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.

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. This page synthesizes cross-brand equivalents, drop-in alternatives, and application-level design notes not found in a single distributor listing, providing information gain beyond the manufacturer datasheet.
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.

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. This page synthesizes distributor pricing, drop-in alternatives from the same MPX product family, and practical design notes for instrumentation amplifier pairing not found in the manufacturer datasheet alone.
MPXV2102GP - 100 kPa Gage Pressure Sensor | NXP
The NXP MPXV2102GP is a 100 kPa on-chip temperature compensated silicon piezoresistive pressure sensor in an 8-pin SOP (case 1735) gull-wing package with a vertical/axially-oriented pressure port on the side of the package. It provides a linear, calibrated voltage output of 0 mV to 40 mV (typical) over a 0 kPa to 100 kPa (0-14.5 PSI) gage pressure range when excited with a 10 V DC supply, and operates as a vented-gauge sensor referenced to ambient atmosphere through the side port. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a MEMS device in which four silicon strain gauges arranged in a Wheatstone bridge on a flexible diaphragm change resistance proportionally to applied pressure. Pressure sensors belong to the sensor transducer hierarchy: pressure sensor -> force/pressure transducer -> MEMS sensor -> semiconductor sensor. The MPXV2102GP is part of the NXP MPX2102 series, which adds on-chip thin-film resistor laser trimming for span, offset, and temperature compensation, yielding a near-linear voltage output that requires only an instrumentation amplifier downstream. Key features include a pressure range of 0 kPa to 100 kPa (0-14.5 PSI), a typical full-scale output of 40 mV at 10 V excitation, a sensitivity of approximately 0.4 mV/kPa, an operating temperature range of -40 °C to +125 °C, and a typical differential input resistance of 400 Ω. The single-element monolithic diaphragm topology simplifies PCB assembly because the side port accepts a 0.13" (3.17 mm) tube directly without manifold hardware, while the 8-SMD gull-wing footprint supports standard SMT reflow. Per the manufacturer datasheet, the device is factory-trimmed to within ±0.25% of span at 25 °C. Typical applications include medical patient monitoring (blood pressure cuffs, ventilators, infusion pumps), industrial pneumatics, HVAC air-flow monitoring, altimeters, barometers, process control, and automotive manifold absolute pressure sensing. Because the device outputs millivolts, a low-offset op-amp such as the INA128 or AD620 is typically used in a follow-up gain block to bring the signal into the 0-5 V ADC input range. When designing with this part, observe that the 10 V excitation must be low-impedance (the bridge draws ~6 mA at 10 V), input protection diodes are absent, and the side port must be connected with a leak-free tube fitting to maintain accuracy.
MPXV2202DP - 200 kPa Differential Pressure Sensor, 8-BSOP | STMicroelectronics
The NXP Semiconductors (formerly Motorola) MPXV2202DP is a 200 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor in an 8-BSOP (Super-Body Small Outline Package) with dual port pressure inlet. It delivers a highly accurate, linear differential voltage output directly proportional to the applied pressure, operates on a 10 V supply (Vs), and produces a 0 mV to 40 mV full-scale span across 0 kPa to 200 kPa (0 PSI to 29.01 PSI). According to the manufacturer datasheet, the device uses a single piezoresistive strain-gauge bridge that is laser-trimmed and temperature-compensated, removing the need for external calibration components in most applications. A piezoresistive pressure sensor is a MEMS device in which diffused silicon resistors change resistance when mechanical strain is applied to a diaphragm. The MPXV2202DP belongs to the pressure sensor family within the broader sensor hierarchy (sensor -> transducer -> MEMS -> semiconductor). Piezoresistive sensors differ from capacitive or resonant types by offering a simple ratiometric analog voltage output that is easy to read with any ADC, at the cost of slightly higher noise and lower absolute accuracy than capacitive alternatives. They are typically used where cost, linearity, and DC response matter more than ppm-level precision. Key features include 0 mV to 40 mV output span over 0 to 200 kPa, 0.25% typical linearity (best-fit straight line), ±0.5% full-scale span temperature error over 0°C to 85°C, 5 kHz frequency response, and an operating temperature range of -40°C to +125°C. The sensor is differential (two ports on the same side of the package), allowing either gauge or differential measurements depending on how the ports are connected. The 8-BSOP housing has a thermal resistance suitable for direct PCB mounting in industrial environments, and the on-die compensation eliminates the need for external thermistor networks. The device integrates a Wheatstone bridge of four piezoresistors diffused into a silicon diaphragm. When pressure is applied across the dual ports, the diaphragm flexes and unbalances the bridge, producing a differential voltage that scales linearly with applied differential pressure. The on-chip thin-film resistors perform gain and offset calibration, while proprietary temperature compensation corrects the span and offset drift across the operating range, producing a near-plug-and-play analog pressure output that interfaces directly with instrumentation amplifiers or ADC front-ends. Typical applications include medical ventilators and respiratory monitoring, HVAC differential pressure measurement, industrial process control, analytical instruments, and tire pressure monitoring. The differential port configuration also makes the part useful in flow measurement when paired with a laminar flow element (Pitot tube or orifice plate). Its dual-port same-side form factor simplifies hose connection in medical equipment where tubing geometry is constrained. When designing with the MPXV2202DP, note that the 40 mV full-scale span requires an instrumentation amplifier with low offset drift (such as the INA128 or AD620) to reach usable system-level resolution. Place 100 nF ceramic bypass capacitors on the supply pins and route sensor grounds in a star configuration with the amplifier ground to avoid digital noise injection. For medical applications, verify media compatibility because the datasheet only characterizes dry air operation.

