MPXAZ4100A6U - 20-105 kPa Absolute Pressure Sensor | NXP
The NXP Semiconductors MPXAZ4100A6U is an integrated silicon piezoresistive pressure sensor for manifold absolute pressure (MAP) applications, providing an analog output of 0.3 V to 4.9 V proportional to applied pressure over a 20 kPa to 105 kPa (2.9 PSI to 15.23 PSI) absolute range, housed in an 8-SMD gull-wing surface-mount module. A board-mount pressure sensor (also called a pressure transducer or MAP sensor) is a hermetically sealed micro-electromechanical (MEMS) device that converts applied pressure into a calibrated analog voltage. Within the broader sensor taxonomy, absolute pressure sensors sit alongside gauge and differential sensors, and they belong to the larger family of silicon MEMS transducers. The MPXAZ4100A series belongs to the signal-conditioned, temperature-compensated, and factory-calibrated subfamily, removing the need for external amplification or trimming in typical automotive intake-manifold designs. Key features include on-chip signal conditioning, temperature compensation over -40 °C to +125 °C, and ratiometric analog output that tracks the supply rail, making the output immune to 5 V supply noise. The single 4.85 V to 5.35 V supply, 8-SMD gull-wing leadless package, and absolute pressure port support through-hole reflow assembly while maintaining a small PCB footprint, in line with modern engine-control-unit (ECU) design rules. Output is factory calibrated to 4.9 V at 105 kPa and 0.3 V at 20 kPa with a typical full-scale accuracy within ±1.8 %VFSS. The MPXAZ4100A6U combines bipolar semiconductor processing with thin-film metallization and advanced micromachining to integrate the strain-gauge bridge, temperature compensation, and calibration network onto a single die. Its ratiometric output rejects power-supply variation, and the integrated port geometry resists common automotive media including fuel vapors and contaminated intake air. Compared with discrete bare-die pressure sensors, it removes board-level signal chain design work and reduces ECU BOM count. Typical applications include automotive engine control (MAP sensing), HVAC pressure monitoring, barometric correction in GPS/navigation modules, weather stations, industrial pneumatic monitoring, and altitude estimation in drones and handheld instruments. The wide 5 V supply and calibrated ratiometric output allow direct ADC interfacing without external signal conditioning. When designing with this part, place a 0.01 µF ceramic decoupling capacitor as close to the supply pin as possible and avoid sharp PCB bends in the manifold pressure port to minimize turbulence. The sensor output is ratiometric, so the ADC reference must be tied to the same 5 V rail as VCC for best absolute accuracy; otherwise supply ripple translates directly into pressure-reading error.

MPXAZ4100AC6U - 20-105kPa Absolute Pressure Sensor | NXP
The NXP MPXAZ4100AC6U is an integrated silicon piezoresistive pressure sensor covering 20 kPa to 105 kPa (2.9 PSI to 15.23 PSI) absolute pressure, housed in an 8-SMD gull-wing top-port package with on-chip signal conditioning, temperature compensation and calibration. The device produces a ratiometric analog output of 0.3 V to 4.9 V proportional to absolute pressure, supplied from a single 4.85 V to 5.35 V rail, and is qualified for automotive manifold absolute pressure (MAP) sensing. An absolute pressure sensor measures pressure referenced to a sealed vacuum rather than to ambient atmosphere, distinguishing it from gauge or differential sensors. The MPXAZ4100A series belongs to the broader transducer family, which converts physical quantities (pressure, temperature, acceleration) into electrical signals. Absolute pressure sensors are essential wherever a known vacuum reference is required - most prominently in engine control units where manifold pressure directly correlates with air mass and load. The MPXAZ4100AC6U integrates a single-chip MEMS piezoresistive bridge plus a custom ASIC that performs offset, span and temperature compensation. Media-resistant gel protects the die from harsh automotive intake environments, while the top-port 1/8" (3.17 mm) tube inlet accepts a vertical hose attachment typical of MAP installations. The ratiometric analog output simplifies ADC sampling with the same 5 V reference used by most engine ECUs. Typical applications include automotive engine manifold absolute pressure (MAP) sensing, barometric pressure correction, HVAC pressure monitoring, and industrial pneumatic control. Its 0-85 °C compensated range with extended survivability to 125 °C allows under-hood placement. Designers should route the analog output through an RC low-pass filter before ADC sampling to reject EMC events typical in automotive environments. Use a 100 nF decoupling capacitor close to the supply pin and ensure the hose inlet is oriented vertically to prevent condensate pooling that could damage the gel-protected die.

