MPX2053DP - 50 kPa Differential Pressure Sensor | NXP | 4-SIP Module
The NXP MPX2053DP is a 50 kPa (7.25 PSI) on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor housed in a 4-SIP module with dual barbed ports for differential pressure measurement. It delivers a linear, ratiometric analog voltage output of 0 mV to 40 mV at 10 V excitation, corresponding to a sensitivity of 0.8 mV/kPa over a 0 kPa to 50 kPa differential operating range. The monolithic silicon diaphragm integrates the strain gauge and thin-film resistor network on a single die. A piezoresistive pressure sensor is a MEMS device whose Wheatstone-bridge strain gauges are diffused into a silicon diaphragm that flexes under applied pressure, producing a differential output voltage proportional to the pressure differential across its two ports. In the broader sensor hierarchy, the MPX2053DP sits within pressure sensors -> MEMS sensors -> transducers -> sensors, and is commonly interfaced to instrumentation amplifiers or ADC front ends. Temperature compensation and span/offset calibration are performed by laser-trimmed thin-film resistors on-chip, eliminating the need for external compensation networks in many applications. The MPX2053DP features a typical full-scale span of 40 mV at 10 V supply, a maximum offset of ±1.0 mV, and a response time of 1.0 ms. The device operates from a single 10 V typical supply (maximum 16 V) and is specified over 0 °C to +85 °C. Ratiometric output means the span scales linearly with supply voltage, simplifying ADC interfacing. The dual-port SIP package (Case 344-15) accepts 4.93 mm (0.19 inch) tubing for pneumatic or hydraulic differential measurement. Typical applications include medical instrumentation (respiratory monitors, ventilators, blood pressure monitors), HVAC airflow and filter monitoring, industrial process control, level detection, and barometric differential measurement. The 0.8 mV/kPa sensitivity makes the device well-suited for low-pressure biomedical and environmental sensing. Designers should use a high-precision instrumentation amplifier (such as an INA126 or AD620) to boost the 40 mV full-scale output to a usable 0-5 V or 4-20 mA range. Add 100 nF supply decoupling close to the sensor pins and a resistive bridge-drive configuration if ratiometric ADC sampling is required.

The NXP MPX2053GP is a 50 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor delivering a highly accurate and linear voltage output directly proportional to the applied pressure, housed in a 4-SIP through-hole module with a single radial barbed port. A piezoresistive pressure sensor is a transducer that converts applied mechanical pressure into a proportional electrical signal by exploiting the piezoresistive effect of silicon. In the broader sensor taxonomy it belongs to MEMS pressure sensors, which sit alongside capacitive, optical, and resonant pressure sensing techniques. The MPX2053GP uses a Wheatstone-bridge configuration of implanted silicon resistors on a monolithic diaphragm; when pressure deflects the diaphragm, the bridge produces a differential millivolt output. The MPX2053GP is specifically designed for gauge (vented) pressure measurement referenced to atmospheric pressure through a side vent in the package. Key features of the MPX2053GP include a full-scale range of 50 kPa (7.25 PSI), a sensitivity of 0.8 mV/kPa typical, an output span of 0 mV to 40 mV at 10 V supply, and on-chip temperature compensation across 0°C to 85°C. The device is calibrated and laser-trimmed at the factory, eliminating the need for external compensation networks in most applications. Maximum supply voltage is 16 V, and the device exhibits strong linearity across its operating range. The MPX2053GP architecture consists of a silicon micromachined diaphragm with a piezoresistive Wheatstone bridge, signal-conditioned and laser-trimmed at the wafer level. The single radial port geometry simplifies plumbing and the through-hole 4-SIP package allows easy PCB integration. Internal compensation corrects for temperature-induced span and offset shifts typical of raw piezoresistive bridges. Typical applications include HVAC pressure monitoring, medical respiratory equipment, process control, altimeters and barometers, and industrial pneumatic systems. Its low cost and calibrated output make it well suited for high-volume consumer and industrial designs requiring reliable gauge pressure measurement. When designing with this device, ensure a clean, regulated 10 V supply for specified performance, and account for the millivolt-level output signal by using low-noise instrumentation amplifiers (such as INA128 or AD620) to boost the signal before ADC conversion.

It is part of the legacy MPX2053 family originally introduced by Motorola and now maintained by NXP, designed for direct interface with microcontrollers and A/D converters without external signal conditioning. A piezoresistive pressure sensor is a MEMS device in which a silicon diaphragm with embedded Wheatstone bridge resistors deflects under applied pressure, converting mechanical force into a differential millivolt output proportional to pressure. Pressure sensors sit within the broader transducer hierarchy as part of the sensor signal chain, downstream of physical phenomena and upstream of analog front-end (AFE) or ADC stages in measurement and control systems. Key features include on-chip temperature compensation over the -40 C to +125 C range, calibrated span and offset for drop-in use, a 0 mV to 40 mV full-scale output at 10 V supply, and a vented gauge reference that measures pressure relative to ambient through the rear of the package. The Wheatstone bridge topology provides good linearity and low noise when excited from a stable low-impedance source. Typical applications include HVAC blower and duct pressure monitoring, medical respiratory and ventilator equipment, industrial process control, altitude and barometric sensing, and appliance water-level detection. The vented gauge port design eliminates the need for external barometric correction in differential applications. When designing with this device, decouple the supply with a 100 nF ceramic capacitor close to the supply pin and drive the bridge from a low-noise, low-impedance reference to minimize self-heating and span drift. Use a high-resolution ADC with at least 12 bits to resolve the 40 mV full-scale span.

