MPX4250A - 250 kPa MAP Pressure Sensor, On-Chip Conditioned | NXP
The NXP MPX4250A is an integrated silicon manifold absolute pressure (MAP) sensor with on-chip signal conditioning, temperature compensation, and calibration, delivered in a 6-lead SIP module. It measures absolute pressure from 20 to 250 kPa (2.9 to 36.3 PSI) and produces a ratiometric analog output of approximately 0.2 V to 4.9 V proportional to the applied pressure and the supply voltage. A manifold absolute pressure sensor is a piezoresistive transducer that converts an absolute pressure referenced to a sealed internal vacuum into a calibrated voltage. MAP sensors sit at the boundary between physical sensing and electronic signal conditioning, providing a high-level analog output that connects directly to an ECU's analog-to-digital input. They form a key subcategory of board-mount pressure sensors within the broader sensor hierarchy: pressure sensor -> transducer -> sensor IC -> signal conditioning IC -> semiconductor. Key features of the MPX4250A include a maximum pressure rating of 1000 kPa, supply voltage range of 4.85 V to 5.35 V (typically 5.0 V), sensitivity of approximately 18.4 mV/kPa, response time of 1.0 ms, and a full operating temperature range of -40 C to +125 C. The monolithic silicon die uses piezoresistive bridges fabricated with bipolar-compatible thin-film metallization and micromachined diaphragms. The output transfer function is approximately VOUT = VSUPPLY x (0.004 x P - 0.04) - 0.04 V + VSUPPLY x 0.04 with the supplied transfer function Vout = Vsup x (0.01058 x P - 0.1518), where P is pressure in kPa. At 5.0 V supply, 0 kPa produces nominally 0.25 V, 100 kPa produces about 2.45 V, 200 kPa produces about 4.65 V, and 250 kPa produces 4.90 V. The on-chip temperature compensation holds accuracy within the datasheet-specified error band across the full -40 C to +125 C automotive-grade window. Typical applications include automotive engine control units, where the MAP sensor feeds the ECU for air-mass calculation and fuel injection timing, motorcycle and small-engine fuel injection, industrial vacuum monitoring, altitude-corrected barometric pressure measurement, and HVAC blower-pressure feedback loops. The wide 250 kPa span aligns naturally with naturally-aspirated gasoline intake manifolds and the 1.0 atmosphere operating point of sealed-vacuum-referenced MAP designs. When designing with this part, place a small RC low-pass filter at the Vout pin to suppress high-frequency EMC artifacts, and ensure the pneumatic port is sealed against moisture. Because the part uses a sealed vacuum reference and absolute pressure measurement, no altitude correction at installation is required - which differs from gauge-pressure sensors requiring vent tubes. The datasheet provides a complete transfer function polynomial plus worst-case error band including nonlinearity, temperature hysteresis, and pressure hysteresis.

MPX4250AP - 250 kPa Absolute Pressure Sensor | NXP | 6-SIP
The NXP MPX4250AP is a Manifold Absolute Pressure (MAP) sensor that measures absolute pressure from 20 kPa to 250 kPa with on-chip signal conditioning, temperature compensation and calibration, housed in a 6-SIP through-hole module with 0.19 inch (4.93 mm) tube inlet. It delivers a ratiometric analog output of 0.2 V to 4.9 V from a 5 V supply, suited for engine control and HVAC applications. An absolute pressure sensor is a transducer that converts applied pressure (with an internal vacuum reference) into a calibrated analog voltage proportional to absolute pressure rather than gauge pressure. As a member of the MAP sensor family, it sits within the broader pressure sensor -> sensor -> transducer hierarchy and is commonly integrated into engine control units (ECUs), industrial pneumatic controllers, and barometric instrumentation. Key features include a 20 kPa to 250 kPa (2.9 psi to 36.26 psi) absolute pressure range, 5.0 V nominal supply, ratiometric 0.2 V to 4.9 V analog output, on-chip temperature compensation across -40C to +125C, and EMC robustness for automotive electrical environments. The integrated signal chain eliminates the need for external op-amps or trims. The MPX29951 family uses a piezoresistive silicon strain gauge on a diaphragm. When pressure deflects the diaphragm, the integrated Wheatstone bridge produces a differential voltage that is amplified, temperature-compensated and calibrated on-chip to produce a linear, ratiometric output (VOUT/VCC proportional to P/PIN). This produces a robust, calibrated analog signal directly usable by an MCU ADC without further linearization. Typical applications include automotive engine manifold absolute pressure sensing for fuel injection control, barometric pressure compensation, industrial vacuum measurement, HVAC pressure monitoring, and altitude correction in motorcycle/powersport ECUs. The wide 20-250 kPa range covers naturally aspirated and moderately boosted engines. When designing with this sensor, observe the tube inlet geometry (0.19 inch / 4.93 mm OD) and avoid sharp bends that could cause turbulence. Apply a 5.0 V regulated supply and decouple with a 100 nF capacitor near the VCC pin. Mount away from heat sources such as exhaust manifolds to limit thermal drift.

MPX4250D - 250 kPa Differential Pressure Sensor 0.2-4.9 V | NXP/ST
The MPX4250D is a state-of-the-art monolithic silicon piezoresistive pressure sensor delivering a calibrated differential analog output of 0.2 V to 4.9 V for pressures from 0 kPa to 250 kPa (0 to 36.26 psi). It integrates on-chip signal conditioning, temperature compensation, and calibration, and is supplied in a 6-lead SIP (Single In-line Package) module designed for through-hole or vertically-mounted PCB insertion. A pressure sensor of this type is a transducer that converts an applied differential pressure into a proportional analog voltage. Within the broader sensor taxonomy, the MPX4250D sits in the piezoresistive silicon pressure sensor family, a sub-class of MEMS sensors, which itself belongs to the wider group of analog transducers used for physical-parameter measurement in industrial, automotive, and consumer systems. The on-chip signal conditioning eliminates the need for external amplification or trimming, allowing direct connection to a microcontroller ADC input. Key specifications include a 0.2 V to 4.9 V ratiometric analog output over 5.0 V typical supply, a 4.7 ms response time, a 1.0 % full-scale error over 0 to 85 °C, and a typical full-scale span of 4.7 V. The sensor is temperature-compensated across -40 °C to +125 °C, making it suitable for under-hood automotive environments as well as industrial process monitoring. It uses dual longitudinal pressure ports for differential measurement referenced to atmospheric or vacuum pressure. Internally, the MPX4250D uses a thin-film metallization layer on a micromachined silicon diaphragm whose resistance changes with strain. The Wheatstone bridge formed by the diffused piezoresistors is laser-trimmed during manufacture for span and offset, so the device needs no user calibration. The bipolar signal-conditioning path then amplifies the differential bridge voltage to the calibrated 0.2-4.9 V swing at 5.0 V supply. Typical applications include automotive manifold absolute pressure (MAP) sensing for turbo-boost and engine control, HVAC differential pressure measurement, industrial pneumatics, altimeters and barometric instruments, and consumer appliance pressure feedback. In automotive engine control units (ECUs) the calibrated linear output maps directly to manifold pressure for fuel-injection timing. A key design consideration is that the output is ratiometric to the supply voltage: with a stable 5.000 V reference, the output scales linearly; if the supply drifts ±5 %, the output error is roughly ±5 %. Using an ADC reference derived from the same 5 V rail preserves ratiometric accuracy and avoids calibration drift.

