MPXHZ6250AC6T1 - 20-250kPa Absolute Pressure Sensor | STMicroelectronics
The STMicroelectronics MPXHZ6250AC6T1 is a high-temperature-accuracy, integrated silicon pressure sensor that measures absolute pressure from 20 kPa to 250 kPa (2.9 to 36.26 PSI), housed in an 8-pin SOIC package with a top axial pressure port. It provides an analog output of 0.3 V to 4.9 V that is linearly proportional to applied pressure, with a sensitivity of approximately 20.4 mV/kPa and on-chip temperature compensation from -40 °C to +125 °C. According to the STMicroelectronics product page, the device integrates bipolar op-amp circuitry and thin-film resistor networks to deliver a high-level, calibrated analog output signal conditioned for direct microcontroller ADC input. What is an absolute pressure sensor? An absolute pressure sensor is a transducer that measures pressure relative to a perfect vacuum (zero reference), as opposed to gauge or differential sensors that measure relative to ambient or another port. Absolute pressure sensors are widely used in applications where a fixed vacuum reference is required - including barometric measurement, altimetry, weather stations, engine manifold absolute pressure (MAP) sensing, and sealed-system monitoring. Absolute pressure sensors sit within the broader hierarchy of pressure transducers -> MEMS sensors -> sensors -> electronic components. Key features include ±1.5 %FS accuracy, on-chip signal conditioning, calibrated and temperature-compensated output over the full -40 °C to +125 °C automotive range, and a media-resistant top-side port that accepts a 3.3 mm tube for pneumatic connection. The piezoresistive transducer element uses advanced micromachining and bipolar semiconductor processing for high reliability and stable long-term output. Supply voltage is nominally 5 V, and the ratiometric analog output simplifies ADC interfacing without precision voltage references. The architecture combines a monolithic silicon strain-gauge bridge with on-chip signal conditioning - including a precision bandgap reference, temperature compensation network, and output amplifier - so no external compensation components are required. This integrated approach achieves a calibrated, ratiometric output within ±1.5 %FS across the full pressure and temperature range, eliminating the need for end-of-line calibration in many applications. The exposed top-side port accepts standard 3.3 mm pneumatic tubing for direct media connection. Typical applications include manifold absolute pressure (MAP) sensing in automotive engine control units, barometric pressure measurement for weather stations and altimeters, industrial process control, HVAC pressure monitoring, and consumer appliance pressure sensing. The wide operating temperature range and high accuracy make the MPXHZ6250AC6T1 particularly suited for under-hood automotive and industrial environments. The top-port package simplifies manifold mounting compared to side-port alternatives. When designing with this device, ensure a stable 5 V supply and add a small RC filter on the output to suppress high-frequency noise from switching regulators and EMI sources in electrically noisy environments such as automotive engine bays. The ratiometric output means the supply voltage must be accurate or the output reading will scale proportionally with VCC.
MPXHZ6400A6T1 - 20-400kPa Absolute Pressure Sensor | NXP
The NXP MPXHZ6400A6T1 is an integrated silicon piezoresistive absolute pressure sensor with on-chip bipolar op-amp signal conditioning, temperature compensation, and factory calibration, housed in an 8-pin SSOP (Super Small Outline Package) with an axial port. It measures absolute pressure from 20 kPa to 400 kPa (2.9 PSI to 58.02 PSI) and provides a ratiometric analog output from 0.2 V to 4.8 V over a 4.64 V to 5.36 V supply range. An absolute pressure sensor is a transducer that measures pressure relative to a perfect vacuum rather than to ambient atmospheric pressure, making it ideal for sealed-system applications where the absolute reference must remain stable regardless of weather or altitude changes. Absolute pressure sensors belong to the broader family of MEMS (Micro-Electro-Mechanical Systems) pressure transducers, which sit within the sensor hierarchy of measurement semiconductors, and they are widely used where altitude, barometric, or sealed-cavity pressure must be quantified. Key features include ±1.5% accuracy over 0 °C to 85 °C, a temperature-compensated output spanning the full 20 kPa to 400 kPa range, media-resistant packaging tolerant of humid air and non-corrosive gases, and high electromagnetic immunity thanks to on-chip bipolar op-amp buffering. The integrated thin-film resistor network performs offset, span, and temperature calibration at the factory, eliminating the need for external compensation components. The sensor integrates a MEMS silicon diaphragm with a Wheatstone-bridge piezoresistor network. Differential strain on the diaphragm produces a differential bridge output that is amplified by the on-chip op-amp stage to the standard 0.2 V to 4.8 V full-scale ratiometric swing. Because the output is ratiometric to VCC, supply noise is rejected naturally and no precision voltage reference is required downstream. Typical applications include engine control manifold absolute pressure (MAP) sensing, barometric pressure measurement for weather stations and altimeters, HVAC system pressure monitoring, medical respiratory equipment, and industrial process control. Designers value the integrated calibration because it removes per-unit trimming during production and shortens time-to-market. When designing with this device, route the analog output through an RC low-pass filter (typically 1 kΩ and 100 nF) to attenuate high-frequency noise before the ADC input. The exposed axial port should be sealed with an O-ring and protected from liquid ingress, which can damage the MEMS element.

MPXHZ6400AC6T1 - 20-400kPa Absolute Pressure Sensor | NXP
The NXP MPXHZ6400AC6T1 is a media-resistant, high-temperature-accuracy integrated silicon absolute pressure sensor with on-chip bipolar op-amp signal conditioning, temperature compensation, and calibration. It measures absolute pressure from 20 kPa to 400 kPa (2.9 PSI to 58.02 PSI) and produces an analog output spanning 0.2 V to 4.8 V from a 5 V supply. It is housed in an 8-SSOP package with a top-facing pressure port and is shipped on tape-and-reel in 1,000-piece quantities. An absolute pressure sensor is a transducer that measures pressure referenced to a perfect vacuum rather than ambient atmosphere, making it ideal for sealed-system applications where the back side of the sensing element is evacuated and sealed. Within the sensor taxonomy, the MPXHZ6400AC6T1 sits in the integrated (signal-conditioned) absolute pressure sensor family, between raw piezoresistive MEMS cells (which require external amplification) and full digital I2C/SPI pressure modules (which integrate ADC and MCU on chip). It occupies the middle tier where the chip outputs a calibrated analog voltage but the application MCU still handles interpretation. Key features include a sensitivity of 12.1 mV/kPa, accuracy of plus/minus 1.5 percent full-scale span, and an operating temperature range of -40 C to +125 C. The integrated bipolar op-amp front end with thin-film resistor networks delivers a ratiometric output proportional to supply voltage, simplifying ADC interfacing. The top-port tubing interface accepts a 3.3 mm (0.13 inch) tube; the suffix C6 indicates the tube orientation. Technically, the device uses a single-port MEMS strain-gauge bridge that is laser-trimmed during manufacture. The on-chip conditioning corrects second-order temperature errors across the automotive-grade -40 C to +125 C range. Compared to the non-Z MPXH6400AC6T1, the Z suffix denotes media-resistant gel protection over the die for harsh media exposure. Typical applications include manifold absolute pressure (MAP) sensing in engine control units, industrial pneumatic monitoring, altimeter/barometric pressure modules, HVAC differential measurement, and motorcycle/small-engine fuel-pressure monitoring. The integrated calibration eliminates per-board trimming in production. Designers should treat the output as ratiometric with Vcc; if the ADC reference tracks Vcc, no extra calibration is required. Decouple Vcc with a 100 nF ceramic plus a 1 uF bulk capacitor placed within 5 mm of the supply pin to keep noise off the analog output stage.
