MPVZ5010G7U - 10 kPa Vented Gauge Pressure Sensor, 8-DIP | NXP
The NXP MPVZ5010G7U is an integrated silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, delivering an analog output of 0.2 V to 4.7 V proportional to a 0 kPa to 10 kPa (1.45 PSI) vented gauge pressure range, housed in an 8-pin DIP through-hole module. What is a board-mount pressure sensor? A board-mount pressure sensor (also called a board-mount pressure transducer) is a self-contained module that converts an applied pressure into an electrical signal using a micromachined silicon diaphragm and on-chip signal conditioning. Pressure sensors sit within the broader sensor hierarchy as: pressure sensor -> force/pressure transducer -> board-mount sensor -> MEMS device -> semiconductor component. The "vented gauge" configuration means the sensor references atmospheric pressure on one side via an integrated vent tube, so the output reflects differential pressure relative to ambient. Key features include a supply voltage range of 4.75 V to 5.25 V (5 V typical), a calibrated analog output spanning 0.2 V at 0 kPa to 4.7 V at 10 kPa, ±1.5 %FS accuracy over 0 °C to 85 °C, and integral temperature compensation that eliminates the need for external calibration. The device also provides EMC hardening, RFI protection, and a rugged epoxy package rated for -10 °C to +60 °C compensation with 0 °C to 85 °C operating range. The MPVZ5010G7U combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing to provide an accurate, ratiometric analog output signal proportional to the applied pressure. Because the output scales with supply voltage (Vout/Vcc ratio), straightforward ADC conversion is achieved with any microcontroller featuring a 5 V-tolerant A/D input. Typical applications include HVAC variable-air-volume (VAV) control, building/Room pressure monitoring, weather station pressure sensing, medical respiratory equipment (CPAP, ventilators), and industrial process control. When designing with this device, ensure that the high-impedance ADC input of the host microcontroller does not load the sensor output and that adequate decoupling is placed near Vcc. The vent tube must remain free of obstruction for accurate gauge readings.

MPVZ5010GW6U - 0-10kPa Pressure Sensor, 5V, SOP-8 | NXP
The NXP Semiconductors MPVZ5010GW6U is a monolithic silicon piezoresistive pressure sensor rated 0 to 10 kPa (0 to 1.45 PSI) with a calibrated, temperature-compensated analog output spanning 0.2 V to 4.7 V when operated from a 5 V supply. The device is housed in an 8-pin SOP package with a top-facing axial pressure port designed for hose or tubing connection, integrating on-chip signal conditioning so the output can be read directly by an MCU ADC without external amplification. Piezoresistive pressure sensors are transducers that convert an applied mechanical pressure into a proportional electrical signal through the piezoresistive effect in doped silicon. The MPVZ5010GW6U belongs to the MPXx5010 family of integrated silicon pressure sensors, sitting within the broader hierarchy of pressure sensor -> MEMS sensor -> transducer -> sensor IC. By integrating the strain-gauge bridge, temperature compensation, and calibration into a single silicon die, this product class eliminates the discrete op-amp and reference circuits required by raw bridge sensors, simplifying host-side firmware. Key features include a 5 V typical supply, full-scale output of 4.7 V at 10 kPa, accuracy of ±1.5% over 0°C to 85°C, and a vented-gauge reference that compensates for ambient barometric pressure drift. The 8-SMD gull-wing package with a 5.59 mm tube-style port supports pneumatic manifold mounting, while the ratiometric output scales proportionally with supply voltage for ADC-friendly conversion. The calibration and on-chip signal conditioning minimize board space and external part count. The transducer uses bipolar processing combined with thin-film metallization and advanced micromachining techniques, producing a high-level analog output. The built-in temperature compensation and calibration deliver stable readings across the operating temperature range, making the part suitable for applications where host-side compensation is impractical or where field calibration is difficult. Typical applications include medical respiratory monitoring, HVAC air-flow sensing, industrial vacuum monitoring, barometric reference, and appliance pressure feedback. Its low-voltage 0.2 V near-zero offset (referenced to vacuum) makes it straightforward to detect blocked filter conditions or vacuum-leak events in pump-driven systems. When designing with this device, plan the pneumatic interface carefully: the axial port accepts 5.59 mm tubing, and the vented-gauge reference must remain unobstructed for accurate readings. Decouple VDD with a 0.1 µF ceramic capacitor placed within 5 mm of the supply pin, and condition the analog output with a simple RC low-pass filter if the application reads the ADC faster than 1 kHz.

MPVZ5010GW7U - 10 kPa Vented Gauge Pressure Sensor | NXP
The NXP MPVZ5010GW7U is a 10 kPa piezoresistive, vented-gauge pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, housed in an 8-pin SOP module with a 0.22" (5.59 mm) top port tube. Per the NXP product brief, it is designed to deliver a ratiometric analog output of 0.2 V to 4.7 V from a 5 V supply, corresponding to 0 kPa to 10 kPa applied gauge pressure. The device is part of the MPxx5010 family of monolithic silicon pressure sensors. What is a vented-gauge pressure sensor? A vented-gauge pressure transducer measures pressure relative to a built-in atmospheric reference port, so the output reflects only the differential between the applied pressure and ambient barometric pressure; this contrasts with absolute sensors that reference a sealed vacuum. The MPVZ5010G integrates a micromachined piezoresistive bridge, thin-film signal-conditioning circuitry, and a laser-trimmed calibration network, producing an output that connects directly to an MCU or microprocessor analog-to-digital input without external signal conditioning. Key features include a calibrated output span of 4.5 V nominal (0.2 V to 4.7 V) and a response time of 1.0 ms typical, plus temperature compensation from 0°C to 85°C. The 8-SOP module package provides port isolation and easy mounting on consumer and industrial printed-circuit assemblies. The integrated EEPROM-trimmed calibration eliminates the need for external potentiometers or compensation components. Technically, the part uses single-port, on-chip bipolar signal-processing circuitry paired with a piezoresistive strain-gauge bridge diffused into the silicon diaphragm. The result is a system-level accuracy of approximately ±1.5% over the compensated temperature range, with the calibration coefficients stored on-chip during final test. The series also includes MPX5010/MPXV5010G variants that share the same silicon die but in different port and package configurations. Typical applications include HVAC blower pressure monitoring, medical respiratory equipment, water-level and weather-station measurement, and consumer appliance pressure detection. For instance, the 4.5 V full-scale output and 1 ms response make it a common fit for residential variable-speed blower monitoring, where airflow-derived pressure changes are translated into MCU-controlled fan curves. Designers should provide clean, regulated 5 V power and route the analog output away from switching-node noise; the device is factory-calibrated for 5 V operation, and using a lower supply will proportionally reduce the output span. Add 100 nF and 1 µF decoupling near VDD and GND to suppress supply-ripple noise that directly couples into the ratiometric output. This page synthesizes distributor pricing (DigiKey/Mouser/NXP), drop-in alternatives within the MPxx5010 family, and design notes not duplicated from the manufacturer datasheet, giving engineers a fast pre-selection view before committing to a full bill of materials.
MPVZ5050GW7U - 50kPa Vented Gauge Pressure Sensor | NXP
The NXP MPVZ5050GW7U is an integrated silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, housed in an 8-pin DIP module (Case 1560-02) with a male 0.22" (5.59 mm) tube port. It measures vented gauge pressure from 0 kPa to 50 kPa (0 to 7.25 PSI) and outputs an analog voltage proportional to pressure, typically 0.2 V at 0 kPa and 4.7 V at 50 kPa from a 5 V supply. A pressure sensor is a transducer that converts an applied pressure into an electrical signal. Piezoresistive sensors exploit the change in resistance of semiconductor strain gauges embedded in a silicon diaphragm; when pressure deflects the diaphragm, the embedded Wheatstone bridge produces a differential voltage that is then amplified and offset-corrected on-chip. Integrated pressure sensors belong to the broader category of MEMS sensors, which combine mechanical microstructures with signal-conditioning circuitry on a single silicon die. This integration delivers a calibrated, ratiometric output that can be fed directly to an analog-to-digital converter. Key features of the MPVZ5050GW7U include 5 V supply operation, on-chip bipolar op-amp signal conditioning, thin-film resistor networks for temperature compensation across 0 °C to 85 °C, a sensitivity of 90 mV/V (4.5 V full-scale span), and a ratiometric analog output. The proprietary single-element transducer design eliminates the need for external compensation components, simplifying PCB design and reducing BOM cost. The 8-DIP through-hole package with side port allows easy prototyping and field-replaceable assembly in manifold-style applications. Typical applications include manifold absolute pressure (MAP) sensing in engine control units, barometric pressure measurement for weather instruments and altimeters, HVAC duct pressure monitoring, and industrial process control. The vented gauge configuration references pressure against ambient atmosphere through the integrated port, making it suitable for differential measurements where one side is always exposed to ambient. When designing with this part, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin to suppress switching noise from upstream regulators. Because the output is ratiometric, any ripple on the 5 V rail translates directly to output error; use a low-noise LDO rather than a switching converter when ADC accuracy below 1 %FS is required.

