MPXV5004G7U - 3.92kPa Vented Gauge Pressure Sensor | NXP
The NXP MPXV5004G7U is an integrated piezoresistive pressure sensor that delivers a calibrated, temperature-compensated analog output of 1.0 V to 4.9 V over a 0 to 3.92 kPa (0 to 0.57 PSI) vented gauge pressure range, housed in an 8-DIP through-hole module. What is a gauge pressure sensor? A gauge pressure sensor measures pressure relative to atmospheric pressure through a vented reference port, which is essential for applications where absolute atmospheric pressure would distort the reading. In the broader sensor hierarchy, gauge pressure sensors are a subset of piezoresistive transducers, which are a subset of pressure sensors, which fall under the sensor category in electronic measurement systems. The MPX series from NXP integrates the sensing element, signal conditioning, and calibration on a single silicon die. Key features include on-chip signal conditioning, factory calibration, and temperature compensation from 0 C to 85 C. The device operates from a single 4.75 V to 5.25 V supply and provides a ratiometric analog output proportional to applied pressure. The integrated port design accepts a 0.034 inch (0.86 mm) female tube connection for direct airflow or liquid coupling. The architecture uses a single-crystal silicon diaphragm with a diffused piezoresistive Wheatstone bridge. Laser-trimmed resistors and on-chip ASIC signal conditioning deliver a linear, amplified output that requires no external compensation components. The dual-vent port design provides stable operation in vented gauge applications where the reference side must be exposed to ambient pressure. Typical applications include HVAC airflow monitoring, medical respiratory equipment, variable air volume (VAV) controllers, industrial process control, and consumer appliance pressure feedback. The 3.92 kPa full-scale range is specifically optimized for low-pressure pneumatic and respiratory sensing where higher ranges would sacrifice resolution. When designing with this part, ensure the supply is regulated to within 5 percent and use ADC sampling at rates above 1 kHz to capture pressure transients. Decouple the supply pin with a 100 nF ceramic capacitor placed within 5 mm of the device. The sensor output is ratiometric to the supply - a 5.0 V supply produces a 1.0 V to 4.9 V output, while a 5.25 V supply scales proportionally.

MPXV5004GC6T1 - 3.92kPa Pressure Sensor, 5V, SOP-8 | NXP
The NXP MPXV5004GC6T1 is a piezoresistive, monolithic silicon pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, delivering an analog output voltage proportional to applied differential pressure over a 0 to 3.92 kPa (0 to 0.57 PSI) range from a single 5 V supply. The device is housed in an 8-pin SOP (Small Outline Package) with a top-side pressure port, gull-wing leads, and tape-and-reel packaging suitable for surface-mount assembly. A pressure sensor is a transducer that converts a physical pressure input into an electrical signal, typically an analog voltage proportional to the applied force per unit area. Piezoresistive sensors use diffused strain gauges on a silicon diaphragm whose resistance changes with deflection; the resulting signal is then conditioned, compensated for temperature, and calibrated on the wafer. Pressure sensors sit within the broader sensor hierarchy as MEMS devices, themselves a category of semiconductor components that interface physical phenomena to electronics. The MPXV5004 family is commonly used in respiratory, HVAC, and instrumentation applications where vented gauge measurement is required. Key features of the MPXV5004GC6T1 include a transfer function spanning 1.0 V at 0 kPa to 4.9 V at 3.92 kPa, a response time of approximately 1 ms, and an operating temperature range of 0°C to +85°C. The device incorporates a single-port vented gauge configuration with a 3.17 mm (0.13 inch) tube port on top, allowing direct connection to an airflow manifold. Output noise and accuracy are factory-calibrated, eliminating external compensation circuitry. Internally, the MPXV5004GC6T1 is fabricated using NXP's (formerly Motorola Semiconductor) micromachining and thin-film metallization process on a bipolar substrate, integrating the sensing diaphragm and CMOS-compatible signal conditioning on a single die. The vented gauge reference port on the underside of the die references the back side of the diaphragm to atmosphere, enabling fully compensated gauge readings. Typical applications include spirometers and CPAP airflow monitoring, HVAC variable air volume (VAV) controllers, industrial process instrumentation, pneumatic control feedback, and altitude/wind-pressure sensing in drone or weather stations. Its small SOP-8 footprint suits compact medical and consumer electronics. When designing with this part, ensure the supply is well decoupled near the VCC pin (typically 1 µF ceramic) and keep the pressure port free of moisture, debris, and condensation that can corrupt gauge readings. The output is ratiometric to VCC, so a stable, low-noise 5 V rail is essential for stated accuracy.

It measures vented gauge pressure from 0 to 3.92 kPa (0 to 0.57 psi, equivalent to 0 to ~400 mm H2O) and translates that pressure into a ratiometric analog output of 1.0 V to 4.9 V when supplied from a 5 V DC source. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a MEMS device in which implanted strain gauges on a silicon diaphragm change resistance proportionally to applied differential pressure. The MPXV5004 belongs to the monolithic silicon pressure sensor family, sitting in the hierarchy: MEMS pressure sensor -> piezoresistive transducer -> pressure sensor -> sensor IC -> semiconductor. It is designed to interface directly to an ADC input of a microcontroller or microprocessor without external signal conditioning. Key features include a 4.75 V to 5.25 V supply range, low pressure range (0 to 3.92 kPa) ideal for airflow and liquid-level sensing, ±2.5% accuracy (typical) over 10 °C to 50 °C, ratiometric analog output that compensates for supply variation, and on-chip temperature compensation from 10 °C to 60 °C. The 8-SMD gull-wing package is surface-mountable and includes an integrated port for direct pneumatic connection. Architecturally, the device combines a micromachined silicon diaphragm with thin-film metallization and bipolar signal-conditioning circuitry to produce a calibrated voltage output proportional to pressure. The piezoresistive bridge is laser-trimmed at wafer level for offset and span, eliminating the need for external passive trimming networks. The vented-gauge configuration references the low-side pressure to ambient via the package, simplifying hose routing in medical and HVAC applications. Typical applications include medical respiratory airflow monitoring (CPAP, ventilators, spirometers), HVAC variable-air-volume (VAV) controllers, industrial process control, low-differential gas flow metering, water-column level detection, and appliance pressure sensing. Its small size and analog output also make it well suited to portable battery-powered instruments where an MCU ADC is available. When designing with the MPXV5004GC6U, place 0.1 µF supply decoupling as close to VCC and GND pins as possible and route the analog output through a low-pass RC filter (typically 1 kΩ and 0.01 µF) to suppress high-frequency noise from the upstream switching converter. Account for the ratiometric output when designing the ADC reference: a stable 5 V supply is required for absolute accuracy; if the supply drifts, the output drifts proportionally.

