MPXV5010GC6U - 10kPa Vented Gauge Pressure Sensor | NXP
The NXP MPXV5010GC6U is a monolithic silicon piezoresistive pressure sensor delivering a calibrated analog output from 0.2 V to 4.7 V that is proportional to applied pressure in the 0 to 10 kPa (1.45 PSI) range, housed in an 8-pin SOP (Small Outline Package) with a top-port vented-gauge male tube inlet. It is part of the MPX5010/MPXV5010G series and operates from a single 5 V supply (4.75 V to 5.25 V). A pressure sensor is a transducer that converts an applied pressure into a measurable electrical signal; piezoresistive sensors use diffused strain gauges on a silicon diaphragm whose resistance changes with mechanical strain. The MPXV5010GC6U combines micromachined silicon, thin-film metallization, and bipolar signal conditioning to provide a temperature-compensated, calibrated, high-level analog output that interfaces directly to an MCU/MPU A/D input without external amplification. Key features include on-chip signal conditioning and temperature compensation, a high-level 0.2 V to 4.7 V ratiometric output that aligns with a 5 V ADC full-scale, a vented-gauge reference that compensates for ambient barometric pressure, and a top-port male tube inlet sized at 0.13 inch (3.17 mm) for hose or barb connections. 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.

MPXV5010GC7U - 0-10kPa Differential Pressure Sensor | NXP
The NXP Semiconductors MPXV5010GC7U is an integrated silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, delivering a calibrated analog output proportional to applied differential pressure from 0 kPa to 10 kPa in a surface-mount SOP-8 (Case 1737) package. 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. This page synthesizes verified distributor pricing, drop-in alternative candidates, application notes, and design considerations not consolidated on the manufacturer product page or distributor listing.
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.

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.

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.

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.

The STMicroelectronics MPXV7007GP is a monolithic silicon piezoresistive pressure sensor that measures compound pressures from -7 kPa to +7 kPa (-1.02 to +1.02 PSI) and converts them to a ratiometric analog output of 0.5 V to 4.5 V at 5 V supply. It is housed in an 8-pin Small Outline Package (SOP-8) with a top-side port and gull-wing leads for surface mounting. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a MEMS device that uses diffused strain gauges on a silicon diaphragm; when pressure is applied, the diaphragm flexes and changes the resistance of the gauges, producing a differential voltage proportional to applied pressure. Piezoresistive sensors sit within the hierarchy of pressure sensors -> MEMS sensors -> sensors -> electronic components, and are widely chosen for low-pressure medical, HVAC, and instrumentation uses because of their high sensitivity, low cost, and integrated signal conditioning. Key features of the MPXV7007GP include on-chip signal conditioning, factory calibration, temperature compensation from 0 °C to +85 °C, and a typical full-scale span of 4 V at 5 V supply. The device operates from a single 5 V supply (4.5 V to 5.5 V), draws 10 mA typical supply current, and includes EMC and reverse-polarity protection. The compound range allows both vacuum and positive pressure measurement with a single device, simplifying manifold and bidirectional flow designs. Technically, the MPXV7007GP uses bipolar processing with thin-film metallization combined with advanced micromachining to deliver an accurate, high-level analog output that interfaces directly to microcontroller A/D inputs without external compensation. The 0.5 V to 4.5 V output spans nearly the full ADC range of a 5 V MCU, maximizing resolution. Typical applications include HVAC variable-air-volume controls, medical respirators and ventilators, process controls, level sensing, and portable/wearable airflow monitoring. The compound range makes it ideal for measuring both positive and negative pressures in respiratory circuits and duct work. When designing with this part, place a 0.33 µF decoupling capacitor close to the supply pin and a small RC filter on the output if the ADC input is in a noisy environment. Avoid kinking or blocking the side port, and respect the maximum tube diameter of 0.13 in (3.17 mm) to prevent leaks.