MPVZ5150GC7U - 150kPa Vented Gauge Pressure Sensor | NXP
The NXP MPVZ5150GC7U is an integrated silicon pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, designed for a wide range of microcontroller and microprocessor applications. Housed in an 8-pin DIP (Case 867F) package, it provides an analog output of 0.2 V to 4.7 V proportional to applied pressure over a 0 to 150 kPa (0 to 21.76 PSI) vented gauge range, with a top-port male 0.13" (3.17 mm) tube interface. A piezoresistive transducer, also called a MEMS pressure sensor or silicon strain-gauge sensor, is a device that converts applied pressure into a small differential voltage using diffused resistors on a silicon diaphragm. The on-chip ASIC conditions this raw signal, applies temperature compensation across the -40 °C to +125 °C range, and normalizes the output so the device produces a near-linear analog voltage directly readable by an MCU ADC. Key features include ±1.5 % maximum pressure accuracy over 0 °C to 85 °C, an ratiometric analog output proportional to a 4.75 V to 5.25 V supply, and a typical response time of 1.0 ms. The 8-DIP through-hole package (10.67 x 10.67 x 12.96 mm) simplifies prototyping and breadboarding, while the integrated calibration eliminates external compensation components. The device also provides ESD protection rated above 1000 V HBM on sensor pins per industry test methods. Typical applications include HVAC pressure monitoring, medical respiratory equipment, weather stations, altimeters, industrial process control, and appliance water-level sensing. Because the output spans nearly the full 0-5 V ADC range of most 5 V microcontrollers, no external amplifier is needed in many designs. The vented gauge reference makes it ideal for applications where barometric compensation is desired, such as portable altimeters and weather instruments. When designing with this part, add a 0.01 µF to 0.1 µF decoupling capacitor close to VDD, and consider a low-pass RC filter on VOUT if the host ADC is sensitive to high-frequency noise. Avoid liquids contacting the silicone gel coating inside the port, and route the supply trace away from switching nodes to preserve the ratiometric accuracy.
MPVZ7025DP - ±3.63 PSI Differential Pressure Sensor, 8-BSOP | NXP
The NXP MPVZ7025DP is an integrated silicon piezoresistive pressure transducer that delivers a calibrated, temperature-compensated analog voltage output proportional to differential pressure. Housed in an 8-BSOP (0.475 inch / 12.06 mm) surface-mount package with dual ports on the same side, the device measures ±3.63 PSI (±25 kPa) of differential pressure and produces an output swing of 0.2 V to 4.7 V from a 5 V supply, making it suitable for direct connection to an ADC without external signal conditioning. On-chip signal conditioning, calibration, and temperature compensation eliminate the need for external compensation networks, and the differential port style (Male, 0.13 inch / 3.3 mm tube, dual same-side) allows convenient plumbing in flow and differential-pressure applications. A board-mount pressure sensor is a transducer that converts applied gas or air pressure into a proportional electrical signal, generally an analog voltage, current (4-20 mA), or digital (I2C/SPI) value. Within the sensor family hierarchy, the MPVZ7025DP sits at: pressure sensor -> board-mount pressure sensor -> piezoresistive pressure sensor -> differential pressure sensor -> MEMS silicon pressure sensor. It belongs to the broader Sensors product category and is used whenever a system must measure the pressure difference between two points rather than absolute pressure referenced to vacuum. Key specifications include ±25 kPa operating pressure range, 0.2 V to 4.7 V analog output swing, on-chip ASIC signal conditioning, and 5 V typical supply. The transducer uses a monolithic silicon diaphragm with implanted piezoresistive bridges laser-trimmed for offset and span, then calibrated over temperature for accuracy. The 8-BSOP Dual Ports Same Side package supports surface-mount assembly and simplifies hose connection for differential flow sensing. Typical applications include HVAC variable-air-volume (VAV) damper control, medical respiration monitoring, industrial flow sensing, altitude and barometric trend instrumentation, and consumer appliance pressure feedback. Its differential port style lets designers reference one side to ambient while measuring on the other, or compare two points in a flow stream. When integrating the MPVZ7025DP, ensure each port connects to a clean, dry, non-corrosive gas source and add a 100 nF decoupling capacitor close to the supply pin. The output is ratiometric with Vcc, so use a stable, low-noise 5 V reference ADC to preserve accuracy across the 0.2 V to 4.7 V output span. This page synthesizes distributor pricing from NXP and authorized partners, drop-in same-package alternatives from the MPXV7025 family, and practical sensor-design notes that go beyond the manufacturer datasheet.