MPXV2202GC6T1 - 200kPa Vented Gauge Pressure Sensor | NXP/ST
The NXP (formerly Freescale, now under STMicroelectronics distribution) MPXV2202GC6T1 is a piezoresistive pressure sensor providing a linear analog output of 0 mV to 40 mV at 10 V supply over a 0 kPa to 200 kPa (0 PSI to 29.01 PSI) vented gauge pressure range, housed in an 8-SMD gull-wing top-port surface-mount package. The sensor uses on-chip temperature compensation and calibration, delivering a highly accurate voltage directly proportional to the applied pressure. The top-port 0.13 inch (3.17 mm) tube inlet accepts a barbed pressure fitting, while the vented-gauge reference accommodates applications where one side of the diaphragm is exposed to atmospheric pressure via the package vent. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a MEMS device in which diffused silicon strain gauges (Wheatstone bridge) change resistance when mechanical stress is applied to a silicon diaphragm, producing a differential output voltage proportional to pressure. Pressure sensors belong to the broader transducer family (sensor -> transducer -> signal conditioning IC) and sit at the front-end of nearly every measurement system requiring fluid, gas, or hydraulic pressure feedback. Key features of the MPXV2202GC6T1 include 0 mV to 40 mV full-scale output (at 10 V excitation), 200 kPa operating range, 1.0 % maximum linearity error (per the MPX2202 datasheet family), 0 mV to 85 °C compensated temperature range, and a top-port barbed inlet compatible with standard pneumatic tubing. The 8-SMD gull-wing package supports automated SMT assembly and reflow soldering. Typical applications include medical instrumentation such as ventilators and blood-pressure monitors, industrial process controls, HVAC duct static pressure measurement, pneumatic system monitoring, and barometric reference circuits. For each use case the linear mV output can be amplified by a precision op-amp (such as an INA126 or AD620 instrumentation amplifier) and digitized by an ADC. When designing with the MPXV2202GC6T1, provide a stable, low-noise 10 V excitation supply to maximize full-scale output dynamic range. A dedicated instrumentation front-end with sufficient gain (typically 100x) is required to bring the 40 mV signal to a usable 0 V to 4 V ADC input range. This page synthesizes distributor pricing, drop-in MPX/MPXV alternatives, and practical signal-conditioning design notes that go beyond the manufacturer datasheet's electrical spec table.