MPXV7025DP - 5V ±25kPa Differential Pressure Sensor | NXP/ST
The NXP Semiconductors (originally Freescale, now also distributed by STMicroelectronics) MPXV7025DP is a state-of-the-art monolithic silicon piezoresistive pressure sensor rated for ±25 kPa (±3.63 PSI) differential measurement in a dual-port SOP 8 (8-BSOP, 12.06 mm width) package. It operates from a single 5 V supply and provides a temperature-compensated, calibrated analog output of 0.2 V to 4.7 V over the rated pressure range, ready to feed directly into a microcontroller ADC input. What is a differential pressure sensor? A differential pressure sensor measures the pressure difference between two ports (a high-side inlet and a low-side reference) and outputs a voltage proportional to that delta. It belongs to the pressure sensor family under MEMS (micro-electro-mechanical systems) and silicon piezoresistive transducers. Differential sensors are widely used for flow sensing (via orifice or pitot tube), filter blockage detection, altitude/altitude-derivative sensing, and HVAC duct monitoring, where only the difference between two points — not an absolute reference — matters. Key features include on-chip signal conditioning (no external calibration required), temperature compensation across 0 °C to +85 °C, ±5 % linearity over the primary pressure range, and a sensitivity of approximately 90 mV/kPa at 5 V excitation. The patented single-element transducer combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing — an architecture inherited from earlier Motorola/Freescale MPX series devices. Technically, the device uses a Wheatstone-bridge of piezoresistors diffused into a silicon diaphragm. When pressure is applied across the dual ports, the diaphragm flexes, unbalancing the bridge and producing a differential voltage that is then amplified and offset on-chip to the 0.2 V – 4.7 V output swing. The result is a ratiometric analog output that scales proportionally with supply voltage, simplifying ADC interface design with 3.3 V or 5 V microcontrollers. Typical applications include HVAC duct airflow monitoring, medical respirators and CPAP machines, industrial process control, water-level detection in sealed tanks, and altitude/altitude-derivative measurement in drones and wearables. Designers choose this part when they need a calibrated, drop-in analog solution rather than a digital I²C/SPI sensor. When designing in, place 100 nF decoupling close to the supply pin and use a stable, low-noise 5 V source — the output is ratiometric, so any supply ripple couples directly into the reading. Add a small RC low-pass filter on the output if driving long cables to suppress EMI pickup.

A pressure sensor is a transducer that converts an applied physical pressure into a proportional electrical signal. Within the broader sensor hierarchy, the MPXV7025DPT1 belongs to the piezoresistive family, where strain gauges embedded in a silicon diaphragm change resistance when mechanical stress is applied. It sits under MEMS (micro-electromechanical systems) sensors, which themselves are a sub-class of semiconductor sensors used in industrial, medical, and consumer monitoring. Differential variants, like this one, measure the pressure difference between two ports rather than absolute or gauge pressure, making them ideal for flow measurement and filter monitoring. Key features of the MPXV7025DPT1 include a 5.0 V typical supply, an on-chip signal conditioner and temperature compensation circuit, a ratiometric analog output, and a 0.475-inch (12.06 mm) wide 8-BSOP housing with two 0.13-inch (3.302 mm) male tube ports on the same side. The output span of 4.5 V across the ±25 kPa range gives approximately 90 mV per kPa sensitivity, simplifying firmware calibration on the host MCU. Technically, the device leverages Freescale's (now NXP) patented single-element transducer design, which provides a single piezoresistive die that responds symmetrically to positive and negative differential pressure. The integrated ASIC normalizes the offset, span, and temperature drift, eliminating the need for external compensation components. This monolithic integration delivers a typical total error of under 5% across 0 °C to 85 °C, suitable for closed-loop control without factory recalibration. Typical applications include HVAC variable-air-volume (VAV) controllers, patient monitoring airflow, process control manifolds, and water-level / filter-pressure detection. The differential topology allows bidirectional flow sensing when used with pitot tubes or orifice plates. The same-side dual port arrangement simplifies plumbing layout for inline measurement. When designing with the MPXV7025DPT1, take care to vent the unused port appropriately for gauge-style applications, and keep fluid-path tubing short and stiff to avoid mechanical resonance.

MPXV7025GC6T1 - ±25 kPa Pressure Sensor, 5V, Top Port | NXP
The NXP MPXV7025GC6T1 is an integrated silicon pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, housed in an 8-SMD gull-wing package with a top axial pressure port. The device measures gauge pressure from 0 to +25 kPa (0 to +3.63 PSI, compound range down to -25 kPa) and provides a ratiometric analog output of 0.2 V to 4.7 V from a 4.75 V to 5.25 V supply. The MPXV7025GC6T1 targets board-mount applications where a small, calibrated, factory-trimmed pressure-to-voltage transducer is required. A board-mount pressure sensor, also called a piezoresistive transducer or pressure sensor IC, is a semiconductor device that converts applied pressure into a proportional electrical signal. Within the broader hierarchy, this places it as a pressure sensor -> sensor -> transducer -> signal conditioning device. Piezoresistive sensors use a Wheatstone bridge of strain-sensitive silicon resistors etched into a diaphragm; when pressure deflects the diaphragm the bridge produces a differential voltage that is then amplified and offset on-chip. The integrated signal path of the MPXV7025GC6T1 eliminates external compensation circuitry, simplifying design-in. Key features include factory calibration across 0 to 85 °C, a low supply current of approximately 7 mA typical, an operating temperature range of -40 °C to +125 °C, and a top-side axial port that accepts 3.18 mm tubing for direct connection to the measured gas. The output is ratiometric with VDD, which means the full-scale span scales with supply voltage and allows simple ADC interfacing using the supply as the reference. The 8-SMD, gull-wing package simplifies SMT assembly and provides mechanical robustness for industrial environments. The MPXV7025 series piezoresistive transducer is built on a monolithic silicon process that integrates the sensing diaphragm, the Wheatstone bridge, and the signal-conditioning ASIC on a single die. The on-chip ASIC provides offset trimming, span calibration, and temperature compensation, so designers do not need to perform multi-point calibration in firmware. This architecture yields a typical accuracy within a few percent of full-scale span across the calibrated temperature range, which is sufficient for HVAC, medical respiratory, and appliance applications. Typical applications are HVAC damper control and airflow monitoring, medical respiratory equipment such as ventilators and CPAP machines, appliance pressure sensing including washing-machine water level and dishwasher flow, altimeters and barometric aids, and industrial pneumatic control. The 0.2 V to 4.7 V output swings nearly full-scale between the rails and is well matched to 5 V ADCs and microcontrollers. When designing with this device, ensure the supply is well regulated because the output is ratiometric: noise or drift on VDD appears directly on VOUT. Place a 100 nF decoupling capacitor close to the VDD pin and a small capacitor on the output if the load is highly capacitive. The axial port accepts 3.18 mm tubing; use flexible silicone or polyurethane tubing with a press fit, and avoid kinking the line near the port.

