MPXV2202DP 개요
A piezoresistive pressure sensor is a MEMS device in which diffused silicon resistors change resistance when mechanical strain is applied to a diaphragm. The MPXV2202DP belongs to the pressure sensor family within the broader sensor hierarchy (sensor -> transducer -> MEMS -> semiconductor). Piezoresistive sensors differ from capacitive or resonant types by offering a simple ratiometric analog voltage output that is easy to read with any ADC, at the cost of slightly higher noise and lower absolute accuracy than capacitive alternatives. They are typically used where cost, linearity, and DC response matter more than ppm-level precision.
Key features include 0 mV to 40 mV output span over 0 to 200 kPa, 0.25% typical linearity (best-fit straight line), ±0.5% full-scale span temperature error over 0°C to 85°C, 5 kHz frequency response, and an operating temperature range of -40°C to +125°C. The sensor is differential (two ports on the same side of the package), allowing either gauge or differential measurements depending on how the ports are connected. The 8-BSOP housing has a thermal resistance suitable for direct PCB mounting in industrial environments, and the on-die compensation eliminates the need for external thermistor networks.
The device integrates a Wheatstone bridge of four piezoresistors diffused into a silicon diaphragm. When pressure is applied across the dual ports, the diaphragm flexes and unbalances the bridge, producing a differential voltage that scales linearly with applied differential pressure. The on-chip thin-film resistors perform gain and offset calibration, while proprietary temperature compensation corrects the span and offset drift across the operating range, producing a near-plug-and-play analog pressure output that interfaces directly with instrumentation amplifiers or ADC front-ends.
Typical applications include medical ventilators and respiratory monitoring, HVAC differential pressure measurement, industrial process control, analytical instruments, and tire pressure monitoring. The differential port configuration also makes the part useful in flow measurement when paired with a laminar flow element (Pitot tube or orifice plate). Its dual-port same-side form factor simplifies hose connection in medical equipment where tubing geometry is constrained.
When designing with the MPXV2202DP, note that the 40 mV full-scale span requires an instrumentation amplifier with low offset drift (such as the INA128 or AD620) to reach usable system-level resolution. Place 100 nF ceramic bypass capacitors on the supply pins and route sensor grounds in a star configuration with the amplifier ground to avoid digital noise injection. For medical applications, verify media compatibility because the datasheet only characterizes dry air operation.

Medical Ventilator and Respiratory Monitoring
The MPXV2202DP's 0-200 kPa differential range directly covers the airway pressures used in adult and pediatric mechanical ventilation (typical peak inspiratory pressures of 10-40 cmH2O extend to several kPa when circuit compliance is included). Its 40 mV full-scale output at 10 V is easily amplified by medical-grade instrumentation amplifiers such as the INA128 or AD620, which then drive a 16-bit ADC for breath-by-breath pressure waveform capture. The 5 kHz response bandwidth comfortably reproduces the fastest pressure transients in high-frequency oscillatory ventilation, while the on-chip temperature compensation holds span accuracy within ±0.5% FS across the 0-85°C range typical of clinical environments. Designers should pair the sensor with a hydrophobic filter to prevent condensate from the humidifier circuit reaching the die, since the datasheet only characterizes dry air operation. For FDA submissions, validate the media compatibility and sterilization workflow with the sensor manufacturer before locking the BOM.

HVAC Differential Pressure Measurement
In HVAC systems the MPXV2202DP measures filter pressure drop across air handling units, fan static pressure, and duct static pressure in the 0-200 kPa range typical of commercial building automation. Its dual-port differential configuration allows direct connection across a filter or fan inlet/outlet with two short pneumatic tubes, eliminating the need for a separate gauge port and reference plumbing. The 0.25% typical linearity delivers accurate filter-loading detection so that the building management system can schedule filter replacement at the right time, while the ratiometric mV output simplifies compliance with 0-10 V analog input modules common in BACnet and Modbus controllers. The -40°C to +125°C operating range covers unconditioned rooftop and mechanical-room environments without additional thermal protection.