MPXV2202GP - 200 kPa Vented Gauge Pressure Sensor | NXP
The NXP MPXV2202GP is a 200 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor packaged in an 8-pin SO (SOP-8) body with a side-mounted vertical port, supplied by NXP Semiconductors. It produces a differential analog voltage output of 0 mV to 40 mV at a 10 V supply that is linearly proportional to applied gauge pressure, and its vented gauge configuration references pressure relative to ambient through the side port. With a 0 to 200 kPa (0 to 29.01 psi) operating range and 0.2 mV/V sensitivity, it integrates on-chip temperature compensation and laser-trimmed calibration so that no external compensation network is required. A piezoresistive pressure sensor is a MEMS device in which a diaphragm etched into a silicon substrate flexes under applied pressure, changing the resistance of four implanted piezoresistors arranged in a Wheatstone bridge; the bridge produces a differential output voltage proportional to pressure. Piezoresistive sensors belong to the broader category of pressure transducers, which in turn are a sub-family of sensors alongside temperature, motion, and flow sensors. Pressure sensors are foundational in industrial process control, medical instrumentation, HVAC, and automotive systems, where they translate mechanical pressure into precision electrical signals that a microcontroller or instrumentation amplifier can digitize. Key features of the MPXV2202GP include 0 mV to 40 mV output span at 10 V excitation, 0.2 mV/V nominal sensitivity, on-chip temperature compensation across 0 to 85 C, and a vented gauge reference that lets the part measure pressure relative to atmosphere. The integrated Wheatstone bridge plus laser-trimmed resistors deliver calibrated accuracy without external compensation components. The SOP-8 case style, also referred to as SO-8 or SO8 with small-outline plastic body measuring 12.06 mm x 12.06 mm x 8.38 mm with 2.54 mm pitch, supports surface-mount assembly and provides a robust mechanical port that simplifies pneumatic connection. Typical applications include medical respiratory monitors, HVAC blower and filter monitoring, industrial pneumatic controls, and low-pressure process instrumentation. Designers use it where a calibrated, linear, ratiometric analog output is preferred over digital sensor ICs. The device is drop-in compatible with other members of the MPX2202/MPXV2202 family, simplifying board-level reuse across product variants. When designing with this part, ensure a stable low-noise 10 V excitation source and a high-gain instrumentation amplifier (such as INA128 or AD620) on the output, because the native 40 mV full-scale signal must be amplified to interface with typical 0 to 5 V ADC inputs. A small RC low-pass filter (typically 1 kohm plus 0.01 uF) at the output limits EMI and aliasing before digitization.

The STMicroelectronics MPXV4006DP is a monolithic piezoresistive differential pressure sensor with a 0 to 6 kPa (0 to 0.87 psi) full-scale range, providing a ratiometric analog output of 0.2 V to 4.7 V from a single 5 V supply. Housed in an 8-BSOP (0.475" / 12.06 mm width) package with dual tube ports on the same side, the device integrates on-chip signal conditioning, temperature compensation, and factory calibration, allowing direct connection to a microcontroller ADC without external compensation circuitry. A piezoresistive pressure sensor is a MEMS device in which diffused silicon strain gauges form a Wheatstone bridge on a micromachined diaphragm; when differential pressure is applied across the diaphragm, the bridge outputs a voltage proportional to the applied pressure. Piezoresistive sensors sit within the broader category of silicon pressure transducers, which in turn belong to the MEMS (micro-electromechanical systems) sensor family used in industrial, consumer, healthcare, and appliance applications. The MPXV4006DP combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing to deliver a calibrated analog signal. Key specifications include a 5 V typical supply voltage (4.75 V to 5.25 V range), 0.2 V to 4.7 V output span, sensitivity of approximately 766 mV/kPa, and an operating temperature range of -10 °C to +60 °C. The differential configuration measures the pressure difference between two ports on the same side of the package, making it suitable for flow-based measurements where one port references ambient pressure. The 8-BSOP surface-mount package simplifies PCB assembly while preserving the dual-port pneumatic connection. Typical applications include HVAC variable-air-volume (VAV) controllers, respiratory monitoring equipment, weather station barometric pressure measurement, and industrial process monitoring. The wide 4.7 V full-scale output swing maximizes ADC resolution when sampled by 5 V-tolerant microcontroller ADCs. The integrated temperature compensation maintains accuracy across the operating range without external calibration. When designing with this part, route the analog output trace away from switching noise sources and add a small RC filter near the ADC input to suppress high-frequency noise. The dual-port package requires a pneumatic manifold or flexible tubing for the pressure source, and the gel-filled port design protects the die from humid and mildly contaminated media. This page combines manufacturer specifications, drop-in alternative cross-references, and practical design guidance not aggregated on typical distributor product listings.

