MPXV2202GP 개요
A piezoresistive pressure sensor is a MEMS device in which a diaphragm etched into a silicon substrate flexes under applied pressure, changing the resistance of four implanted piezoresistors arranged in a Wheatstone bridge; the bridge produces a differential output voltage proportional to pressure. Piezoresistive sensors belong to the broader category of pressure transducers, which in turn are a sub-family of sensors alongside temperature, motion, and flow sensors. Pressure sensors are foundational in industrial process control, medical instrumentation, HVAC, and automotive systems, where they translate mechanical pressure into precision electrical signals that a microcontroller or instrumentation amplifier can digitize.
Key features of the MPXV2202GP include 0 mV to 40 mV output span at 10 V excitation, 0.2 mV/V nominal sensitivity, on-chip temperature compensation across 0 to 85 C, and a vented gauge reference that lets the part measure pressure relative to atmosphere. The integrated Wheatstone bridge plus laser-trimmed resistors deliver calibrated accuracy without external compensation components. The SOP-8 case style, also referred to as SO-8 or SO8 with small-outline plastic body measuring 12.06 mm x 12.06 mm x 8.38 mm with 2.54 mm pitch, supports surface-mount assembly and provides a robust mechanical port that simplifies pneumatic connection.
Typical applications include medical respiratory monitors, HVAC blower and filter monitoring, industrial pneumatic controls, and low-pressure process instrumentation. Designers use it where a calibrated, linear, ratiometric analog output is preferred over digital sensor ICs. The device is drop-in compatible with other members of the MPX2202/MPXV2202 family, simplifying board-level reuse across product variants.
When designing with this part, ensure a stable low-noise 10 V excitation source and a high-gain instrumentation amplifier (such as INA128 or AD620) on the output, because the native 40 mV full-scale signal must be amplified to interface with typical 0 to 5 V ADC inputs. A small RC low-pass filter (typically 1 kohm plus 0.01 uF) at the output limits EMI and aliasing before digitization.

Medical Respiratory Monitor
The MPXV2202GP's 0 to 200 kPa gauge pressure range covers the full spectrum of clinical airway pressures used in ventilator and respiratory-monitoring circuits, while its on-chip temperature compensation maintains calibration accuracy across patient body-temperature variations. Its native 40 mV differential bridge output drives a high-gain instrumentation amplifier (such as INA128 or AD620) to deliver a 0 V to 5 V signal for an ADC front-end, and its vented-gauge port references pressure to ambient, matching clinical measurement conventions. The SO8 side-port package simplifies sterile single-patient circuit integration.

HVAC Blower and Filter Monitor
Building-automation HVAC systems use the MPXV2202GP to measure duct static pressure across blower fans and filter banks, where its 0 to 200 kPa (29 psi) range comfortably exceeds typical 0 to 10 kPa duct pressures with headroom for transient spikes. The vented-gauge configuration compensates for ambient atmospheric changes, improving reading accuracy in rooftop or unconditioned-space installations. Its calibrated linear 0.2 mV/V output lets a controller ADC sample directly through a differential amplifier, simplifying the analog front-end in variable-air-volume (VAV) box controls.
추천
Industrial Pneumatic Pressure Switch
Industrial pneumatic systems use the MPXV2202GP to monitor shop-air pressures up to 200 kPa, replacing mechanical pressure switches that suffer from drift and contact wear. The piezoresistive sensor's solid-state construction delivers infinite resolution and a stable 0.2 mV/V ratiometric output that can be compared against an external setpoint using a comparator such as LM393. The SO8 gull-wing package withstands typical factory floor vibration and the 0.13 inch side port accepts standard pneumatic tubing directly.
추천
Blood Pressure Monitor Front-End
The MPXV2202GP is well-suited to electronic sphygmomanometer designs where cuff pressures up to 200 kPa must be measured with linearity better than +/-1 percent. Its on-chip temperature compensation eliminates the need for discrete thermistor networks around the bridge, while its calibrated output couples directly to a low-noise analog front-end. Designers pair it with an instrumentation amplifier (AD620), a 16-bit delta-sigma ADC, and a microcontroller that derives systolic, diastolic, and mean arterial pressure using oscillometric algorithms.
추천
Coffee Machine Pressure Profiling
Espresso machine pressure-profiling controllers use the MPXV2202GP to measure brew-head pressures in the 0 to 12 bar range (up to 1200 kPa, so designers typically select a lower-range variant or scale the analog front-end with attenuation). The 0 to 200 kPa native range fits low-pressure steam and pump-pressure monitoring in consumer machines. Its calibrated analog output integrates cleanly with espresso controller boards that already use instrumentation amplifiers, and the SO8 surface-mount package suits compact machine electronics enclosures.
추천
Liquid Level Detection via Bubbler System
In tank-level measurement, the MPXV2202GP forms the heart of a bubbler system where a low-flow pump feeds air through a dip tube and the resulting back-pressure, equal to the hydrostatic head of liquid in the tank, is read by the sensor. With 0 to 200 kPa range, this method handles tanks up to roughly 20 meters deep. The vented-gauge configuration automatically compensates for barometric pressure changes, and the SO8 package fits into a weatherproof transmitter housing for outdoor tank installations.
추천
Weather Station Barometric Sensor
Although the MPXV2202GP is a gauge sensor, designers can repurpose it for barometric weather measurement by sealing the side port and exposing only the package back-side vent, providing a stable reference to local atmospheric pressure variations. Its calibrated 0.2 mV/V output and on-chip temperature compensation yield resolution sufficient for hobbyist weather stations tracking millibar-scale pressure changes. The SO8 package and surface-mount construction enable compact PCB integration with ESP32 or STM32 weather logger boards.

설계 노트
Provide a low-noise, well-regulated 10 V excitation source for the MPXV2202GP bridge. Because the output is ratiometric at 0.2 mV/V, any supply ripple couples directly into the sensor output as common-mode plus differential noise. A linear regulator such as LP2985 or LT3042 followed by an RC low-pass filter (10 ohm plus 10 uF) gives clean excitation. Estimated: the bridge draws approximately 1 mA quiescent, so a 50 mA-rated regulator leaves comfortable margin.
The MPXV2202GP native output is 0 to 40 mV differential, which is too small to drive a 0 to 5 V ADC input without amplification. Use an instrumentation amplifier (INA128, AD620, or INA333) with gain of about 100 to deliver a 0 V to 4 V single-ended signal. Place the INA within 50 mm of the sensor pins to minimize noise pickup, and add a 1 kohm plus 0.01 uF RC low-pass filter at the amplifier output to limit ADC aliasing. Estimated: with 0.2 mV/V sensitivity and 10 V excitation, full-scale 200 kPa yields 40 mV differential.
Route the four bridge-excitation traces (Vs, GND, Vout+, Vout-) as parallel pairs in a tight differential-routing pattern to reject common-mode noise. Keep digital lines (PCBs from microcontroller, ADC clock, switching regulators) at least 5 mm away from the sensor traces to avoid coupling. The SO8 gull-wing pads should be soldered with no-clean paste; avoid hand-soldering the side port because thermal stress can distort the integrated pneumatic fitting.
Do not apply pressure beyond 200 kPa to the MPXV2202GP - the silicon diaphragm will mechanically bottom out and permanently distort the bridge calibration. Add a mechanical pressure-snubber or inline restrictor upstream if the source is a pump or compressor that could transiently exceed the range. Also avoid blocking the vent path on the back of the package; a clogged vent causes the gauge reading to drift with ambient barometric pressure changes.