MPXV5004GC7U - 0-3.92 kPa Vented Gauge Pressure Sensor | NXP
The NXP MPXV5004GC7U is an integrated silicon piezoresistive pressure sensor that measures vented gauge pressure from 0 kPa to 3.92 kPa (0 to 0.57 PSI) with on-chip signal conditioning, temperature compensation, and calibration. It produces an analog output from 1 V to 4.9 V at 5 V supply and is housed in an 8-pin DIP (0.550 inch / 13.97 mm) through-hole package with a top port tube inlet (0.13 inch / 3.17 mm). Originally developed by Motorola and transferred through Freescale to NXP, the part ships in a tube and targets applications where a small dead-volume, calibrated, ratiometric pressure-to-voltage transducer is needed. A pressure sensor is a transducer that converts an applied pressure into an electrical signal; a vented gauge sensor references its zero against an integrated vent port so it automatically compensates for atmospheric variation. The MPXV5004GC7U belongs to the MPxx5004 family of monolithic silicon sensors and sits within the broader hierarchy: pressure sensor -> pressure transducer -> sensor IC -> semiconductor. Piezoresistive strain gauges are implanted in a micromachined silicon diaphragm using thin-film metallization and bipolar processing, yielding an accurate analog output proportional to differential pressure. Key features of the MPXV5004GC7U include 0 to 3.92 kPa range with 1 V/kPa typical sensitivity, a ratiometric 5 V supply (4.75 V to 5.25 V), a top-port 3.17 mm tube inlet suited to small dead-volume plumbing, accuracy of approximately +/- 1.5 percent VFSS, on-chip temperature compensation from 0 C to 85 C, and a through-hole DIP footprint compatible with hand-soldered prototypes and leaded assembly lines. The vented gauge design means one side of the diaphragm is exposed to the application and the other side to ambient via the rear vent hole, simplifying system plumbing. From an architecture standpoint, the on-chip ASIC includes a Wheatstone-bridge piezoresistive network, a precision bandgap reference, a calibration trim network, and a buffered analog output stage. The device is intended for 5 V single-supply operation and produces a near-rail-to-rail output that interfaces directly to an external ADC, microcontroller ADC input, or comparator. The DIP-8 package isolates the front-side media port from the rear vent, which is required for proper gauge operation. Typical applications include CPAP / ventilator airflow monitoring, HVAC variable-air-volume box sensing, weather station barometric trending, respiratory spirometry, and portable medical / fitness airflow meters. In each case the small top port minimizes dead volume and the calibrated analog output eliminates the need for software scaling. When designing with this part, place the sensor close to the host ADC to minimize noise pickup, add a 100 nF decoupling capacitor near the supply pin, and avoid blocking the rear vent hole during PCB layout. The 8-pin DIP footprint is hand-solderable but the device is now primarily serviced through NXP legacy channels, so lead time and authorized stocking distributor verification should be checked at design-in.

The MPXV5004GVP is a vented gauge sensor, meaning it measures pressure relative to ambient atmospheric pressure through a vented reference side, making it ideal for applications where the surrounding barometric pressure is the natural zero reference. As a category, it sits within the hierarchy: pressure sensor -> sensor -> transducer -> electronic component, and is widely deployed in medical, HVAC, and consumer flow/level measurement. Key features include on-chip temperature compensation and calibration over 0°C to 85°C, ratiometric analog voltage output, monolithic silicon construction using advanced micromachining and thin-film metallization, and a robust 8-SMD module with vertical port for easy tube/fitting attachment.

The differential pneumatic lines should be sized to minimize windage errors at the intended flow bandwidth, and the dual-port configuration requires careful port-plumbing orientation to avoid cross-port pressure leakage. This page consolidates verified distributor pricing, drop-in alternatives and practical design considerations for the MPXV5010DP that go beyond the manufacturer datasheet alone.
MPXV5010G6U - 10 kPa Vented Gauge Pressure Sensor | NXP
The NXP MPXV5010G6U is an integrated, on-chip signal-conditioned silicon piezoresistive pressure sensor housed in an 8-SMD (SO gull-wing) module. It measures a vented gauge pressure range of 0 kPa to 10 kPa (0 to 1.45 PSI) and provides a ratiometric analog output of 0.2 V to 4.7 V from a single 5 V supply. The sensor is factory calibrated and temperature compensated across 0 °C to 85 °C. A piezoresistive pressure sensor is a MEMS device in which a micromachined silicon diaphragm flexes under applied pressure, changing the resistance of embedded strain gauges arranged in a Wheatstone bridge. The on-chip ASIC then amplifies, calibrates, and temperature-compensates the bridge output to deliver a near-linear voltage proportional to pressure. These devices sit in a measurement hierarchy of absolute, gauge, differential, and vented-gauge types and are widely used where a microcontroller or ADC can read the analog output directly. Key features include a 5 % maximum pressure error (over 0–80 °C), a typical response time of 1 ms, and a 10 kPa full-scale range that resolves about 2.3 mV per Pa through the 0.2 V–4.7 V output swing.

The compact 8-SMD footprint supports space-constrained designs such as handheld patient monitors and IoT environmental nodes. When designing in, place 100 nF and 470 pF supply decoupling close to the Vs and GND pins, and follow the manufacturer reference PCB layout to minimize stress on the silicon die. Ratiometric operation requires the ADC reference to share the same 5 V rail as the sensor for specified accuracy.