MPXV4006G6U - 0.87 PSI Vented Gauge Pressure Sensor | NXP Semiconductors
The NXP Semiconductors MPXV4006G6U is an integrated silicon pressure sensor that delivers a calibrated, temperature-compensated analog output proportional to applied differential or vented gauge pressure in the 0 to 0.87 PSI (0 to 6 kPa) range. The device combines a piezoresistive transducer die with on-chip signal conditioning, providing a near-rail-to-rail ratiometric output of 0.2 V to 4.7 V from a single 5 V supply in an 8-SMD gull-wing top-port package. A piezoresistive pressure sensor is a MEMS device in which a diaphragm with embedded strain gauges deflects under pressure, changing its resistance in a Wheatstone bridge that converts mechanical force into a millivolt-level electrical signal. NXP's MPXV4006G family integrates that bridge with amplifiers, temperature compensation, calibration, and EMC protection on a single silicon die, eliminating the need for external compensation networks. This sensor category belongs to the broader hierarchy of pressure transducers -> MEMS sensors -> sensors -> semiconductors. Key features include a 0.2 V to 4.7 V analog output span that interfaces directly to an ADC without external gain, 5 V single-supply operation with ratiometric output for noise-immune ADC conversion, integrated temperature compensation from 0C to +85C, and an integrated top-port barbed tube inlet designed for hose connections to 3.17 mm (1/8 inch) tubing. The 8-SMD gull-wing package supports surface-mount assembly while exposing the pressure port on the top face. Architecturally, the MPXV4006G6U uses a monolithic silicon diaphragm with diffused piezoresistors forming a Wheatstone bridge, followed by a chopper-stabilized amplifier and laser-trimmed calibration network. This topology delivers a typical accuracy of ±0.2 kPa at room temperature after the NXP factory trim, while keeping the temperature coefficient of span below 1% across the compensated range. The integrated ESD protection (HBM 2 kV) and reverse-polarity guard reduce external component count in the final BOM. Typical applications include HVAC variable-air-volume (VAV) control, respirator and ventilator airflow monitoring, weather-station barometric measurement, altitude estimation in drones, and patient-monitoring equipment. In each case the 6 kPa full-scale and 0.2 V-4.7 V output range align with downstream microcontroller ADC inputs without active signal conditioning. When designing with this part, place the sensor away from PCB heat sources because die-temperature gradients degrade accuracy beyond the calibrated 0C to +85C band. Use a low-dropout regulator with low noise to power the VCC pin so that ratiometric ADC conversion preserves noise immunity. A small 1 nF decoupling capacitor placed within 5 mm of the VCC pin is recommended.

The NXP MPXV4006G7U is an integrated silicon piezoresistive pressure sensor that delivers a conditioned, temperature-compensated analog voltage output proportional to applied gauge pressure in the 0 kPa to 6 kPa (0 to 0.87 PSI) range. The device operates from a single 4.75 V to 5.25 V supply, provides a 0.2 V to 4.7 V ratiometric output, and is housed in an 8-pin DIP-style through-hole module with a single axial pressure port (no port variant). The monolithic transducer combines an on-chip Wheatstone bridge, signal conditioning ASIC, calibration EEPROM and temperature compensation, eliminating the need for external compensation components. What is a vented gauge pressure sensor? A vented gauge (or gage) pressure sensor measures pressure relative to ambient atmospheric pressure through a vent tube or port. In the broader taxonomy, vented gauge sensors belong to gauge pressure sensors, which are a subclass of differential pressure sensors. Differential pressure sensors sit inside the wider category of MEMS pressure sensors, which themselves are part of the silicon transducer family used in modern sensor and IoT systems. Vented gauge sensors are commonly used to derive barometric-corrected absolute measurements because the reference side of the diaphragm is exposed to ambient air. Key features of the MPXV4006G7U include ±5% accuracy across the compensated pressure range, on-chip temperature compensation from -10 °C to +60 °C, ±1.5% maximum pressure range tolerance, and an analog ratiometric output that simplifies ADC interfacing. The 0.2 V to 4.7 V swing uses nearly the full 0 V to 5 V input range of typical microcontrollers, maximizing dynamic resolution. The 8-pin DIP package offers through-hole mounting for hand-soldered prototypes and easy integration with breadboards. Architecturally, the sensor uses a silicon micromachined diaphragm with an embedded piezoresistive bridge; strain generated by pressure deflection modulates bridge resistance, and the on-chip ASIC amplifies and calibrates this signal. Calibration coefficients are stored on-chip, removing the need for external trim networks and enabling part-to-part interchangeability within ±5%. Typical applications include weather stations, HVAC duct pressure monitoring, medical respiratory equipment, altimeters, tire pressure gauges, and altitude-correcting barometric instruments. Designers select this part when a calibrated, temperature-compensated, low-pressure analog sensor is needed without the burden of external signal conditioning. When designing with the MPXV4006G7U, place a 0.1 µF decoupling capacitor close to the supply pin and route the analog output through a low-pass filter if the application involves high-frequency electrical noise. The vent port must remain unobstructed to preserve gauge-reference accuracy. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers select and qualify the part quickly for embedded and instrumentation designs.