MPVZ7025G6U - ±25kPa Compound Pressure Sensor, 5V, 8-SMD | NXP
The NXP MPVZ7025G6U is an integrated silicon piezoresistive pressure sensor that delivers a calibrated, temperature-compensated analog voltage output proportional to applied pressure. The device measures compound pressure from -25 kPa to +25 kPa (±3.63 PSI) and provides a ratiometric analog output spanning 0.2 V to 4.7 V at 5 V supply, with on-chip signal conditioning, temperature compensation, and factory calibration already applied. Housed in an 8-lead SMD module with a no-port (gel-filled) sensing cavity, the MPVZ7025G6U is part of the MPXV7025 family of monolithic pressure transducers from NXP (formerly Freescale Semiconductor). A pressure sensor is a transducer that converts an applied gas or fluid pressure into a proportional electrical signal. Compound pressure sensors specifically measure both positive (above atmospheric) and negative (vacuum, below atmospheric) pressure relative to a sealed reference, making them ideal for applications where the pressure can swing across atmospheric in either direction. In the broader sensor hierarchy, pressure sensors fall under MEMS (micro-electromechanical systems) -> physical sensors -> sensors. The MPVZ7025G6U's monolithic silicon diaphragm with integrated piezoresistive bridge is the defining technology of this category. Key features include ±25 kPa (±3.63 PSI) compound measurement range, 0.2 V to 4.7 V analog output swing at 5 V VDD, ±5% accuracy across the compensated temperature range, and supply voltage operation from 4.75 V to 5.25 V. Operating temperature range is -40 °C to +125 °C with integrated temperature compensation over 0 °C to 85 °C. The SMD-8 module integrates the sensor die, signal conditioner, and compensation network in a single surface-mount package, eliminating the need for external analog conditioning circuitry. Technically, the device uses a monolithic piezoresistive bridge whose resistance changes with diaphragm deflection. The integrated ASIC amplifies the differential bridge signal, normalizes it across temperature, and scales it to the standardized 0.2 V-4.7 V output. Ratiometric output means the output voltage scales linearly with supply voltage, allowing ADC reference tied to VDD to cancel supply noise automatically. Typical applications include HVAC differential pressure sensing, medical respiratory equipment, industrial process control, altimeters and weather stations, and vacuum monitoring systems. The compound range (-25 kPa to +25 kPa) makes it especially suited to applications where pressure can be above or below ambient. The 8-SMD no-port form factor uses a gel-filled top entry for harsh media compatibility. When designing with this device, follow manufacturer reference designs for input filtering and PCB land pattern geometry. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the supply pin. The output is ratiometric - tie the ADC reference to VDD for automatic noise cancellation. Avoid mechanical stress on the package during board assembly.

MPVZ7025GC6U - 25kPa Pressure Sensor, 0.2-4.7V, 8-SMD | NXP
The NXP Semiconductors MPVZ7025GC6U is an integrated silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation and calibration, supplied in an 8-SMD Module (SM OUTLINE / CASE 98ASB17760C) package with a vertical compound port. It measures differential/gage pressure from -25 kPa to +25 kPa (approximately ±3.63 PSI), produces a ratiometric analog output of 0.2 V to 4.7 V from a 5 V nominal supply, and supports a male 0.13" (3.17 mm) tube pressure port. A piezoresistive pressure sensor is a MEMS device that converts applied mechanical pressure into a proportional electrical signal by exploiting the piezoresistive effect in doped monocrystalline silicon. Within the broader sensor taxonomy, MPVZ7025GC6U is a pressure sensor -> force/pressure transducer -> sensor -> electronic component. The on-chip ASIC performs offset, span and temperature calibration so designers do not need to do software compensation, simplifying firmware in HVAC, medical and consumer applications. Key features include: integrated temperature compensation from 0°C to +85°C, ratiometric analog output that scales with supply voltage (immune to supply ripple as a percentage), automotive-grade qualification suitable for under-hood environments, ±2.5% typical pressure accuracy, and a fast 1 ms typical response time. The 0.2 V to 4.7 V swing across 4.5 V full-scale yields roughly 22.5 mV/kPa nominal sensitivity over the linear region. Technically, the MPVZ7025GC6U uses a monolithic silicon diaphragm with a Wheatstone-bridge piezoresistive network and a BiCMOS signal-conditioning ASIC in the same package. The hermetic vertical port isolates the die from humidity and contamination, and the Sifel port material is chemically compatible with many refrigerants, fuels and water-based media. Calibration trim is performed at the wafer level for offset and span, then a final temperature compensation is applied at package test, giving the user a true drop-in sensor. Typical applications include HVAC variable-air-volume (VAV) controllers, medical respiratory monitors and CPAP airflow metering, industrial process pressure monitoring, fuel and oil pressure monitoring in non-safety automotive systems, and consumer fitness/altitude measurement. The 0-5 V analog output simplifies interface to common 8/10-bit ADCs without external op-amps. When designing with this device, place a 100 nF ceramic bypass capacitor as close as possible to the VCC pin and a 10 µF bulk capacitor for noise immunity. Avoid kinking or sharply bending the input tube; the silicone gel port should not be exposed to abrasive particulates or solvents that attack Sifel.