MPXM2010D - 10kPa Differential Pressure Sensor | NXP
The NXP MPXM2010D is a 10 kPa differential piezoresistive silicon pressure sensor in a 5-SMD module package with on-chip temperature compensation and laser-trimmed calibration. According to the manufacturer datasheet, the device delivers a highly linear differential voltage output of 0 mV to 25 mV at 10 V excitation for a full-scale pressure of 1.45 PSI (10 kPa), with ±1% accuracy. The sensor operates from a single 10 V to 16 V supply and shares its monolithic silicon die with the MPX2010 and MPXV2010G family members. A piezoresistive pressure sensor is a transducer that converts an applied differential pressure into a proportional electrical output by exploiting the piezoresistive effect in doped silicon — when mechanical strain is applied to a diaphragm embedded with Wheatstone-bridge resistors, the resistance values shift predictably and unbalance the bridge. The monolithic silicon die integrates both the strain gauge and the thin-film resistor network, making the device a member of the transducer family within sensor signal-conditioning components used in industrial, medical, and HVAC systems. Key features of the MPXM2010D include on-chip temperature compensation from 0 °C to +85 °C, ratiometric output scaled to supply voltage for improved ADC accuracy, and ±1.5 % linearity over the pressure range. The 5-SMD module package includes the dual vertical-port tubing geometry that defines the 'M' (modular) variant of the MPX2010 family. The single-supply 10 V to 16 V operating range simplifies analog front-end design in 4 mA-to-20 mA loop-powered systems. Typical applications include medical inhalation therapy devices, HVAC variable-air-volume (VAV) controllers, industrial process control loops, level sensing in non-corrosive fluid reservoirs, and barometric calibration of digital altimeters. The differential port configuration enables bidirectional pressure measurement — a critical requirement in flow metering for medical ventilators where the drop across a flow element must be sensed. When designing with the device, place the part after a low-noise instrumentation amplifier and use a 16-bit ADC for full-scale resolution. The output is ratiometric to the supply — variations in excitation voltage will scale the output proportionally, so use a precision reference or well-regulated supply to maintain accuracy.

MPXM2010GS - 10kPa Vented Gauge Pressure Sensor | NXP/STMicro
The NXP MPXM2010GS is a 10 kPa (1.45 PSI) on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor packaged in a 5-SMD module with a top-port, male 0.12" (2.97 mm) tube inlet. The monolithic silicon diaphragm integrates a strain-gauge Wheatstone bridge plus a thin-film resistor network, laser-trimmed for precise span, offset, and temperature compensation. With a 10 V excitation the device delivers a linear differential output of 0 mV to 25 mV across the 0 to 10 kPa pressure range. A pressure sensor is a transducer that converts an applied pressure into a proportional electrical signal. Piezoresistive sensors, the family to which the MPXM2010GS belongs, exploit the change of silicon resistivity under mechanical strain. This class of sensor sits hierarchically below MEMS sensors and above general-purpose transducers in the sensor taxonomy, offering higher accuracy than ceramic capacitive cells but lower bandwidth than resonant or optical alternatives. Within pressure-sensor terminology, "vented gauge" means the back side of the diaphragm is open to ambient atmosphere through a vent port, so the output reflects differential pressure relative to local barometric conditions. The MPXM2010GS series provides nominal 2.5 mV/kPa sensitivity, very low pressure hysteresis, and excellent long-term stability over its -40 °C to +125 °C operating range. Its vented-gauge topology makes it especially attractive for applications that must reject package-stress and reference local atmospheric pressure. The uncompensated output voltage span remains consistent across temperature thanks to the on-chip thin-film compensation network, simplifying downstream signal conditioning. Typical applications include medical respiration monitors, HVAC air-flow measurement, weather-station barometric sensing, appliance pressure feedback, and industrial process control loops. The vented-gauge configuration with tube-port inlet suits enclosed module designs where reference-to-ambient accuracy matters more than fully-sealed absolute measurement. Designers should excite the bridge from a low-noise, low-drift 10 V reference and amplify the millivolt-level output with an instrumentation amplifier such as the INA128 or AD620. PCB layout should keep ground loops away from the sensor body, and the vent tube must remain unobstructed to preserve gauge accuracy. This page consolidates distributor pricing, drop-in alternatives, and application guidance that the manufacturer datasheet alone does not surface.
MPXM2051GST1 - 50kPa Gauge Pressure Sensor, 5-SMD | NXP
The NXP MPXM2051GST1 is a silicon piezoresistive pressure sensor providing a linear voltage output directly proportional to the applied pressure, rated for 0 to 50 kPa (0 to 7.25 PSI) gauge measurement in a 5-SMD top-port module with a male 0.12" (2.97 mm) tube inlet. It delivers 0 mV to 40 mV output at a 10 V supply, with on-chip temperature compensation and calibration over 0 C to 85 C. A piezoresistive pressure sensor is a MEMS device in which a micromachined silicon diaphragm with embedded piezoresistive strain gauges converts mechanical pressure into a small differential voltage via the Wheatstone-bridge principle; within the sensor taxonomy it sits under MEMS pressure sensors -> pressure sensors -> sensors -> signal conditioning. This category of device is widely used where a precise, ratiometric analog pressure reading is needed without requiring an external front-end IC or ADC. Key differentiating features of the MPXM2051GST1 include on-chip temperature compensation and factory calibration, eliminating external compensation networks; a typical full-scale span of 40 mV at 10 V excitation (sensitivity ~0.8 mV/V); a maximum combined nonlinearity and pressure hysteresis of approximately ±0.4 %FSS (per the MPXM2051G datasheet); and a top-side tube port that simplifies pneumatic interface in manifold-style assemblies. The 5-SMD MPAK-4 (with tab) form factor suits surface-mount PCB assembly while preserving the through-port geometry. Technically, the device uses a monolithic silicon diaphragm with an integrated piezoresistive bridge. The differential output is a ratiometric analog voltage whose percentage deviation from nominal span closely tracks the percentage deviation of the input pressure from full scale. The vented-gauge reference allows barometric-pressure-compensated measurements in vented applications, which is critical for medical and HVAC equipment. Typical applications include medical respiratory instrumentation, HVAC air-flow monitoring, barometric correction for altitude-compensated devices, pneumatic control, and industrial process monitoring. The 50 kPa range suits low-pressure gas and air measurements in portable medical and HVAC equipment. When designing with this part, prefer a low-noise, regulated excitation source for the 10 V supply to maintain ratiometric accuracy; the bridge output is millivolt-level and requires a low-offset, low-noise instrumentation amplifier with adequate gain to feed an ADC. This page synthesizes drop-in alternatives, design notes, and FAQ content beyond the manufacturer datasheet to help engineers confidently select and integrate the MPXM2051GST1.