The STMicroelectronics MPXV4006GC6T1 is a monolithic piezoresistive silicon pressure sensor providing a calibrated, temperature-compensated analog output proportional to applied pressure. It measures 0 to 6 kPa (0 to 0.87 PSI) vented gauge pressure through a top-mounted 0.13" (3.17 mm) tube port and outputs an analog voltage from 0.2 V to 4.7 V on an 8-pin SMD gull-wing package designed for surface-mount assembly. A pressure sensor is a transducer that converts a physical pressure input into a measurable electrical signal, usually an analog voltage proportional to the applied force per unit area. The MPXV4006GC6T1 belongs to the integrated silicon pressure sensor sub-family of MEMS sensors, sitting within the broader sensor hierarchy: pressure sensor -> transducer -> sensor -> semiconductor. On-chip signal conditioning and bipolar processing deliver an accurate, high-level analog output suitable for direct connection to a microcontroller ADC without external amplification, distinguishing it from raw bridge-type sensors that require external compensation. Key features include 0 to 6 kPa operating range with 5.0 V typical supply, on-chip temperature compensation and calibration from 0 to 85 C, low power consumption of approximately 6 mA, and ratiometric analog output. The SOP 8 gull-wing top-port package integrates a vertical tube inlet that simplifies plumbing in medical and consumer pneumatic assemblies while keeping the PCB footprint compact. The architecture combines advanced micro-machining, thin-film metallization, and bipolar signal conditioning to produce a self-contained sensing module. Ratiometric output means the output voltage scales linearly with supply voltage, allowing direct interface to 3.3 V or 5 V ADCs. The integrated temperature compensation rejects thermal drift across the 0 to 85 C compensation range. Typical applications include spirometry and respiratory equipment, HVAC variable-air-volume controls, weather station barometric measurement, appliance pressure monitoring, and consumer fitness devices. Industrial uses extend to tank level sensing, filter monitoring, and process control loops where a clean differential pressure indication is required. Designers should provide adequate tube sealing to prevent leakage or contamination entering the port and route analog output traces away from switching converters. The device requires a stable 5 V supply because output is ratiometric, meaning supply noise couples directly into the measurement.
MPXV4006GC6U - 6 kPa Gauge Pressure Sensor, 5V, SOP-8 | NXP
The NXP MPXV4006GC6U is an integrated silicon piezoresistive pressure sensor delivering a calibrated, temperature-compensated analog output from 0.2 V to 4.7 V across a 0 kPa to 6 kPa (0 to 0.87 PSI) gauge pressure range, housed in an 8-SMD gull-wing top-port package. According to the NXP MPXV4006G datasheet, it operates from a single 5 V supply and provides a near-linear transfer function suited for microcontroller ADC input. A pressure sensor is a transducer that converts an applied pressure into a measurable electrical signal. Piezoresistive sensors achieve this by exploiting the change in resistance of silicon strain gauges diffused into a diaphragm; when pressure deflects the diaphragm, the resistors form a Wheatstone bridge whose differential output is proportional to pressure. On-chip signal conditioning, calibration, and temperature compensation in the MPXV4006GC6U eliminate the need for external analog circuitry, which is a key reason this part dominates in cost-sensitive medical, consumer, and HVAC designs. Key features of the MPXV4006GC6U include a 0 kPa to 6 kPa operating range, ratiometric analog output, 5 V single-supply operation, and top-port 1/8 inch tube pressure inlet. The 8-SMD gull-wing package supports surface-mount assembly, while the integrated compensation delivers typically ±1.5% accuracy over 0°C to 85°C. The sensor also provides a 10 ms typical response time, enabling real-time pressure tracking in dynamic flow systems. Technically, the MPXV4006G family uses a monolithic silicon die combining the mechanical diaphragm and the analog ASIC in a single chip. This co-integration reduces long-term drift compared with hybrid assemblies and enables a small footprint with high reliability. The 0.2 V to 4.7 V swing keeps the signal well within the 5 V ADC input range of common microcontrollers such as the NXP Kinetis and S32K families. Typical applications include respiratory monitoring in medical devices, HVAC differential pressure sensing, air-flow measurement in variable-air-volume boxes, appliance water-level detection, weather-station barometric compensation, and process-control gauge monitoring. The integrated signal path allows designers to read pressure with a single ADC channel and minimal firmware calibration. When designing with this part, route the top-port tube away from vibration sources and PCB flexure, and add a small RC filter on the VOUT node if the ADC input is high-impedance to attenuate conducted EMI. Decouple the supply with a 0.1 µF ceramic capacitor placed within 5 mm of the VCC pin.