The NXP Semiconductors (formerly Motorola/Freescale) MPX2100A is a 100 kPa (14.5 psi) absolute pressure sensor in a 4-SIP through-hole module, delivering a linear analog voltage output proportional to applied pressure. It produces a 0 mV to 40 mV full-scale span (typical) at a 10 V supply, with on-chip temperature compensation and calibration across 0°C to 85°C. The device uses a silicon piezoresistive sensing element with a differential amplifier stage on the same die. A piezoresistive pressure sensor is a MEMS device in which four piezoresistors arranged in a Wheatstone bridge on a silicon diaphragm change resistance when the diaphragm flexes under pressure. The MPX2100A belongs to the pressure transducer product family, under MEMS sensors, which in turn sits within the broader sensor hierarchy: pressure sensors -> sensors -> signal conditioning -> data acquisition systems. Absolute-pressure variants (suffix "A") measure pressure referenced to a sealed vacuum cavity on the die, distinct from gauge ("G") or differential ("D") variants. Key features include 40 mV full-scale span (typical), 0 mV to 40 mV output range, 10 V typical supply, ±0.25% linearity (best-fit straight line), ±1.0% temperature hysteresis, and 1.0% full-scale span temperature error. The device provides a sensitivity of approximately 0.4 mV/kPa at 10 V excitation, with an operating temperature range of -40°C to +125°C. Internal calibration eliminates the need for external compensation networks in most applications. The MPX2100A architecture combines a diffused piezoresistive bridge with a thin-film gain network and a laser-trimmed offset adjustment, providing ratiometric output directly proportional to supply voltage. This ratiometric behavior simplifies analog-to-digital conversion when the excitation source also serves as the ADC reference. The unibody 4-SIP package provides port-style pressure access through a single tube inlet. Typical applications include medical instrumentation (blood pressure monitors, respiratory equipment), HVAC pressure measurement, altimeters and barometric systems, industrial process control, and pneumatic controls. The absolute-pressure reference makes the device particularly suitable for sealed-system measurements where atmospheric variation must be excluded. When designing with the MPX2100A, an instrumentation amplifier such as the MCP6N11 or AD8421 is typically required to boost the 40 mV full-scale output to a usable 0-5 V or 4-20 mA range. Use a low-noise, low-drift precision op-amp and provide a clean, regulated 10 V excitation to maintain specified linearity.

MPX2100AP - 100kPa Absolute Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX2100AP is a silicon piezoresistive absolute pressure sensor rated for 0 to 100 kPa (0 to 14.5 psi), housed in a 4-SIP module with an axial male 0.19 inch (4.93 mm) tube port. It delivers a typical full-scale span of 40 mV at 10 V excitation, providing a linear voltage output that is directly proportional to applied pressure. According to the manufacturer datasheet, the sensor integrates a monolithic silicon diaphragm, an on-chip strain gauge, and a thin-film resistor network that is laser-trimmed for span, offset, and on-chip temperature compensation. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a transducer that uses the piezoresistive effect in silicon - where mechanical strain changes carrier mobility - to convert applied pressure into a measurable voltage. Piezoresistive sensors sit in the broader transducer family alongside capacitive, piezoelectric, and resonant sensors, and they are widely used where DC response, low cost, and PCB-mountable packaging are required. The MPX2100AP specifically targets absolute (sealed vacuum reference) pressure measurement rather than differential or gauge measurement. Key features of the MPX2100AP include 0 to 40 mV output span, ±0.25% linearity per the manufacturer datasheet, ±0.5% temperature compensation over 0°C to 85°C, and an operating temperature range of -40°C to +125°C. The uncompensated nature of the output keeps the part economical but requires external signal conditioning - typically an instrumentation amplifier such as the INA125, INA128, or MAX4475 - to amplify the small millivolt signal to a usable 0-5 V or 4-20 mA range. The 4-SIP module provides a robust port for pneumatic or hydraulic coupling in industrial environments. The MPX2100AP uses a Wheatstone-bridge configuration on a single silicon die, which simplifies the external interface to four pins: power, ground, and two differential outputs. This architecture inherently rejects common-mode noise and supports ratiometric measurements when paired with a stable excitation supply. Designers should select a low-drift, low-noise excitation reference to fully exploit the on-chip temperature compensation. Typical applications include medical respirators and ventilators, HVAC pressure monitoring, process control instrumentation, altimeters and barometers, leak detection, and pneumatic system monitoring. The absolute-pressure reference makes it particularly suitable for barometric and sealed-system use, where the device reads absolute rather than differential pressure. A key design consideration is that the 40 mV full-scale output is very small, so PCB trace routing should minimize stray capacitance and thermal EMF; route the differential outputs as a balanced pair to the instrumentation amplifier with proper guarding. For ratiometric measurements, derive the ADC reference from the same 10 V excitation supply to cancel supply-noise errors.

