MPVZ4006G6U - 0-6kPa Vented Gauge Pressure Sensor, 8-SMD | NXP
The NXP (formerly Freescale) MPVZ4006G6U is a monolithic piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, housed in an 8-pin SMD module (SOP-8 with port). It measures vented gauge pressure from 0 kPa to 6 kPa (0 to 0.87 PSI) and provides a ratiometric analog output from approximately 0.3 V to 4.6 V at 5 V supply. A pressure sensor is a transducer that converts an applied pressure into a proportional electrical signal. Piezoresistive sensors use strain gauges diffused into a silicon diaphragm; when pressure deflects the diaphragm, the embedded resistors change value, producing a differential output. On-chip signal conditioning, temperature compensation, and calibration eliminate the need for external compensation networks, allowing the analog output to be read directly into an ADC input of a microcontroller. Within the broader sensor hierarchy, the MPVZ4006G6U belongs to the piezoresistive silicon pressure sensor family, which sits inside MEMS sensors, which sit inside sensors and transducers. Key features include a pressure range of 0 kPa to 6 kPa (vented gauge), a ratiometric analog output (0.3 V to 4.6 V at 5 V supply), 5 V supply operation (4.75 V to 5.25 V), and high accuracy with on-chip calibration. The 8-SMD module package with a single horizontal port simplifies pneumatic interface via a small tube or sealed gasket. The vented gauge reference uses a rear-side vent path to atmospheric pressure, eliminating the need for external gauge reference plumbing. Technically, the device uses advanced micromachining plus thin-film metallization plus bipolar semiconductor processing. The piezoresistive bridge is laser-trimmed during calibration to null offset and span errors at room temperature, with residual errors characterized over the -10 °C to +85 °C operating range. The ratiometric output scales with supply voltage, which means ADC readings performed with the same rail as VDD remain accurate across supply variation. Typical applications include medical respiratory monitoring (CPAP, spirometry), HVAC variable-air-volume controls, appliance pressure sensing (water level, vacuum cleaner suction), industrial process monitoring, weather stations, and consumer fitness equipment. Its low pressure range and vented gauge reference make it well suited to differential pressure measurement across flow restrictors. When designing with this part, place the sensor port in a stable mechanical environment to avoid pressure transients from tubing resonance. Use the same 5 V rail for the sensor and the ADC reference to take advantage of ratiometric cancellation of supply noise, and decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the supply pin.

MPVZ4006G7U - 6kPa Vented Gauge Pressure Sensor, 0.3-4.6V | NXP
The NXP Semiconductors MPVZ4006G7U is an integrated silicon pressure sensor providing a 0.3V to 4.6V analog output for 0 to 6 kPa (0 to 0.87 PSI) vented gauge pressure, housed in a through-hole mounted 8-pin DIP module. On-chip signal conditioning, temperature compensation, and calibration eliminate the need for external compensation circuitry. What is a piezoresistive pressure sensor? It is a MEMS device in which microscopic silicon diaphragms deform under applied pressure; embedded piezoresistors change resistance proportionally, which is then read by an on-chip Wheatstone bridge and offset/temperature compensation network. Within the broader taxonomy, the MPVZ4006G7U sits at: pressure sensor -> MEMS sensor -> sensor IC -> semiconductor. These signal-conditioned analog-output sensors are designed to interface directly with microcontroller A/D inputs, simplifying firmware and BOM. Key features include a calibrated pressure range of 0 kPa to 6 kPa, supply voltage of 4.75V to 5.25V, output span of 0.3V to 4.6V (5% to 95% of 5V supply), accuracy of ±1.5% over 0°C to 85°C, and on-chip temperature compensation. The 8-DIP through-hole package supports robust PCB mounting with port-style pressure inlet. The transducer uses advanced MEMS micromachining with a monolithic silicon die combining the mechanical sensing diaphragm and bipolar signal-conditioning ASIC in a single package. The result is a ratiometric analog voltage output (proportional to VDD) that cancels supply-voltage variation when read by an ADC using the same 5V rail as its reference, yielding high effective accuracy without precision voltage references. Typical applications include HVAC airflow sensing, respirator/CPAP airflow monitoring, water-level/level-pressure sensing, weather stations, and industrial pneumatic monitoring. In consumer health devices, the small size and signal-conditioned output shorten design cycles significantly. When designing with this part, use a low-pass RC filter on the output to attenuate high-frequency noise before the ADC, and provide adequate decoupling (100 nF plus 1 µF) near VDD. Avoid exposing the port to condensing moisture or particulate contamination without an inlet filter membrane.