Industrial Process Control and Pneumatic Systems
The MPXV2202DP provides accurate differential pressure sensing for industrial pneumatic systems, where compressed-air line pressures typically operate at 4-7 bar (400-700 kPa). For higher-pressure systems the sensor can monitor the pressure drop across flow-restriction elements to derive volumetric flow rate, with the ratiometric 40 mV output simplifying downstream signal conditioning. Its wide -40°C to +125°C operating envelope and surface-mount 8-BSOP package make it suitable for installation in IP65-rated field enclosures without hermetic packaging, while the laser-trimmed span and offset reduce per-unit calibration time in volume production. Industrial designers typically pair the sensor with a 4-20 mA current-loop transmitter IC such as the XTR105 to deliver noise-immune analog signals across long plant-floor cable runs.

Analytical Instruments and Lab Equipment
Laboratory analytical instruments such as gas chromatographs, mass spectrometer inlet systems, and bioreactor pressure monitoring benefit from the MPXV2202DP's low-noise piezoresistive bridge and 0-200 kPa differential range. Its 5 kHz bandwidth captures rapid pressure transients during sample injection and column switching, while the 0.25% typical linearity supports quantitative analysis workflows without per-channel calibration overhead. The dual-port configuration allows direct measurement across membrane filters in bioreactor off-gas lines, where differential pressure correlates with filter loading and foam events. Combined with a low-offset chopper-stabilized amplifier such as the LTC2050, the sensor delivers ppm-level resolution suitable for research-grade instrumentation.

Tire Pressure Monitoring Systems (TPMS)
Although most modern TPMS designs use battery-powered wireless transmitters, bench and diagnostic equipment that calibrates and tests TPMS sensors benefits from the MPXV2202DP's differential 0-200 kPa range and dual-port configuration. The sensor can apply controlled pressure to a TPMS sensor under test while monitoring the wireless response, with the 40 mV output span digitized by a 12-bit ADC for closed-loop pressure control. Its wide -40°C to +125°C operating range covers the cold-soak and high-speed-driving temperature extremes that production TPMS sensors must survive, while the surface-mount 8-BSOP package simplifies integration into automated test fixtures. The on-chip calibration reduces test station per-unit setup time compared to uncalibrated bridge sensors.

Flow Measurement with Orifice or Pitot Tube
The MPXV2202DP measures the differential pressure across a primary flow element (orifice plate, Venturi, or Pitot tube) to derive volumetric flow rate via the Bernoulli relationship. The dual same-side port configuration simplifies plumbing to the high- and low-pressure taps of the primary element, with the 0-200 kPa differential range suitable for low-velocity air and gas flow measurement in cleanroom and process applications. Its 0.25% typical linearity keeps flow calculation error within the limits of ISO 5167 orifice measurement standards, while the on-chip temperature compensation holds span accuracy across changing process temperatures. Combined with a square-root extractor IC or firmware square-root calculation, the sensor delivers an accurate flow transmitter without a separate differential-pressure transmitter module.

설계 노트
The MPXV2202DP outputs a low-level 40 mV differential signal at full scale, which is highly susceptible to common-mode noise and ground-loop interference. Use a true instrumentation amplifier (INA128, AD620) with at least 60 dB CMRR at DC to extract the differential signal cleanly. Route the sensor-to-amplifier traces as a twisted pair or shielded cable in industrial environments, and place 100 nF ceramic bypass capacitors within 5 mm of the Vs and GND pins to suppress high-frequency supply noise. For high-accuracy designs, add a low-pass filter (typically 10 Hz to 1 kHz) at the amplifier output to limit noise bandwidth before the ADC input.
While the MPXV2202DP is on-chip temperature compensated, residual temperature error of ±0.5% FS span and ±1% FS offset remains across the 0°C to 85°C operating range. For precision applications requiring better than 1% FS accuracy over temperature, perform a two-point calibration in firmware at +25°C and either 0°C or +85°C, then apply a multi-term polynomial correction. The 8-BSOP package has a thermal resistance suitable for direct PCB mounting without heatsinking because the sensor draws less than 10 mA from the 10 V supply. Avoid placing heat-generating components (power inductors, LDOs) within 10 mm of the sensor to minimize thermal coupling.
Do not apply pressure beyond the 200 kPa full-scale range without derating for temperature, as the silicon diaphragm can rupture at approximately 2x overpressure and permanently damage the sensor. Verify media compatibility before deployment - the datasheet only characterizes dry air operation, and water or corrosive gases can degrade the die or contaminate the gel-filled port cavity. For wet media applications, install an external hydrophobic membrane filter upstream of the sensor port. Also note that the dual-port configuration requires both ports to be connected to a defined pressure reference; leaving one port open results in undefined gauge pressure behavior.