The device produces a 0 mV to 40 mV full-scale output at 10 V excitation, operating over a 14.5 PSI (100 kPa) absolute pressure range. An absolute pressure sensor is a transducer that measures pressure referenced to a sealed vacuum reference chamber rather than ambient atmosphere; this allows accurate altitude-independent pressure readings across wide environmental conditions. The MPX2100 series belongs to the piezoresistive silicon sensor family, sitting within the broader sensor taxonomy: pressure sensor -> board mount pressure sensor -> MEMS sensor -> semiconductor device. Absolute variants are essential in applications where atmospheric pressure varies (e.g., unmanned aerial vehicles, weather instrumentation) because the sealed vacuum reference provides a stable zero point. Key features include on-chip signal conditioning via a monolithic piezoresistive Wheatstone bridge, factory calibration at 10 V excitation, and laser-trimmed resistors for temperature compensation across the operating range. The 4-SIP module package is designed for through-hole PCB mounting with an integrated axial pressure port that accepts a 4.92 mm tube, simplifying pneumatic interfacing in industrial equipment and medical instruments. The MPX2100ASX architecture uses a single silicon diaphragm with diffused piezoresistive strain gauges arranged in a Wheatstone bridge; this monolithic approach reduces part count, eliminates external calibration, and provides robust ratiometric output that scales linearly with excitation voltage. The vacuum reference is hermetically sealed on the rear of the die, ensuring long-term reference stability. Typical applications include barometric pressure measurement in weather stations, altimeters for drones and aviation instrumentation, industrial process control, HVAC pressure monitoring, and medical respiratory equipment such as spirometers and ventilators. The wide operating pressure range and sealed absolute reference also suit vacuum system monitoring and sealed gas pressure applications. When designing with this part, place the 4-SIP module with adequate clearance around the axial tube inlet to ensure reliable pneumatic connection. Use a stable low-noise excitation supply of 10 V DC; ratiometric output means supply noise translates directly into measurement noise, so the supply should be well decoupled.

Inside the broader sensor hierarchy, the MPX2100D belongs to the family of pressure sensors, then to transducers, then to sensors in general, then to signal conditioning and data acquisition subsystems. Differential variants measure the difference between two pressure ports rather than absolute pressure referenced to a sealed vacuum, making them ideal for flow measurement and gauge-pressure applications where the reference side is vented to atmosphere. Key features include a 0.4 mV/kPa nominal sensitivity, a maximum supply voltage of 16 V with a recommended 10 V excitation, and a wide operating temperature range suitable for industrial and medical environments. The unibody SIP package integrates port geometry and provides a rugged mechanical interface. Typical full-scale output is 40 mV at 10 V for 100 kPa applied pressure.

Typical applications include medical respiration and ventilation monitors, HVAC blower and filter pressure sensing, industrial process control, altimeters and barometric instruments, and pneumatic control systems. Across these uses, differential sensing is preferred when one side must be referenced to a known low-pressure environment. When designing with this part, provide low-noise, well-regulated excitation and condition the millivolt-level output with an instrumentation amplifier such as the INA128 or AD620 before ADC conversion.

As pressure deforms the diaphragm, the embedded Wheatstone bridge produces a differential voltage proportional to the pressure differential between the two ports. The MPX2100DP sits within the broader sensor hierarchy: pressure sensor -> MEMS transducer -> board-mount sensor -> electronic component. The 4-SIP package with axial tubes makes it suitable for through-hole mounting on PCBs and inline pneumatic systems, distinguishing it from surface-mount MEMS alternatives. Key features include a 0-100 kPa measurement range, 40 mV full-scale span, 1.0% typical linearity, and on-chip temperature compensation over 0-85°C.

It measures a 0 to 100 kPa (0 to 14.5 psi) vented gauge pressure range and delivers a full-scale span of 40 mV typical at 10 V supply, with on-chip temperature compensation and calibration already applied. A pressure sensor transducer generates an electronic signal proportional to the applied pressure, typically by exploiting the piezoresistive effect in silicon. The MPX2100GP belongs to the board-mount pressure sensor family, a subset of signal-conditioning sensors that sit between the physical environment and the microcontroller analog front end. In the broader sensor taxonomy it falls under silicon MEMS -> piezoresistive sensor -> board mount pressure sensor -> signal chain component. Key features include a maximum operating current of 6 mA, a Wheatstone bridge output topology, 58.02 psi (400 kPa) maximum overpressure rating, and an operating temperature range suited for industrial environments. The on-chip temperature compensation eliminates the need for external compensation networks, simplifying the analog front end. The 4-SIP module with port-style barbed tube integrates the sensing element and the compensation network into a single through-hole package that is easy to mount and seal with flexible tubing. Technically, the device uses a diffused silicon strain gauge Wheatstone bridge laser-trimmed for span and offset, then temperature-compensated across 0 to 85°C. The differential output of 0 mV to 40 mV over 0 to 100 kPa gives ~0.4 mV/kPa sensitivity, which is normally amplified by an instrumentation amplifier such as the NXP MPX2010 family counterpart or a dedicated sensor AFE. Typical applications include HVAC controllers, altimeters and barometric instruments, medical respiration monitors, industrial pneumatic gauges, and weather-station barometric pressure sensing. The 4-SIP barbed port supports flexible tubing routing for sealed pressure taps in pneumatic manifolds. When designing with the MPX2100GP, allow adequate mechanical strain relief on the tube port and provide a stable low-noise 10 V excitation supply. The Wheatstone bridge output is ratiometric to supply voltage, so any supply noise or ripple couples directly into the output.