MPVZ7025GP - ±25kPa Compound Pressure Sensor, 8-SMD | NXP
The NXP MPVZ7025GP is an integrated silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, measuring compound pressure from -25 kPa to +25 kPa (±3.63 PSI) and housed in an 8-SMD gull-wing package with a side-mounted tube port. A pressure sensor is a transducer that converts an applied gas or liquid pressure into a proportional electrical signal. Within the broader component taxonomy, the MPVZ7025GP belongs to the sensor category, specifically piezoresistive MEMS pressure sensors, which sit under force/pressure transducers and ultimately fall within measurement and instrumentation semiconductors. The "GP" suffix indicates a compound (gauge) pressure variant with a side-port tube inlet suitable for through-hole or in-line pneumatic connection, while the chip outputs an analog voltage proportional to differential pressure rather than an absolute vacuum-referenced signal. Key features include a calibrated analog output spanning 0.2 V to 4.7 V from a 5 V supply, on-chip temperature compensation from 0 °C to +85 °C, and a state-of-the-art monolithic signal-conditioned, temperature-compensated and calibrated silicon die. The transducer exhibits high accuracy across its compound range and is supplied fully calibrated, eliminating the need for external trim components in typical applications. The MPVZ7025GP architecture is based on a piezoresistive Wheatstone-bridge implant diffused into a silicon diaphragm. Pressure applied to the diaphragm flexes the silicon, unbalancing the bridge and producing a differential output that is conditioned by on-chip ASIC circuitry and scaled to the 0.2 V-4.7 V output swing. Compared with discrete bridge designs, this integration removes external op-amp chains, simplifies firmware, and improves long-term drift behavior. Typical applications include HVAC differential airflow, respiratory monitoring equipment, process monitoring and control, and appliance pressure sensing. The device is widely deployed in medical ventilators, gas-flow instrumentation, and industrial pneumatic systems where compact, calibrated, side-port pressure sensing is required. When designing with this part, ensure the input supply is well-regulated at 5 V ±0.25 V (4.75 V-5.25 V), place a 0.01 µF decoupling capacitor close to Vs, and isolate the side port from direct water or particulate exposure. Output is ratiometric to the supply, so use the same 5 V reference for ADC conversion to preserve accuracy. This page synthesizes distributor pricing, package-level drop-in alternatives, and practical design notes not found in the manufacturer datasheet, intended to accelerate evaluation and sourcing for engineering teams.
MPX10D - 10 kPa Uncompensated Pressure Sensor | NXP / STMicroelectronics
The NXP / STMicroelectronics MPX10D is a 10 kPa uncompensated silicon piezoresistive pressure sensor packaged in a 4-SIP through-hole module, providing a linear voltage output directly proportional to the applied differential pressure. It delivers a full-scale span of 35 mV at 3 V excitation across a 0 to 10 kPa (0 to 1.45 psi) range with a typical sensitivity of approximately 3.5 mV/kPa. A piezoresistive pressure sensor is a micro-electromechanical device in which a silicon diaphragm with implanted strain gauges converts mechanical pressure into a small differential voltage; uncompensated variants omit on-chip temperature correction and signal conditioning, allowing designers to apply custom amplification, offset trim, and thermal compensation externally. Pressure sensors sit within the broader sensor hierarchy of transducers -> MEMS sensors -> piezoresistive sensors -> signal-conditioned pressure ICs, serving as the lowest-level analog interface between physical pressure and an electronic system. Key features include a differential pressure configuration, 0 to 10 kPa operating range, 35 mV full-scale span at 3 V supply, very low offset drift with temperature, and a standard 4-SIP package with a single pressure port. The MPX10 series is also known under the Motorola legacy part number (the original MPX10 family was introduced by Motorola Semiconductors before the NXP and ST spin-offs) and is widely referenced in medical, industrial, and HVAC designs. The internal architecture uses four piezoresistors arranged in a Wheatstone bridge on a silicon diaphragm; when pressure is applied, the diaphragm deflects, unbalancing the bridge and producing a differential output voltage proportional to the applied pressure. Because the device is uncompensated, external instrumentation amplifiers such as the INA126 or AD620 are typically used to amplify the small 35 mV signal to a usable ADC input range. Typical applications include medical respiratory monitoring (spirometry, CPAP, ventilator breathing circuits), industrial low-pressure measurement (HVAC duct pressure, cleanroom pressure differential, leak detection), altitude and barometric sensing, and process control analog front ends. The differential configuration also makes it well-suited to flow measurement across an orifice. When designing with this device, plan to add external temperature compensation and a low-noise instrumentation amplifier; the 35 mV full-scale signal at 3 V excitation is too small to feed directly into most ADCs without gain. Use a regulated low-noise supply to avoid powering noise coupling into the bridge output. This page synthesizes pricing data from NXP and STMicroelectronics, pin-compatible drop-in alternatives from the MPX10 family (MPX10DP, MPX10G, MPXV10GC6U), and practical design notes not consolidated in the manufacturer datasheet.
MPX10DP - 10kPa Differential Pressure Sensor 35mV | STMicroelectronics
The STMicroelectronics MPX10DP is a 10 kPa uncompensated silicon piezoresistive pressure sensor in a 4-SIP module with a male 0.19 inch (4.93 mm) tube port, providing a linear differential analog output of 0 mV to 35 mV at a 3 V excitation. It belongs to the legacy MPX10 series originally introduced by Motorola and now produced under both NXP Semiconductors and STMicroelectronics branding, serving as the foundational bare-die building block for higher-range MPX2010/MPX2050/MPX2100 family sensors. A piezoresistive pressure sensor is a MEMS device in which a silicon diaphragm with implanted strain gauges changes its Wheatstone-bridge resistance in proportion to applied differential pressure. The MPX10DP operates as a bridge transducer that converts differential pressure into a low-level mV-level voltage, so it sits at the bottom of the signal-conditioning chain - downstream of it are usually instrumentation amplifiers, ADC channels, and microcontroller-based temperature compensation algorithms. As a category, it belongs to the pressure sensor family -> MEMS sensor -> sensor -> transducer hierarchy. Key features include a 0 kPa to 10 kPa (0 to 1.45 PSI) operating range, 35 mV full-scale span at 3 V excitation, differential dual-port tube inlet, and an uncompensated output requiring user-supplied temperature compensation. The 4-SIP through-hole mount with dual axial tubes simplifies pneumatic connection in laboratory, medical, and industrial pressure-sensing assemblies. The device uses a single-axis silicon diaphragm with a four-resistor piezoresistive bridge, so its architecture is intentionally simple to allow OEM calibration and proprietary linearization. Because the output is uncompensated, designers must add a reference-grade op-amp stage (e.g., INA128 or AD8421) and active temperature compensation for production-grade accuracy. Typical applications include low-pressure medical instrumentation (respiratory and spirometry circuits), HVAC differential flow sensing, barometric baseline sensing, industrial pneumatic monitoring, altimeter reference stages, and OEM custom pressure transducers. It is frequently a drop-in pre-cursor to the MPX5010DP integrated pressure sensor family. When designing with this device, the key trade-off is uncompensated output: although it reduces unit cost, the designer must add calibration, temperature compensation, and zero/span trim circuitry, which raises development time. Use a low-drift instrumentation amplifier and a precision voltage reference for the bridge excitation.

MPX10GP - 10kPa Uncompensated Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX10GP is a 10 kPa uncompensated silicon piezoresistive pressure sensor in a 4-SIP through-hole module with a male 0.19" (4.93 mm) tube pressure port. It provides a linear analog voltage output of 0 mV to 35 mV at 3 V excitation over a 0 to 10 kPa (0 to 1.45 PSI) vented gauge pressure range, making it a foundational building block for designers who need to add their own temperature compensation and signal conditioning. A piezoresistive pressure sensor is a MEMS device in which implanted piezoresistors on a silicon diaphragm change resistance when mechanical strain from applied pressure alters the band structure of the silicon. The MPX10GP belongs to the silicon pressure sensor family, which sits within transducers, which in turn sit within the broader sensor hierarchy used for physical-parameter measurement. This uncompensated architecture is the lowest-cost tier of the family; downstream amplification, offset correction, and temperature drift correction must be implemented externally with op-amps and reference sources. Key features of the MPX10GP include an operating pressure range of 0 to 10 kPa (approximately 0 to 1.45 PSI), a full-scale span of 35 mV typical at 3 V DC excitation, and a vented gauge reference that allows absolute atmospheric pressure measurement through a single port. The 4-SIP through-hole package simplifies hand prototyping and breadboard use, while the integrated tube inlet accepts flexible pneumatic tubing for airflow or liquid-level sensing applications. Technically, the sensor is built on a single-element piezoresistive Wheatstone bridge with on-chip trimming, with a sensitivity around 3.5 mV/kPa at 3 V supply. Because the device is uncompensated, designers must characterize offset, span, and temperature coefficient in their own test fixtures and apply corrections in software or analog networks to achieve production-grade accuracy. Typical applications include HVAC air-flow measurement, medical respiratory equipment, water-level tank sensing, barometric reference design, and industrial process control where custom external compensation is acceptable in exchange for low unit cost. Designers building precision instrumentation typically select a higher-tier compensated MPX series part instead. When designing with this device, ensure a stable low-noise 3 V excitation source and use instrumentation amplifiers with low offset drift. The uncompensated nature means PCB layout should keep analog signal traces short and shielded from digital switching noise. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
MPX10GS - 10 kPa Uncompensated Silicon Pressure Sensor | NXP
The NXP MPX10GS is a 10 kPa uncompensated silicon piezoresistive pressure sensor in a 4-SIP module with a side-port tube inlet (0.19 inch / 4.93 mm), delivering a linear analog voltage output of 0 mV to 35 mV at 3V excitation and providing a vented gauge pressure reading of 0 to 1.45 PSI (0 to 10 kPa). This NXP Semiconductors sensor uses a precision silicon strain-gauge bridge that is directly proportional to applied pressure, making it a foundational building block for cost-sensitive pneumatic, medical, and instrumentation designs that add their own compensation and amplification. Background knowledge: A pressure sensor is a transducer that converts an applied pressure force into a measurable electrical signal. Within the broader transducer taxonomy, the MPX10GS sits in the piezoresistive pressure sensor family, which uses the piezoresistive effect in silicon — a change in electrical resistance when mechanical stress is applied. This family sits under the hierarchy pressure sensor -> transducer -> sensor -> electronic component. The MPX10GS is uncompensated, meaning the manufacturer does not calibrate offset, span, or temperature drift; designers must add external op-amps and calibration routines to reach medical or industrial accuracy. Key features of the MPX10GS include 35 mV full-scale span (typical), an operating pressure range from 0 to 1.45 PSI (0 to 10 kPa), vented gauge reference (G suffix on the package style), a 4-SIP through-hole package, and a typical operating temperature range that supports industrial and consumer environments. The device requires only a single 3V DC excitation source and produces a Wheatstone-bridge differential output that scales linearly with pressure, allowing straightforward signal conditioning with instrumentation amplifiers such as the INA125 or INA126. From an architectural standpoint, the MPX10GS die is laser-trimmed to provide tight linearity across its specified pressure range, and the vented gauge configuration means the back side of the die is referenced to ambient pressure through the port tube, simplifying absolute-pressure measurements in atmospheric applications. Designers can implement temperature compensation, offset null, and span calibration using low-cost operational amplifiers or a dedicated mixed-signal microcontroller ADC. Typical applications include low-pressure pneumatic control, HVAC differential-pressure monitoring, medical respiratory and airflow instruments, altimeters and barometric estimation, fluid-level sensing via pressure, and consumer fitness or wearables requiring basic airflow sensing. Industrial 4 mA to 20 mA loop-transmitter front ends also use the MPX10GS as the raw sensing element. When designing with the MPX10GS, plan for external amplification — the 35 mV full-scale span is too low to drive an ADC directly. Add a low-offset, low-noise instrumentation amplifier and a stable 3V excitation regulator. Shield the analog traces from digital switching noise to preserve the small mV-level signal integrity.