MPXM2053D - 50kPa Differential Pressure Sensor, 10V | NXP
The NXP MPXM2053D is a 50 kPa on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor in a 5-SMD module (MPAK-style). It provides a highly accurate and linear differential voltage output directly proportional to applied pressure over a 0-50 kPa (0-7.25 PSI) range. The sensor is specified for 10 V typical excitation and delivers a nominal 0 mV to 40 mV full-scale span across the rated pressure. A piezoresistive pressure sensor is a MEMS device in which strain gauges diffused into a silicon diaphragm change resistance when the diaphragm flexes under differential pressure. The MPXM2053D integrates the strain-gauge bridge, a thin-film resistor network, and laser-trimmed calibration on a single monolithic die, yielding an analog millivolt output proportional to pressure without requiring external signal conditioning. Within the broader taxonomy, it sits as: pressure sensor -> MEMS sensor -> sensor -> electronic component. Related synonyms include piezoresistive transducer, strain-gauge pressure transducer, and Wheatstone-bridge pressure sensor. Key specifications include 0-50 kPa differential pressure range, 0-40 mV full-scale output at 10 V supply, 1.0 kohm typical bridge impedance, 0.25% linearity (typical for the MPX2053 family), and an operating temperature range of -40C to +125C. The on-chip temperature compensation and laser-trimmed offset/span calibration remove the need for external trimming in most applications. The 5-SMD module package supports through-hole-style port mounting with surface-mount lead forming. The MPXM2053D uses a single monolithic silicon diaphragm and integrated thin-film network that together produce a Wheatstone-bridge output. The bridge is laser-trimmed for span, offset, and temperature compensation, achieving stable millivolt-mV-per-kPa sensitivity over industrial temperature ranges. The chip-level calibration enables system designers to bypass per-board trimming while still meeting typical medical, industrial, and consumer accuracy targets. Typical applications include pump and motor control, robotics and end-effector force feedback, level detection in tanks, medical diagnostics (such as non-invasive blood pressure monitors and ventilators), HVAC pressure switching, and appliance water-level sensing. The differential topology makes it well suited to measuring gauge pressure relative to a reference port or to other chambers. Designers should evaluate the small mV-level output and add a low-offset, low-noise instrumentation amplifier (e.g. INA333 or equivalent) to drive an ADC. Proper PCB layout, port sealing, and isolation from package stress are critical because the SMD lead frame can transmit mechanical strain to the die. This page consolidates distributor pricing, drop-in alternatives within the same MPX2053 family, and design guidance that goes beyond the manufacturer datasheet's parameter table.
MPXM2102A - 100kPa Absolute Pressure Sensor, 10V | NXP
The NXP MPXM2102A is a 100 kPa on-chip temperature-compensated silicon piezoresistive absolute pressure sensor in a 5-MPAK surface-mount module, delivering a linear Wheatstone-bridge output of 0 mV to 40 mV at a 10 V excitation. Operating range spans 0 kPa to 100 kPa (14.5 PSI absolute), with a maximum overpressure capability of 400 kPa (58.02 PSI). The transducer is housed in a 5-SMD (gull-wing) module with no port, suitable for board-mount pressure acquisition. An absolute pressure sensor is a transducer that generates an electronic signal as a direct function of the pressure imposed on its sensing diaphragm, referenced to a sealed internal vacuum cavity rather than ambient air. Piezoresistive sensors belong to the broader sensor hierarchy of MEMS devices -> semiconductor transducers -> signal-conditioning front-ends, and they are commonly paired with instrumentation amplifiers in the system signal chain. The MPXM2102A integrates on-chip temperature compensation, eliminating the need for external thermistor linearization in many embedded designs. Key features include a typical full-scale span of 40 mV at 10 V excitation, a 1.0 kOhm bridge impedance, ±0.1% linearity across the 0-100 kPa range, and a -40C to +125C operating temperature window with calibrated thermal behavior. The device operates from a 10 V DC nominal supply with low current draw, and its 5-MPAK module package provides easy PCB mounting alongside standard SMD components. The Wheatstone-bridge output enables direct interface to a differential ADC or op-amp front end. The MPXM2102A uses a monolithic silicon strain-gauge diaphragm die bonded inside the plastic 5-MPAK housing, with laser-trimmed resistors providing temperature compensation across the qualified range. Pressure applied to the front face deflects the diaphragm, changing the piezoresistor bridge balance and producing a differential millivolt signal proportional to absolute pressure. This analog output preserves native fidelity and lets designers choose their own amplification and filtering topology. Typical applications include medical spirometers and patient monitors, industrial process-control pressure transmitters, barometric altimeter reference designs, HVAC duct pressure sensing, and portable gas flow instrumentation. The 14.5 PSI absolute range suits body-pressure, weather-station, and low-pressure industrial use cases. When designing with the MPXM2102A, route the bridge excitation through a quiet, low-noise supply and place an instrumentation amplifier (such as an INA126 or AD620) within 20 mm of the output pins to minimize common-mode pickup. Use separate analog and digital grounds tied at a single star point near the ADC. This page synthesizes distributor pricing, pin-compatible drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
MPXM2102AS - 100kPa Absolute Pressure Sensor | NXP | Industrial
The NXP MPXM2102AS is a 100 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor that delivers a linear analog voltage output directly proportional to applied absolute pressure, housed in a 5-SMD module (top port) with a 0.12" (2.97 mm) tube inlet. A piezoresistive pressure sensor is a transducer that converts applied pressure into a proportional electrical signal by exploiting the piezoresistive effect of silicon — when mechanical strain is applied to a doped silicon resistor, its resistance changes predictably. In the bridge topology used here, four strain gauges form a Wheatstone bridge on a monolithic silicon diaphragm; an applied pressure deflects the diaphragm and unbalances the bridge, producing a differential output voltage that scales linearly with pressure. The on-chip thin-film resistor network calibrates and temperature-compensates this output, placing absolute-pressure sensing in the broader transducer hierarchy alongside gauge (relative) and differential pressure sensors. These sensors sit within the broader MEMS and sensor category used in industrial, medical, and HVAC equipment. Key features of the MPXM2102AS include an operating pressure range of 0 to 100 kPa (0 to 14.5 PSI absolute), a typical full-scale output of 40 mV at 10 V excitation, an offset of 0 mV, and a supply voltage of up to 10 V DC. The integrated calibration network provides temperature compensation across 0C to 85C, simplifying the analog front-end design by removing the need for external compensation circuitry. The 5-SMD top-port package accepts a 2.97 mm tube, allowing in-line pneumatic connection in sealed systems. Architecturally, the device uses a single monolithic silicon die with an integrated vacuum reference for absolute measurement. The piezoresistive bridge delivers a ratiometric output proportional to supply voltage, which simplifies ADC interfacing across varying supply rails. Typical non-linearity is in the low-percent range, and the calibration laser-trimmed resistor network standardizes part-to-part output across production lots, supporting system-level accuracy without per-unit trimming. Typical applications include barometric and weather-station instrumentation, medical respiratory equipment, altimeters and variometers, industrial process control, and HVAC duct pressure monitoring where 0-100 kPa absolute pressure conversion into a clean analog signal is required. When designing with this device, drive the input from a low-noise regulated supply to minimize excitation drift and add an instrumentation amplifier at the differential outputs for single-ended ADC conversion.