MPX2100GVP - 100 kPa Vented Gauge Pressure Sensor | NXP Semiconductors
The NXP Semiconductors MPX2100GVP is a 100 kPa (14.5 psi) on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor in a 4-SIP through-hole module with a 0.19 inch (4.93 mm) male pressure port. It delivers a highly accurate, linear analog voltage output of 0 mV to 40 mV at 10 V supply, directly proportional to applied pressure. The sensor uses a vented gauge configuration, meaning it references atmospheric pressure on one side of the diaphragm, making it suitable for applications where relative barometric pressure must be measured. A pressure sensor is a transducer that converts an applied mechanical pressure into a proportional electrical signal. Within the broader sensor hierarchy, piezoresistive silicon pressure sensors belong to the MEMS (Micro-Electro-Mechanical Systems) family, which sits under the wider category of physical sensors and ultimately under signal-conditioning and data-acquisition components. These devices typically rely on a Wheatstone-bridge network diffused into a silicon diaphragm; when pressure deflects the diaphragm, the bridge resistors change value and produce a differential output. On-chip temperature compensation maintains accuracy across commercial and industrial temperature ranges, eliminating the need for external linearization in many designs. The MPX2100GVP integrates the sensing element, signal conditioning, and temperature compensation on a single silicon die. Its full-scale span of 40 mV is calibrated directly by the manufacturer, simplifying the host-side interface to a simple ADC channel or instrumentation amplifier. Operating from a 10 V typical supply (3 V minimum specified for the family, full performance at 10 V), the part draws only 6 mA. The 4-SIP through-hole package with ported tube inlet simplifies hose/fitting integration in industrial equipment, medical instrumentation, and HVAC systems. Maximum operating temperature reaches 125 degrees Celsius, supporting engine-bay and process-control environments. Typical applications include pneumatic control systems, respiratory and medical monitoring equipment, gas-flow instrumentation, altimeters and barometric measurement, and industrial process controllers. The vented-gauge topology means absolute vacuum reads as 0 kPa, and the device rejects common-mode supply noise due to its bridge output structure. When designing with the MPX2100GVP, place a precision instrumentation amplifier (such as an INA125 or AD620) immediately after the sensor output to boost the millivolt-level signal before it reaches the ADC. Add adequate EMI/RFI shielding because the high-impedance bridge output is susceptible to interference. Provide a clean, regulated supply because output is ratiometric to supply voltage.

The MPX2102A belongs to the silicon piezoresistive sensor family, where a single monolithic silicon diaphragm integrates the strain gauge and a thin-film resistor network on-chip; the chip is laser-trimmed for precise span, offset, and temperature compensation across its operating range. Within the broader taxonomy, the part is a MEMS pressure transducer, which sits under sensors > pressure sensors in the electronics hierarchy. Key differentiating features of the MPX2102A include the absolute pressure reference (sealed vacuum on the reference side of the diaphragm), an on-chip thin-film temperature compensation network calibrated at the factory, an operating temperature range from -40C to +125C, and a typical full-scale span of 40 mV at 10 V supply. The 4-SIP module package (Case 344-15) provides a robust through-hole mounting style with barbed pressure port for hose attachment, suitable for industrial and medical use cases. The MPX2102A uses a Wheatstone-bridge configuration formed by the on-chip piezoresistors; when pressure deflects the silicon diaphragm, the bridge unbalances and produces a differential millivolt-level output that is proportional to the pressure differential. Because the output is in the millivolt range, designers should pair the sensor with a low-noise, high-CMRR instrumentation amplifier such as an INA128 or AD620 when high resolution is required. Typical applications include medical instrumentation such as respirators and blood pressure monitors, industrial process control, HVAC barometric measurement, altimeters, vacuum system monitoring, and automotive manifold absolute pressure (MAP) sensing. The on-chip temperature compensation eliminates the need for external RTC or thermistor linearization, simplifying firmware. When integrating the MPX2102A, route the four SIP pins through a low-noise differential ADC front-end and include a 5 kHz low-pass RC filter at the sensor outputs to suppress EMI. The output is ratiometric to the supply, so a stable, low-noise 10 V excitation is critical for achieving the datasheet's 0.25% linearity performance.

The 4-SIP barbed port also simplifies integration with silicone tubing for medical and analytical instrumentation. When designing with this part, place a low-offset, low-noise instrumentation amplifier (such as an INA126 or AD620 family) directly at the sensor output to amplify the 40 mV signal to a usable ADC input range. Provide a stable low-noise 10 V excitation (e.g. REF02 or equivalent) to preserve ratiometric accuracy, and isolate the analog and digital grounds with proper star-grounding.