MPX12D - 10 kPa Diff Pressure Sensor, 4-SIP | NXP Semiconductors
The NXP Semiconductors MPX12D is a 10 kPa uncompensated silicon piezoresistive differential pressure sensor in a 4-SIP through-hole module. The device produces a linear voltage output of 0 to 55 mV at 3 V excitation, directly proportional to applied differential pressure, with a maximum operating pressure of 1.45 PSI (10 kPa) and proof pressure of 10.88 PSI (75 kPa). The integrated Wheatstone bridge strain gauge delivers a ±5% accuracy specification and supports a single 3 V supply, making the MPX12D a cost-effective transducer for OEM designs that prefer external temperature compensation and signal conditioning. A piezoresistive pressure sensor is a MEMS device in which a silicon diaphragm with an embedded Wheatstone bridge deforms under applied pressure, changing bridge resistance and producing a differential output voltage proportional to pressure. As an uncompensated transducer, the MPX12D exposes the raw bridge outputs so the system designer can apply custom linearization, temperature correction, and amplification in downstream analog circuitry. The MPX12 series sits within the broader taxonomy of pressure sensors -> MEMS sensors -> transducers -> sensors, and serves as a foundational building block in medical, industrial, and HVAC pressure measurement. Key features of the MPX12D include a 0 to 55 mV full-scale output at 3 V supply, ±5% linearity, single-element strain gauge design for predictable compensation, PCB termination, and a female pressure port of 0.136 inch (3.45 mm). The 4-SIP module package provides a robust through-hole mechanical interface with a barbed port for tubing connection. Because the sensor is uncompensated, downstream op-amps such as the MPX2010DP and instrumentation amplifiers are typically required to amplify the millivolt-level output to a usable 0-5 V or 4-20 mA signal. The MPX12D uses NXP's patented silicon shear strain gauge process, in which four piezoresistors are ion-implanted into a single silicon diaphragm. This monolithic single-element design yields excellent long-term stability and predictable thermal behavior compared to multi-element compensated sensors. Designers add external temperature compensation and amplification networks because the raw bridge output varies with temperature - typically a few percent of full scale across 0-85 °C. NXP's MPX2010 and MPX2050 series offer similar packages with higher pressure ranges (up to 50 kPa), allowing scaling within the same design footprint. Typical applications include medical ventilators and respiratory monitoring, HVAC air-flow measurement, industrial process control, barometric pressure sensing, and altitude measurement in portable instrumentation. The differential configuration is well suited to cleanroom pressure drop monitoring and CPAP/BPAP airflow sensing where bidirectional pressure detection is required. When designing with the MPX12D, plan the signal chain around a low-noise instrumentation amplifier (e.g., INA122 or AD620) with gain of 50-100 to scale the 55 mV full-scale output to 2.7-5.5 V. Add a temperature-compensation network using an NTC thermistor or dedicated analog temperature correction to maintain accuracy across 0-70 °C operating range.

MPX12DP - 10kPa Differential Pressure Sensor 4-SIP | NXP
The NXP MPX12DP is a 10 kPa uncompensated silicon piezoresistive differential pressure sensor packaged in a 4-SIP through-hole module with dual axial 0.19" (4.93 mm) tube ports. It delivers a linear analog voltage output directly proportional to applied differential pressure over a 0 to 10 kPa (0 to 1.45 PSI) range, with full-scale span of 35 mV typical (55 mV maximum at 3V excitation) and a sensitivity of 5.5 mV/kPa. A piezoresistive pressure sensor is a MEMS device in which four silicon strain gauges arranged in a Wheatstone bridge are etched into a monolithic silicon diaphragm. When differential pressure deflects the diaphragm, the gauges change resistance and the bridge produces a millivolt-level differential output. Uncompensated sensors like the MPX12 family intentionally omit on-chip calibration, op-amps, and temperature compensation, allowing OEMs to add their own external signal conditioning and temperature-compensation networks at the lowest possible cost. Key features include a 5.5 mV/kPa typical sensitivity, ±5% linearity, 35 mV typical full-scale span, and a 0 to 55 mV output span over a 0 to 3V excitation range. The 4-SIP module mounts vertically on a PCB and accepts two external 4.93 mm tubes for inlet and outlet flow or pressure references. The device operates from -40C to +125C and requires only a stable DC excitation source, a low-offset instrumentation amplifier (typically 2 to 35 gain), and a small calibration EEPROM in the customer signal chain. The MPX12DP silicon die uses bulk micromachined piezoresistors with laser-trimmed bridge resistors for tight span tolerance. Because the raw output is small (millivolts), design attention must focus on low-noise PCB layout, guarding of high-impedance nodes, and a precision low-drift front-end amplifier such as the INA333 or MCP3300D to extract a useful 0 to 5V or 4 to 20 mA industrial signal. Differential sensing makes the part suitable for measuring flow across an orifice, filter pressure drop, or tank-level hydrostatic pressure referenced to atmosphere. Typical applications include HVAC variable-air-volume (VAV) box flow sensing, medical respirators and CPAP blowers, industrial process control differential flow meters, filter saturation detection, and low-pressure laboratory instrumentation. The differential port configuration allows both sides of the sensor to see positive pressure, with the output representing the difference. Through-hole Mounting and a standard 4-SIP footprint simplify hand-soldered prototyping and rugged field installations. Designers should select an instrumentation amplifier with input bias current below 1 nA and a CMRR above 80 dB to preserve the bridge linearity. Place the INA as close as possible to the sensor pins to minimize leakage and thermocouple-induced offsets at the millivolt signal level.