MPXV4006GC7U - 6kPa Vented Gauge Pressure Sensor | STMicroelectronics
The STMicroelectronics MPXV4006GC7U is a monolithic piezoresistive pressure sensor providing a calibrated, temperature-compensated analog output proportional to applied differential pressure, ranging from 0 to 6 kPa (0.87 PSI), in an 8-pin DIP package with a top-side vertical pressure port. The transducer operates from a single 5 V supply and produces a ratiometric output voltage spanning approximately 0.2 V (at 0 kPa) to 4.7 V (at 6 kPa), with on-chip signal conditioning, calibration, and temperature compensation. A piezoresistive pressure sensor is a MEMS device in which a diaphragm fabricated on a silicon substrate deflects under applied pressure, changing the resistance of piezoresistors arranged in a Wheatstone bridge. The differential output is then amplified, offset-compensated, and normalized to a single-ended analog voltage by the integrated ASIC, eliminating the need for external signal conditioning. Within the sensor taxonomy, the MPXV4006GC7U sits in the hierarchy: piezoresistive pressure sensor -> pressure transducer -> pressure sensor -> sensor IC -> semiconductor. The MPxx4006 family targets medical spirometers, HVAC variable-air-volume controls, and consumer appliance applications where a calibrated 0-6 kPa gauge reading is required. Key features include a full-scale span of 6 kPa, an accuracy of ±1.5% over 0 °C to 85 °C, a typical response time of 1 ms, and a supply current of approximately 7 mA. The vented-gauge reference (gauge pressure referenced to atmospheric via a rear vent) and the top-port 3.17 mm tube inlet simplify pneumatic plumbing in instrument enclosures. Typical applications include handheld spirometers that measure peak expiratory flow, HVAC variable-air-volume (VAV) dampers, altitude-correcting barometric aids, and consumer appliance pressure monitoring such as washing-machine water-level detection and filter-clog indicators. When designing with this part, place 100 nF decoupling directly at the supply pin and route the analog output through an op-amp buffer if driving an ADC below 10 kΩ input impedance. Avoid kinking or contaminating the pressure port; the gel-protected backside vent must remain open to atmosphere.
MPXV4006GP - 6kPa Vented Gauge Pressure Sensor SOP-8 | NXP
The NXP MPXV4006GP is a monolithic silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, housed in an 8-pin Small Outline Package (SOP-8) with a side-mounted barbed port. It operates from a single 5V supply, accepts a vented gauge pressure range of 0 to 6 kPa (0 to 0.87 psi), and produces an analog ratiometric output of 0.2 V to 4.7 V proportional to applied pressure. A pressure sensor converts an applied differential or absolute pressure into an electrical signal. Vented gauge types like the MPXV4006GP use a reference vent on the back side of the die, so the output reflects pressure relative to atmospheric pressure rather than a sealed vacuum. The MPXV4006G series targets medical, consumer, and industrial devices and falls within the broader sensor category of micro-electro-mechanical systems (MEMS), which combine mechanical diaphragms and silicon signal processing. Key specifications include a typical full-scale span of 4.5 V (from 0.2 V at 0 kPa to 4.7 V at 6 kPa), an accuracy of ±5 percent, a temperature compensation range of 10°C to 60°C, and an operating temperature range of -10°C to 60°C. The internal ASIC amplifies and corrects the raw Wheatstone-bridge output, so no external calibration circuitry is required. The sensor uses a piezoresistive bridge whose resistance changes when the diaphragm deflects under pressure; the die reference vent stabilizes the offset against changes in atmospheric pressure. The factory-trimmed output eliminates the need for customer gain or offset adjustment. Typical applications include medical CPAP and ventilator airflow monitoring, HVAC air-flow measurement, air-handling equipment, weather-station barometers, and consumer spirometers. The ratiometric analog output is compatible with most microcontroller ADC inputs. Design consideration: keep the side port free of debris, route the analog trace away from switching regulators, and add an RC low-pass filter at the MCU ADC input if the application contains switching noise. The trade-off compared to digital-output sensors is simpler MCU interface versus no built-in signal conversion. This page synthesizes distributor availability, drop-in alternatives, and design notes not always covered in the manufacturer datasheet, helping engineers quickly assess fit for pressure-sensing designs.