MPX4250DP - 0-250 kPa Differential Pressure Sensor | NXP
The NXP MPX4250DP is an integrated silicon piezoresistive pressure sensor delivering a calibrated, temperature-compensated analog output from 0 kPa to 250 kPa (0 to 36.3 psi) in a 6-lead SIP (Single In-line Package) module with dual pressure ports (differential). It produces a ratiometric analog output of 0.2 V to 4.91 V (typical) proportional to applied pressure, operates from a single 4.85 V to 5.35 V supply, and is designed for direct connection to a microcontroller A/D input. A piezoresistive pressure sensor is a transducer that converts an applied mechanical pressure into an electrical signal by exploiting the change in resistance of silicon strain gauges implanted in a diaphragm. Within the broader sensor taxonomy, the MPX4250DP belongs to the analog output pressure sensor family, which sits under MEMS sensors and alongside digital I2C/SPI pressure sensors, force sensors, and strain gauges. The on-chip signal conditioning, calibration, and temperature compensation distinguish this part from raw sensor elements that require external instrumentation amplifiers and reference design correction. Key features include ±1.5% maximum pressure error over 0-85°C, an output voltage swing from 0.2 V to 4.91 V for maximum A/D resolution on a 5 V rail, on-chip temperature compensation from -40°C to +125°C, and EMI hardening. The dual-port (DP) differential configuration allows measurement across two pressure sources rather than against sealed reference. The 6-SIP through-hole package is compatible with automotive wiring harnesses and industrial manifolds. The MPX4250DP combines micromachined silicon diaphragm technology with thin-film metallization and bipolar signal conditioning on a single monolithic die. This integration yields a calibrated transfer function (typically VOUT = VS × (0.004 × P - 0.04), where P is pressure in kPa) and eliminates the need for external temperature lookup tables, making it well suited for cost-sensitive engine control units. Typical applications include automotive engine manifold absolute pressure (MAP) sensing, barometric correction for fuel injection, industrial pneumatic pressure monitoring, HVAC duct pressure measurement, and consumer appliance pressure feedback. The wide temperature range and ratiometric output make it a fit for under-hood automotive ECU environments. When designing with this device, route supply and ground with low-impedance traces and decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin to limit switching noise on the ratiometric output. Limit exposure to humidity and condensing media by mounting the ports vertically downward or by adding a hydrophobic vent membrane.

MPX4250GP - 250kPa Vented Gauge Pressure Sensor | NXP Semiconductors
The NXP Semiconductors MPX4250GP is a piezoresistive silicon pressure sensor rated for a 250 kPa (36.26 PSI) vented-gauge pressure range, housed in a 6-SIP module with a 4.93 mm (0.19 inch) barbed tube inlet and ratiometric analog output from 0.2 V to 4.9 V. It delivers on-chip signal conditioning, calibration, and temperature compensation, producing 18.8 mV/kPa nominal sensitivity across a 4.85 V to 5.35 V supply range, designed primarily for automotive engine control. A vented-gauge pressure sensor is a transducer that converts an applied pressure (relative to a vented reference, typically atmosphere) into an electrical signal; the silicon die uses piezoresistive strain gauges whose resistance changes with membrane deflection. Modern integrated pressure sensors like the MPX4250GP place the strain-gauge bridge, signal amplifier, temperature-compensation network, and calibration EEPROM on a single monolithic die, eliminating the external compensation circuit required by earlier raw-bridge sensors. In a typical engine-control ECU the device sits downstream of the inlet manifold, providing one of two key inputs (the other being air temperature) to the speed-density air-mass calculation. Key features include 0.2 V to 4.9 V ratiometric output, 18.8 mV/kPa sensitivity, 0 to 250 kPa (36.26 PSI) operating range, and integrated ASIC signal conditioning. The package is a 6-pin SIP (Single Inline Package) module with a vertical port for tube-mounting and a barbed pressure inlet. Typical applications include automotive manifold absolute pressure (MAP) sensing, turbo boost pressure monitoring, industrial process pressure measurement, and HVAC duct pressure sensing. The wide 0-250 kPa range supports both naturally aspirated and boosted engines. When designing with this device, ensure the 5V supply is well-regulated, decouple VCC with 100 nF ceramic close to the pin, and protect the port from water and debris ingress; the vented-gauge design requires the rear vent to remain unobstructed for accurate atmospheric reference.
MPX5010D - 10kPa Differential Pressure Sensor | NXP Semiconductors
The NXP Semiconductors MPX5010D is a monolithic silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation and calibration, providing a linear analog output proportional to applied differential pressure from 0 kPa to 10 kPa (0 to 1.45 PSI) in a 6-pin SIP Module (Case 867-08). A piezoresistive transducer is a solid-state sensor that converts applied mechanical pressure into a proportional change in resistance of diffused silicon strain gauges arranged in a Wheatstone bridge. The MPX5010D belongs to the pressure-sensor / transducer family in the broader Sensors hierarchy, which itself sits within MEMS (Micro-Electro-Mechanical Systems). The integration of signal conditioning, temperature compensation and calibration directly on-chip distinguishes this part from raw Wheatstone-bridge sensing elements that require external amplifiers and trimming. Key features include a 0.2 V to 4.7 V ratiometric analog output proportional to 5 V supply, a 4.75 V to 5.25 V supply range, a typical full-scale span of 4.5 V at 10 kPa, and a measured accuracy suitable for medical, industrial and consumer flow or level sensing applications. The device is engineered to interface directly with microcontrollers or microprocessors equipped with A/D inputs, eliminating the need for additional front-end analog circuitry in most designs. At the architecture level the sensor combines advanced surface micromachining, thin-film metallization for the strain-gauge network, and bipolar signal-conditioning circuitry fabricated on the same silicon die. Temperature compensation and span calibration are laser-trimmed at the wafer level, so each part delivers a closely-matched transfer function across the 0C to +85C operating range. The differential pressure port geometry routes positive pressure to the top side of the diaphragm and reference pressure to the underside. Typical applications include HVAC duct airflow measurement, medical respirator and ventilator flow paths, liquid level detection in non-corrosive reservoirs, industrial process control loops, barometric baseline correction in altimetry modules, and appliance water-level feedback. The differential configuration enables bidirectional flow sensing across an orifice or venturi element. When designing with the MPX5010D, place a 0.1 uF decoupling capacitor within a few millimeters of the supply pin and use a stable 5 V reference for the ADC if absolute pressure accuracy beyond the ratiometric spec is required. Avoid exposure to harsh media - the silicon diaphragm is exposed through the port and should be protected with a compatible media-isolating cap in liquid applications.