MPXV5010GC6T1 - 10 kPa Vented Gauge Pressure Sensor | NXP
The NXP MPXV5010GC6T1 is a monolithic piezoresistive silicon pressure sensor that delivers an amplified, temperature-compensated analog output proportional to applied pressure. It measures 0 kPa to 10 kPa (1.45 PSI) in vented gauge mode and produces a 0.2 V to 4.7 V ratiometric analog output from a 5 V supply. The device is packaged in an 8-pin SO (Small Outline) SMD module with a top-port male 0.13" (3.17 mm) tube inlet and gull-wing leads for surface-mount assembly. A piezoresistive pressure sensor is a MEMS device in which diffused silicon strain gauges arranged in a Wheatstone bridge change resistance when a diaphragm is deflected by differential pressure; in a vented-gauge sensor the back side of the diaphragm is referenced to ambient through a vent hole so the output is a true gauge measurement. The MPXV5010GC6T1 sits in the category hierarchy pressure sensor -> MEMS sensor -> sensor IC, and is widely used as the analog front-end between a physical pressure port and a microcontroller ADC. The key features include (i) on-chip signal conditioning and calibration, (ii) temperature compensation over 0 C to +85 C, (iii) ratiometric 5 V supply operation, (iv) 1.0 % typical linearity over the full 0 to 10 kPa range, and (v) a top-port pressure inlet compatible with flexible tubing. The on-chip ASIC amplifies the bridge signal to a near-rail-to-rail swing, eliminating the external instrumentation amplifier that raw bridge sensors normally require. Technically, the device uses bipolar signal-conditioning circuitry with thin-film metallized resistors laser-trimmed at the wafer level to provide gain and offset calibration; the ratiometric output (5 % to 94 % of VCC) ensures that the reading scales with the ADC reference for inherent supply-noise rejection. The vent path routes ambient pressure to the back side of the diaphragm so altitude or weather changes do not bias the measurement. Typical applications include medical spirometry and respiratory monitoring, HVAC air-flow sensing, gas-flow instrumentation, industrial pressure switches, and altitude-compensated barometric sensing. Designers use the 0.2 V idle (zero pressure) offset and the 4.5 V full-scale span to compute pressure as V / 0.45 - 0.444 kPa when VCC = 5 V. When designing with this part, place a 0.01 uF CPL bypass capacitor close to VCC and route the vent port away from pump-induced pressure gradients. For many LED/MPX use cases, field-folding the vents into this field is not needed - external venting does not pass through this field, so PCB layout can be compact and routed away from heat sources.

The integrated design eliminates external compensation components, simplifying BOM and PCB area. Architecturally the device uses a diffused piezoresistive bridge on a micromachined silicon diaphragm; the bridge is excited by the supply and the differential output is amplified and offset by on-chip bipolar circuitry to produce a near-ground-referenced, rail-ratiometric transfer function. This architecture delivers factory-calibrated accuracy over the specified pressure range without user trimming. Typical applications include medical respiratory monitoring (spirometers, ventilators), HVAC variable-air-volume (VAV) controls, gas flow sensing, industrial process monitoring, and consumer airflow measurement. The wide 0 to 10 kPa range with 1.45 PSI full-scale suits both human-breath pressure monitoring and low-pressure industrial gas lines. When designing with this part, observe the 4.75 V to 5.25 V supply window to preserve ratiometric output accuracy, place a 100 nF decoupling capacitor close to the supply pin, and account for the vented-gauge reference in altitude-sensitive applications. The tube inlet orientation (top port) constrains PCB placement relative to the air path.

It operates from a single 5 V supply, provides a typical full-scale output of 4.5 V at 10 kPa, and incorporates a patented dual-port axial horizontal pressure inlet geometry that simplifies pneumatic connection in space-constrained enclosures. A piezoresistive differential pressure sensor is a transducer that converts a mechanical pressure differential into a proportional electrical signal using micromachined silicon strain gauges arranged in a Wheatstone bridge; the MPXV5010 family belongs to the wider pressure-sensor hierarchy (pressure sensor -> transducer -> sensor IC -> analog front-end -> signal conditioning chain) used wherever a microcontroller or microprocessor with an A/D input must read differential, gauge, or absolute pressure. The MPXV5010GC7U is the gauge-version "G" of the MPX5010 family, meaning it measures pressure referenced to atmospheric ambient rather than a sealed vacuum reference. Key differentiating features include on-chip temperature compensation from 0 °C to 85 °C, laser-trimmed calibration for span and offset, an internal EMI/RFI protection network, and typical pressure resolution equivalent to the A/D converter used downstream. The device provides an output impedance below 50 ohm suitable for direct connection to most microcontroller A/D inputs, and a startup time of approximately 20 ms after VCC valid. The die is protected against humidity and contamination by a silicone gel coating. The transducer combines advanced micromachining, thin-film metallization, and bipolar signal processing to provide a high-level linear analog output, eliminating the need for external active circuitry in many applications. The architecture's main electrical trade-off is high quiescent current relative to a bare bridge, accepted in exchange for a calibrated, ratiometric, output-scaled signal. Typical applications include HVAC variable-air-volume (VAV) control, medical respirators and ventilators, process control manifolds, level detection in non-corrosive liquids, appliance pressure monitoring, and automotive manifold pressure sensing. It also serves as a low-cost drop-in for similar gauge-pressure sensing in industrial pumps. Designers should degauss or, more practically, isolate the sensor inlet tubing to prevent condensation ingress, place a 0.1 µF decoupling capacitor adjacent to VCC and GND, and account for the 1 % typical accuracy combined with thermal warm-up drift in long-time-constant applications.