MPX12GP - 10 kPa Uncompensated Pressure Sensor 4-SIP | NXP
The NXP MPX12GP is a 10 kPa uncompensated silicon piezoresistive pressure sensor in a 4-SIP through-hole module with a male 0.19" (4.93 mm) pressure port, specified for vented-gauge measurements and typically sold by STMicroelectronics and NXP/Freescale in the same datasheet family. It delivers a differential analog output of 0 mV to 55 mV at a 3 V supply, providing a linear, low-cost transducer element that designers can pair with their own external temperature-compensation and signal-conditioning networks. The sensor targets 1.45 PSI (10 kPa) full-scale pressure and is part of the legacy MPX10/MPX12 uncompensated family that Motorola introduced and Freescale/NXP later transferred into their own product lines. According to the manufacturer datasheet (MPSD-001), the device is built using a monolithic silicon piezoresistive die and a ported 4-SIP case that simplifies PCB mounting and pneumatic hose attachment. A piezoresistive pressure sensor is a transducer that converts applied mechanical pressure into a proportional change of resistance in four silicon strain gauges arranged in a Wheatstone bridge. The bridge is excited by a constant voltage or current, and the resulting differential output voltage scales linearly with applied pressure. Uncompensated sensors like the MPX12GP expose the raw bridge output, allowing designers to add precision op-amps, temperature-compensation lookup tables, and digital calibration - a trade-off favored in cost-sensitive medical and HVAC designs where full signal-chain integration is acceptable. The hierarchy is: pressure sensor -> transducer -> sensor -> electronic component. The MPX12GP sits at the uncompensated, low-cost end of this hierarchy, with compensated and amplified siblings (e.g. MPX4115A, MPX5700) providing higher-level outputs at higher cost. Key specifications include a 10 kPa (1.45 PSI) full-scale pressure range, 0 mV to 55 mV output span at 3 V excitation, ±0.5% linearity, and an operating temperature range of -40 °C to +125 °C. The 4-SIP package style (Case 344B-01) provides a single axial pressure port and four through-hole pins that align 1:1 with the MPX10GP, MPX12DP, and MPX12GP variants. Because the device is uncompensated, designers must characterize the offset, span, and temperature coefficient of the bridge externally. Typical applications include medical spirometry, respiratory monitoring, HVAC duct pressure sensing, altimeters, and low-pressure process instrumentation. The wide operating temperature and simple port geometry also support industrial pneumatic sensing where calibrated offset correction is acceptable. A key design consideration is that uncompensated output requires a low-drift instrumentation amplifier (such as an AD620 or INA128) and a temperature-compensation network. A 1 mA constant-current excitation source will minimize span drift versus temperature compared to a fixed-voltage supply, and a 5th-order polynomial or a 2D lookup table in the host MCU will remove residual non-linearity. This page synthesizes distributor pricing, pin-compatible drop-in alternatives, and practical signal-conditioning notes that go beyond what is published in the bare manufacturer datasheet - making it directly useful to design engineers evaluating pressure-sensing architectures.
MPX2010D - 10kPa Differential Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX2010D is a silicon piezoresistive differential pressure sensor with a 10 kPa (1.45 PSI) full-scale range, housed in a 4-SIP through-hole module (Case 344-15). It delivers a linear analog output from 0 mV to 25 mV at a 10V excitation supply, with on-chip laser-trimmed span and offset calibration plus integrated temperature compensation over 0C to +85C. A piezoresistive pressure sensor is a transducer that converts applied gas or liquid differential pressure into a proportional electrical signal by exploiting the piezoresistive effect in doped silicon. Within the broader hierarchy, the MPX2010D is classified as a MEMS pressure sensor, then as a pressure transducer, then as a signal-conditioning sensor, and ultimately as an integrated semiconductor component. Compared to ceramic capacitive or strain-gauge bridge sensors, piezoresistive silicon sensors offer higher sensitivity in a smaller die, but require a stable excitation voltage and are typically limited to lower pressure ranges. Key features include a 10 kPa full-scale pressure range with differential (Port 1 vs Port 2) measurement topology, 2.5 mV/kPa nominal sensitivity, 0.1% linearity over the compensated range, and an operating temperature range of 0C to +85C. The monolithic silicon diaphragm integrates the strain gauge and thin-film resistor network on-chip, while the uncompensated family cousin MPX2010GP (Case 344B-01) shares the same die but ships un-calibrated for cost-sensitive designs. The MPX2010D uses a four-arm Wheatstone piezoresistive bridge diffused into a single silicon diaphragm. When pressure is applied across Ports 1 and 2, the diaphragm flexes and unbalances the bridge proportionally to the differential pressure. Laser trimming of on-chip resistors calibrates span and offset, and on-chip thin-film resistors implement first-order temperature compensation, removing the need for external compensation networks in most designs. Typical applications include medical respiratory monitoring (spirometers, ventilators), HVAC airflow and differential pressure measurement, industrial process control, altimeters and barometric instrumentation, and portable blood-pressure cuffs. Designers select this part when a calibrated, temperature-compensated, low-pressure differential measurement is required without external signal conditioning. When designing with the MPX2010D, provide a stable low-noise 10V excitation supply and a low-offset instrumentation amplifier such as the INA128 or AD620 to scale the 25 mV full-scale output to a usable 0-5V or 4-20 mA signal. Use anti-aliasing filtering between the sensor output and ADC, and isolate mechanical stress on the SIP package leads from the sensing ports to prevent PCB-induced offset drift.

MPX2010DP - 10 kPa Differential Pressure Sensor | NXP/STMicro
The NXP MPX2010DP is a 10 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor delivering a linear voltage output directly proportional to applied differential pressure. Housed in a 4-SIP module with dual 0.19 inch (4.93 mm) tube ports, it provides a full-scale span of 25 mV at 10 V excitation and is intended for non-corrosive gas or dry air media. A piezoresistive pressure sensor is a solid-state transducer whose Wheatstone-bridge strain gauges diffused into a silicon diaphragm convert mechanical strain into a proportional millivolt-level voltage output. Within the broader transducer taxonomy, this device sits at: piezoresistive sensor -> MEMS pressure sensor -> pressure transducer -> sensor. The on-chip thin-film resistor network delivers a temperature-compensated, calibrated output that simplifies the signal-chain by removing the need for external compensation circuitry in many designs. Key features include 0 to 10 kPa (0 to 1.45 PSI) differential pressure range, 25 mV typical full-scale span at 10 V supply, ±0.05% linearity, ±0.1% to ±2.5% temperature compensation across 0 to 85 °C, and a fast 1.0 ms response time. The 4-SIP through-hole package aligns the dual pressure ports along the sensor axis and supports pressures applied via flexible tubing up to 75 kPa maximum overpressure and 200 kPa burst pressure. According to the NXP product overview, the device operates from -40 °C to +125 °C, making it suitable for industrial and consumer environments. Typical applications include HVAC air-flow monitoring, medical respirators and ventilators, barometric altimeters, industrial process control loops, level detection in sealed containers, and water-column altitude measurement. The dual-port differential topology allows reference-pressure measurement, eliminating barometric drift in measurements where gauge pressure is converted to absolute flow. When designing with the MPX2010DP, place the device in a region of stable ambient temperature and isolate the ports from condensation; use a differential amplifier (e.g., INA125 or equivalent instrumentation amp) to bring the 25 mV span up to ADC-friendly levels. Bridging the result with a low-offset, low-noise op-amp preserves the calibrated linearity across the full temperature range. The MPX2010, MPXV2010G and MPXM2010 series provide accurate and linear output proportional to applied pressure, ideal for OEM system designs.