MPX5010DP - 10kPa Differential Pressure Sensor, 5V | NXP/ST
The NXP MPX5010DP is an integrated silicon piezoresistive pressure sensor delivering a precise differential pressure measurement from 0 to 10 kPa (0 to 1.45 PSI) with on-chip signal conditioning, temperature compensation and calibration, housed in a 6-lead SIP module with dual 4.93 mm pressure ports. A piezoresistive pressure transducer is a solid-state sensor that converts applied gas or air pressure into a strain-induced change in resistance, which is then conditioned on-chip into a ratiometric analog output voltage proportional to pressure. The MPX5010DP belongs to the MPxx5010 family of monolithic silicon pressure sensors, situated in the broader hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor IC -> semiconductor. It is intended for systems employing a microcontroller or microprocessor with an A/D converter, where it replaces discrete bridge amplifiers and trimming circuits with a single calibrated device. Key specifications include a full-scale span of 10 kPa, a sensitivity of 450 mV/kPa typical, an output range of 0.2 V to 4.7 V at 5 V supply, and a 5 V typical supply voltage (4.75 V to 5.25 V). The integrated bipolar signal chain delivers better than +/-1.5% linearity over the compensated temperature range of 0 to 85 C, while factory calibration removes the need for external passive trim networks. The dual-port (DP) mechanical configuration supports differential measurement between two air or non-corrosive gas sources. Architecturally, the device combines a micromachined silicon diaphragm with thin-film metallization and bipolar signal processing on a single die. This monolithic integration is what enables its calibrated, temperature-compensated output without external components. The 6-SIP package provides two axial ports for differential pressure connection and four through-hole leads for power, ground, and analog output, simplifying PCB assembly. Typical applications include HVAC variable-air-volume controllers, medical respiratory and CPAP monitors, industrial process control, water-level / liquid-level sensing via trapped air columns, altitude and barometric measurement, and consumer appliance pressure feedback. The differential topology is particularly suited to measuring pressure drop across filters, ducts, orifices, and small fans. When designing with the MPX5010DP, decouple the supply with a 100 nF ceramic capacitor placed within 5 mm of the VCC pin and provide a stable 5 V rail, since the output is ratiometric. Keep both pressure ports free of moisture, particulates, and corrosive media; for liquid sensing, isolate the sensor via an air column or use the MPVZ5010 family with media-resistant gel.

MPX5010GP - 0-10kPa Vented Gauge Pressure Sensor | NXP
The NXP MPX5010GP is an integrated silicon piezoresistive pressure sensor that delivers a calibrated, temperature-compensated analog output for gauge pressures from 0 to 10 kPa (0 to 1.45 PSI). Housed in a 6-SIP through-hole module with a 0.19" (4.93 mm) male tube port for vented gauge measurements, it accepts a 5 V supply and produces a ratiometric output spanning approximately 0.2 V to 4.7 V, providing 4.5 V of useful dynamic range that maps directly onto the input range of most 5 V ADCs. What is a gauge pressure sensor? A gauge pressure sensor measures pressure referenced to ambient atmospheric pressure through a vent port, distinguishing it from absolute sensors (which reference a sealed vacuum) and differential sensors (which measure between two ports). Within the broader sensor hierarchy, the MPX5010GP sits as a pressure transducer in the sensors category, where piezoresistive MEMS technology dominates low-pressure applications due to its high sensitivity, small size, and CMOS-compatible signal conditioning. Key features include on-chip signal conditioning that eliminates the need for external amplification, factory calibration that reduces part-to-part variation to approximately ±1.5% per the datasheet, and integrated temperature compensation from 0 °C to 85 °C. The 0.2 V to 4.7 V ratiometric output is referenced to the 5 V supply, ensuring noise immunity and accurate conversion when paired with a 5 V ADC reference. The sensor combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing on a single monolithic die. A piezoresistive bridge etched into the silicon diaphragm converts mechanical strain into a millivolt-level differential signal, which the on-chip ASIC amplifies, calibrates, and linearizes to produce the final analog output with minimal user-side conditioning. Typical applications include medical respiratory monitoring such as CPAP and spirometry, HVAC differential pressure sensing, industrial process control, vacuum cleaner and appliance load sensing, and altitude estimation in drones and portable instruments. The combination of low-pressure sensitivity and analog ratiometric output makes the MPX5010GP especially useful where ADC integration is straightforward and battery life is not the primary constraint. When designing with this part, take care to mount the SIP package vertically on the PCB so the port faces downward or sideways, matching the recommended manifold geometry in the datasheet to avoid pressure measurement errors caused by port orientation. Decouple the 5 V supply with a 100 nF ceramic capacitor placed close to the sensor supply pin to suppress switching noise from downstream digital circuitry.

MPX5010GS - 10kPa Gauge Pressure Sensor, 5V, 6-SIP | NXP
The NXP Semiconductors MPX5010GS is an integrated silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, delivering a 0.2 V to 4.7 V analog output proportional to applied pressure over a 0 to 10 kPa (0 to 1.45 PSI) gauge range. It operates from a single 5 V supply, draws 5 mA typical current, and is housed in a 6-pin axial SIP (Case 867E-03) module with a male 0.19" (4.93 mm) tube pressure port for external hose connection. The transducer combines a monolithic silicon sensing diaphragm, a custom ASIC amplifier, and factory calibration coefficients to provide a ratiometric analog output ready to feed directly into an MCU ADC input. A pressure sensor is a transducer that converts an applied pressure into a proportional electrical signal, typically for display, control, or data-acquisition purposes. The MPX5010GS belongs to the piezoresistive pressure sensor family - meaning the sensing element changes its electrical resistance when mechanically strained by pressure - within the broader sensor hierarchy of pressure transducers -> pressure sensors -> sensors -> electronic components. The on-chip signal chain converts the millivolt-level bridge output into a low-impedance, ground-referenced 0.2 V-4.7 V signal, so engineers do not need to add external instrumentation amplifiers or temperature compensation circuits. Key features include a maximum pressure rating of 75 kPa, an accuracy of +/-2.5% of full-scale span over 0 C to +85 C, and a typical response time of 1.0 ms. The ratiometric analog output (Vout = VS * (0.092 * P + 0.072) where P is kPa and VS is the 5 V supply) ties the output directly to the supply voltage, so ADC readings remain stable as VDD fluctuates. The 6-SIP axial package and integral tube port simplify tubing and chassis-mount integration in medical, HVAC, and consumer appliance designs. The internal architecture uses a single-chip silicon strain-gauge bridge diffused into a diaphragm, then laser-trimmed at the factory so each MPX5010GS ships pre-calibrated to the published transfer function. Temperature compensation is also baked in across the 0 C to +85 C compensated range, eliminating the need for software-based temperature lookup tables in most designs. The amplifier stage is designed for low noise (1 mV RMS typical) and high immunity to supply ripple. Typical applications include medical respiratory and continuous positive airway pressure (CPAP) monitors, HVAC duct-pressure sensing, appliance water-level/flow measurement, industrial process control loops, and barometric reference for weather stations. The wide supply tolerance (4.75 V to 5.25 V) makes the part tolerant of loosely regulated rails, and the standard 5 V analog output simplifies integration with both 5 V MCUs and 3.3 V MCUs via a simple resistor divider. When designing with the MPX5010GS, ensure the PCB layout isolates the analog ground return from noisy digital grounds to prevent switching-noise injection into the high-impedance bridge. Use a 470 nF to 1 uF decoupling capacitor close to the supply pin, and route the output through a low-pass RC filter (10 kHz corner) if the MCU ADC is exposed to broadband noise. Do not exceed 75 kPa or the part will saturate and may be permanently damaged.