MPXV5010GP - 0-10 kPa Vented Gauge Pressure Sensor, 8-SMD | STMicroelectronics
The STMicroelectronics MPXV5010GP is an integrated silicon piezoresistive pressure transducer delivering precise 0 to 10 kPa (0 to 1.45 PSI) vented gauge pressure measurements with an analog output swing of 0.2 V to 4.7 V from a single 5 V supply. Housed in an 8-SMD gull-wing, side-port package, this on-chip signal-conditioned, temperature-compensated and factory-calibrated sensor targets embedded designs that require a clean, linear analog voltage proportional to applied pressure. A pressure sensor (or pressure transducer) is a MEMS device that converts an applied differential or gauge pressure into a measurable electrical signal. The MPXV5010GP sits within the broader hierarchy of MEMS sensors -> sensors -> semiconductors, and specifically belongs to the piezoresistive transducer family, which uses a silicon diaphragm whose resistance changes under strain. Its on-chip ASIC conditions, compensates and calibrates the raw bridge output, removing the need for external linearization and temperature correction in most applications. Key features include a maximum pressure range of 10 kPa, a full-scale output of 4.7 V typical, a sensitivity of approximately 450 mV per kPa, and an integrated temperature compensation network covering 0 to 85 C. The single 5 V supply requirement, low 5 mA typical current consumption, and ratiometric analog output simplify integration with any MCU or MPU that exposes an A/D input. The side-port tube inlet accepts 3.17 mm (0.13 in) tubing and the vented gauge reference makes the sensor suitable for applications that must reject atmospheric pressure changes. Architecturally, the part combines a micromachined silicon diaphragm with thin-film metallization and a bipolar signal-conditioning ASIC on the same die, achieving high accuracy across the calibrated range. The MPxx5010 series is engineered specifically for microcontroller- or microprocessor-based systems with A/D inputs, and the analog voltage swing is sized to directly drive a 5 V ADC reference rail. Calibration coefficients are trimmed at the factory, eliminating user-side compensation in most designs. Typical applications include medical respiratory monitoring and ventilators, HVAC variable-air-volume (VAV) controllers, respiratory spirometers, altimeters and barometers, industrial process monitoring, and consumer weather stations. The wide 0 to 10 kPa range corresponds to 0 to ~75 cm H2O, making it well-matched to human breath-pressure measurement. When designing with this device, route the side-port inlet away from PCB mounting stress and provide adequate clearance around the pressure port. Use a stable 5 V supply for best accuracy because the output is ratiometric; any supply ripple will appear as a pressure reading error. Place 100 nF decoupling close to VDD and add a small RC filter at the output if ADC inputs are sensitive to switching noise.
MPXV5050DP - 50 kPa Differential Pressure Sensor | NXP Semiconductors
The NXP Semiconductors MPXV5050DP is a monolithic, signal-conditioned, temperature-compensated and calibrated differential piezoresistive silicon pressure sensor with a 0 to 50 kPa (0 to 7.25 psi) full-scale range, dual axial ports on the same side, and an analog ratiometric output from 0.2 V to 4.7 V at 5 V supply, housed in an 8-pin SO package (SOT1693-1, 12.06 mm x 12.06 mm). It is a surface-mount variant of the legacy Motorola MPX5050 family and integrates on-chip bipolar op-amp circuitry plus thin-film resistor networks so that the output is linear, calibrated, and ready to feed directly into an MCU ADC without external compensation. A pressure sensor is a transducer that converts an applied pneumatic or hydraulic pressure into a proportional electrical signal; differential variants like the MPXV5050DP measure the difference between two applied pressures through two ports, while gauge variants measure against atmosphere. Piezoresistive silicon sensors dominate low-pressure applications because the Wheatstone bridge of strain-sensitive diffused resistors changes resistance proportionally to membrane deflection, and on-chip CMOS/bipolar signal conditioning converts that small bridge delta into a high-level, ground-referenced voltage that downstream microcontrollers can sample. Within the broader sensor taxonomy, the MPXV5050DP belongs to MEMS pressure sensors, a sub-class of motion/force sensors used wherever clean, conditioned pressure data is needed. Key features include: 0 to 50 kPa operating range, 5 V typical supply (max 6.0 V), ratiometric analog output nominally Vout = 5 V x (0.009 x P(kPa) - 0.045) over the 0 to 50 kPa span, on-chip temperature compensation over 0 C to +85 C, differential dual-port configuration on the same side, low standby current, and AEC-Q100 qualification for automotive use. The integrated bipolar op-amp front end and thin-film trim network provide a factory-trimmed offset and span, eliminating the manual calibration that discrete bridge sensors require. Technically, the part uses a single-element monolithic diaphragm with a diffused piezoresistive bridge, advanced micromachining, thin-film metallization, and bipolar signal processing. Because the output is ratiometric with Vdd, ADC readings stay accurate even if the 5 V rail drifts, provided the MCU's ADC reference is also tied to the same 5 V supply. The dual-port differential topology allows measurement across an orifice, filter, or HVAC duct without exposing the sensor to ambient humidity contamination. Typical applications include medical respiration/airflow monitoring, HVAC variable-air-volume (VAV) controllers, industrial process control, appliance pressure feedback (e.g., washing-machine water level), and automotive manifold absolute/differential sensing. The differential configuration makes it ideal for flow-via-orifice measurement, where a known restriction generates a measurable pressure drop. When designing with this part, place 100 nF decoupling close to Vdd, keep port tubing short and rigid to dampen vibration, and use the same 5 V rail as the ADC reference for best accuracy. Avoid exposing the ports to condensing moisture or corrosive media; the device is specified for clean, dry, non-corrosive gases only.

MPXV5050GP - 0-50 kPa Vented Gauge Pressure Sensor | NXP / ST
The NXP MPXV5050GP is a state-of-the-art monolithic silicon piezoresistive pressure sensor with on-chip bipolar op-amp signal conditioning, thin-film temperature compensation, and factory calibration. It measures vented gauge pressure from 0 to 50 kPa (0 to 7.25 PSI) and provides an analog ratiometric output of approximately 0.2 V to 4.7 V from a 5 V supply, housed in an 8-pin SO SMD (SOT1693-1) gull-wing package with a vertical side port. An integrated silicon pressure sensor is a MEMS device that converts applied differential or gauge pressure into a calibrated analog voltage, combining the mechanical diaphragm, Wheatstone-bridge piezoresistors, amplifier, and compensation network on a single die. Within the broader taxonomy it sits under sensors -> pressure -> microphone, while electrically behaving like a ratiometric analog sensor front-end that downstream ADCs or microcontrollers can sample directly. Key features include 5 V typical supply, 0.2 V to 4.7 V ratiometric output span, integrated temperature compensation from 0C to +85C, and a typical full-scale span of 4.5 V. The on-chip bipolar op-amp and laser-trimmed thin-film network remove the need for external analog compensation, allowing designers to drop the sensor into a microcontroller ADC channel with only decoupling capacitors. Small form factor (12.06 mm x 12.06 mm x 3.38 mm body) and 2.54 mm pitch make it well suited to high-volume SMT lines. Architecture combines a micromachined silicon diaphragm with diffused piezoresistors in a Wheatstone bridge, followed by a bipolar op-amp stage that converts bridge imbalance to a ground-referenced, supply-ratiometric output. The on-chip thin-film network calibrates offset and span across temperature, giving repeatable readings without external trimming. Typical applications include medical respiratory monitoring, HVAC air-flow sensing, industrial process control, altimeter/barometric modules, and appliance water-level / pressure feedback. Designers should run the sensor from a low-noise 5 V rail because PSRR is limited by the front-end topology, and add a small RC filter on the output when long analog traces pick up noise.