MPXAZ4115A6T1 - 15-115kPa Absolute Pressure Sensor | NXP | SMT-8
The NXP (formerly Freescale) MPXAZ4115A6T1 is a media-resistant, integrated silicon absolute pressure sensor in an 8-pin SMD (Gull Wing) module, delivering a calibrated analog output of 0.2 V to 4.8 V over a pressure range of 15 kPa to 115 kPa (2.18 PSI to 16.68 PSI). It integrates on-chip bipolar op-amp signal conditioning and a thin-film resistor network to provide temperature compensation from -40C to +125C, suitable for manifold absolute pressure (MAP) sensing, altimeter, and barometer applications. A pressure sensor is a transducer that converts applied pressure into an electrical signal proportional to force per unit area. In the pneumatic hierarchy, pressure sensors sit alongside temperature, flow, and humidity sensors as primary environmental measurement devices. Absolute (or "sealed-reference") sensors measure pressure relative to a sealed vacuum reference built into the die, rather than against ambient atmospheric pressure, which makes them ideal for sealed systems such as manifold pressure sampling and weather-station barometers. Key features include a supply range of 4.85 V to 5.35 V (5.0 V nominal), low power consumption suited for battery-powered systems, and integrated signal conditioning that removes the need for external op-amps, calibration registers, or compensation look-up tables. The output is ratiometric to the supply voltage, which simplifies ADC interfacing by allowing an MCU ADC reference tied directly to the same 5 V rail. The architecture combines a piezoresistive strain-gauge bridge (forming a Wheatstone bridge on the silicon diaphragm) with an on-die bipolar op-amp stage and thin-film laser-trimmed compensation resistors. The Sifel 827 gel isolation layer protects the silicon die from harsh media such as refrigerants, fuel vapor, and humid intake air, while still transmitting pressure through to the diaphragm with negligible hysteresis. Typical applications include automotive engine control units (MAP sensors), HVAC pressure monitoring, weather stations and altimeters, medical respiratory equipment, and industrial pneumatic system monitoring. Designers choose this part because the integrated compensation eliminates firmware-side linearization across the industrial -40C to +125C range. When designing with the MPXAZ4115A6T1, plan for a 10 kHz or lower input bandwidth on the downstream ADC to reject sensor thermal noise; the device output bandwidth exceeds most MCU ADCs and averaging is recommended. Mount the sensor port away from PCB thermal hotspots, because the Sifel gel introduces a small thermal-conductivity drift visible at high dT/dt.