MPVZ4006GW7U174 - 6kPa Pressure Sensor, 0.3-4.6V | NXP
The NXP MPVZ4006GW7U174 is an integrated silicon piezoresistive pressure sensor with on-chip signal conditioning, delivering a ratiometric analog output of 0.3 V to 4.6 V proportional to applied pressure. The device measures differential/gauge pressure from 0.87 psi (6 kPa) full-scale across a calibrated temperature range, and is housed in an 8-DIP through-hole module with a 0.22 inch (5.59 mm) tube port for pneumatic connection. The MPVZ4006GW7U174 is part of the MPVZ4006 series, originally introduced by Freescale Semiconductor and now owned by NXP after the company acquisition. What is a pressure sensor? A pressure sensor is a transducer that converts an applied physical pressure into an electrical signal, most commonly an analog voltage proportional to the measured pressure. Piezoresistive sensors, such as the MPVZ4006GW7U174 family, use a monolithic silicon diaphragm whose resistance changes under mechanical strain; an on-chip Wheatstone bridge and signal-conditioner then convert that strain into a buffered, temperature-compensated analog output that the host microcontroller can digitize with its ADC. Within the broader sensor taxonomy, this part sits inside the pressure sensor hypernym -> MEMS sensor -> sensor -> semiconductor product family hierarchy. Key features of the MPVZ4006GW7U174 include a 5.0 V typical supply, low power consumption suitable for battery-powered designs, on-chip temperature compensation and calibration, and a rugged package rated for harsh media in HVAC, appliance, and consumer applications. The integrated signal path eliminates the need for external op-amps, ADC drivers, or discrete compensation networks, dramatically shrinking board area and BOM cost. Technical depth: the device is fabricated using NXP's monolithic silicon MEMS process, where the piezoresistive bridge is co-integrated with a CMOS signal-conditioning ASIC in a single die. This co-integration enables the high accuracy (±1.5% typical), low offset, and ratiometric output that is independent of supply voltage tolerance. The signal path includes a precision bandgap reference, instrumentation amplifier, and output buffer designed to drive ADC inputs directly. Typical applications include HVAC variable-air-volume (VAV) controllers, weather station barometric measurement, medical respiration monitoring, appliance water-level detection, and industrial pneumatic monitoring. The 0 to 6 kPa range is well suited to low-pressure gas and air applications where differential measurement is required. Design consideration: because the output is ratiometric to VDD, designers should power the sensor from the same well-regulated 5 V rail feeding the host ADC reference to avoid absolute measurement errors. Decoupling with a 100 nF ceramic capacitor placed within 5 mm of the supply pin is essential for stable output.