MPXV5050VC6T1 - 50 kPa Vacuum Pressure Sensor, 5V, SOP-8
The STMicroelectronics (formerly NXP/Freescale) MPXV5050VC6T1 is a monolithic, signal-conditioned, silicon piezoresistive pressure sensor in an 8-SMD gull-wing (SOP-8, case 1737-02) package with a top-side vertical tube port. It measures vacuum and gauge pressure from 0 to -50 kPa (-7.25 PSI) and produces a ratiometric analog output of 0.1 V to 4.6 V from a single 5 V supply, calibrated directly by on-chip bipolar op-amp and thin-film resistor networks. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a MEMS device in which four silicon piezoresistors arranged in a Wheatstone bridge on a diaphragm change resistance in proportion to applied strain. As pressure deflects the diaphragm, the bridge output is amplified and conditioned by on-chip circuitry to deliver a high-level, temperature-compensated analog voltage proportional to pressure, eliminating the external instrumentation amplifier and calibration steps normally required for bare bridge sensors. The MPXV5050VC6T1 family is rated for a pressure range of 0 to -50 kPa (vacuum mode) with a sensitivity of 90 mV/kPa and a 5 V supply span. The integrated signal chain delivers 5% accuracy over 0°C to 85°C, on-chip temperature compensation, and a typical response time suitable for industrial, medical, and HVAC closed-loop control. The SOP-8 surface-mount form factor with top port and 0.13 inch (3.17 mm) tube port allows direct manifold mounting and high-volume pick-and-place assembly. Typical applications include vacuum pump monitoring, HVAC airflow sensing, respirator and ventilator pressure feedback, barometric altitude estimation, and industrial process control where a conditioned 0.1 V to 4.6 V analog output can be read directly by an MCU ADC. When designing with this part, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin, and add a 1 µF bulk capacitor on the supply rail. Drive the analog output through an RC low-pass filter if the application samples at less than the sensor's response bandwidth to avoid aliasing.

MPXV5100DP - 100kPa Differential Pressure Sensor, 5V, 8-SOP | NXP
The NXP MPXV5100DP is a monolithic silicon piezoresistive differential pressure sensor with on-chip signal conditioning, measuring 0 to 100 kPa (0 to 14.5 PSI) and outputting an amplified 0.2 V to 4.7 V analog ratiometric signal from a 5 V supply in an 8-BSOP (SO-8 dual-port) surface-mount package. A piezoresistive pressure sensor is a device that converts applied mechanical pressure into a proportional change in electrical resistance, which is then linearized and amplified by on-chip circuitry into an analog output voltage directly readable by an MCU ADC. In the broader sensor taxonomy, this part is a board-mount pressure transducer -> MEMS sensor -> pressure sensor -> physical sensor. The MPXV5100DP integrates the mechanical diaphragm, Wheatstone bridge, temperature compensation, gain stage, and calibration on a single die, eliminating the need for external compensation networks. Key features include 5% maximum pressure accuracy (typically better over 0 to 85 C), 45 mV/kPa nominal output span, Ratiometric analog output proportional to supply voltage, dual horizontal ports for differential sensing, and on-chip temperature compensation. The dual-port package allows easy pneumatic connection with flexible tubing on both sides of the sensor die. The device uses advanced thin-film metallization and bipolar semiconductor processing to combine a single-element piezoresistive transducer with bipolar signal conditioning. The ratiometric output architecture means the output scales linearly with VCC, enabling direct ADC readings without precision reference voltage requirements. Typical applications include HVAC airflow and differential pressure monitoring, medical respiratory equipment, process control and pump monitoring, altitude and barometric estimation, and industrial pneumatic feedback. The dual-port configuration makes it especially well suited to measuring pressure drop across filters, ducts, orifices, and flow elements. When designing with this sensor, ensure the supply is well-decoupled with a 0.1 uF ceramic capacitor placed close to VCC and GND. Avoid exposing the ports to moisture, dust, or corrosive gases; the device is specified for clean dry air or non-corrosive gases only. This page consolidates distributor pricing, drop-in same-package alternatives, and engineering design notes not collected in the manufacturer datasheet, supporting faster cross-reference decisions for engineers who already know the MPXV5100DP from prior designs.