Key features include on-chip signal conditioning, temperature compensation between 0 °C and 85 °C, and calibration that eliminates the need for external trim components. The 5 V typical supply with ratiometric output (VOUT/VCC scaling) provides 90 mV/kPa nominal sensitivity over the full ±25 kPa span, plus ±5 % accuracy after calibration. The patented single-element transducer combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing to deliver stable, repeatable performance with long-term drift typically below 1 % per year. Typical applications include HVAC variable-air-volume (VAV) controllers, medical respiratory and vacuum equipment, industrial process control, altimeters and variometers, and engine manifold absolute/relative pressure sensing. The 8-SMD top-port package simplifies pneumatic connection via 3.18 mm (0.13 in) tubing while keeping the PCB-side reflow-compatible. When designing with this device, ensure that the analog supply (VCC) is well decoupled with a 100 nF ceramic capacitor placed within 5 mm of the supply pin, and avoid sharp tubing bends at the axial port to prevent stress on the package. The output is ratiometric to VCC, so any noise on the 5 V supply will translate directly into output noise — use a low-noise LDO for best results.

The MPXV7025GP belongs to the integrated silicon pressure sensor family (piezoresistive transducer -> MEMS pressure sensor -> pressure sensor -> sensor IC), combining a micromachined silicon diaphragm with on-board ASIC conditioning. This integration eliminates the need for external amplification or temperature compensation circuitry, simplifying design-in for engineers. Key features include a compound pressure range allowing both positive and vacuum measurement, a ratiometric analog output suitable for 5V supply systems, and factory calibration that removes user-side trimming. The device operates over a wide supply voltage with low power consumption and provides temperature-compensated output across its specified operating range. Its integrated signal chain produces a clean analog voltage that maps linearly to applied pressure, reducing software overhead. The MPXV7025GP is built using NXP's proprietary MEMS piezoresistive technology combined with a bipolar op-amp signal-conditioning ASIC. The Wheatstone bridge formed by implanted resistors on the silicon diaphragm produces a differential millivolt signal that is amplified, offset-corrected, and temperature-compensated to deliver a ground-referenced 0.2 V to 4.7 V swing. This single-chip integration dramatically improves noise immunity compared to discrete transducer designs. Typical applications include HVAC air-flow monitoring, respiratory equipment, barometric compensation for altimeters, process control systems, and medical vacuum/pressure monitoring. The compound range enables measurement in systems that see both pressure and vacuum. When designing with this part, decouple the VCC pin with a 100 nF ceramic capacitor placed close to the sensor leads. The output is ratiometric to VCC, so for highest accuracy, ADC read the regulator should share the same supply rail as the sensor or use a precision reference.

From an architectural standpoint, the MTCH105 uses a charge-transfer measurement front-end coupled with a digital signal-processing engine that runs the noise-suppression optimization algorithm on each measurement cycle. The MTSA pin selects sensitivity presets, and the MTPM pin sets the active scan rate vs low-power standby trade-off. The active guard signal is driven in phase with the sensing waveform, cancelling parasitic capacitance to the sensor pad and dramatically extending touch range. The five open-drain (or push-pull, depending on datasheet configuration) outputs are simple logic-level signals that drive downstream MOSFETs, optocouplers, or GPIO inputs directly. Typical applications for the MTCH105-I/ST include replacing mechanical buttons on white goods, audio mixer faders and rotary controls, smart-lighting wall switches, access-control keypads, proximity wake-up sensors in IoT nodes, and consumer remote-control touch surfaces. The TSSOP-14 footprint supports compact PCB layouts and is well suited to cost-sensitive designs. When designing with the MTCH105-I/ST, place sensor pads on a top-layer copper pour with a thin dielectric overlay (typically 1-3 mm of plastic or glass), keep sensor traces short and surrounded by ground, and add a series resistor (typically 4.7 kohm to 47 kohm, see datasheet) near each sensor pin for noise immunity.