MPX5010GS117 - 10 kPa Pressure Sensor, 0-45°C | NXP | Industrial
The NXP MPX5010GS117 is a monolithic silicon piezoresistive pressure sensor designed for accurate measurement of differential or gauge pressure in the 0 to 10 kPa range. Packaged in a surface-mount SOP-8 configuration with two axial pressure ports, the device integrates on-chip signal conditioning and temperature compensation, delivering a calibrated analog output proportional to applied pressure. A piezoresistive pressure sensor is a transducer that converts applied mechanical pressure into a proportional electrical signal using strain-sensitive resistors diffused into a silicon diaphragm. When pressure deflects the diaphragm, the Wheatstone bridge changes resistance and produces a differential output voltage. Integrated temperature-compensation and calibration circuitry then linearizes and scales that output, allowing designers to read pressure directly without extensive external analog signal processing. Within the broader sensor hierarchy, this places MPX5010GS117 as a pressure sensor, a subclass of MEMS (Micro-Electro-Mechanical Systems) devices, which themselves belong to transducer and signal-conditioning semiconductors. Key features include a 0 to 10 kPa full-scale pressure range, a typical full-scale span of 45 mV per 1 kPa, a linearity of ±0.05 %VFSS per datasheet, and a compensated temperature range of 0°C to +85°C. The device also features a sensitivity of 4.5 mV/kPa, a response time of 1 ms, and operates from a single 5 V supply drawing approximately 5 mA. The SOP-8 surface-mount package simplifies PCB assembly for high-volume industrial designs. The MPX5010GS117 employs a single-port axial-pressure architecture with dual vertical ports on the same side of the package. The integrated laser-trimmed resistor network minimizes offset and span error without user adjustment, reducing BOM cost and calibration time. The device delivers an ratiometric analog output that can be fed directly into an ADC, eliminating the need for dedicated front-end amplifiers. Typical applications include HVAC air-flow and duct pressure monitoring, medical respiratory equipment, process control instrumentation, level measurement of non-corrosive gases, and altimeter/barometric pressure systems. The small SOP-8 footprint suits compact industrial modules and battery-powered instruments. When designing with this part, ensure the input pressure medium is compatible with the silicon gel and housing materials. Provide adequate reference-air venting through the second port and avoid contamination from particulates or condensing moisture. Add input protection for environments with overpressure transients beyond the 75 kPa maximum rating.

MPX5010GSX - 10kPa Integrated Pressure Sensor 6-SIP | NXP
The NXP MPX5010GSX is an integrated silicon pressure sensor with on-chip signal conditioning, temperature compensation and calibration, delivering a 0.2 V to 4.7 V analog output over a 0 kPa to 10 kPa (0 to 1.45 PSI) gauge pressure range in a 6-SIP module with a side-mounted 0.19 inch (4.93 mm) tube port. The transducer uses a monolithic piezoresistive strain-gauge bridge laser-trimmed for tight span accuracy and a precision ASIC that provides amplification, offset correction and thermal compensation across 0 C to 85 C. What is an integrated silicon pressure sensor? An integrated silicon pressure sensor is a MEMS device that converts applied pressure into an electrical output on a single silicon die, integrating the mechanical sensing element (typically a piezoresistive bridge etched into a silicon membrane) with active signal-conditioning electronics. These sensors sit in the broader hierarchy of pressure transducers -> MEMS sensors -> sensors -> electronic components. Compared to bare piezoresistive cells, integrated parts eliminate the need for external op-amp gain stages, temperature compensation and offset trim circuits, simplifying MCU-based designs. Key features of the MPX5010GSX include a 4.5 V to 5.5 V supply range, 0.2 V to 4.7 V ratiometric output spanning the full calibrated range, 1.0 % typical accuracy and a response time under 2 ms. The device is factory calibrated, RoHS compliant and qualified for automotive and industrial HVAC/medical instrumentation. Its vented gauge configuration references the back side of the diaphragm to ambient, simplifying board-level mounting and hose connections. Technically, the MPX5010GSX exploits a single-axis X-flow port geometry: media enters the side tube, presses on the topside of the diaphragm, while the underside of the die is exposed through a vent hole to local atmospheric pressure. The on-chip ASIC supplies a 1.0 mA excitation to the bridge, conditions the differential signal with chopper-stabilized gain stages and drives a low-impedance ratiometric output that scales with VCC, allowing ADC measurements to compensate for supply variation. Typical applications include HVAC blower and duct pressure sensing, blood pressure monitors, respirators and ventilators, level and flow instrumentation, appliance pressure feedback and process-control analog front ends. The 5 V single-supply operation and standard 0.2 V to 4.7 V output span map directly to most MCU ADC input ranges. When designing with the MPX5010GSX, place a 0.1 uF decoupling capacitor close to the supply pin, keep the vent port clear of obstructions and protect the side tube from liquid ingress with an inline hydrophobic filter when measuring humid media. Account for the 5 ms settling time when designing sample-and-hold windows for slow-moving control loops.

MPX5050D - 50kPa Differential Pressure Sensor, 5V, SIP-6 | NXP
The NXP Semiconductors MPX5050D is a monolithic, signal-conditioned silicon piezoresistive pressure sensor that measures differential pressure from 0 to 50 kPa (0 to 7.25 PSI) and produces a ratiometric analog output of 0.2 V to 4.7 V from a single 5 V supply, housed in a 6-pin SIP (Single In-line Package) module. The MPxx5050 family integrates on-chip bipolar op-amp circuitry and thin-film resistor networks that provide high output swing, active temperature compensation from 0 °C to +85 °C, and full calibration, eliminating the need for external signal conditioning in most microcontroller designs. A pressure sensor is a transducer that converts an applied pressure differential into an electrical signal. The MPX5050D belongs to the category hierarchy of pressure sensors > transducers > sensors > signal acquisition components, and the broader family of MEMS (Micro-Electro-Mechanical Systems) devices in which a micromachined silicon diaphragm flexes under differential pressure, changing the resistance of piezoresistive bridges. The on-chip signal chain amplifies and calibrates this bridge output to a precise ratiometric voltage that is directly readable by an analog-to-digital converter (ADC) or microcontroller A/D input. Key features include a 5 V typical supply (4.75 V to 5.25 V maximum range), 7 mA supply current at full scale, 1 ms response time, ±1.5% linearity over 0 to 50 kPa, and an internal ASIC that corrects temperature coefficients across the operating range. The 6-SIP through-hole module with integral pressure port is rated for non-corrosive, non-ionic media such as clean dry air, and its small form factor simplifies mounting in medical, industrial, and consumer instrument enclosures. The device uses on-chip bipolar op-amp signal conditioning and laser-trimmed thin-film resistors to calibrate offset, full-scale span, and temperature compensation. Compared with discrete pressure-to-bridge + amplifier implementations, the integrated approach eliminates gain and offset drifts that would otherwise require periodic recalibration in the field, while keeping the BOM cost comparable to a bare piezoresistor element plus an instrumentation amplifier. Typical applications include HVAC blower pressure sensing, respirator/ventilator airflow monitoring, industrial process control, water-level sensing via bubbler systems, and engine manifold absolute pressure (MAP) sensing on small engines. Designers frequently pair the MPX5050D with an NXP Kinetis or STMicroelectronics STM32 ADC input through a simple RC anti-aliasing filter. When designing with this part, note that the SIP-6 package and integral port are optimized for through-hole PCB assembly with a 2.54 mm pin pitch; the differential pressure port accepts 4.93 mm tubing (1/16 inch ID), and a properly oriented flow direction (P1 > P2 for positive output) is essential to avoid inverted readings. Supply bypass with a 100 nF ceramic capacitor placed within 25 mm of the supply pin is recommended to suppress injected noise from downstream digital circuits.