The device operates from a single 4.85 V to 5.35 V supply and is housed in an 8-SMD gull-wing module designed for surface-mount reflow assembly. An absolute pressure sensor measures pressure referenced to a sealed internal vacuum, making it ideal for applications where barometric or altitude-corrected readings are required. Absolute pressure sensors sit in the transducer family beneath the wider category of pressure sensors and transducers, enabling direct ADC interfacing without bridge excitation amplifiers. Key features include on-chip signal conditioning, factory temperature compensation from 0C to +85C, and a media-resistant port that tolerates humid and mildly contaminated air. The transfer function is approximately linear at 46.4 mV/kPa, allowing straightforward conversion from output voltage to pressure. Integrated bipolar op-amp and thin-film resistor networks eliminate external compensation components and reduce PCB footprint compared to discrete bridge sensor designs. The device integrates a single piezoresistive bridge, an instrumentation amplifier, a temperature compensation network, and a calibration trim network on the same silicon die. Calibration is performed during manufacturing, yielding typical accuracy better than +/-1.5% over the compensated temperature range, which is sufficient for altimeter, barometer, weather station, and industrial manifold absolute pressure (MAP) applications without user-side calibration. Typical applications include automotive manifold absolute pressure sensing, handheld altimeters and barometric altimetry, GPS-augmented navigation altitude correction, weather stations and HVAC control, and portable medical pneumatic devices. The wide 15-115 kPa span covers sea-level barometric pressure (~101.325 kPa) up to altitudes above 9000 m with margin. When designing with this part, place 100 nF and 470 pF decoupling capacitors as close to VCC and GND pins as possible to reject supply noise. Avoid exposing the port to direct water jets or condensing humidity beyond the media-resistant specification. For high-accuracy altimeter designs, apply per-unit calibration lookup tables in software to compensate residual non-linearity. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes that complement the NXP datasheet and accelerate time-to-design for absolute-pressure instrumentation.
MPXAZ4115AC6U - 15-115kPa Absolute Pressure Sensor | NXP
The NXP MPXAZ4115AC6U is a media-resistant, integrated silicon piezoresistive absolute pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, housed in an 8-SMD gull-wing top-port package (CASE 482A). It measures absolute pressure from 2.18 PSI to 16.68 PSI (15 kPa to 115 kPa) and outputs an analog voltage from 0.2 V to 4.8 V proportional to the applied pressure, suitable for manifold absolute pressure, altimeter, and barometer applications. A pressure sensor is a transducer that converts an applied mechanical pressure into a proportional electrical signal. Absolute pressure sensors reference a sealed internal vacuum cavity, so the output corresponds to pressure relative to absolute zero rather than to ambient atmospheric pressure. Within the broader sensor taxonomy, this device sits in the piezoresistive family, where silicon strain gauges arranged in a Wheatstone bridge change resistance with membrane deflection. NXP's MPXAZ series adds on-chip thin-film calibration resistors, temperature compensation, and a signal-conditioning amplifier, producing a ratiometric analog output that interfaces directly with an ADC, microcontroller, or analog comparator. Key differentiating features include a calibrated accuracy of approximately ±1.5% across the full pressure range, operating temperature coverage from -40°C to +125°C, a supply voltage range of 4.85 V to 5.35 V, and a top-side male port with a 3.17 mm (0.13 in) tube stub that accepts media-resistant tubing. The 8-SMD gull-wing package supports surface-mount assembly and reflow soldering, while the integrated calibration eliminates external compensation components. The output stage is ratiometric to VCC, simplifying ADC scaling in 5 V microcontroller systems. Internally, the MPXAZ4115AC6U uses a single-crystal silicon diaphragm with diffused piezoresistors whose resistance changes with strain. The on-chip CMOS signal conditioner performs offset trim, span calibration, and temperature compensation using laser-trimmed thin-film resistors, yielding a factory-calibrated transfer function that requires no external components other than decoupling capacitors. The top port design places the pressure inlet on the package top, which simplifies pneumatic connection and protects the sensing element from board-side contamination. Typical applications include automotive manifold absolute pressure (MAP) sensing, motorcycle and small-engine fuel management, altimeters and barometric reference systems, weather stations and indoor pressure monitors, HVAC pressure monitoring, and industrial process control. In automotive MAP applications, the wide temperature range and media-resistant port allow direct pneumatic connection to the intake manifold. When designing with this part, ensure the supply voltage stays within 4.85 V to 5.35 V and provide at least 100 nF of supply decoupling adjacent to the device. The output is ratiometric to VCC, so a stable 5 V rail is essential for accurate readings. Avoid exposing the port to condensing moisture or conductive contaminants unless the media-resistant tubing variant is used.

A pressure sensor transducer is a device that generates an electronic signal as a function of applied pressure. The MPXAZ6115A6U sits within the integrated silicon pressure sensor category, a sub-family of MEMS (micro-electromechanical systems) sensors that combine a piezoresistive sensing element with on-chip signal conditioning. These devices sit in the broader hierarchy of sensors -> pressure sensors -> absolute pressure sensors -> MEMS sensors -> semiconductor devices. By integrating the bipolar op-amp circuitry and thin-film resistor networks on a single die, NXP delivers a fully calibrated, temperature-compensated analog voltage output that engineers can feed directly into an ADC, eliminating discrete amplifier stages. The MPXAZ6115A6U integrates on-chip bipolar operational amplifier circuitry and thin-film resistor networks to deliver a high-level output signal with built-in temperature compensation and calibration. According to the NXP datasheet, the device achieves ±1.5% accuracy over the operating range, supports an absolute pressure range of 15 kPa to 115 kPa, and tolerates maximum overpressure up to 400 kPa (58.02 PSI). The 0.2 V to 4.7 V analog output is ratiometric to a 5 V supply, simplifying ADC interface design. Key differentiating features of this part versus a bare piezoresistive die include the integrated signal conditioning, automotive-grade media resistance (the 'Z' suffix indicates media-resistant gel coating), and the calibrated, temperature-compensated output. The 'A6' package variant denotes the surface-mount 8-pin SMD module form factor with axial port orientation suited for manifold reference applications. The MPXAZ6115A6U is part of NXP's MPXxx6115A series and shares its core die technology with the related MPXA6115A6U variant.