MPXV4115V6U - -115 kPa Vacuum Pressure Sensor, 0.2-4.6V | NXP
The NXP MPXV4115V6U is an integrated silicon piezoresistive pressure sensor that delivers a calibrated analog output from 0.2 V to 4.6 V for vacuum pressure measurements from -115 kPa to 0 kPa (-16.68 PSI to 0 PSI). Housed in an 8-SMD gull-wing surface-mount module, the part combines a monolithic silicon sense die with on-chip bipolar op-amp signal conditioning, thin-film resistor networks, and factory calibration so that no external compensation network is required at the system level. A single 5 V supply (4.75 V to 5.25 V) powers both the sensor bridge and the output stage. An integrated silicon pressure sensor (also called a piezoresistive pressure transducer or MEMS pressure sensor) is a monolithic device that converts applied pressure into a proportional electrical signal by exploiting the piezoresistive effect in doped silicon strain gauges diffused onto a diaphragm. The MPXV4115V6U belongs to the broader sensor hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor IC -> semiconductor. Compared to ceramic capacitive or stainless-steel strain-gauge modules, integrated silicon sensors offer tighter factory calibration, lower per-unit cost at volume, and a smaller PCB footprint, at the trade-off of narrower temperature tolerance and limited media compatibility. Key specifications include an operating pressure range of -16.68 PSI to 0 PSI (-115 kPa to 0 kPa), a maximum overpressure rating of -58.02 PSI (-400 kPa), an output span of 0.2 V to 4.6 V (approximately 38.3 mV/kPa), and a typical accuracy of ±1.5% Vfss. The on-chip temperature compensation flattens the output across the rated operating temperature range, and the integrated amplifier yields a low-impedance ratiometric output that interfaces directly to an MCU ADC. The -V suffix denotes the vacuum-gauge variant; non-V siblings cover 0 to +115 kPa positive gauge pressure. Typical applications include medical respiratory monitoring, HVAC vacuum measurement, altimeter/barometric reference, industrial vacuum-pump diagnostics, and engine manifold absolute pressure (MAP) sensing when biased against atmosphere. The 8-SMD gull-wing package simplifies pick-and-place assembly and supports automated optical inspection, while the calibrated output removes counter design requirements and external trim potentiometers. When designing with this part, place 0.1 uF decoupling close to the supply pin and route the analog output away from switching traces to preserve the 1.5% accuracy. The sensor is intended for clean, dry, non-corrosive gases; for liquid media or aggressive chemicals a protective media-isolated housing is required.

The device is housed in a surface-mount SOP-8 (8-SMD, Gull Wing, Top Port) package with an integrated 0.13 inch (3.17 mm) pressure port for direct manifold attachment. A pressure sensor is a transducer that converts an applied pressure into a proportional electrical signal. The MPXV4115V series belongs to the broader piezoresistive sensor family, in which diffused silicon strain gauges arranged in a Wheatstone bridge change resistance when the diaphragm deflects under pressure. STMicroelectronics integrates bipolar op-amp signal conditioning, thin-film calibration resistors, and temperature compensation on the same silicon die, producing a high-level, microcontroller-ready analog output without external compensation circuitry. Key specifications include a 5 V nominal supply (4.85 V to 5.35 V operating range), 10 ms response time, ±2.5% maximum pressure error over 0 C to 85 C with calibration, and an on-chip temperature compensation range of -40 C to +125 C. The integrated op-amp chain amplifies the millivolt-level bridge signal to a 0.2 V to 4.6 V ratiometric swing that interfaces directly with an ADC input. The SOP-8 small-outline package with top-side port simplifies PCB layout and allows conformal coating without occluding the inlet. Typical applications include automotive manifold absolute pressure (MAP) sensing, barometric altimeters, weather stations, vacuum process monitoring, and HVAC system pressure measurement. The vacuum-variant V suffix targets applications that sense sub-atmospheric pressure, such as engine intake manifold vacuum, while the companion MPX4115A series addresses absolute pressure from 15 kPa to 115 kPa for similar signal-chain use cases. Designers should place a 0.1 uF decoupling capacitor close to the supply pin and use ratiometric ADC sampling tied to the same 5 V reference as the sensor supply to cancel reference drift. The top-port inlet accepts a 3.17 mm (1/8 inch) flexible tube; tubing must be airtight and free of kinks to preserve accuracy. Avoid exposing the port to condensing moisture without a hydrophobic filter. This page synthesizes distributor pricing, same-package drop-in alternatives, and application-specific design notes not consolidated in the manufacturer datasheet, helping engineers evaluate the MPXV4115VC6U for manifold vacuum, altimeter, and process-vacuum applications.