MPX5050DP - 50kPa Differential Pressure Sensor 6-SIP | NXP
The NXP MPX5050DP is a state-of-the-art monolithic silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, housed in a 6-SIP through-hole module with dual pressure ports. It measures differential pressure from 0 to 50 kPa (0 to 7.25 PSI) and provides an analog output of 0.2 V to 4.7 V from a single 5 V supply, with a typical full-scale span of 4.5 V. The sensor uses advanced micromachining, thin-film metallization, and bipolar processing to deliver a ratiometric analog signal that interfaces directly with microcontroller A/D inputs. A piezoresistive pressure sensor is a transducer that converts an applied pressure into a measurable electrical signal by exploiting the piezoresistive effect in silicon - the change in resistance of a diffused strain gauge when mechanical stress is applied to a silicon diaphragm. Within the broader sensor hierarchy, the MPX5050DP sits under MEMS sensors -> pressure sensors -> differential pressure sensors -> signal-conditioned pressure transducers. The integrated bipolar op-amp and thin-film resistor network on the die provide a temperature-compensated, calibrated output, eliminating the need for external analog signal-chain components in most applications. Key features include a pressure range of 0 to 50 kPa differential, full-scale span of 4.5 V typical (0.2 V to 4.7 V), 5 V single-supply operation, sensitivity of 90 mV/kPa typical, accuracy of ±2.5% over 0C to 85C, and overpressure capability of 200 kPa. The 6-SIP package includes two parallel 4.93 mm (0.19") tubes for hose connection, simplifying mechanical integration in fluidic systems. Ratiometric output tracks supply voltage variations for noise-immune ADC reading. Typical applications include HVAC blower and filter monitoring, automotive manifold absolute pressure sensing, medical respiratory instruments, industrial process control, level detection, and consumer appliance flow measurement. The dual-port differential configuration is particularly well suited to measuring pressure drop across flow restrictors, filters, and heat exchangers. When designing with this device, ensure that the high-impedance Vout pin is buffered with an op-amp or fed directly to a microcontroller A/D input. Decouple VCC locally with 100 nF ceramic bypass, keep the pressure ports sealed to the reference atmosphere on the low side, and avoid exposing the die to condensing humidity or condensing air conditions. The tube-port orientation simplifies pneumatic plumbing but requires a small PCB cutout or off-board mounting to provide port access.

MPX5050GP - 0-50kPa Vented Gauge Pressure Sensor | NXP
The NXP MPX5050GP is a monolithic piezoresistive silicon pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, housed in a 6-SIP module with a 0.19 inch (4.93 mm) male tube port for vented gauge measurement of 0 to 50 kPa (0 to 7.25 PSI). An integrated silicon pressure sensor is a transducer that converts an applied pressure into a proportional analog voltage using a piezoresistive strain gauge bridge etched directly into a silicon die, with on-chip op-amp and thin-film resistor networks providing amplification, temperature compensation, and calibration. In the broader sensor hierarchy, this part is a pressure sensor (synonym: pressure transducer), which falls under the MEMS sensor category and ultimately the sensor/transducer family of electronic components, interfacing to a microcontroller or ADC. Key features include a ratiometric analog output from 0.2 V to 4.7 V over the specified pressure range, 2.5 percent maximum accuracy (per the verified distributor data), 7 mA nominal supply current, and an operating temperature range of -40 C to +125 C. The sensor is designed for 5 V nominal supply (4.75 V to 5.25 V), with a maximum overpressure rating of 7 PSI (approximately 2x the full-scale range) per typical MPX5050 family ratings. The MPX5050GP uses a bipolar op-amp architecture combined with laser-trimmed thin-film resistors to deliver a high-level output signal and accurate temperature compensation across its operating range. The vented gauge (GP) configuration references the rear side of the die to ambient atmosphere, providing absolute differential measurement relative to barometric pressure for applications such as altitude estimation or vacuum-relative sensing. Typical applications include HVAC pressure monitoring, respiratory/medical equipment, level measurement, altitude estimation for drones or portable devices, and industrial process control where a clean 5 V rail-driven analog pressure signal is required. The automotive-qualified variants within the MPX5050 family make this family popular for manifold absolute pressure (MAP) sensing and barometric absolute pressure (BAP) sensing applications. When designing with this device, ensure a stable, low-noise 5 V supply because the output is ratiometric. Decoupling capacitors (typically 100 nF) should be placed close to the supply pin. The output is analog and should feed an ADC with adequate resolution (10-bit minimum recommended for the 4.5 V swing to cover 7.25 PSI with ~7 mV/PSI resolution).

MPX5100A - 0 to 115 kPa Absolute Pressure Sensor | NXP
The NXP MPX5100A is an integrated silicon piezoresistive pressure sensor that delivers a calibrated, temperature-compensated analog output from 0.2 V to 4.7 V over an absolute pressure range of 15 kPa to 115 kPa (approximately 2.18 PSI to 16.68 PSI), housed in a 6-SIP through-hole module. Designed for direct connection to a microcontroller or microprocessor A/D input, the sensor integrates a monolithic sensing element with on-chip signal conditioning and bipolar signal processing, eliminating the need for external calibration. An absolute pressure sensor is a transducer that measures pressure referenced to a perfect vacuum rather than to local atmospheric pressure. Absolute pressure sensors (working in the category hierarchy: pressure sensor -> piezoresistive transducer -> MEMS sensor -> sensor IC -> semiconductor) are critical in applications where the measurement must remain unaffected by changes in weather, altitude, or ambient barometric pressure, making them the preferred choice for sealed-system monitoring and barometric reference. Key features include a sensitivity of 45 mV/kPa, a typical full-scale span of 4.5 V across the 0 to 115 kPa operating range, and a temperature-compensated output from 0 C to 85 C. The on-chip ASIC linearizes and calibrates the output, producing a near-rail-to-rail analog signal that interfaces directly with most 5 V ADCs. Power consumption is approximately 10 mA from a single 5 V supply, and the device provides ratiometric output, scaling proportionally with supply voltage. The MPX5100A uses advanced micromachining, thin-film metallization, and bipolar semiconductor processes to combine the mechanical diaphragm and the analog front end on a single die. This patented single-element transducer achieves an accuracy of ±2.5% over the compensated temperature range and provides excellent long-term stability for embedded instrumentation. Typical applications include barometric pressure measurement for weather stations and altimeters, HVAC airflow and duct pressure monitoring, medical respiratory equipment, industrial process control, and automotive manifold absolute pressure (MAP) sensing. The 0.2 V to 4.7 V output is well-suited for direct ADC input without additional signal conditioning. When designing with this part, ensure a stable 5 V supply and place a 100 nF decoupling capacitor close to the supply lead. The sensor requires a port reference for absolute measurements and is sensitive to mechanical stress on the package - mount with minimal torque on lead connections and avoid applying side loads to the sensor body.