It is a silicon piezoresistive device with an on-chip thin-film resistor network laser-trimmed for span, offset, and temperature compensation, delivering a highly accurate, low-drift pressure-to-voltage transfer in a single monolithic diaphragm. A pressure sensor, also known as a pressure transducer, is a device that converts an applied gas or fluid pressure into a proportional electrical signal. Piezoresistive sensors exploit the change in resistance of silicon strain gauges embedded in a flexible diaphragm; as the diaphragm deflects under pressure, the gauges stretch or compress, and a Wheatstone bridge produces a differential output voltage. Pressure sensors belong to the broader class of transducers, which convert one form of energy into another, and they are key building blocks within the Sensors hierarchy (sensor -> transducer -> pressure sensor -> piezoresistive pressure sensor -> absolute pressure sensor) used across industrial, medical, and consumer electronics. Key specifications include an operating pressure range of 0 to 100 kPa (0 to 14.5 PSI absolute), a full-scale span of 40 mV at 10 V supply, an offset of 0 mV to 1.0 mV, and a temperature-compensated range of 0 to 85 degrees Celsius. The device is factory calibrated for span and offset, eliminating the need for external trimming components in most designs. The monolithic die incorporates four piezoresistors arranged as a Wheatstone bridge on a silicon diaphragm; a thin-film laser-trimmed network compensates temperature behaviour across the 0 to 85 degrees Celsius range, simplifying downstream signal conditioning.

The NXP MPX2102D is a 100 kPa on-chip temperature-compensated silicon piezoresistive pressure sensor housed in a 4-SIP through-hole module. The device delivers a highly accurate, linear Wheatstone Bridge analog voltage output of 0 mV to 40 mV at a 10 V excitation supply, directly proportional to the applied pressure. According to the NXP datasheet, the MPX2102D is rated for a 14.5 PSI (100 kPa) differential pressure operating range and is calibrated directly on the die for high accuracy. A piezoresistive pressure sensor is a MEMS device that converts applied mechanical pressure into a proportional electrical signal using strain-sensitive resistors embedded in a silicon diaphragm. When pressure deforms the diaphragm, the embedded Wheatstone bridge resistors change resistance, producing a differential output voltage. Piezoresistive sensors such as the MPX2102D sit at the bottom of the sensor hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor IC. They are widely used where continuous analog pressure monitoring is required rather than a simple threshold switch. Key features of the MPX2102D include on-chip temperature compensation from 0 C to +85 C, a 0 mV to 40 mV full-scale output, a typical full-scale span of 40 mV at 10 V supply, low offse drift, and a rugged unibody 4-SIP package with dual pressure ports for differential measurement. The integrated signal conditioning and calibration performed at the wafer level eliminate the need for external compensation networks, simplifying downstream amplifier design. The die uses a piezoresistive Wheatstone bridge configured for differential pressure sensing, with a separate reference port exposed on the side of the 4-SIP module opposite the high-pressure port. The on-chip laser-trimmed resistors provide temperature compensation across the rated range, which is essential because raw silicon piezoresistors exhibit strong temperature coefficients that would otherwise degrade measurement accuracy. Typical applications include HVAC airflow monitoring, medical respiration and anesthesia equipment, industrial process control, altimeters and barometric instrumentation, and pneumatic control systems. Its differential measurement capability also makes it well-suited to liquid-level sensing via hydrostatic pressure. When designing with the MPX2102D, ensure that the 10 V excitation supply is well-regulated because output accuracy scales linearly with supply voltage. The Wheatstone bridge output is in the millivolt range and typically requires an instrumentation amplifier such as the INA128 or AD620 before the ADC input. Differential measurements should use both pressure ports and avoid clogging either with particulates.

MPX2102DP - 100kPa Differential Pressure Sensor, 4-SIP | NXP
The NXP MPX2102DP is a 100 kPa on-chip temperature compensated silicon piezoresistive pressure sensor housed in a 4-SIP Dual Port module with 0.19" (4.93 mm) tube ports. A pressure sensor is a transducer that converts an applied pressure into a proportional analog electrical signal; the MPX2102 uses a monolithic silicon diaphragm with an integrated thin-film resistor strain-gauge network, laser-trimmed for high accuracy and linearity, so the differential output between P1 and P2 ports produces a ratiometric voltage directly proportional to applied pressure. Within the broader sensor taxonomy, this part is a piezoresistive MEMS pressure sensor belonging to the micro-electromechanical signal chain, commonly grouped alongside load cells and strain-gauge transducers in industrial and medical instrumentation. Key features include a 0–100 kPa (0–14.5 PSI) differential operating range, 0 mV to 40 mV full-scale output at 10 V excitation, on-chip temperature compensation from 0 °C to +85 °C, and a typical full-scale span of 40 mV that simplifies downstream ADC conditioning. The unibody 4-SIP package integrates the port tube, die, and compensation network, eliminating external temperature-calibration circuitry. The architecture uses a piezoresistive Wheatstone bridge where four diffused resistors change resistance proportionally to membrane stress; the differential bridge output is ratiometric to the supply, so noise-rejection improves when the sensor shares a clean, low-ripple 10 V reference with the ADC. Full-scale span drift is held within ±0.5 % over the compensated temperature range, which is acceptable for medical inhalation and industrial pneumatic control loops. Typical applications include medical spirometers and respirators, HVAC variable-air-volume boxes, process-control pneumatic transmitters, barometric altimeters for portable instrumentation, and industrial pneumatic regulators where differential pressure across an orifice plate must be linearized at the system level. When designing with the MPX2102DP, place a low-offset instrumentation amplifier (e.g., INA125 or AD620) within 100 mm of the sensor pins to avoid injecting PCB leakage drift into the millivolt signal, and decouple the 10 V excitation rail with a 100 nF ceramic capacitor adjacent to Vcc to suppress bridge noise.