MPXV5100GC6U - 100kPa Vented Gauge Pressure Sensor | NXP
The NXP MPXV5100GC6U is a piezoresistive monolithic silicon pressure sensor that delivers a calibrated, temperature-compensated analog output of 0.2 V to 4.7 V for a pressure range of 0 kPa to 100 kPa (0 PSI to 14.5 PSI) in a vented gauge configuration. The transducer integrates on-chip signal conditioning, ASIC-style temperature compensation, and a precision thin-film resistor network to produce a near-linear ratiometric output that interfaces directly with a microcontroller A/D input. It is housed in an 8-pin SMD gull-wing SOP package with a top-side port that accepts a 0.13" (3.17 mm) tube, allowing pneumatic connection from the top of the device. A piezoresistive pressure sensor is a micro-electromechanical (MEMS) device in which diffused strain gauges on a silicon diaphragm change resistance proportionally to applied differential pressure; the sensor IC then conditions this Wheatstone-bridge signal into a usable voltage output. This category belongs to the broader hierarchy of MEMS sensors -> pressure transducers -> environmental/physical sensors -> semiconductor components, where it sits alongside load cells, capacitive pressure sensors, and force-sensitive resistors as one of several transducer families. The MPXV5100GC6U belongs to the MPX5100/MPXV5100 series, which is the most widely adopted high-pressure (>50 kPa) variant of this NXP family. Key differentiating features include the 0.2 V to 4.7 V ratiometric output (5 V supply → 4.7 V full-scale span), an accuracy of approximately 2.5 % of full-scale span, a fast response time of 1.0 ms, and a single 5 V supply operation. The vented gauge reference eliminates the need for external barometric compensation in many indoor applications, and the integrated temperature compensation between 0 °C and 85 °C removes the burden of software-based correction. The SOP-8 top-port package is optimized for tube-fed pneumatic systems and is compatible with standard 3.17 mm pneumatic tubing. Internally, the device combines bipolar signal-conditioning ASICs, thin-film metallization for bridge resistors, and bipolar processing for the active silicon diaphragm. This hybrid integration provides factory-calibrated output without the user needing to perform multi-point calibration in firmware, although system-level gain/offset trimming remains advisable for the most demanding instrumentation applications. Typical applications include HVAC air-flow monitoring, industrial process control, altimeters and barometric measurement, medical respiratory equipment, electronic scales and load-cell augmentation, and engine manifold absolute pressure (MAP) sensing when externally referenced. The 100 kPa range covers most non-absolute-pressure scenarios in industrial and consumer instrumentation. When designing with this part, choose a low-impedance ADC input or add a unity-gain buffer between the sensor output and the MCU; the output cannot drive high-current loads directly. Decouple the VCC pin with a 0.1 µF ceramic capacitor placed within 5 mm of the package lead, and avoid sharp tube bends that introduce flow-induced noise. For barometric applications above 100 kPa, consider the MPXV5100DP (differential) variant.

MPXV5100GC7U - 100kPa Gauge Pressure Sensor, 5V | STMicroelectronics
The STMicroelectronics MPXV5100GC7U is an integrated piezoresistive pressure transducer that delivers a calibrated, temperature-compensated analog output for gauge pressures from 0 to 100 kPa (0 to 14.5 PSI). It operates from a single 5 V supply, provides a 0.2 V to 4.7 V ratiometric output across its pressure range, and is housed in an 8-DIP package (0.550" body, 13.97 mm) with a top-mounted 0.13" (3.17 mm) tube port for ease of pneumatic connection. A piezoresistive pressure sensor is a solid-state transducer in which strain gauges diffused into a silicon diaphragm change resistance in proportion to applied pressure; the die integrates the sensor, signal conditioning, and calibration in a single monolithic silicon substrate. In the broader sensor taxonomy, the MPXV5100GC7U belongs to the MEMS pressure sensor family, which sits under semiconductor sensors and within signal-conditioning sensor modules used by microcontrollers with analog-to-digital inputs. Key specifications include a maximum pressure rating of 400 kPa, a sensitivity of 45 mV/kPa, an accuracy of 1.5% over 0 to 85 °C, and a response time of 1.0 ms. The package offers a vented-gauge reference through the side port, allowing absolute atmospheric reference for differential measurements in real-world installations. The architecture combines advanced micromachining, thin-film metallization, and bipolar signal processing to deliver a linear analog output. The internal ASIC performs offset calibration, span calibration, and temperature compensation at the wafer level, removing the need for external user trimming in most applications while keeping the pin count and BOM low. Typical applications include medical patient monitoring (respiratory and blood pressure instrumentation), industrial process controls, pump and motor pressure feedback, HVAC pressure switching, and weather station barometric measurement. The vented-gauge configuration also makes the part well suited to altitude and small-differential measurements where atmospheric reference is required. When designing with the MPXV5100GC7U, pay attention to input supply decoupling (a 100 nF plus 10 µF combination is recommended near VCC), the orientation of the vent port relative to the application environment, and the proper sizing of the analog input bandwidth on the host ADC to avoid aliasing the 1 ms response. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet's typical application section to help engineers shorten the design cycle.
MPXV53GC7U - 50 kPa Uncompensated Vented Gauge Pressure Sensor | NXP
The NXP (formerly Freescale/Motorola) MPXV53GC7U is a 50 kPa (7.25 PSI) uncompensated, vented-gauge silicon piezoresistive pressure sensor housed in an 8-pin DIP through-hole package with a top-mounted 0.13" (3.17 mm) tube port. It produces an analog differential voltage output of 0 mV to 60 mV at 3 V excitation that is directly proportional to applied pressure, and its vented-gauge reference allows barometric pressure compensation via the side vent hole. A piezoresistive pressure sensor is a MEMS device in which four strain-sensitive resistors arranged in a Wheatstone bridge on a silicon diaphragm change resistance when pressure deflects the diaphragm. The bridge is excited by an external voltage (typically 3 V to 10 V) and delivers a low-level analog output that the user conditions with op-amps, instrumentation amplifiers, or dedicated ADC front-ends. In the broader hierarchy, the MPXV53GC7U sits in the transducer sub-family of sensors, which falls under MEMS sensors, semiconductor sensors, and finally signal-chain components. Key specifications include a 0 kPa to 50 kPa operating range, 60 mV full-scale output at 3 V excitation, 1.0 mV/kPa typical sensitivity, a 1.0 kΩ to 3.0 kΩ input impedance, and a -40 °C to +125 °C operating temperature range. The package is through-hole DIP-8 (0.550" / 13.97 mm body width) with port style A (top port), and the uncompensated nature means offset, span, and nonlinearity calibration are performed by the host circuit. The sensing element is a monolithic silicon diaphragm with an implanted piezoresistive bridge, laser-trimmed for span but deliberately left without temperature or offset compensation. This makes the device well-suited to cost-sensitive applications where the downstream MCU or analog signal chain can perform software compensation. Because the device is uncompensated, PCB designers must keep excitation and reference paths short to minimize noise pickup and thermal EMF. Typical applications include medical respiratory monitoring (spirometers, ventilators, CPAP), HVAC variable-air-volume (VAV) controllers, altimeters and barometric correction, air-flow and draft sensing, process control gauges, and hobby/drone altitude estimation. The vented-gauge topology inherently compensates for changes in ambient barometric pressure, which simplifies outdoor installations. When designing with this sensor, pair it with a low-noise instrumentation amplifier such as an INA125 or a 24-bit delta-sigma ADC such as the ADS1220 to digitize the millivolt-level output. Provide a clean, low-noise 3 V to 5 V excitation supply; any ripple on the excitation appears directly in the output. Avoid placing the part near heat sources because uncompensated sensors exhibit thermal drift that cannot be corrected without calibration data.