MPX5100AP - 0-100kPa Absolute Pressure Sensor, 6-SIP | NXP
The NXP MPX5100AP is a monolithic silicon piezoresistive absolute pressure sensor in a 6-pin SIP module with axial port, integrating on-chip signal conditioning, temperature compensation, and calibration. The device measures absolute pressure from 15 kPa to 115 kPa (approximately 2.18 to 16.68 PSI) with a ratiometric analog output of 0.2 V to 4.7 V across a 5.0 V supply, delivering a usable dynamic range that covers sub-atmospheric barometric, ambient, and mildly elevated pressure conditions in a single transducer. An absolute pressure sensor is a transducer whose output is referenced to a sealed internal vacuum cavity rather than to ambient atmosphere, so it reports true pressure independent of weather or altitude variation. Absolute pressure sensors sit within the broader MEMS (micro-electromechanical systems) sensor family and operate alongside gauge and differential pressure variants. In the MPX5100 family, the 'A' suffix denotes absolute reference while 'D' (differential) and 'G' (gauge) variants address other reference schemes, all sharing the same ASIC core and pinout. Key features include ±2.5% maximum pressure error over 0 °C to +85 °C, 1% full-scale-span temperature compensation, and a noise-immune ratiometric output that tracks VCC to compensate for supply variation in microcontrollers with ADC inputs. The 5.0 V single-supply operation draws approximately 10 mA typical supply current, and the 6-SIP package provides port-style mounting with a 0.19 inch (4.93 mm) tube interface for hose or pneumatic connection. The MPX5100AP uses a patented single-element X-ducer strain-gauge bridge micromachined from silicon and laser-trimmed at wafer level for offset and span calibration. This integrated approach eliminates the need for external compensation networks, op-amps, or trimpots, simplifying firmware development and lowering BOM cost in volume production. Typical applications include barometric pressure measurement for weather stations and altimeters, HVAC air-flow monitoring, medical respirator and ventilator pressure feedback, industrial process pressure trending, and engine manifold absolute pressure (MAP) sensing in non-automotive engine control. The wide 0 °C to +85 °C compensated temperature range also suits outdoor and industrial enclosures. When designing with this device, reserve a 0.1 uF bypass capacitor close to the supply pin and connect the output directly to a microcontrollers ADC with adequate input impedance (typically greater than 50 kΩ) to minimize loading error. For barometric altimetry, average multiple ADC samples to filter mechanical and electrical noise that can otherwise couple into the LSB of the conversion.

MPX5100D - 100 kPa Differential Pressure Sensor | NXP Semiconductors
The NXP Semiconductors MPX5100D is an integrated, on-chip signal-conditioned, temperature-compensated and calibrated piezoresistive silicon pressure sensor with a 0 to 100 kPa (0 to 14.5 PSI) differential pressure range and a 0.2 V to 4.7 V analog ratiometric output, packaged in a 6-lead through-hole SIP module. A piezoresistive pressure sensor is a transducer that converts an applied pressure into a measurable electrical signal by exploiting the piezoresistive effect in silicon; the on-chip signal conditioning, temperature compensation, and factory calibration eliminate the need for external amplification or trimming in most applications. Piezoresistive sensors occupy the middle of the transducer hierarchy, between raw resistive strain gauges and fully integrated MEMS pressure modules that include digital I²C/SPI outputs. The MPX5100 series is widely adopted in cost-sensitive embedded designs that need an analog, microcontroller-friendly signal. Key features include a differential pressure range of 0 to 100 kPa (0 to 14.5 PSI), supply voltage of 4.75 V to 5.25 V, typical full-scale span of 45 mV/kPa, accuracy of ±1.8 %VFSS (maximum), and an operating temperature range of -40 °C to +125 °C. The ratiometric analog output spans 0.2 V at zero pressure to 4.7 V at full-scale pressure, mapping directly into a 0–5 V microcontroller ADC without external op-amps. The monolithic single-element die combines micromachined sensing, thin-film metallization and bipolar processing for long-term stability. Architecturally, the device is a monolithic silicon die in which a micromachined diaphragm and four piezoresistors form a Wheatstone bridge; the bridge is excited by the supply voltage so the output is ratiometric, and on-chip ASIC circuitry offsets, spans, and temperature-compensates the raw signal. The calibrated output swing of 4.5 V across 100 kPa gives a usable sensitivity of 45 mV/kPa and supports direct connection to a 10-bit ADC. The through-hole SIP module includes a dual axial pressure port geometry (P1 = high-pressure side, P2 = low-pressure or vacuum reference) for differential measurement on tube-fed systems. Typical applications include automotive engine manifold absolute pressure (MAP) sensing, barometric air-pressure monitoring, HVAC duct pressure measurement, medical respiratory equipment, and industrial process-control loops. The wide temperature range and ratiometric output make it a drop-in choice for ECU analog-input front-ends. When designing in the MPX5100D, place 100 nF and 470 pF decoupling capacitors close to the supply pin to suppress switching noise from digital logic sharing the same 5 V rail. Tubes on the P1/P2 ports should be kept as short as possible and oriented vertically downward to avoid condensate pooling on the die. Designers targeting board-mounted applications should evaluate the surface-mount 8-pin SOIC option MPXV5100GC6U if a vertical (axial) port orientation is undesirable. This page synthesizes distributor pricing, MPX5100 family cross-reference data and practical design notes not found in the manufacturer datasheet alone, helping engineers compare drop-in equivalents and choose the correct variant for tube-fed differential sensing, MAP-sensing or HVAC pressure-front-end designs.
MPX5100DP - 0-100kPa Differential Pressure Sensor 5V 6-SIP | NXP
The NXP MPX5100DP is a monolithic piezoresistive silicon pressure transducer delivering a calibrated, temperature-compensated analog output proportional to applied differential pressure from 0 to 100 kPa (0 to 14.5 PSI). The MPX5100DP operates from a single 5 V supply and provides a ratiometric 0.2 V to 4.7 V output (approximately 4.5 V span) through on-chip signal conditioning and laser-trimmed thin-film resistors, all housed in a 6-SIP through-hole module with dual 4.93 mm tube ports. A piezoresistive pressure sensor is a MEMS device in which a micromachined silicon diaphragm with embedded strain gauges converts applied pressure into a resistance change, then to a voltage via a Wheatstone bridge. Integrated signal conditioning, temperature compensation, and calibration place the MPX5100DP in the broader sensor hierarchy: pressure transducer -> piezoresistive sensor -> MEMS sensor -> semiconductor IC. This integration allows direct connection to a microcontroller ADC without external analog front-end components. Key features include 5 V single-supply operation, 0.2 V to 4.7 V ratiometric output (4.5 V span), ±2.5% accuracy over 0 to 85 °C, 1 kHz response bandwidth, and built-in temperature compensation from -40 °C to +125 °C. The dual horizontal port configuration (both ports on the same side) enables easy plumbing for differential measurements, while the through-hole 6-SIP package simplifies breadboard prototyping and hand-soldered repair. The transducer combines advanced micromachining, thin-film metallization, and bipolar signal conditioning on a single die. On-chip laser trimming calibrates both span and offset, eliminating the need for external trimpots in production designs. The ratiometric output scales with supply voltage, allowing ADC reads using the 5 V rail as reference for maximum noise immunity and resolution. Typical applications include HVAC air-flow monitoring, industrial process control, respirators and ventilators, altimeters and barometric instruments, medical pump monitoring, and automotive manifold absolute pressure mapping. The wide 0-100 kPa range covers natural atmospheric and moderate positive-pressure industrial environments. When designing with this part, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin and add a 10 µF bulk cap on the supply rail. Use the 5 V supply as the ADC reference voltage to exploit the ratiometric output and minimize absolute supply-noise coupling.