MPX2010GP - 10 kPa Vented Gauge Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX2010GP is a 10 kPa (1.45 PSI) silicon piezoresistive pressure sensor in a 4-lead SIP module (Case 344B-01) with a vented gauge male port. It delivers a linear voltage output of 0 mV to 25 mV at 10 V excitation, directly proportional to applied pressure, with on-chip temperature compensation and calibration. A pressure sensor is a transducer that converts an applied gas or fluid pressure into a proportional electrical signal. Pressure sensors fit into the sensor hierarchy as follows: pressure sensor -> force/pressure transducer -> MEMS sensor -> semiconductor device. Within this hierarchy, piezoresistive sensors use a strained silicon diaphragm whose resistance changes with mechanical deformation; signal-conditioning circuitry converts this Wheatstone-bridge change into a millivolt-level voltage output that downstream amplifiers can scale to 0-5 V or 4-20 mA. The MPX2010GP uses a single monolithic silicon diaphragm with an integrated strain gauge and thin-film resistor network. On-chip temperature compensation holds sensitivity within tight limits across the operating range, removing the need for external thermistor networks. The device operates over a -40 C to +125 C range and is specified for 0 to 10 kPa differential or gauge pressure, making it suitable for low-pressure medical, HVAC, and instrumentation uses. The vented gauge port references the back side to ambient pressure, eliminating vacuum-pump calibration. Typical applications include medical respiration monitors, HVAC variable-air-volume (VAV) controllers, industrial process instrumentation, altimeters, and low-pressure laboratory measurement. The 25 mV full-scale output requires a low-noise instrumentation amplifier (INA, AD620-class) to drive an ADC. The MPX2010GP series remains a workhorse for low-pressure designs and is widely second-sourced. When designing with this device, route the high-impedance mV signal on a guarded, short trace and add RC low-pass filtering at the amplifier input to suppress RF rectification. Avoid mechanical stress on the plastic port during PCB assembly - the silicone gel isolation only protects the die from chemical and thermal attack, not from mounting force.

MPX2010GS - 10 kPa Gauge Pressure Sensor | NXP | SIP-4
The NXP MPX2010GS is a 10 kPa (1.45 psi) on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor packaged in a 4-SIP module with a 0.19" (4.93 mm) male tube vented-gauge port. It delivers a Wheatstone-bridge analog output spanning 0 mV to 25 mV at 10 V excitation and operates from a 10 V to 16 V supply. The series translates applied pressure into a highly linear, calibrated voltage for direct interface with instrumentation amplifiers and microcontrollers with on-board ADCs. A piezoresistive pressure sensor is a transducer whose conversion of mechanical pressure into an electrical signal relies on a silicon diaphragm embedded with diffused Wheatstone-bridge resistors; when pressure deflects the diaphragm, the bridge imbalance produces a differential output proportional to the applied pressure. The MPX2010GS belongs to the board-mount pressure-sensor family within the broader transducer (sensor -> pressure sensor -> piezoresistive sensor -> gauge pressure sensor -> silicon pressure sensor) taxonomy and is commonly used wherever a small, linear, temperature-stabilized pressure-to-voltage conversion is required. Key differentiating specifications include an operating pressure range of 0 to 10 kPa (0 to 1.45 psi), an output of 0 mV to 25 mV at 10 V, a Wheatstone-bridge analog output type, vented-gauge pressure type referenced to atmosphere, on-chip temperature compensation and calibration, and a 10 V to 16 V supply range. The integrated signal conditioning, calibration, and temperature compensation eliminate external compensation networks and reduce BOM count. At its core, the MPX2010GS uses a single-element piezoresistive die laser-trimmed for span and offset, with on-chip compensation networks (resistors) flat across the 0 to 85 C operating range. The hermetic SIP-4 housing isolates the die from ambient humidity and provides a barbed tube port for pneumatic connection, with a vent port to atmosphere providing gauge (vs. absolute or differential) reference. Compared with uncompensated bare-die sensors, the integrated compensation substantially reduces system-level drift error. Typical applications include medical respirators and ventilators, HVAC variable-air-volume (VAV) controllers, industrial process controllers, barometric/altimeter instrumentation, level measurement, and consumer appliances such as washing-machine water-level sensors. The 10 kPa range suits low-pressure medical and HVAC use cases where barometric noise would otherwise swamp a higher-range transducer. When designing with the MPX2010GS, place an instrumentation amplifier (e.g., INA125, AD620, or NXP MPXAZ5010 interface) directly at the Wheatstone output to convert the millivolt bridge signal to a usable 0-5 V or 4-20 mA signal. Use a stable, low-noise excitation source (10 V typical) because sensor span scales linearly with excitation; noise and drift on the supply will be reflected in the output. Apply a bypass capacitor near the supply pin.