MPXV6115V6T1 - -115kPa Vacuum Pressure Sensor, 5V, SOP-8 | NXP
The NXP MPXV6115V6T1 is a monolithic, signal-conditioned silicon pressure sensor that measures vacuum (negative gauge) pressure from 0 kPa down to -115 kPa (-16.68 PSI), packaged in a small-outline 8-SMD gull-wing SOP-8 module. The device integrates on-chip bipolar op-amp circuitry and thin-film resistor networks to provide a temperature-compensated, high-level analog output of 0.2 V to 4.6 V from a single 5 V supply (4.75 V to 5.25 V), with a typical accuracy of ±1.5%. What is a board-mount pressure sensor? A board-mount pressure sensor is a MEMS-based transducer that converts applied pneumatic pressure into a calibrated analog voltage and is soldered directly onto a PCB, eliminating hose-to-PCB connectors. Within the broader sensor hierarchy, it belongs to piezoresistive MEMS sensors -> pressure sensors -> transducers -> sensors -> electronic components. The MPXV6115V6T1 is part of NXP's integrated MPXx family that adds ASIC signal conditioning directly on the silicon die, simplifying downstream analog front-end design. Key features include a calibrated full-scale output span of approximately 4.4 V across the -115 kPa to 0 kPa vacuum range, an on-chip temperature compensation network that flattens the output across 0 C to +85 C, and a robust gull-wing SMD leadframe that survives standard reflow profiles. The single-rail 5 V supply and ratiometric analog output simplify interfacing to microcontrollers with built-in ADCs, while the integrated op-amp eliminates the need for an external instrumentation amplifier. Architecturally, the MPXV6115V6T1 uses a piezoresistive Wheatstone bridge diffused into a micromachined silicon diaphragm; the bridge output is conditioned by an on-die bipolar op-amp stage and a thin-film resistor network that performs offset and span calibration plus first-order temperature compensation. This integration trades the noise and drift of a discrete instrumentation chain for the convenience of a calibrated, ready-to-use analog module. Typical applications include HVAC vacuum monitoring, medical respiratory equipment, barometric altitude correction, and industrial process control where a compact, surface-mount vacuum transducer is required. The wide 0.2 V to 4.6 V swing is particularly well-suited to 5 V ADC full-scale ranges without external signal conditioning. When designing with this part, place 100 nF decoupling close to the supply pin and route the analog output away from switching nodes. The sensor is ratiometric to VDD, so any ripple on the 5 V rail appears directly on the output; an LDO upstream improves absolute accuracy. This page synthesizes distributor pricing, same-package drop-in alternatives within the MPXx family, and practical PCB layout notes not found in the manufacturer datasheet alone.
MPXV6115VC6U - -115kPa Vacuum Pressure Sensor | NXP | 8-SMD
The NXP MPXV6115VC6U is a single-port, vacuum-gauge integrated silicon pressure sensor that measures pressures from -16.68 PSI (-115 kPa) up to 0 PSI (0 kPa) and provides a ratiometric analog output of 0.2 V to 4.6 V from a 5 V supply. Housed in an 8-SMD, gull-wing, top-port surface-mount module, the device integrates on-chip bipolar op-amp signal conditioning, a thin-film resistor network for calibration, and temperature compensation to deliver a high-level, factory-trimmed output. A pressure sensor transducer is a semiconductor device that converts an applied pressure - mechanical force per unit area - into a proportional electrical signal, typically via a piezoresistive strain-gauge network diffused into a silicon diaphragm. The MPXV6115VC6U belongs to the broader piezoresistive transducer family (piezoresistive sensor -> pressure sensor -> MEMS sensor -> transducer) and is widely used in system-level designs where a clean, conditioned analog rail directly interfaces with a microcontroller ADC. Key features include a measurement range of -16.68 PSI to 0 PSI (-115 kPa to 0 kPa), a ratiometric 0.2 V to 4.6 V output, a typical accuracy of 1.5% across the compensated temperature range, and a 5 V single-supply operation. The 3.17 mm (0.13 in) vertical top port accepts a vacuum tube directly, eliminating hose-to-board adapters in many respiratory and analytical instrument designs. The MPXV6115VC6U uses a piezoresistive Wheatstone-bridge strain-gauge network diffused into a chemically-etched silicon diaphragm; deflection under vacuum unbalances the bridge, and the on-chip bipolar op-amp network amplifies and temperature-trims the differential signal to a single-ended 0.2 V to 4.6 V output. The 8-SMD gull-wing package is a surface-mount variant of the legacy SOP-8 with extended leads for improved solder-joint reliability, and the device is qualified for -40 C to +125 C operation. Typical applications include medical respiratory and CPAP instruments, HVAC vacuum monitoring, industrial vacuum gauges, and analytical instruments such as COVID-19 diagnostic consumables. The vacuum-only range and ratiometric output make the part particularly well suited to single-supply battery-powered systems that need a calibrated, temperature-compensated vacuum reading without external signal conditioning. When designing with this device, route the analog output trace away from switching converters and add an RC filter at the ADC input; the small output swing (0.2 V to 4.6 V) sits well within the common-mode range of most 5 V SAR ADCs but is sensitive to ground noise. The top port must remain unobstructed for accurate readings.