MPX2102GP - 100kPa Vented Gauge Pressure Sensor | NXP
The NXP MPX2102GP is a 100 kPa (14.5 PSI) on-chip temperature compensated silicon piezoresistive pressure sensor housed in a 4-SIP Module (Unibody GP package) with a 0.19" (4.93 mm) pressure port. It provides a linear, accurate voltage output of 0 mV to 40 mV at 10 V excitation directly proportional to applied pressure, with vented gauge configuration for absolute atmospheric reference. A piezoresistive pressure sensor is a MEMS device in which strain gauges integrated on a silicon diaphragm change resistance when pressure deflects the membrane. The sensor therefore sits within the broader hierarchy: pressure sensor -> pressure transducer -> sensor IC -> semiconductor, and is commonly used wherever a microcontroller or ADC must read a physical pressure value as an analog voltage. The MPX2102 series adds on-chip thin-film resistor networks that are laser-trimmed for gain and offset calibration and temperature compensated across the 0 C to +85 C range, removing most of the external compensation that earlier raw bridge sensors required. Key features include a 0 to 100 kPa (0 to 14.5 PSI) operating range, full-scale output of 40 mV at 10 V supply, sensitivity of approximately 0.4 mV/kPa, differential vented-gauge topology, 1.0 % maximum linearity, and integrated temperature compensation from 0 C to +85 C. The unibody package provides a single-piece stress-isolated silicon die, eliminating plastic-to-silicon thermal mismatch and improving long-term drift compared with epoxy-mounted designs. The architecture uses a single monolithic silicon diaphragm with the strain gauge and thin-film resistor network integrated on-chip. Laser trimming during wafer fab calibrates offset and span so each unit is interchangeable without per-device trimming. The vented-gauge port exposes the back side of the die to atmosphere through the housing, so the output always references ambient barometric pressure rather than a sealed vacuum - important for weather, respiration, and altitude-relative instrumentation. Typical applications include medical respiration and CPAP airflow monitoring, HVAC and air-flow meters, altitude and barometric reference sensing, industrial pneumatic pressure monitoring, weather stations, and altitude-correcting instrumentation for drones or wearables. The 40 mV full-scale swing is well-matched to instrumentation amplifiers and 12-bit ADC front ends. When designing with this device, plan for a high-gain instrumentation amplifier stage after the bridge because the native 40 mV output is small. Use a stable low-noise 10 V excitation supply because span and offset track Vexcitation; any ripple on Vexcitation becomes ripple on the output. Apply conformal coating or potting if the vented port is exposed to condensing humidity.

MPX2102GVP - 100 kPa Vented Gauge Pressure Sensor | NXP
The NXP MPX2102GVP is a 100 kPa on-chip temperature-compensated silicon piezoresistive pressure sensor housed in a 4-SIP top-port module with a 0.19 inch (4.93 mm) tube inlet. The device delivers a linear analog output of 0 mV to 40 mV at 10 V excitation spanning a vented gauge pressure range of 0 to 14.5 PSI (100 kPa). A pressure sensor is a transducer that converts an applied pneumatic or hydraulic force into a proportional electrical signal, serving as the sensing layer between a physical medium and an electronic measurement system. Within the broader instrumentation hierarchy, the MPX2102GVP belongs to the family of piezoresistive (strain-gauge) sensors, then to MEMS silicon sensors, and finally to signal-conditioning transducers. The piezoresistive principle uses diffused silicon strain gauges whose resistance changes with diaphragm deflection, providing higher sensitivity and smaller form factors than legacy metal-foil gauges. The MPX2102 series integrates a monolithic silicon diaphragm with laser-trimmed thin-film resistors, providing a temperature-compensated output across 0 C to 85 C. Sensitivity is typically 0.4 mV/kPa when excited at the recommended 10 V supply, and the device exhibits strong linearity across its full-scale range. The 4-SIP module packages the die with a vertical inlet port that simplifies tube fitting in medical and industrial manifolds. Key features include a maximum pressure rating well above the operating span to survive pressure spikes, EMI/RFI insensitivity inherent to differential Wheatstone-bridge sensing, and a robust molded package suitable for non-corrosive gas media. The bridge impedance is nominally high (approximately 400 ohm to 500 ohm), so a low-noise instrumentation amplifier is recommended to buffer and amplify the millivolt-level signal. Typical applications include respiratory and CPAP airflow monitoring, barometric compensation for weather stations and altimeters, HVAC duct pressure measurement, pneumatic leak detection, and industrial process control loops where a low-pressure differential must be digitized. The vented gauge reference (side opposite the inlet) lets the sensor output correct for atmospheric pressure changes, unlike sealed gauge devices. When designing with this part, use a low-offset, low-drift op-amp such as a zero-drift chopper amplifier to preserve the small-signal accuracy; lead-length-induced errors and self-heating should also be minimized. A stable 10 V excitation rail is required to take full advantage of the calibrated transfer function.

