw signal conditioning and below the microcontroller ADC; it is a passive analog transducer (not an active pressure IC like a digital-output barometer) and therefore requires an external precision op-amp such as an INA122 or AD620 instrumentation amplifier to scale its millivolt-level output to the 0-5 V or 4-20 mA range used by most ADCs and PLCs.
Key features include 0 mV to 40 mV typical full-scale span (10 V excitation), piezoresistive silicon diaphragm with on-chip thin-film resistor network, laser-trimmed offset and span calibration for tight part-to-part repeatability, 0.19 inch (4.93 mm) tube port for pneumatic connection, vented-gauge reference (atmospheric backside), and a robust 4-SIP unibody package with integral port. The part is specified for 0 to 200 kPa (0 to 29.01 PSI) operating pressure and is compatible with both DC constant-voltage (10 V typical) and constant-current excitation schemes.
Typical applications include industrial pneumatic controls, HVAC air-flow monitoring, medical respiratory instruments (spirometers, ventilators), consumer air-pressure gauges, altimeters and barometric instrumentation, and process-control analog front ends. The vented-gauge reference makes it well suited to applications where the absolute atmospheric pressure on the reference side must be subtracted from the measured pressure.
When designing with the MPX2200GP, plan the signal chain carefully: the differential output is ratiometric to the excitation supply, so a clean, low-noise 10 V reference (such as the REF01 or REF02) is required to avoid drift in the scaled reading. Place the instrumentation amplifier within 50 mm of the sensor to minimize common-mode noise pickup, and add ESD protection at the pneumatic port if the media is conductive or wet.

典型应用
MPX2200GP 适用于 6 应用s: Industrial Pneumatic Pressure Monitoring, Medical Spirometer and Respiratory Monitoring, HVAC Air-Flow and Duct Pressure Sensing, Consumer and Handheld Barometric Altimeters, Process-Control Analog Front End, Pneumatic Gauge and Calibration Test Benches.
Industrial Pneumatic Pressure Monitoring
The MPX2200GP's 0 to 200 kPa vented-gauge range covers the typical 0 to 30 PSI operating window of industrial air lines and pneumatic actuators, making it a direct fit for shop-floor pressure transmitters. According to the ST datasheet, the 40 mV full-scale span at 10 V excitation pairs cleanly with an INA122 instrumentation amplifier to deliver 0 to 5 V or 4 to 20 mA industrial outputs. The 4-SIP tube port accepts standard 4.93 mm push-on fittings for direct integration into regulators and filter housings. Unlike digital-output pressure ICs, the ratiometric analog output lets the host PLC compute a true differential against barometric pressure without firmware linearization.
推荐
Medical Spirometer and Respiratory Monitoring
The MPX2200GP's 200 kPa range safely covers the inspiratory and expiratory pressures of spirometers, ventilators, and CPAP monitors, while its linear millivolt output permits analog safety-trip circuitry independent of the digital MCU. The vented-gauge reference automatically subtracts ambient barometric pressure, which is useful in portable respiratory devices where atmospheric correction is required. Pairs with the AD620 instrumentation amplifier for low-noise, low-drift signal conditioning, and the REF01 for excitation. The 4-SIP port accepts standard medical-tubing adapters, and the on-chip temperature compensation keeps readings stable across body-temperature excursions.
推荐
HVAC Air-Flow and Duct Pressure Sensing
The MPX2200GP vented-gauge construction lets HVAC controllers measure differential pressure across filters, fans, and ducts while automatically cancelling barometric weather effects. Its 200 kPa range maps conveniently to the 0 to 30 PSI outputs common in commercial air-handling units, and the linear 40 mV span simplifies ADC scaling and onboard calibration. Pairs well with the INA128 instrumentation amplifier for fan-filter diagnostic loops, and the PIC18F4550 microcontroller for USB-connected building-automation gateways. The 4-SIP tube port can be plumbed directly to pitot-tube pickups using standard pneumatic fittings.
推荐
Consumer and Handheld Barometric Altimeters
The MPX2200GP can serve as the analog front-end for low-cost altimeters and weather-station barometric displays where a vented-gauge reference naturally subtracts ambient pressure to isolate altitude-related trends over short timescales. Its 40 mV span drives a low-power op-amp like the LT1012 followed by a 12-bit ADC for digital readout. The 4-SIP package is rugged enough for handheld enclosures, and the on-chip temperature compensation reduces software correction overhead in the host microcontroller.
推荐
Process-Control Analog Front End
The MPX2200GP is widely used as a low-cost analog pressure input stage for PLCs and SCADA modules where its millivolt-level differential output is scaled by an INA128 to a 0 to 10 V or 4 to 20 mA loop-powered output. The vented-gauge reference removes the need for explicit barometric compensation in plants where ambient pressure changes are negligible. Built-in laser-trimmed calibration reduces per-board calibration time to a single two-point trim against a precision pressure source, lowering production cost for OEM process-control equipment.
推荐
Pneumatic Gauge and Calibration Test Benches
The MPX2200GP's 0 to 200 kPa range and 4-SIP test port make it a convenient secondary-standard pressure transducer for calibration benches that verify gauges, regulators, and switches. The linear millivolt output maps directly to a digital multimeter or scope readout for visual verification, while the on-chip temperature compensation reduces warm-up drift during long calibration sessions. Pairs with the AD584 precision reference for excitation and the AD620 instrumentation amplifier for a calibrated analog readout.

设计说明
Excite the MPX2200GP bridge with a clean 10 V DC reference; the output span scales ratiometrically with Vexc, so any supply noise couples directly into the reading. Use a REF01 or REF02 reference rather than the 5 V logic rail; offset trim on a precision op-amp stage compensates for part-to-part tolerance. Estimated: worst-case bridge current at 10 V through ~4.7 kohm input impedance is ~2.1 mA, well within self-heating limits.
Place the instrumentation amplifier within 50 mm of the sensor pins to minimize common-mode noise pickup on long analog traces. Use a 4-wire (Kelvin) excitation path on the PCB to drop the IR drop on shared ground traces, and add a first-order RC low-pass filter (10 Hz cutoff) at the amplifier output to attenuate mechanical vibration noise in pneumatic lines.
Although the MPX2200GP is on-chip temperature compensated, the bridge self-heats ~7 mW at 10 V excitation. In a sealed enclosure, derate the surrounding components 1.5x and allow airflow past the 4-SIP package. For extreme-temperature applications (below -20 degC or above +85 degC), verify offset drift against the ST datasheet and apply a software trim if needed.
Do not block the gauge-vent port on the underside of the 4-SIP package; the vented-gauge reference requires atmospheric access for proper operation. Sealing the vent will turn the part into an unintended absolute-pressure reference and corrupt every reading. For wet media or conductive gases, add an inline hydrophobic membrane filter to protect the port from contamination.
Route excitation and signal pairs as differential pairs with a continuous ground plane beneath them, and keep digital traces (MCU, ADC clock) at least 5 mm away from the analog signal path. Place a 100 nF ceramic decoupling cap directly at the Vexc pin to shunt high-frequency noise, and add a 10 uF tantalum bulk cap near the reference source. The 4-SIP pin pitch is generous; use a star-ground topology to avoid ground loops between the sensor, amplifier, and ADC.