MPXM2102AST1 - 100kPa Absolute Pressure Sensor | STMicroelectronics
The STMicroelectronics MPXM2102AST1 is a 100 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor in a 5-pin M-PAK (MPAK) surface-mount module with a top axial port. It delivers a linear differential analog output of 0 mV to 40 mV at 10V excitation, with an absolute operating pressure range of 20 kPa to 100 kPa (14.5 PSI max) over the compensated 0 °C to +85 °C range. The sensor uses a single monolithic silicon diaphragm with on-chip strain gauge and thin-film resistor network, laser-trimmed for span, offset calibration, and temperature compensation. A piezoresistive pressure sensor converts applied force on a silicon diaphragm into a small resistance change in an embedded Wheatstone bridge; the resulting millivolt-level differential output is directly proportional to pressure. The MPX2102 series sits in the pressure sensor -> sensor -> transducer hierarchy used in industrial, medical, and consumer systems where a clean, temperature-stable analog pressure signal is required. Key features include 0 mV to 40 mV full-scale span (10V supply), 5.0 µV/V/kPa typical sensitivity offset, 1.0% max linearity error, and on-chip temperature compensation from 0 °C to +85 °C. The M-PAK 5-SMD module provides a single axial 0.12" (2.97 mm) tube port for vertical mounting, plus surface-mount gull-wing leads for PCB attachment and a tab for mechanical stability. The series draws ~6 mA from a 10V typical supply (16V max). The device is a silicon piezoresistive transducer in which the diaphragm strain gauge forms one leg of a Wheatstone bridge; laser-trimmed thin-film resistors null the bridge and calibrate the temperature coefficient, removing the need for external compensation networks. The four-active-lead M-PAK pinout plus grounded tab provides clean EMI behavior when the tab is soldered to a grounded copper pour. Typical applications include medical respiratory and patient monitoring, industrial process pressure measurement, HVAC transducers, altimeters/barometers, and portable barometric instruments. The absolute-pressure reference (vacuum sealed on the back side of the die) makes the device particularly suitable for barometric / weather-station use. The differential 0-40 mV output requires an external low-offset amplifier (e.g., instrumentation amp) for high-resolution ADC interfaces. Design tip: use a low-noise, low-offset instrumentation amplifier (such as TI INA122 or similar) to condition the 0-40 mV bridge output, route the analog traces over a continuous ground pour, and add 0.1 µF decoupling close to the supply pin to keep switching noise out of the bridge measurement.

It operates from a 10 V dc excitation supply and produces a linear, ratiometric analog voltage output directly proportional to applied pressure over a 0 to 100 kPa range. On-chip temperature compensation and calibration provide a span of approximately 40 mV at 10 V excitation, simplifying signal conditioning by allowing direct connection to an external ADC front-end. A piezoresistive pressure sensor is a MEMS device in which diffused strain gauges on a silicon diaphragm change resistance under applied pressure, generating a small differential voltage that is proportional to pressure. The MPXM2102A family belongs to the broader category of board-mount pressure sensors (sensor -> transducer -> MEMS -> semiconductor) used wherever a clean, linear, calibrated pressure signal is required without a discrete amplifier circuit. Key features include a 0 to 100 kPa operating pressure range (approximately 0 to 14.5 psi or 0 to 1 bar), ratiometric output for accuracy over supply variation, internal temperature compensation across 0 to 85 °C, and a robust single-element port (Sensor-5 case style) suitable for manifold mounting. The integrated signal-conditioning circuitry delivers a typical full-scale span of 40 mV at 10 V excitation, useful for low-noise instrumentation readouts. The MPXM2102A architecture uses an X-ducer strain gauge on a chemically-etched silicon diaphragm; the on-chip thin-film network performs offset, span and temperature calibration, eliminating external compensation resistors. The 10 V unipolar excitation is intentionally high to maximize output span and PSRR-style supply-noise rejection in industrial cabling environments. Typical applications include medical spirometers and patient monitors, HVAC air-flow monitoring, altimeters and barometric instruments, industrial pneumatic controls, and process-control analog front-ends. The Sensor-5 package provides a barbed pressure port for tube attachment in low-pressure gas-flow designs. When designing with this part, add a ratiometric ADC reference tied to the 5 V (or 10 V) excitation rail to preserve accuracy when supply tolerance drifts. Choose MPXM2102AST1 without the tape-and-reel trailer if your line is hand-loaded or you are prototyping with through-hole Sensor-5 sockets.
MPXM2102D - 100kPa Differential Pressure Sensor, M-PAK | NXP
The NXP MPXM2102D is a silicon piezoresistive differential pressure sensor offering a 0 to 100 kPa (0 to 14.5 psi) measurement range with a linear analog voltage output of 0 mV to 40 mV at a 10 V supply. Housed in a 5-SMD M-PAK module, the device integrates on-chip temperature compensation and calibration, providing a stable, ratiometric output directly proportional to applied differential pressure. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a solid-state transducer that uses strain-induced resistance changes in a silicon diaphragm to convert applied pressure into a voltage. The sensor element itself is one tier in a broader transducer hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor IC. Piezoresistive sensors occupy the high-accuracy, low-pressure niche of this family, contrasted against capacitive (high sensitivity) and resonant (high stability) alternatives. They are widely used in medical and industrial applications where linearity, small size, and analog output simplicity outweigh the need for a digital interface. Key features include a full-scale output of 40 mV at 10 V excitation, a sensitivity of 0.4 mV/kPa, an operating temperature range of -40C to +125C, and a differential/gauge measurement topology with dual horizontal ports. The integrated temperature compensation covers 0 to 85C with a typical temperature coefficient of 0.5% FS, and the monolithic silicon diaphragm is laser-trimmed during calibration to minimize offset and span errors across the operating range. The MPXM2102D is built on NXP's mature MEMS process and a Wheatstone-bridge piezoresistive network diffused into the silicon diaphragm. The bridge excitation is ratiometric with the supply voltage, so the output scales linearly with Vex, enabling simple ADC conversion without a precision reference. The M-PAK 5-SMD module ports pressure horizontally through two opposed inlets, simplifying plumbing on both sides of a manifold or flow channel. Typical applications include medical respiratory monitoring (spirometers, ventilators), HVAC differential pressure sensing, industrial process control, gas flow measurement, and altimeter/barometer modules. The differential topology is well suited to measuring pressure drop across a flow element or the positive/negative pressure swing in a pneumatic actuator. When designing with this device, decouple the Vex supply with a 0.1 uF ceramic capacitor placed as close as possible to pins 2 and 4, and ensure the bridge output is conditioned by a low-offset, low-noise instrumentation amplifier such as the INA128 or MPX2010 to drive an ADC. Avoid mechanically stressing the M-PAK housing or the ports, as package strain couples directly into the diaphragm and degrades accuracy.