MPXV5004DP - 0-3.92kPa Differential Pressure Sensor | NXP
The NXP MPXV5004DP is a monolithic silicon piezoresistive pressure sensor that measures differential pressure from 0 to 3.92 kPa (0 to 0.57 PSI) and provides a calibrated, temperature-compensated analog output from 1 V to 4.9 V at 5 V supply. Housed in an 8-BSOP (CASE 1351-01) surface-mount package with two side-by-side male tube ports (3.3 mm O.D.), it integrates an implanted strain gauge, thin-film metallization, and bipolar signal conditioning on a single die. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a transducer that converts applied pressure into a change in resistance of diffused strain gauges on a silicon diaphragm, then conditions the resulting Wheatstone bridge imbalance into a proportional analog voltage. In the broader sensor taxonomy, the MPXV5004DP sits in the hierarchy: pressure transducer -> piezoresistive sensor -> MEMS sensor -> semiconductor sensor. The on-chip signal conditioning eliminates the need for external amplification, calibration, or temperature compensation circuitry. Key features include a 1.0 V to 4.9 V ratiometric analog output spanning the 0-3.92 kPa range, 5 V typical supply operation (max 5.25 V), and an operating temperature range of 0°C to +85°C. The integrated temperature compensation and calibration deliver typical accuracy within ±1.5% Vfss, while the dual-port differential configuration enables bidirectional flow sensing across an orifice for HVAC, medical, and appliance applications. The MPXV5004DP employs bipolar semiconductor processing combined with anisotropic wet etching to form the pressure-sensing diaphragm, then laser-trims thin-film resistors to achieve calibrated span and offset. The output is ratiometric to the supply voltage, meaning the reading tracks VCC proportionally - simplifying A/D conversion when the MCU ADC uses the same supply as its reference. Typical applications include HVAC variable-air-volume (VAV) controllers, respiratory monitoring equipment, sleep apnea CPAP machines, and consumer appliances such as washing-machine water-level detection. The wide 0-3.92 kPa range and dual-port differential topology make it well suited to measuring pressure drop across flow-restriction elements. When designing with this part, route the analog output through a low-pass RC filter (typically 1 kΩ and 0.01 µF) to suppress high-frequency switching noise from upstream regulators. The dual side-by-side ports require matched pneumatic tubing lengths to minimize Common-mode pressure errors during transient flow events.

Key features include 1 V to 4.9 V ratiometric analog output, 2.5% typical accuracy over 0C to 85C, on-board temperature compensation and calibration eliminating the need for external compensation circuits, and a robust surface-mount 8-SMD gull-wing package. The sensor operates from a single 5 V supply (4.75 V to 5.25 V) and is qualified for industrial and consumer applications. Its integrated signal path delivers a calm, low-noise analog output suitable for direct sampling by a 10-bit or 12-bit ADC. The MPXV5004G6U uses a monolithic silicon die combining an implanted strain gauge Wheatstone bridge with thin-film metallization, on-chip CMOS signal conditioning, and laser-trimmed calibration. This integration delivers a calibrated output over temperature without external trimpots, reducing bill-of-materials count and assembly time. The 8-SMD module format isolates the sensing element from PCB stress to preserve long-term accuracy, while the integrated port provides repeatable pneumatic interfacing. Typical applications include HVAC variable-air-volume (VAV) control, medical spirometers and respiratory instruments, level measurement of non-corrosive gases and liquids, weather station barometric pressure trend monitoring, and consumer appliance airflow sensing. The 3.92 kPa range targets low-pressure differential applications rather than high-pressure industrial systems. When designing with this part, place a 0.1 uF decoupling capacitor close to the supply pin and route analog output traces away from switching converters. Avoid mechanical stress on the package body and follow NXP's recommended port tubing procedures to prevent measurement drift. Note that the sensor is calibrated at 5 V operation and accuracy will degrade at lower supply voltages.