MPX2200A - 200 kPa Absolute Pressure Sensor, 10V, 4-SIP | NXP
The NXP MPX2200A is a 200 kPa on-chip temperature compensated silicon piezoresistive pressure sensor that delivers a highly accurate, linear voltage output directly proportional to applied absolute pressure, housed in a unibody 4-SIP through-hole module. Headline parameters: 0 to 200 kPa (0 to 29.01 PSI) absolute operating range, 0 to 40 mV full-scale span at 10 V excitation, and 116.03 PSI (800 kPa) maximum overpressure rating. The device integrates a Wheatstone bridge of silicon piezoresistive strain gauges laser-trimmed for temperature compensation and offset nulling. 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. This page synthesizes distributor pricing, drop-in alternatives within the MPX2200 family, and practical design notes not found in a single source - including parameter comparisons against MPX2200AP/GP/DP variants and guidance on ratiometric ADC interfacing.
MPX2200A117 - 200 kPa Absolute Pressure Sensor | NXP Semiconductors
The NXP MPX2200A117 is a 200 kPa absolute, on-chip temperature-compensated and calibrated silicon pressure sensor supplied in a 4-SIP through-hole module (case 117). It is designed for systems that digitize or condition a piezoresistive Wheatstone-bridge output signal with a single supply between 6 V and 16 V (max 20 V), delivering a full-scale span of 40 mV nominal at 10 V excitation. A pressure sensor, also called a pressure transducer, is a device that converts an applied differential or absolute pressure into a proportional electrical signal. The MPX2200A belongs to the MPX family of piezoresistive sensors, which sit in the broader transducer category below analog signal-chain components and above raw MEMS diaphragms. By integrating the strain-gauge bridge, temperature compensation, signal conditioning, and ESD protection on a single monolithic silicon die, NXP produces a calibrated transducer that requires only an external amplifier and ADC to deliver a digital pressure reading. Key features include a 0 kPa to 200 kPa absolute operating range (approximately 29.01 psi), a typical full-scale span of 40 mV at 10 V excitation with a measured offset trim range that supports zero calibration, an industry-leading accuracy of ±0.25 %V FSS when externally amplified and corrected, and a temperature-compensated range of 0 °C to +85 °C. The integrated laser-trimmed thin-film network calibrates span and offset over the compensated temperature range, eliminating most software polynomial correction in the host MCU. Architecturally, the MPX2200A employs a proprietary Monolithic Silicon Strain Gauge (MSSG) process that places the piezoresistors on a chemically etched silicon diaphragm. The diaphragm deflection is proportional to applied pressure; the resulting bridge imbalance is amplified by internal thin-film resistors and laser-trimmed for span accuracy. The result is a ratiometric analog output with low temperature coefficient of span (< -1.0 %V FSS over 0 to 85 °C) and stable long-term repeatability. Typical applications include medical respiration monitors, HVAC air-flow controllers, industrial process control loops, altitude measurement for drones and avionics, and consumer weather stations. In a CPAP or ventilator use-case, the 0 to 200 kPa absolute range directly maps to airway pressure while the 10 V excitation span simplifies the front-end ADC reference design. Engineers should treat the 40 mV full-scale span as a low-level signal: place a low-offset, low-noise instrumentation amplifier within 50 mm of the sensor pins, use a Kelvin connection to the excitation source, and add a small RC filter (typ. 1 kohm + 10 nF) to suppress EMI. Because the silicon die is sensitive to humid environments, the case-117 housing should be sealed with an O-ring in any liquid-coupled installation.