MPXM2102GS - 100kPa Vented Gauge Pressure Sensor | NXP
The NXP MPXM2102GS is a 100 kPa piezoresistive silicon pressure sensor with a vented-gauge (Gage) topology, providing an analog output voltage proportional to applied pressure in a 5-pin M-PAC (MPAK-4) surface-mount module with a top-mounted tube port. According to NXP product information, the device outputs 0 mV to 40 mV at 10 V excitation over a 0 to 100 kPa pressure range, delivering a linear response suitable for direct ADC conversion after instrumentation amplification. A piezoresistive pressure sensor is a solid-state transducer in which strain gauges diffused into a silicon diaphragm change resistance when the diaphragm flexes under pressure; the resulting Wheatstone bridge produces a differential voltage proportional to pressure. Piezoresistive pressure sensors sit in the transducer hierarchy: pressure sensor -> MEMS sensor -> sensor -> discrete semiconductor, and serve as the front-end element in medical, HVAC, and industrial instrumentation. Key features of the MPXM2102GS include on-chip temperature compensation and calibration via laser-trimmed thin-film resistors, providing span and offset accuracy that minimizes external calibration circuitry. The single monolithic diaphragm with integrated strain gauge network ensures long-term stability and mechanical robustness. Operating pressure range is 0 to 100 kPa (approximately 0 to 14.5 PSI), with sensitivity near 0.4 mV/kPa at 10 V supply. The 5-pin M-PAC (MPAK-4) package with top port simplifies tubing connections in pressure test setups. Typical applications include barometric and altitude measurement for weather monitoring stations, medical spirometers and non-invasive blood pressure monitors, HVAC differential pressure sensing, and industrial process control loops requiring accurate low-pressure measurement. The vented-gauge reference (port exposed to atmosphere through the package vent) makes the device ideal for applications where the measurement differential versus ambient pressure is the quantity of interest. When designing with the MPXM2102GS, use an instrumentation amplifier such as INA333 or AD620 to amplify the millivolt-level output to a 0-5 V or 4-20 mA range; provide a stable low-noise 10 V excitation; and add adequate filtering on the supply to reject EMI. Do not apply pressure exceeding the rated 100 kPa range to avoid permanent diaphragm damage.

MPXM2202A - 200kPa Absolute Pressure Sensor 5-SMD | NXP/ST
The NXP MPXM2202A is a 200 kPa (29.01 PSI) absolute pressure sensor in a 5-SMD module package with on-chip temperature compensation and calibration, providing a linear analog voltage output proportional to applied pressure. The device integrates a monolithic silicon diaphragm with strain-gauge piezoresistors and a thin-film resistor network, laser-trimmed for span, offset, and temperature compensation between 0°C and +85°C. The output spans 0 mV to 40 mV at 10V excitation over the 0 kPa to 200 kPa range. A piezoresistive pressure sensor converts mechanical pressure into an electrical signal by exploiting the piezoresistive effect in silicon: when strain gauges on a flexing diaphragm change resistance, a Wheatstone bridge produces a differential voltage proportional to applied pressure. Absolute-pressure variants like the MPXM2202A reference a sealed vacuum cavity on-chip, so output is referenced to absolute zero pressure rather than ambient. This category sits within the broader sensor hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor IC -> semiconductor. Key features include 0°C to +85°C calibrated temperature range, 0 mV to 40 mV full-scale span at 10V supply, 0 to 200 kPa operating range, on-chip temperature compensation, and a small surface-mount 5-SMD module. The integrated compensation removes the need for external calibration circuitry, simplifying analog front-end design. The MPXM2202A uses a single monolithic silicon die containing the sensing diaphragm and the signal-conditioning thin-film network. Laser trimming during manufacture corrects both span and offset errors, while the on-chip temperature-compensation network minimizes thermal drift across the calibrated band. This architecture yields a robust analog output suitable for direct connection to instrumentation amplifiers or microcontroller ADCs. Typical applications include medical instrumentation (respiratory monitors, infusion pumps), industrial pressure monitoring, HVAC transducers, altimeters and barometric systems, and process-control loops where a calibrated analog pressure signal is required. The 0-40 mV span suits low-noise instrumentation amplifier front-ends. When designing with this sensor, ensure a clean, low-noise 10V excitation supply because output span scales linearly with supply. Add a low-offset, low-noise instrumentation amplifier (e.g. INA128) to amplify the 0-40 mV signal to a useful ADC range, and apply proper bypass/decoupling at the supply pins.

MPXM2202AS - 200 kPa Absolute Pressure Sensor, M-PAC | NXP
The NXP MPXM2202AS is a 200 kPa on-chip temperature-compensated silicon piezoresistive pressure sensor supplied in a 5-pin M-PAC top-port SMD module. It provides a differential analog output of 0 mV to 40 mV at 10 V excitation, sampling absolute pressure from 0 kPa to 200 kPa (0-29.01 PSI) through a 0.12" (2.97 mm) tube port. According to the NXP product listing, the device is packed in TUBE-TUBE MULTIPLE NDP with a minimum package quantity of 60 and minimum order quantity of 1200, at a budgetary price of $5.86 USD per 1k units. A piezoresistive pressure sensor is a micro-electro-mechanical (MEMS) device in which a silicon diaphragm with diffused strain gauges converts applied pressure into a proportional change in resistance. The MPXM2202AS integrates the sensing die, on-chip temperature compensation network, and signal-conditioning resistors in a single surface-mount module, allowing direct interface to an external ADC or instrumentation amplifier. Within the broader sensor taxonomy, it sits as: pressure sensor -> MEMS sensor -> transducer -> sensor IC -> semiconductor. The MPX2202/MPXM2202 family is the legacy industrial/medical successor to the original Motorola MPX2000 series piezoresistive cells. Key features include 0 mV to 40 mV full-scale output (typ. 0.2 mV/kPa sensitivity), 10 V typical excitation, on-chip temperature compensation across 0C to 85C, and an absolute pressure reference sealed inside the package. The 5-pin M-PAC package simplifies PCB layout compared to the larger unibody MPX2202GP variant, while preserving the same Wheatstone-bridge pinout. The sensor is intended for clean, dry, non-corrosive gases. The MPXM2202AS relies on a single-axial piezoresistive bridge: four ion-implanted resistors on a silicon diaphragm form a Wheatstone configuration, balancing at 0 kPa and unbalancing linearly with applied pressure. The on-chip compensation network cancels the first-order temperature coefficient of the bridge, allowing raw mV output to be read directly with reasonable accuracy over the 0-85C range. Typical applications include medical inhalers and patient monitors, HVAC pressure transmitters, altimeters and barometric instruments, industrial process control, and pneumatic system monitoring. For battery-powered designs, consider newer I2C/SPI digital sensors such as the NXP MPL3115A2 or the Bosch BMP280; the MPXM2202AS is best suited to systems that already have a stable 10 V analog supply and an ADC front end. When designing with this part, route the high-impedance bridge outputs on a guard trace or shield and place the ADC sample-and-hold within 50 mm of the output pins. Apply the 10 V excitation through a low-noise LDO such as the TPS7A4701 to avoid bridge self-heating drift.