The NXP MPVZ5004G6T1 is a state-of-the-art monolithic silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, designed for a 0 to 3.92 kPa (0 to 0.57 PSI) vented gauge pressure range. It delivers a ratiometric analog output from 1 V to 4.9 V at a 5 V supply, housed in an 8-SMD module with surface-mount lead style. The vented gauge reference makes it ideal for applications requiring barometric or relative pressure sensing. A piezoresistive transducer is a MEMS device in which implanted strain gauges on a silicon diaphragm change resistance when deflected by applied pressure; an integrating electronics device with on-chip conditioning, temperature compensation, and calibration amplifies and linearizes the raw bridge output into a useable analog voltage. Pressure sensors sit at the bottom of the sensor signal chain (sensor -> signal conditioner -> ADC -> microcontroller), and the MPVZ5004G6T1 is an integrated transducer whose calibration eliminates the need for external analog trimming by the user. Key features include an operating pressure span of 0 to 3.92 kPa, an output voltage span of 1 V to 4.9 V at 5 V supply, a sensitivity of approximately 1 V/kPa, and a 5 V typical supply voltage (5 V max 5.25 V). The MPVZ5004G6T1 is part of the MPxx5004 family (MPXV5004G and MPVZ5004G series), built with thin-film metallization and bipolar semiconductor processing. The transducer combines an implanted strain gauge with advanced micromachining techniques, thin-film metallization, and bipolar processing to deliver a temperature-compensated, calibrated analog voltage directly to a microcontroller ADC. A vented gauge reference port at the package rear exposes the back side of the diaphragm to ambient atmosphere, so output reflects the differential pressure between the front port and the local atmosphere. Typical applications include HVAC variable-air-volume (VAV) controls, weather station barometric pressure monitoring, respiratory and spirometry equipment, medical monitoring devices, altitude estimation in portable electronics, and small appliance pressure feedback. The vented gauge topology makes it directly suitable where atmospheric reference is desired. When designing with this device, place a 0.1 uF decoupling capacitor as close as possible to the supply pin and keep the analog output trace short to minimize noise pickup. Vented gauge sensors must be exposed to ambient pressure through a clean hydrophobic vent, and the inlet port must be protected from contamination and direct water exposure.
MPVZ5004G6U - 3.92kPa Vented Gauge Pressure Sensor 8-SMD | ST
The STMicroelectronics MPVZ5004G6U is a state-of-the-art monolithic silicon piezoresistive pressure sensor that delivers a calibrated, temperature-compensated analog output proportional to applied differential pressure. It is rated for 0.57 PSI (3.92 kPa) full-scale span using a vented gauge reference, with output swing from 1 V to 4.9 V at 5 V supply, all housed in an 8-SMD surface-mount module. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a micro-electromechanical (MEMS) device in which implanted strain gauges on a silicon diaphragm change resistance when the diaphragm flexes under pressure; this resistance change is conditioned on-chip into a high-level analog voltage. Within the broader sensor hierarchy, this part sits under board-mount pressure sensors -> MEMS sensors -> sensors -> semiconductors, and is a member of the MPxx5004 family alongside MPXV5004G and MP3V5004 variants. Key features include an integrated signal conditioner and temperature compensation, 0 to 85 degrees Celsius compensated range, ratiometric analog output that scales with supply voltage, and a fast 1 ms typical response time. The on-chip bipolar signal chain eliminates the need for external amplification, ADC buffering, or software temperature correction, dramatically simplifying host firmware and analog front-end design. The MPVZ5004G6U uses a vented gauge reference (a top-side vent port exposes the back of the die to ambient atmospheric pressure), which means the device measures pressure relative to local barometric conditions. This is critical for weather-independent absolute measurements and simplifies sealing at the manifold interface. Typical applications include HVAC variable-air-volume (VAV) controllers, respiratory / sleep-apnea airflow monitoring, altimetry and barometric trend instrumentation, industrial process controllers, and portable weather stations. The wide 5 V single-supply operation makes it a natural fit for 3.3 V / 5 V microcontroller analog input rails. When designing with this part, place 100 nF + 1 uF decoupling close to the supply pin and route the analog output with a guard trace to keep digital switching noise below the 1 percent FS noise floor. Note that the vented-gauge topology is not suitable for sealed, watertight enclosures without a dedicated vent tube.