MPX2200AP - 200 kPa Absolute Pressure Sensor 4-SIP | NXP
The NXP MPX2200AP is a 200 kPa on-chip temperature-compensated silicon piezoresistive pressure sensor in a 4-SIP through-hole module with axial pressure port. Pressure output of 0 mV to 40 mV at 10 V excitation, with absolute pressure reference and full-scale span of 29.01 PSI (200 kPa). The device provides a highly accurate and linear voltage output directly proportional to applied pressure, and is one of the legacy MPX2200 series devices originally developed by Motorola and now produced by NXP and STMicroelectronics. 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.
MPX2200D - 200kPa Differential Pressure Sensor 4-SIP | STMicroelectronics
The STMicroelectronics MPX2200D is a 200 kPa on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor in a 4-SIP module, providing a highly accurate and linear voltage output directly proportional to the applied differential pressure. A piezoresistive pressure sensor is a MEMS device in which four silicon strain gauges arranged in a Wheatstone bridge change resistance when mechanical pressure deflects a thin silicon diaphragm. The differential configuration (suffix "D") measures the pressure difference between two ports, rather than the absolute or gauge value relative to a sealed vacuum reference. Pressure sensors occupy the transducer layer of any measurement signal chain, sitting between the physical process variable and the analog signal-conditioning front end. The MPX2200D delivers a 0 mV to 40 mV differential output at 200 kPa (29.01 PSI) full-scale pressure when excited with a 10 V supply, with on-chip temperature compensation over 0C to +85C, ±0.25% linearity, and ±1% maximum pressure hysteresis. The single-port side and dual-port side process connections accept standard 3.45 mm (0.136 in) barbed pressure fittings, while the through-hole 4-SIP module (Case 344-15) is compatible with PCB-mount assembly. Typical applications include industrial process control (hydraulic and pneumatic pressure monitoring), medical instrumentation (respiratory and infusion pumps), HVAC duct sensing, altimeters and barometric instruments, and consumer appliance water-level detection. The differential topology is particularly useful where bidirectional flow or vacuum-to-positive pressure measurement is required. When designing with the MPX2200D, an instrumentation amplifier with low offset drift (such as the INA125 or AD620) is typically used to amplify the 40 mV full-scale output to a useful ADC input range. Add a common-mode RC filter at the sensor output to attenuate EMI from motor or relay switching in industrial environments.
MPX2200DP - 200 kPa Differential Pressure Sensor, 4-SIP Module
The NXP (originally Motorola) MPX2200DP is a 200 kPa on-chip temperature-compensated silicon piezoresistive pressure sensor housed in a 4-SIP through-hole module with dual-port tube inlet (4.93 mm / 0.19 in). It delivers a highly accurate, linear differential voltage output directly proportional to applied pressure, with a full-scale span of 0 mV to 40 mV at the 10 V excitation specified by the manufacturer. The dual-port (DP) port configuration allows the device to measure one pressure against another reference pressure for gauge-differential applications such as flow elements and process control. A piezoresistive pressure sensor is a MEMS (micro-electromechanical systems) device in which a silicon diaphragm is etched with embedded strain-gauge elements whose resistance changes proportionally to the mechanical strain caused by the differential pressure across the diaphragm. The on-chip temperature compensation and calibration network, electronically adjusted against the bias, normalizes the output across the -40C to +125C operating range, removing the need for external linearization circuitry in many embedded designs. Within the broader taxonomy, this places the MPX2200DP in the hierarchy: piezoresistive pressure sensor -> pressure sensor -> MEMS sensor -> transducer -> sensor. Key differentiating features of the MPX2200DP include a differential operating pressure range of 0 to 200 kPa (29.01 PSI), 0 mV to 40 mV output span at 10 V excitation, 0.2 mV/kPa nominal sensitivity, integrated on-chip temperature compensation, ratiometric output relative to supply, and a maximum supply of 5 V input (industry-standard excitation limit) with absolute maximum of 16 V. The single inline package (4-SIP) form factor with two parallel ports simplifies mechanical mounting in pneumatic and hydraulic manifolds, while the through-hole die-cast package offers robust mechanical stability in vibration-prone environments. Typical applications include industrial process controls, medical instrumentation such as respiratory and patient monitoring, HVAC pressure monitoring, altimeters and barometric systems, engine control and fuel-pressure monitoring, and level measurement. Its differential architecture makes it especially suited to measuring pressure drops across filters, valves, and flow-restriction orifices where a gauge sensor would not provide accurate dynamic readings. When designing with this device, ensure a clean, regulated 5 V to 10 V excitation supply and a stable low-impedance reference to preserve the ratiometric accuracy of the output. Use an instrumentation amplifier with low offset and low drift to extract the small mV-level signal, and apply a low-pass filter to remove high-frequency noise from pumps and motors in the surrounding system.

MPX2200GP - 200 kPa Vented Gauge Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX2200GP is a silicon piezoresistive pressure sensor that delivers a highly accurate, linear voltage output directly proportional to applied pressure, in a 4-SIP through-hole module. The device is rated for a 200 kPa (29.01 PSI) full-scale vented-gauge pressure range with a typical full-scale span of 40 mV at 10 V excitation, and on-chip temperature compensation and laser-trimmed calibration provide stable offset and span over the operating range. 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.
MPX2202A - 200kPa Absolute Pressure Sensor, 4-SIP | NXP
The NXP MPX2202A is a 200 kPa on-chip temperature-compensated silicon piezoresistive pressure sensor that delivers a highly accurate, linear analog voltage output directly proportional to the applied absolute pressure. The device operates from a 10V (16V max) supply and produces 0 mV to 40 mV full-scale output across the 0 kPa to 200 kPa (29.01 PSI) pressure range, housed in a unibody 4-SIP through-hole module with a Cell w/Body O-Ring port. A pressure sensor is a transducer which converts an applied physical pressure into a measurable electrical signal. Within the broader sensor hierarchy, the MPX2202A belongs to the piezoresistive silicon pressure-sensor family, itself a subclass of MEMS sensors under the wider Sensors > Pressure Sensors category. Piezoresistive devices use diffused strain gauges on a silicon diaphragm whose resistance changes with applied pressure; the on-chip signal conditioning and temperature compensation deliver a calibrated, near-linear voltage output without the user needing to add external linearization circuitry. Key features include 0.4 mV/kPa nominal sensitivity, ±0.25% linearity over the compensated range, on-chip temperature compensation from 0°C to +85°C, and a unibody package that integrates the port, diaphragm, and sensing die. The 4-SIP through-hole form factor is industry-standard for the legacy MPX-series, allowing drop-in compatibility with older MPX2010/MPX2200 designs using the same footprint. The MPX2202A series (MPX2202, MPXV2202G, MPXM2202) leverages Motorola/Freescale/NXP piezoresistive technology. The silicon die is laser-trimmed for zero-pressure offset and full-scale span, with additional thin-film resistors integrated for active temperature compensation across the industrial 0°C to +85°C range. Common applications include medical instrumentation (respiratory monitors, blood-pressure cuffs, infusion pumps), industrial process control (HVAC, pneumatic systems), altimeters and barometers, and consumer appliances. The absolute pressure reference (sealed vacuum on the back side of the die) means output is referenced to vacuum rather than ambient, making it ideal for altitude measurement and sealed system monitoring. When designing with this part, ensure the supply is regulated to 10V nominal for rated performance and apply a low-noise instrumentation amplifier (e.g., INA128, AD620) directly at the SIP pins to avoid noise pickup over the millivolt-level signal path. Use a porous PTFE filter on the pressure port for harsh-media applications.