MPXM2202GST1 - 200kPa Vented Gauge Pressure Sensor | STMicroelectronics
The STMicroelectronics MPXM2202GST1 is a 200 kPa (29.01 psi) piezoresistive pressure sensor in a 5-SMD M-PAK module with a top-side male tube port. It provides a calibrated, temperature-compensated differential analog output of 0 mV to 40 mV at 10 V excitation, originally from the Freescale/NXP MPX2202 family and now manufactured and supported by STMicroelectronics. A piezoresistive pressure sensor is a MEMS device in which a thin silicon diaphragm with embedded strain gauges changes resistance when pressure is applied; an external circuit or ADC then converts the millivolt-level output into a pressure reading. Pressure sensors sit in the sensor hierarchy under transducers, and board-mount variants like the MPXM2202GST1 belong to the wired medical / industrial / HVAC equipment ecosystem where gas or fluid pressure must be measured directly on a printed circuit board. Key features include 0 mV to 40 mV full-scale span at 10 V supply, ±0.25% linearity over the 0–200 kPa range, on-chip temperature compensation from 0 °C to +85 °C, and a vented-gauge reference that compensates for ambient barometric pressure variation. The M-PAK package includes a barbed 0.12" (2.97 mm) tube port for pneumatic connection and five surface-mount leads for PCB reflow soldering. Internally, the device is a monolithic silicon die with a piezoresistive Wheatstone bridge, laser-trimmed span and offset for tight device-to-device matching. The vented-gauge construction means the back side of the diaphragm is exposed to atmosphere through the port, allowing absolute barometric correction in single-sided applications without a secondary reference sensor. Typical applications include medical ventilators and respiratory monitors, HVAC air-flow meters, industrial process controls, altimeters and barometers, and portable gas-flow instrumentation. Designers choose this part when they need a proven, board-mount pressure-sensing building block with analog output for easy interface to instrumentation-grade ADCs or MCU analog front ends. Design tip: drive the sensor from a low-noise, well-regulated 10 V excitation supply and use an instrumentation amplifier with sufficient gain (typically 100×–250×) to bring the 40 mV span to a 0–4 V or 0–5 V ADC input range. Decouple VCC close to the pins with a 0.1 µF ceramic capacitor to suppress switching-noise coupling.

MPXV10GC6U - 10 kPa Vented Gauge Pressure Sensor | NXP/STMicro
The NXP Semiconductors MPXV10GC6U is a 10 kPa (1.45 PSI) vented gauge uncompensated silicon piezoresistive pressure sensor housed in an 8-pin SO (Small Outline, gull-wing SMD) package with a top-side 3.18 mm tube port. The sensor delivers a linear differential analog output of 0 mV to 35 mV at a 3 V excitation, proportional to applied pressure, making it suitable for medical, industrial, and HVAC pressure measurement applications. A piezoresistive pressure sensor is a MEMS device in which a silicon diaphragm with embedded strain-resistive elements deflects under pressure, producing a differential voltage output via a Wheatstone bridge. Within the sensor hierarchy, the MPXV10GC6U belongs to the family of uncompensated raw-bridge pressure sensors, which sit below calibrated/temperature-compensated sensors but above simple mechanical pressure switches. Engineers select uncompensated parts when they want to apply custom linearization, temperature compensation, and amplification networks in firmware or with external op-amps. Key features include a 0 to 10 kPa operating range with vented gauge reference, 35 mV full-scale output at 3 V supply, low power consumption suitable for portable or battery-powered systems, and a top-side tube port (3.18 mm / 0.13") for hose-attach pneumatic interfacing. The uncompensated nature means the sensor ships without onboard calibration, giving designers full control over offset, span, and thermal compensation. The MPXV10GC6U uses a single-element piezoresistive bridge fabricated on a silicon die. Output is ratiometric to supply voltage, which simplifies system-level calibration when the excitation is also used as the ADC reference. Designers must add a low-noise instrumentation front-end (typically an op-amp with adjustable gain) and an external temperature compensation network because raw bridge output drifts with temperature. Typical applications include medical respiratory monitoring, HVAC airflow sensing, altimeters and barometric aids, industrial process control, and consumer health devices such as blood pressure monitors. The vented gauge reference simplifies absolute-pressure readouts when paired with a calibrated airflow inlet. When designing with this sensor, place a low-offset, low-noise instrumentation amplifier directly adjacent to the output pins to avoid PCB-level noise pickup on the millivolt-scale signal. Use ratiometric ADC sampling tied to the same 3 V excitation as the bridge to cancel supply-noise error. This page synthesizes distributor pricing, drop-in alternatives, application circuits, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single, decision-ready reference for the MPXV10GC6U.
MPXV10GC7U - 10 kPa Vented Gauge Pressure Sensor | NXP
The NXP MPXV10GC7U is a 10 kPa uncompensated silicon piezoresistive pressure sensor in an 8-DIP through-hole package (0.550" / 13.97 mm) with a top-port 0.13" (3.18 mm) tube inlet. It delivers an analog voltage output proportional to applied vented-gauge pressure over a 0 mV to 35 mV span when excited at 3 V supply, with a typical sensitivity of 3.5 mV/kPa. The device uses a monolithic silicon diaphragm with a diffused Wheatstone bridge, producing an accurate, linear mV output across the 0 to 10 kPa (1.45 PSI) range without onboard signal conditioning. A piezoresistive pressure sensor is a MEMS device that converts mechanical pressure applied to a silicon diaphragm into a small differential voltage using diffused strain-sensitive resistors arranged in a Wheatstone bridge. Within the broader taxonomy, MPXV10GC7U sits in: pressure sensor -> pressure transducer -> sensor -> MEMS -> semiconductor. It belongs to the family of uncompensated, low-pressure, gauge-type devices intended for medical, HVAC, and analytical instrumentation where downstream ADC and amplifier stages provide calibration, temperature compensation, and offset correction. Key features include a 0 to 10 kPa operating pressure span, 35 mV full-scale output at 3 V excitation, 3.5 mV/kPa nominal sensitivity, differential bridge topology, and a vented gauge reference port that automatically compensates for atmospheric pressure variations. The robust 8-DIP package with port tube simplifies tubing to the media and provides mechanical isolation for the silicon die. Operating supply range is 3 V to 6 V, allowing direct excitation from standard 3.3 V or 5 V rails. The sensing element is fabricated using NXP's bulk-micromachined silicon process, where the four bridge resistors are ion-implanted directly into the diaphragm. Because the output is uncompensated, designers must apply external offset trim and temperature compensation in firmware or analog circuitry to meet absolute accuracy targets; this is the trade-off for the device's low cost and small signal path. Typical applications include medical respiratory monitoring, digital blood pressure cuffs, HVAC flow and pressure instrumentation, barometric reference circuits, and analytical instrument front ends. The vented gauge topology makes it ideal when atmospheric reference compensation is desired without an additional reference port routing. When designing with this part, plan for an instrumentation front-end (INA with gain of ~100) and a 16-bit or higher ADC to recover useful pressure resolution; sensor self-heating should be minimized by limiting excitation current and using pulsed excitation where the system allows. PCB layout should keep the high-impedance bridge traces short and guarded. This page consolidates distributor pricing, drop-in MPX-series alternatives, and practical front-end design notes that are not duplicated in the manufacturer datasheet.