The sensor integrates a thin-film metal strain gauge on a micromachined silicon diaphragm with bipolar signal-conditioning circuitry, producing a high-level analog output proportional to applied pressure. A piezoresistive pressure sensor is a transducer in which strain gauges diffused into a silicon diaphragm change resistance under mechanical stress, producing an electrical signal proportional to applied pressure. The MPVZ5004G7U belongs to the MPxx5004 family of integrated pressure sensors, sitting in the hierarchy: pressure transducer -> piezoresistive sensor -> signal-conditioned pressure sensor IC -> MEMS sensor -> semiconductor. Compared with bare MEMS dies, integrated parts like this combine the sense element, amplifier, and trim network on one chip, eliminating most external components in a typical circuit. Key features include a ratiometric 5 V supply operation, 1.0 V to 4.9 V analog output swing across the calibrated pressure range, integrated temperature compensation from 0C to 85C, on-chip calibration, and a vented gauge port that references the back side of the diaphragm to ambient. The DIP-8 module is designed for through-hole mounting with an axial pressure port and includes a gel-protected die for moisture resistance in non-condensing environments. The architecture uses bipolar signal conditioning with laser-trimmed resistors to calibrate offset and full-scale at the factory, so end users do not need to perform extensive external compensation. The device exhibits typical pressure linearity within +/-1.5% of full-scale span and is designed for smooth monotonic output over the entire pressure range. Typical applications include medical respiratory equipment, HVAC pressure monitoring, air-flow and differential-pressure sensing, appliance vacuum sensing, and other low-pressure instrumentation where a calibrated analog output is preferred over a raw bridge output. When designing with the MPVZ5004G7U, decouple the supply pin with a 0.1 uF ceramic capacitor placed close to the device. Because the output is ratiometric, connect the ADC reference to the same 5 V rail as the sensor to preserve accuracy. Avoid exposing the gel-coated port to condensing humidity or direct water contact.

It measures vented gauge pressure from 0 to 3.92 kPa (0 to 0.57 PSI) and provides a ratiometric analog output voltage spanning 1 V to 4.9 V at a 5 V supply. The device is designed for applications employing microcontrollers or microprocessors with A/D inputs, integrating advanced micromachining, thin-film metallization, and bipolar semiconductor processing on a single die. A piezoresistive pressure sensor is a transducer that converts applied pressure into a proportional electrical signal by exploiting the piezoresistive effect in doped silicon strain gauges. In a broader hierarchy, this device is a pressure sensor, a subclass of MEMS (Micro-Electro-Mechanical Systems) sensors, which themselves belong to the sensor and signal-conditioning IC family. Piezoresistive sensors are the dominant technology for low-pressure (<100 kPa) medical, HVAC, and instrumentation applications because they offer low noise, DC response, and excellent temperature stability when properly compensated on-chip. Key features include a 1 V to 4.9 V ratiometric analog output (4.9 V / 5 V span), 0 to 3.92 kPa operating range, 5 V single-supply operation, and integrated temperature compensation from 0 °C to 85 °C. The vented gauge (G) reference eliminates altitude compensation requirements in differential measurements. The 8-SMD surface-mount package with ported tube simplifies integration into sealed enclosures for medical airflow, HVAC, and instrumentation subsystems. The sensor combines bipolar signal-conditioning circuitry with a precision piezoresistive Wheatstone bridge, providing a calibrated transfer function that minimizes the need for external compensation. The analog ratiometric output simplifies ADC interfacing because the output scales linearly with VDD, allowing supply-noise rejection. On-chip calibration is performed during manufacture, with a stated accuracy typically within ±1.5 %VFSS over the compensated temperature range. Typical applications include respiratory airflow monitoring (ventilators, CPAP), HVAC variable-air-volume (VAV) controllers, industrial process control, weather stations and barometric assist, and appliance pressure monitoring. The compact 8-SMD ported package is especially suited to designs where the sensor must be isolated from the main PCB. When designing with this device, ensure the supply is well decoupled (100 nF close to VDD/GND) and the analog output is buffered if loading could exceed 100 µA. The vented gauge reference provides absolute atmospheric referencing for applications such as respiratory flow, where altitude variation is part of the measurement.