MPX5100GP - 0-100 kPa Gauge Pressure Sensor | NXP
The NXP MPX5100GP is an integrated silicon piezoresistive pressure sensor delivering a 0 to 100 kPa (0 to 14.5 psi) gauge pressure range with on-chip signal conditioning, temperature compensation, and calibration, packaged in a 6-SIP through-hole module with a 0.19" (4.93 mm) tube port. The transducer outputs an analog voltage of 0.2 V to 4.7 V from a 5 V supply, providing an essentially ratiometric signal chain output for direct connection to a microcontroller A/D input. What is a gauge pressure sensor? A gauge pressure sensor measures pressure referenced to ambient atmospheric pressure, in contrast to absolute or differential sensors that reference a sealed vacuum or a second port. Gauge sensors are the most common type used in atmospheric-pressure-relative measurements because the readout is already corrected for local barometric pressure, simplifying downstream calculations. The MPX5100GP belongs to the integrated pressure sensor family, which combines the MEMS sense element and the analog conditioning ASIC in a single monolithic device. Key specifications include an operating pressure range of 0 kPa to 100 kPa, a 5 V nominal supply (with 4.75 V to 5.25 V compliance), a full-scale span of approximately 4.5 V, and an accuracy of about 2.5% over the compensated temperature range. The device draws 7 mA to 10 mA from the supply and offers a response time in the low-millisecond range, making it well suited for real-time control loops where low-latency pressure feedback is required. The MPX5100GP uses NXP's patented single-element piezoresistive transducer combined with bipolar signal-conditioning circuitry on the same die. The on-chip ASIC provides a temperature-compensated, calibrated analog output that is laser-trimmed during production, so the user does not need to perform any external linearization or temperature correction. The integrated signal chain reduces BOM count and PCB area compared to a raw sensor plus external op-amp topology. Typical applications include HVAC duct pressure monitoring, medical respirators and ventilators, industrial pneumatic controls, altimeters and weather instruments, and engine manifold pressure measurement. The wide 0 to 100 kPa range and integrated signal conditioning make the device particularly attractive in microcontroller-based designs that require an analog front-end with minimal external components. When designing with the MPX5100GP, ensure a stable 5 V supply with adequate decoupling close to the supply pin. The output is ratiometric to the supply, so noise or drift on VCC translates directly to the output signal; using a low-noise LDO such as the TPS7A4701 for the analog rail improves measurement repeatability. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including side-by-side comparisons with the MPX5100DP and other MPX-series variants.
MPX5100GSX - 100kPa Vented Gauge Pressure Sensor | NXP
The NXP MPX5100GSX is a 100 kPa integrated silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, packaged in a 6-pin SIP (Case 867G) module with a 0.19 inch (4.93 mm) male tube port. It provides a ratiometric analog output of 0.2 V to 4.7 V proportional to applied pressure from 0 kPa to 100 kPa (0 psi to 14.5 psi gauge), and is designed for direct connection to microcontrollers and microprocessors with A/D inputs. A piezoresistive pressure sensor is a transducer that converts applied mechanical pressure into a measurable electrical signal by exploiting the change in resistance of silicon strain gauges diffused into a diaphragm. The output voltage is ratiometric to the supply (typically 5.0 V), meaning the output scales linearly with Vcc, allowing simple A/D conversion in microcontroller-based systems. The MPX5100 specifically belongs to NXP's integrated sensor family, adding laser-trimmed calibration and active temperature compensation on the same monolithic silicon die - features historically found only in higher-cost instrumentation-grade sensors. Key features of the MPX5100GSX include a pressure range of 0 kPa to 100 kPa (0 psi to 14.5 psi), accuracy of ±2.5% over 0 C to 85 C, sensitivity of 45 mV/kPa (typical), and a supply voltage range of 4.75 V to 5.25 V. The on-chip instrumentation amplifier delivers a low-impedance ratiometric output with high noise immunity, while the vented gauge reference compensates for ambient atmospheric pressure drift in real time. The silicon diaphragm is micromachined using NXP's proprietary process, with strain gauges arranged in a Wheatstone bridge on the diaphragm surface. Application of pressure deflects the diaphragm, unbalancing the bridge and producing a differential voltage proportional to pressure. The on-chip ASIC converts this differential millivolt signal into a 0.2 V to 4.7 V output through a precision chopper-stabilized amplifier, providing excellent long-term stability and EMI rejection. Typical applications include HVAC blower pressure monitoring, medical respirators and ventilators, industrial process control, altimeters and barometric instruments, and automotive manifold pressure sensing. The rugged ported SIP housing is suitable for manifold mounting via O-ring seal in pneumatic systems. The MPX5100GSX is part of NXP's legacy MPX5100 series. NXP recommends a 47 nF decoupling capacitor between Vcc and GND placed as close as possible to the sensor pins. The vent tube must remain unblocked and protected from moisture to maintain accurate gauge reference.