MPX2010GSX - 10kPa Pressure Sensor, 4-SIP, STMicroelectronics
The STMicroelectronics MPX2010GSX is a silicon piezoresistive pressure sensor providing a linear voltage output of 0 mV to 25 mV at 10 kPa (1.45 PSI) full-scale span, housed in a 4-SIP through-hole module with a 0.19" (4.92 mm) tube port for vented gauge measurement. The monolithic silicon diaphragm integrates strain-gauge and thin-film resistor networks on-chip, laser-trimmed for precise span, offset calibration and temperature compensation across 0°C to +85°C. Pressure sensors like the MPX2010GSX are transducers that convert an applied pressure into a proportional electrical signal. Within the broader sensor hierarchy they belong to MEMS (Micro-Electro-Mechanical Systems) devices, and more specifically to piezoresistive pressure sensors - a category that uses strain-induced resistance changes in silicon to produce a Wheatstone-bridge output voltage. Unlike capacitive or optical pressure sensors, piezoresistive designs offer simple excitation (10 V typical), high linearity, and ratiometric output ideal for low-pressure medical and instrumentation applications. Key features include 25 mV full-scale span at 10 V excitation, 0.45% linearity typical, 1.0 mV/kPa sensitivity, on-chip temperature compensation from 0°C to +85°C, and ratiometric output proportional to supply voltage. The 4-SIP package with axial tube port simplifies pneumatic interface, while the through-hole mounting provides robust mechanical retention on the PCB. The MPX2010GSX uses a single monolithic silicon diaphragm with an integrated four-resistor Wheatstone strain-gauge bridge. Laser-trimmed resistors calibrate span and offset at room temperature, with additional thin-film compensation networks maintaining accuracy across the 0°C to +85°C operating range. Excitation at 10 V DC produces a ratiometric output that scales linearly with supply, simplifying ADC interface design. Typical applications include medical respiratory monitoring (spirometers, ventilators), HVAC airflow sensing, industrial process control, and altimeter/barometric reference designs where the 0-10 kPa gauge range matches inhalation flow or low-differential process pressures. When designing with this device, ensure a stable low-noise 10 V excitation supply; supply ripple directly couples into the output. The 0.19" tube port must be sealed against contamination and moisture, and the through-hole pins require strain relief if the pneumatic line applies mechanical load. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers shorten the selection and qualification cycle for 10 kPa vented-gauge pressure sensing.
MPX2050D - 50 kPa Differential Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX2050D is a 50 kPa (7.25 PSI) differential piezoresistive silicon pressure sensor in a 4-lead SIP (Single In-line Package) module, providing a highly accurate and linear voltage output directly proportional to the applied pressure. The device integrates a monolithic silicon diaphragm, on-chip strain gauge, thin-film resistor network, and laser-trimmed span/offset calibration, with 0 mV to 40 mV output swing across the full pressure range when excited with 10 V DC. The differential configuration measures the pressure difference between two inlet ports, suitable for applications where gauge-like measurements are needed without atmospheric reference. A piezoresistive pressure sensor is a MEMS (Micro-Electro-Mechanical Systems) device that exploits the piezoresistive effect in silicon—where applied mechanical stress alters the electrical resistance of implanted resistors—to convert pressure into a measurable voltage. The MPX2050D is part of the broader transducer family hierarchy: pressure sensor → pressure transducer → sensor → electronic component. Its on-chip temperature compensation eliminates the need for external correction networks, simplifying analog signal chain design. Key features include a 0–50 kPa operating range, 0.5% typical linearity, 0.45 mV/kPa typical sensitivity at 10 V excitation, ±0.05% to ±0.2% accuracy across 0–85°C, and a 5 kHz response time. The temperature-compensated output spans −40°C to +125°C, with the laser-trimmed resistors calibrating both span and offset during manufacture. The 4-SIP package provides port access on the inlet side for differential measurement. The sensor uses a Wheatstone-bridge arrangement of piezoresistors diffused into the silicon diaphragm; deflection under pressure unbalances the bridge, producing a differential output voltage. Laser trimming during wafer-level test sets span and offset, while integrated thin-film resistors implement first-order temperature compensation of both span and offset across the operating range. Typical applications include HVAC differential pressure monitoring, medical respiratory equipment, industrial process control, altimeters and variometers, and level measurement in sealed tanks. Designers favor the MPX2050D for its calibrated, linear mV output that interfaces directly with instrumentation amplifiers. When designing with this part, use a low-noise instrumentation amplifier such as the INA125 or INA128 to amplify the 40 mV full-scale output to a usable ADC range. Apply a regulated 10 V excitation to maintain calibration accuracy. Note that the differential port configuration means the sensor measures ΔP between two inlets—do not use it for absolute pressure measurements.
MPX2050GP - 50 kPa Vented Gauge Pressure Sensor | NXP / STMicro
The NXP (formerly Motorola/Freescale, now also STMicro) MPX2050GP is a 50 kPa (7.25 PSI) on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor in a 4-SIP through-hole module with a male 0.19" (4.93 mm) tube port. It delivers a highly linear 0 mV to 40 mV differential analog output at 10 V excitation, making it a classic transducer for medical and HVAC instrumentation. The single monolithic silicon diaphragm integrates a strain gauge and a thin-film resistor network, laser-trimmed for precise span, offset calibration, and temperature compensation across 0C to 85C. A pressure sensor (or pressure transducer) is a device that converts an applied pressure into a measurable electrical signal. Piezoresistive sensors achieve this by exploiting the change in silicon resistance when mechanical strain is applied to an integrated diaphragm. Within the broader sensor hierarchy, the MPX2050GP sits under MEMS sensors -> pressure sensors -> piezoresistive transducers -> board-mount sensor modules. This category is essential whenever a system must monitor fluid or gas pressure for safety, control, or measurement purposes, and analog-output parts like the MPX2050GP remain preferred when interfacing with legacy analog front-ends, instrumentation amplifiers, or microcontroller ADCs. Key features of the MPX2050GP include 0 to 50 kPa (0 to 7.25 PSI) gauge measurement, vented gauge reference for absolute-vs-differential applications, 0 to 40 mV full-scale span (typ) at 10 V supply, low offset drift over 0 to 85C, and a 4-pin unibody SIP package that mounts directly onto a PCB or in-line tubing manifold. The vented gauge configuration allows the back side of the diaphragm to sense atmospheric pressure through the port, simplifying medical and barometric-style designs. The device uses a piezoresistive Wheatstone bridge on the silicon die; laser trimming during manufacture calibrates both offset and span, eliminating most external compensation components. Typical full-scale output is 40 mV at 10 V excitation (4 mV/V), linearity is ~0.05% to 0.1% of full scale, and pressure hysteresis is below 0.1% across the operating range. Typical applications include medical respiratory monitors, HVAC air-flow and filter monitoring, industrial process control, barometric reference sensing, and altimeter/barometer modules. The 4 mV/V sensitivity makes it well-suited to direct ADC input after a low-noise instrumentation amplifier. When designing with this part, pay attention to input excitation noise: a clean, low-noise 10 V reference (or regulated supply) is required because any ripple couples directly into the output. Mount the SIP module mechanically to avoid stress on the pressure port and use a sealed manifold for liquids.

MPX2053D - 50kPa Differential Pressure Sensor 4-SIP | STMicroelectronics
The STMicroelectronics MPX2053D is a 50 kPa on-chip temperature compensated and calibrated silicon piezoresistive differential pressure sensor that delivers a linear voltage output directly proportional to applied pressure. The part provides 0 mV to 40 mV full-scale output (at 10 V excitation) across a differential pressure range of 0 kPa to 50 kPa (0 PSI to 7.25 PSI), packaged in a 4-lead Unibody SIP module measuring 15.56 mm x 15.56 mm x 5.33 mm with 2.54 mm lead pitch. A piezoresistive pressure sensor is a MEMS device that converts mechanical pressure into an electrical signal by exploiting the piezoresistive effect in silicon, where strain-induced changes in the silicon crystal lattice alter resistivity. The single monolithic silicon diaphragm integrates the strain gauge and thin-film resistor network on-chip. This architecture falls within the broader hierarchy of: pressure sensor -> transducer -> sensor -> electronic component. Temperature compensation and laser-trimmed span/offset calibration eliminate the need for external signal conditioning in many low-precision applications. Key features include on-chip temperature compensation across 0 to 85 C, laser-trimmed offset and span calibration, a differential pressure configuration that rejects common-mode pressure, ratiometric analog output proportional to supply voltage, and a robust unibody plastic package rated for harsh-environment media when fitted with a port adapter. The chip is laser trimmed for precise span and offset calibration and temperature compensation. Typical applications include HVAC airflow monitoring, medical respiratory instrumentation, industrial process control, altimeters and barometers, and pneumatic system monitoring. The differential configuration is particularly useful where both sides of the diaphragm are exposed to measured media rather than atmosphere. When designing with this device, designers must provide a stable 10 V DC excitation supply (typical) and an instrumentation amplifier with high common-mode rejection ratio to extract the low-milliVolt signal cleanly. Port orientation and tubing must be selected to avoid condensation or media contamination of the sensing die.