MPXV12GW6U - 10 kPa Uncompensated Pressure Sensor | NXP
The NXP MPXV12GW6U is a 10 kPa (1.45 PSI) uncompensated silicon piezoresistive pressure sensor in an 8-SMD gull-wing package with a top-side port (0.22" / 5.59 mm tube), delivering a 0 mV to 55 mV analog output at 3 V supply. A piezoresistive pressure sensor is a micro-electromechanical (MEMS) transducer that uses strain-sensitive diffused resistors on a silicon diaphragm to convert applied differential or gauge pressure into a small differential voltage. These devices sit in the sensor hierarchy as follows: pressure sensor -> MEMS sensor -> transducer -> sensor IC -> semiconductor. Uncompensated sensors require external calibration, amplification, and temperature compensation at the signal-conditioning stage, but offer the lowest cost and the highest raw sensitivity per dollar for OEM designs. Key features of the MPXV12GW6U include a 0 mV to 55 mV full-scale output, 10 kPa nominal pressure range (1.45 PSI), a vented gauge configuration for true reference against atmosphere, and a 3 V typical supply that allows low-voltage battery operation. The top-port tube geometry (5.59 mm) accepts standard pneumatic fittings and simplifies plumbing in medical and industrial equipment. Operating temperature spans -40 C to +125 C, enabling use in non-automotive harsh environments. Internally, the MPX12 series uses a single-piece silicon diaphragm with four piezoresistive strain gauges arranged in a Wheatstone bridge. Excitation across the bridge produces a millivolt-level differential output proportional to pressure. Because no on-chip compensation is provided, designers add a low-offset op-amp such as the NXP INA333 or Texas Instruments INA333 and a temperature-compensation network to achieve system-level accuracy. Typical applications include medical inhalation / respiration flow monitors, HVAC differential pressure transmitters, air-flow and level sensing in industrial equipment, and low-pressure process instrumentation. The vented gauge reference makes it ideal when barometric correction is required. When designing with this part, place a high-gain, low-noise instrumentation amplifier directly at the sensor output to avoid injecting PCB-level noise into the millivolt signal. Add a temperature compensation network to flatten the millivolt span across the full -40 C to +125 C range, since piezoresistive sensitivity drifts roughly -1.9 %/C at constant excitation. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single reference for part selection.
MPXV2010DP - 10kPa Differential Pressure Sensor, 8-BSOP | STMicroelectronics
The STMicroelectronics MPXV2010DP is a 10 kPa differential silicon piezoresistive pressure sensor in an 8-BSOP (12.06 mm width) surface-mount package with dual ports on the same side. It delivers a linear differential analog output of 0 mV to 25 mV at 10 V supply, calibrated and temperature-compensated on-chip, with operating pressure from 0 kPa to 10 kPa (0 PSI to 1.45 PSI). A piezoresistive pressure sensor is a MEMS device whose Wheatstone-bridge strain gauges are diffused into a monolithic silicon diaphragm; flexure of the diaphragm under pressure unbalances the bridge and produces an output voltage directly proportional to the applied differential pressure. This places the MPXV2010DP within the hierarchy: pressure sensor -> transducer -> sensor -> MEMS -> semiconductor, and it is typically used in the signal-conditioning front end before an ADC. Key features include on-chip laser-trimmed span and offset calibration, integrated temperature compensation across 0 C to 85 C, and a fixed ratiometric 10 V nominal excitation that simplifies the analog front end. The dual-port same-side inlet accepts pneumatic manifolds via 3.3 mm tubes, and the ratiometric output allows system-level cancellation of supply-rail tolerances. The device uses a bipolar signal-conditioning interface; the differential bridge output is typically amplified externally by an instrumentation amplifier (e.g., a three-op-amp INA) before being digitized. Output impedance is approximately 1.7 kohm per side, so the amplifier input bias current must be kept low. Compared with board-mount ceramic capacitive sensors, piezoresistive parts offer higher bandwidth and lower cost but require thermal management of the self-heating error. Typical applications include HVAC variable-air-volume (VAV) flow sensing, medical respirator/inhaler airflow monitoring, industrial process-air differential measurement, and consumer appliance water-level detection. The combination of surface-mount packaging and on-chip compensation enables compact, low-BOM designs versus legacy through-hole MPX2010. When designing, set the ADC reference to the sensor supply voltage to fully exploit the ratiometric output and reject supply noise; route pneumatic tubing away from the package body to avoid stress-induced offset drift.

MPXV2010GP - 10kPa Vented Gauge Pressure Sensor | STMicroelectronics
The STMicroelectronics MPXV2010GP is a 10 kPa silicon piezoresistive pressure sensor in a surface-mount 8-SMD gull-wing package with a vertical side port. It provides a linear voltage output directly proportional to applied pressure, with the output span ratiometric to a 10 V supply (0 mV at 0 kPa to 25 mV at 10 kPa nominal), and is offered as a vented gauge configuration for cleanroom-side reference. A piezoresistive pressure sensor is a MEMS device in which a monolithic silicon diaphragm and an integrated strain-gauge resistor network convert mechanical pressure into a millivolt-level analog voltage. The MPXV2010GP sits in the hierarchy of: pressure transducer -> MEMS pressure sensor -> signal-conditioning sensor -> sensor IC. The on-chip thin-film resistor network is laser-trimmed for span, offset, and temperature compensation, which removes the need for external calibration and simplifies firmware-side linearization in host MCUs. Key features include a 0–10 kPa operating range, 25 mV full-scale span at 10 V excitation, 1.0 kPa typical pressure hysteresis, an integrated temperature compensation network, and ratiometric output that tracks supply voltage. The case 344B-01 package (8-SMD, gull-wing, side port) provides a robust surface-mount form factor with the pressure port on the package side, enabling vertical pneumatic coupling through a single 3.17 mm (0.13") tube barbed inlet. The MPXV2010GP uses a monolithic silicon diaphragm with a Wheatstone-bridge strain-gauge configuration; bridge excitation at 10 V DC produces a differential millivolt signal proportional to differential pressure. The trimming process calibrates each device at room temperature and 0/10 kPa, with downstream accuracy dependent on the chosen ADC resolution and reference, and on conditioning the output through an instrumentation amplifier before MCU sampling. Typical applications include HVAC differential pressure monitoring, medical respirators and ventilators, industrial process control, air-flow measurement in variable-air-volume (VAV) boxes, and low-pressure process instrumentation where 0–10 kPa sensing with a clean vented reference is required. The vented gauge reference makes the device well-suited to barometric-style measurements where backside absolute-pressure artifacts must be excluded. When designing with the MPXV2010GP, use a low-impedance instrumentation amplifier at the sensor output to preserve the mV-level signal and reject common-mode noise, and place a 0.01 uF bypass capacitor close to the supply pin. The output is ratiometric, so using a stable, low-noise 10 V reference yields the best full-scale accuracy. This page synthesizes distributor stock, drop-in same-package alternatives from the NXP MPX2010 family, and practical signal-conditioning design notes not found in the MPXV2010GP datasheet alone.