MPXV7002DP - ±2kPa Differential Pressure Sensor | NXP | 8-BSOP
The NXP Semiconductors MPXV7002DP is a monolithic silicon piezoresistive differential pressure sensor with a range of ±2 kPa (±0.29 PSI), housed in an 8-BSOP package with dual horizontal ports on the same side. It is designed for applications employing a microcontroller or microprocessor with A/D inputs, combining advanced micromachining, thin-film metallization, and bipolar semiconductor processing to provide a calibrated, temperature-compensated analog output. A differential pressure sensor is a transducer that converts a pressure difference between two ports into a proportional analog voltage, enabling measurement of flow, level, altitude, or velocity. In the broader sensor taxonomy, the MPXV7002DP sits under: pressure sensor -> MEMS sensor -> piezoresistive transducer -> sensor IC. Differential variants contrast with gauge sensors (which measure against atmosphere) and absolute sensors (which measure against vacuum). The MPXV7002DP's small differential range and integrated signal conditioning make it ideal for low-pressure fluid and air systems. Key specifications include a typical full-scale output span of 0.5 V to 4.5 V at 5 V supply (5% transfer function), 1.0 ms response time, temperature compensation across 0C to 85C, and on-chip signal conditioning. The output is ratiometric to supply voltage, allowing direct interface with 5 V ADCs without precision references. The dual-port same-side configuration supports clean pneumatic plumbing with standard 3.3 mm tubes. Architecture-wise, the sensor uses four piezoresistors in a Wheatstone bridge micromachined into the silicon die; deformation of the diaphragm under differential pressure unbalances the bridge, producing a differential voltage proportional to applied pressure. On-chip CMOS circuitry amplifies, temperature-compensates, and calibrates this signal, delivering a buffered output of approximately 1 V at -2 kPa and 4 V at +2 kPa with 5 V excitation. Typical applications include HVAC variable-air-volume (VAV) control, drone/UAV pitot-tube airspeed measurement, medical respiratory flow monitoring, and industrial process flow sensing. In each case the differential topology enables bidirectional flow measurement across fans, blowers, orifices, and pitot probes. A key design consideration is pneumatic port orientation and moisture protection. Because the dual ports are side-by-side and share the package edge, condensation or contamination can affect accuracy. Many designers add sintered bronze filters or hydrophobic membranes at the tubing interface for robustness. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers evaluate the MPXV7002DP against modern alternatives.
MPXV7007DP - ±7kPa Differential Pressure Sensor | NXP | SOP-8
The NXP MPXV7007DP is a monolithic silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, measuring differential pressure over a ±7 kPa (±1.02 psi) range from a single 5 V supply. Housed in an 8-BSOP (Small Outline Package) with dual side-by-side pressure ports, it provides a ratiometric analog output of 0.5 V to 4.5 V centered at 2.5 V. A piezoresistive pressure sensor is a MEMS device in which implanted resistors change resistance when deflected by applied pressure, producing a millivolt-level signal that is amplified and offset within the same silicon die. Compared to other transducer families, integrated pressure sensors such as the MPXV7007DP remove the need for external amplification, trimming, and thermal compensation networks, simplifying microcontroller- and microprocessor-based data acquisition. Key specifications include a 5 V typical supply (4.75 V to 5.25 V), 7 kPa full-scale span in both positive and negative pressure directions, 5% accuracy over 0 °C to 85 °C, and 1 ms response time suitable for real-time flow and blockage detection. The dual-port top-side port geometry is convenient for hose or tube mounting. The transducer employs bipolar signal conditioning combined with thin-film metallization and laser-trimmed calibration, allowing direct ADC input on most microcontrollers. The ratiometric output scales with supply voltage, preserving accuracy when powered from unregulated rails. Internal EMI/RFI filtering and reverse-supply protection improve robustness in industrial and appliance environments. Typical applications include HVAC damper feedback, respiratory/CPAP airflow monitoring, liquid level detection in sealed containers, washing-machine water-level sensing, and industrial process control loops. Designers also use it in tire-pressure monitoring prototypes and altitude simulators for UAVs. When integrating the MPXV7007DP, mount the part with port fittings oriented away from vibration sources and add a 0.1 µF decoupling capacitor adjacent to the supply pin. For differential measurements, route both ports through identical tubing to minimize common-mode error caused by wind or acceleration. This page consolidates distributor stock, parametric alternatives, and application guidance not found on any single manufacturer page.
MPXV7007GC6U - ±7kPa Compound Pressure Sensor 5V SOP-8 | NXP
The NXP MPXV7007GC6U is an integrated silicon piezoresistive pressure transducer that provides a calibrated, temperature-compensated analog output proportional to applied pressure. It measures compound pressure from -7 kPa to +7 kPa (about -1.02 to +1.02 PSI), operates from a single 5 V supply, and delivers a ratiometric analog output of 0.5 V to 4.5 V. The device is housed in a Small Outline Package (SOP-8, surface-mount, top port) measuring 11.4 x 8.1 x 6.4 mm with an integrated axial pressure port that accepts 3.17 mm (1/8 in) tubing. A pressure sensor (also called a pressure transducer) is a device that converts an applied pneumatic or hydraulic pressure into a measurable electrical signal. Within the sensor taxonomy, the MPXV7007GC6U belongs to the MEMS piezoresistive family, where silicon strain gauges diffused into a diaphragm change resistance as the diaphragm flexes under pressure. These gauges are typically Wheatstone-bridge configured on-chip, with integrated signal conditioning (amplification, offset, and temperature compensation) so that the output is linear, calibrated, and ready to be read by a microcontroller ADC. Key specifications include a pressure range of ±7 kPa with full-scale span of 4.0 V (typical), an operating temperature range of -40 °C to +125 °C, an accuracy of ±1.5 %VFSS (max) over the compensated range of 0 °C to +85 °C, a supply current of typically 7 mA, and ESD protection of 2 kV HBM on the pressure port and 200 V on the signal pins. The device uses on-chip temperature compensation and calibration, eliminating external trimming in production. The SOP-8 surface-mount package simplifies PCB assembly and is compatible with standard SMD pick-and-place lines. Typical applications include HVAC variable-air-volume (VAV) controllers, medical respiratory instruments (spirometers, ventilators), industrial process control, altitude and weather-station instrumentation, and consumer appliances such as washing-machine water-level monitors. The compound (-7 to +7 kPa) range is particularly valuable for measuring both vacuum and positive pressure relative to atmospheric reference, enabling bidirectional flow sensing across fans, and filter differential-pressure monitoring in ventilation ducts. When designing with this device, place a 0.1 uF decoupling capacitor close to the supply pin, keep the pressure-port tubing short to minimize pneumatic resonance, and protect the port from condensation and direct water exposure using a barrier membrane when needed.