MPVZ5004GW7U - 3.92kPa Pressure Sensor, 5V, SOP-8 | NXP
The NXP MPVZ5004GW7U is a monolithic silicon piezoresistive pressure sensor housed in an 8-pin DIP/SOP module that delivers a conditioned analog output of approximately 1 V to 4.9 V over a 0 to 3.92 kPa (0.57 psi) vented gauge pressure range. The device integrates on-chip signal conditioning, temperature compensation, and calibration, producing a ratiometric output proportional to 5 V excitation. The transducer uses advanced micromachining with thin-film metallization and bipolar processing to combine a high-sensitivity implanted strain gauge with low-drift signal-chain components. A pressure sensor (also called a pressure transducer) is a device that converts an applied pressure into an analog electrical signal, typically voltage. Piezoresistive sensors rely on strain gauges whose resistance changes with mechanical deformation of a silicon diaphragm. Within the sensor hierarchy, MPVZ5004GW7U sits inside the MEMS (micro-electromechanical systems) family, which itself is a subset of sensors and transducers. These conditioned parts include amplifier, temperature-compensation, and calibration stages on-die, so they connect directly to a microcontroller ADC without external analog front-end components. Key features include a full-scale span of 3.92 kPa, an output span of approximately 4.0 V (from 1 V at 0 kPa to 4.9 V at 3.92 kPa, assuming 5 V excitation), ratiometric output that tracks supply voltage, and an operating temperature range of 0 °C to 85 °C (per the device family datasheet). The 5.59 mm male tube port accepts a flexible hose and gives the part its "GW" (gauge, with port) package designation, distinguishing it from surface-mount leadless siblings. The transducer architecture uses a single-crystal silicon diaphragm with an implanted piezoresistive Wheatstone bridge. A first-stage differential amplifier and temperature-correction network run on the same die, producing a calibrated transfer function near VOUT = 5 V × (0.2 + P / 4.0 kPa) over the compensated band. Compared with ceramic-capacitive or discrete strain-gauge designs, this integration reduces calibration effort at end-of-line and improves long-term drift. Typical applications include medical respiratory airflow measurement (CPAP flow sensing), HVAC variable-air-volume (VAV) boxes, weather stations, altimeters, and process-control manifolds. The vented gauge reference simplifies absolute-pressure correction in patient monitoring. Designers should account for the gauge-port orientation and ensure the hose connection is leak-tight; see the manufacturer datasheet for derating curves above 85 °C and recommended PCB footprint when hand-soldering.
MPVZ5010G6U - 10kPa Vented Gauge Pressure Sensor | NXP
The NXP MPVZ5010G6U is a piezoresistive, on-chip signal-conditioned, temperature-compensated and calibrated monolithic silicon pressure sensor delivering an analog output of 0.2 V to 4.7 V proportional to applied pressure from 0 kPa to 10 kPa (1.45 PSI). It operates from a single 4.75 V to 5.25 V supply, drawing approximately 5 mA, and is housed in a small 8-pin SOP (8-SMD Module) surface-mount package. According to the manufacturer datasheet, the integrated ASIC performs offset, span and temperature calibration, removing the need for external compensation components in most applications. A piezoresistive pressure sensor is a transducer that uses strain-sensitive silicon resistors arranged in a Wheatstone bridge on a micromachined diaphragm. When differential pressure bends the diaphragm, the resistor values change, unbalancing the bridge and producing a voltage proportional to the applied pressure. The MPVZ5010G6U is part of the broader sensor category that sits below analog signal chain components (amplifiers, ADCs) in modern embedded systems, occupying the data-acquisition interface layer between physical phenomena and the digital processor. Key features include a typical full-scale span of 4.5 V (0.2 V to 4.7 V at 10 kPa), ratiometric analog output, accuracy of ±5% over 0 C to 85 C, ±2.5% maximum linearity, and a -40 C to +125 C operating temperature range. The vented gauge reference uses the rear side of the die exposed through a port on the package, providing absolute-altitude compensation relative to atmospheric pressure. An internal clock and decimation filter stabilise the output, and the on-chip ASIC eliminates the need for external active components. Typical applications include HVAC blower and filter pressure monitoring, air-handling control, respirator and CPAP airflow feedback, barometric altitude correction for GPS, appliance pressure sensing, weather stations, and small medical instrumentation where low noise ratiometric output and small form factor are required. The 8-SMD module is drop-in compatible with the larger MPXV5010G family, allowing PCB reuse where a no-port variant is acceptable. When designing with this part, observe the recommended decoupling network: a 0.1 uF ceramic capacitor close to VCC and a 47 nF capacitor on the output, with a 220 uF bulk capacitor near the supply to minimise ripple noise that couples directly into the analog output. The vented port must remain open to atmosphere - do not occlude it with potting compound or conformal coating.
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.

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.

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.

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. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
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. This page synthesizes drop-in alternative listings, distributor pricing tiers, and practical signal-conditioning design notes that go beyond the manufacturer datasheet summary.
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.