MPX53D - 50kPa Differential Uncompensated Pressure Sensor | NXP
The NXP MPX53D is a 0-50 kPa differential, uncompensated, silicon piezoresistive pressure sensor housed in a 4-SIP unibody package. It delivers a linear analog voltage output of 0 mV to 60 mV at 3 V supply directly proportional to applied pressure, with a full-scale operating pressure of 7.25 PSI (50 kPa). The MPX53D is part of the legacy MPX53 family originally introduced by Freescale Semiconductor and now served by both NXP and STMicroelectronics. The sensor uses a single piezoresistive strain gauge diffused into a silicon diaphragm, which deflects under differential pressure and produces a Wheatstone-bridge output that requires external temperature compensation and signal conditioning. A pressure sensor is a transducer that converts an applied pressure into a measurable electrical signal. Uncompensated sensors like the MPX53D output a raw millivolt signal that is highly linear with pressure but drifts with temperature; therefore, designers typically add external op-amp-based offset, span, and temperature-compensation networks. Compensated versions (e.g., MPX5700 series) place those networks on-chip at higher cost. The MPX53D's unibody package and through-hole 4-SIP form factor target cost-sensitive designs where the engineer is willing to design their own analog front end. Key features include a differential port style (two parallel pressure ports on the same side of the package), a 3 V typical supply voltage, 60 mV full-scale output at 3 V, and a robust unibody construction rated for media compatible with the silicon/stainless-steel interface (see ST application note AN3728). The device's port geometry accepts standard 3.45 mm (0.136 in) pressure tubing, and its PCB-through-hole mounting simplifies prototyping. Typical applications include low-cost HVAC pressure monitoring, air-flow sensing in instrumentation, altimeters, barometric compensation, and disposable medical pressure devices where cost dominates accuracy. Its small differential range also suits process-control loops measuring filter pressure drop. Designers should plan for external temperature-compensation op-amps (e.g., a single-supply quad op-amp) and a low-offset, low-noise instrumentation amplifier to extract full dynamic range. Add a protection resistor and TVS clamp at the sensor pins if the media can include liquid condensation spikes. This page synthesizes verified distributor pricing, drop-in same-package alternatives from NXP and STMicroelectronics, and practical design notes that complement the manufacturer datasheet.
MPX53DP - 50 kPa Uncompensated Differential Pressure Sensor | NXP
The NXP MPX53DP is a 50 kPa uncompensated silicon piezoresistive pressure sensor housed in a 4-SIP through-hole module with a dual vertical port configuration. It delivers a linear differential voltage output from 0 mV to 60 mV at a 3 V supply, directly proportional to applied pressure across the 0 to 50 kPa (0 to 7.25 PSI) range. The device targets cost-sensitive applications where designers add their own external temperature compensation and signal conditioning. A piezoresistive pressure sensor is a MEMS device in which diffused silicon strain gauges form a Wheatstone bridge on a diaphragm; differential pressure on the two ports flexes the diaphragm and unbalances the bridge to produce a millivolt-level output. Uncompensated sensors, like the MPX53DP, ship without internal calibration networks, giving designers full control over bandwidth, filtering, and temperature correction. Within the sensor hierarchy, the MPX53DP belongs to the uncompensated pressure sensor family, sitting below amplified/calibrated parts in price but above raw strain gauges in usability. Key features of the MPX53DP include a typical full-scale output of 60 mV at 3 V excitation, a sensing accuracy of approximately 0.4% linearity, dual through-hole pressure ports for differential measurement, and an operating temperature range of -40C to +125C. The 4-SIP package provides port isolation between the high and low pressure sides while keeping the die mechanically decoupled from the PCB stress. The dual-port layout simplifies plumbing in flow and differential-pressure designs. The MPX53/MPXV53GC series uses a single-element silicon die with a four-resistor piezoresistive bridge diffused onto a chemically-etched diaphragm. Pressure across the two ports generates diaphragm deflection, which alters the bridge balance and produces the differential output. Because the sensor is uncompensated, designers must implement an instrumentation amplifier (e.g., NXP MPX2010DP-compatible front end) plus temperature compensation in firmware or with a thermistor network to achieve tight span and offset accuracy across temperature. Typical applications include medical respirators and ventilators, HVAC differential pressure switches, altitude meters, industrial process control, and liquid-level flow measurement. The differential port configuration makes the MPX53DP especially well-suited to measuring pressure drop across orifice plates, filters, or heat exchangers. The dual-port topology is also commonly used in low-cost airflow and water-flow metering. A key design consideration is the mandatory external signal conditioning: any subsequent amplifier must have low offset drift (under 5 uV/C) to preserve the sensor's intrinsic linearity, and the excitation voltage must be tightly regulated because output is ratiometric to VSUPPLY. For portable battery-powered designs, designers often use a chopper-stabilized op-amp to keep quiescent power under 1 mA while still achieving 12-bit effective resolution after calibration. This page synthesizes distributor pricing, drop-in and same-package MPX53 alternatives, and practical design notes not found in the manufacturer datasheet alone.
MPX53GP - 50 kPa Uncompensated Gauge Pressure Sensor | NXP
The NXP MPX53GP is a 50 kPa uncompensated piezoresistive silicon pressure sensor in a 4-SIP through-hole module with a vented-gauge barbed tube port. It delivers a linear differential analog output of 0 mV to 60 mV at 3 V supply, directly proportional to applied gauge pressure over a 0 to 50 kPa (0 to 7.25 PSI) range, with a maximum overpressure rating of 175 kPa (25.38 PSI). A piezoresistive pressure sensor is a MEMS device in which a silicon diaphragm with embedded Wheatstone-bridge resistors deflects under pressure, unbalancing the bridge and producing a millivolt-level differential output. As an uncompensated sensor, it sits in the same broad hierarchy as compensated pressure sensors, altimeters, and barometric ICs; users must add their own external temperature-compensation and signal-conditioning networks to achieve the accuracy levels required for their end system. Key features include a ±0.6% to ±0.4% accuracy window, a vented-gauge reference for direct absolute-pressure readout in barometric systems, a 4.93 mm barbed male port for flexible-tube pneumatic interfaces, and the wide 0 to 175 kPa proof-pressure range that protects against pressure spikes in fluid and pneumatic systems. The 4-SIP vertical package enables simple through-hole PCB assembly and easy integration into a system front-end alongside an instrumentation amplifier. Typical applications include medical respiratory monitors (ventilators, CPAP, spirometers), industrial pneumatic controllers, HVAC pressure monitors, altimeters and barometric instruments, and consumer weather stations, where the uncompensated wheatstone-bridge output stage feeds directly into a low-noise op-amp such as an MCP6001 or instrumentation amplifier. When designing with the MPX53GP, the engineer must add an external instrumentation amplifier and temperature-compensation network; the bare 60 mV full-scale output at 3 V is too small and too temperature-dependent for direct ADC input. Use the front-end reference voltages and supply decoupling shown in the manufacturer application note for repeatable thermal drift performance. This page consolidates distributor pricing, drop-in pin-compatible alternatives, and practical design guidance not found in the bare manufacturer datasheet, accelerating MPX53GP selection for new designs.
MPX5500D - 500 kPa Differential Pressure Sensor | NXP
The NXP MPX5500D is a 500 kPa differential piezoresistive silicon pressure sensor with on-chip signal conditioning and temperature compensation, housed in a 6-pin SIP (Single In-line Package) module. It provides an analog output of 0.2 V to 4.7 V ratiometric to a 5 V supply, corresponding to 0 kPa to 500 kPa differential pressure across its two ports. An integrated silicon pressure sensor is a monolithic semiconductor device in which a micromachined diaphragm deflects under applied pressure, changing embedded piezoresistive elements in a Wheatstone bridge. The MPX5500D belongs to the pressure sensor hierarchy: pressure transducer -> pressure sensor -> sensor IC -> signal conditioning IC -> semiconductor. Compared to resistive or ceramic capacitive sensors, monolithic silicon pressure sensors integrate amplification, calibration, and temperature compensation on the same die, eliminating external compensation circuitry and delivering near-direct ADC compatibility for microcontrollers. Key features of the MPX5500D include a 0.2 V to 4.7 V analog output (0.5 V to 4.5 V typical usable span), 9 mV/kPa nominal sensitivity, 1 ms response time, ±1.5% accuracy over 0°C to 85°C, and ratiometric output operation from a single 4.75 V to 5.25 V supply. The on-chip ASIC performs laser-trimmed offset and span calibration, ensuring part-to-part interchangeability without external trim potentiometers. The device is also EMC-protected and qualified to typical industrial pressure-sensor environmental standards. Typical applications include industrial process control, HVAC blower monitoring, water pressure monitoring, gas metering, and pneumatic system feedback in factory automation. Its differential (not gauge or absolute) reference makes it well-suited to measuring pressure drop across orifices, filters, or pumps in flow-derived systems. The 5 V ratiometric output connects directly to the ADC input of 5 V microcontrollers. When designing with this device, decouple the Vs pin with a 100 nF ceramic capacitor placed within 5 mm of the lead. Apply pressure only via the silicone gel-protected side ports to avoid damaging the diaphragm, and avoid PCB stress on the SIP body that could couple mechanical strain into the sensor element.