MPXV2053DP - 50kPa Differential Pressure Sensor | STMicroelectronics
The STMicroelectronics MPXV2053DP is a 50 kPa (7.25 PSI) differential piezoresistive pressure sensor housed in an 8-pin SOP (Small Outline Package) case with dual ports on the same side. It delivers a highly accurate, linear analog voltage output of 0 mV to 40 mV at the nominal 10 V supply, directly proportional to the applied differential pressure, and is factory laser-trimmed for precise span, offset calibration, and on-chip temperature compensation. What is a piezoresistive pressure sensor? It is a MEMS device in which microscopic strain gauges diffused into a silicon diaphragm change resistance when flexed by an external pressure differential. This resistance change is conditioned into a calibrated millivolt-level analog voltage that the host microcontroller or ADC can read directly. Pressure sensors of this type belong to the broader transducer family used wherever an electronic control loop must sense the physical state of a gas or liquid. Key features include 0 mV to 40 mV output span over the 0 kPa to 50 kPa differential range, a typical full-scale span of 0.8 mV/kPa at 10 V excitation, on-chip temperature compensation from 0 C to +85 C, and a 10 V nominal supply that can be extended to 16 V maximum for headroom. The integrated thin-film resistor network eliminates the need for external compensation components, simplifying the signal-chain design. The sensor uses a monolithic silicon diaphragm with an integrated strain gauge and thin-film resistor network. The piezoresistive bridges are laser-trimmed during production, giving factory-calibrated accuracy without user-side calibration. Designers feed the differential output directly into an instrumentation amplifier, or often rely on the device's own bridge topology when only moderate accuracy is required. Typical applications include medical respiratory equipment (e.g., ventilators), HVAC air-flow monitors, level measurement in non-corrosive fluids, industrial process controls, and consumer appliances such as washing machines requiring water-level feedback. When designing with this device, ensure a stable 10 V excitation rail and a low-offset instrumentation amplifier downstream of the bridge. The dual-port same-side package simplifies tubing routing in air-flow paths. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
MPXV2053GP - 50kPa Pressure Sensor | NXP | mV Output
The NXP MPXV2053GP is a 50 kPa on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor that delivers a highly accurate, linear voltage output directly proportional to applied pressure. Housed in an 8-SMD gull-wing package with a top-side port, the device operates from 0 to 50 kPa (0 to 7.25 PSI) in vented gauge configuration and produces a 0 mV to 40 mV differential output when driven from a 10 V supply, capturing pressure through a male 0.13" (3.17 mm) tube port. The "V" vent hole beside the port provides reference to atmospheric pressure for true gauge reading. A pressure sensor is a transducer that converts an applied physical pressure into a proportional electrical signal, used wherever a system must monitor or react to fluid or gas pressure. Within the broader taxonomy, the MPXV2053GP belongs to the sensor family, more specifically to piezoresistive (silicon strain-gauge) pressure sensors, and within that to the mV-output (uncompensated or partially compensated) subclass that requires an external signal-conditioning chain. Its on-chip temperature compensation and calibration distinguish it from bare die-strain elements, eliminating the need for external compensation circuits in many low-precision applications. Key features of the MPXV2053GP include factory calibration, on-chip temperature compensation over 0°C to +85°C, excellent linearity across the 0–50 kPa range, and very low hysteresis. The sensor uses a single axial port with a tube interface, allowing direct pneumatic connection to the manifold under test. The 8-SMD form factor supports automated assembly, and the top-side port orientation simplifies manifold design in vertical-mount pressure assemblies. Output is ratiometric to supply voltage, meaning a 5 V supply halves the full-scale output to about 20 mV. Typical applications include HVAC differential pressure sensing, medical inhalation and respiratory monitoring equipment, industrial process control and level measurement, altimeters and barometric instruments, and pneumatic control in fuel-cell and analytical instruments. The 50 kPa full-scale range is well suited to low-pressure gas and dry-air measurements where differential pressures span a few kPa up to nearly 1 atm of gauge pressure. When designing with this part, plan for a low-noise, high-gain instrumentation amplifier (such as an INA125 or AD620 with gain of about 100) because the native 40 mV full-scale output is too small for direct ADC digitization in 12-bit systems. Provide adequate PCB isolation between the digital ground and the analog ground star-point near the sensor’s ground pins to avoid corrupting the small millivolt signal.
MPXV2102DP - 100kPa Differential Pressure Sensor 8-BSOP | NXP
The NXP MPXV2102DP is a 100 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor housed in an 8-BSOP (0.475" / 12.06 mm width) package with dual ports on the same side, differential pressure type. The device delivers a linear analog output of 0 mV to 40 mV at 10 V excitation, operates from -40 C to +125 C, and is rated for 14.5 PSI (100 kPa) differential pressure measurement. A piezoresistive pressure sensor is a MEMS device that converts applied pressure into a small differential voltage by changing the resistance of strain-sensitive silicon resistors diffused into a diaphragm. NXP's MPX series adds on-chip temperature compensation and laser-trimmed calibration, so the output remains linear and stable across the full operating range without external trimming. In the broader hierarchy, this places the MPXV2102DP as a board-mount pressure transducer (sensor -> transducer -> sensor) -> MEMS pressure sensor -> signal-conditioning IC family. The 'V' in MPXV2102DP indicates the dual-port BSOP package variant, distinct from the single-port 'G' and 'GP' variants in the family. Key features include 0 mV to 40 mV full-scale span at 10 V excitation, differential sensing with two side-by-side ports for gauge-reference applications, integrated temperature compensation from 0 C to 85 C, and ratiometric output that scales with supply voltage. The 8-BSOP package has vertical port orientation for through-hole-style pressure attachment, making it suitable for manifolds and enclosures where tubing enters from one direction. The architecture combines a silicon strain gauge bridge with a thin-film resistor network that cancels temperature-induced span and offset drift. The output impedance is nominally 1.1 kohm and the bridge is designed for 10 V typical excitation (max 16 V), giving designers flexibility to trade signal amplitude against self-heating. The on-chip compensation removes the most costly external analog circuitry previously required in discrete pressure-sensor designs. Typical applications include medical respiratory monitoring, HVAC variable-air-volume (VAV) controls, industrial process pneumatic monitoring, altimeters and barometric instrumentation, and appliance water-level detection. In respiratory monitoring, the differential configuration measures airflow across a Venturi or flow-restriction element, while in VAV controllers it measures duct static pressure to regulate damper position. In each case the 40 mV full-scale span pairs naturally with an instrumentation amplifier such as the NCS3330 to deliver a clean 0-5 V or 4-20 mA output. When designing with this part, choose an instrumentation amplifier with low offset (under 50 uV), low noise, and high CMRR. Place the sensor close to the amplifier to avoid injecting noise into the high-impedance bridge output, and add RC low-pass filtering at the amplifier input to bandlimit acoustic and EMI noise. Use a regulated low-noise 10 V reference such as the NCP1117 or a precision reference for best ratiometric accuracy.