The 15-115 kPa range covers full atmospheric pressure (101.325 kPa) plus boost pressures typical in turbocharged and naturally-aspirated engine intake manifolds. When designing with this part, ensure the ADC reference voltage tracks the 5 V sensor supply to preserve ratiometric accuracy, and add an RC low-pass filter on the output to attenuate sensor noise. The gel-protected media-resistant coating must not be mechanically damaged during PCB assembly; conformal coating on the host board should avoid the sensor port.

MPXAZ6115A7U - 15-115 kPa Absolute Pressure Sensor | NXP
The NXP MPXAZ6115A7U is an absolute pressure sensor with an operating range of 15 to 115 kPa (2.18 to 16.68 PSI), housed in an 8-DIP through-hole module with a top-side axial tube port. It provides an analog ratiometric output from 0.2 V to 4.7 V proportional to applied absolute pressure, with on-chip signal conditioning, temperature compensation, and factory calibration. An absolute pressure sensor is a transducer that measures pressure referenced to a perfect vacuum rather than ambient atmosphere. Absolute pressure sensors integrate on-chip bipolar op-amp signal conditioning and thin-film resistor networks, producing a high-level linear analog output. Pressure sensors belong to the sensor hierarchy: pressure transducer > absolute pressure sensor > MEMS pressure sensor > integrated silicon pressure sensor > semiconductor IC. They are commonly used in applications where accurate absolute pressure (barometric or sealed system) is required rather than gauge pressure. Key features include a pressure range of 15 to 115 kPa, an output span of approximately 4.5 V across the full range, and typical sensitivity of about 45.9 mV/kPa. The on-chip temperature compensation delivers ±1.5% accuracy over 0C to +85C. The device operates from a single 5 V supply (typical) and provides an ratiometric output that tracks the supply voltage. Media-resistant construction tolerates non-corrosive gases and dry air. The MPXAZ6115A7U uses NXP's proprietary piezoresistive MEMS sensing element combined with bipolar op-amp signal conditioning on a single silicon die. This monolithic integration eliminates external compensation components and delivers a calibrated, linear output ready for direct ADC input. The X-ducer top-port package routes media to the top of the die through a 0.13" (3.17 mm) axial tube port. Typical applications include barometric pressure measurement for weather stations and altimeters, HVAC pressure monitoring, medical respiratory equipment, tire pressure monitoring, and industrial process control. The wide 100 kPa operating span suits atmospheric-pressure sensing at altitudes from below sea level to high-altitude applications. When designing with this sensor, use a low-impedance buffer (such as a 10 kOhm or smaller op-amp follower) between the sensor output and the ADC input to drive ADC sample capacitors without loading the output stage. A 100 nF decoupling capacitor placed close to the VCC pin is recommended. For battery-powered applications, the sensor can be powered only during sampling to minimize average supply current.

MPXAZ6115AC6T1 - 15-115 kPa Absolute Pressure Sensor | STMicroelectronics
The STMicroelectronics MPXAZ6115AC6T1 is a monolithic, signal-conditioned silicon absolute pressure sensor that measures 15 kPa to 115 kPa (2.18 to 16.68 PSI) and delivers an analog 0.2 V to 4.7 V output from a single 4.75 V to 5.25 V supply. The part is housed in an 8-SMD, gull-wing, top-port surface-mount package, making it suitable for PCB-mount designs in space-constrained applications. An absolute pressure sensor is a transducer that outputs a voltage proportional to pressure referenced to a sealed internal vacuum rather than ambient atmosphere. Within the broader taxonomy, the MPXAZ6115AC6T1 is a MEMS (micro-electro-mechanical systems) sensor, then a piezoresistive silicon pressure transducer, then a board-mount pressure sensor family, and finally a power-management-adjacent signal-conditioning device. This category of part is essential wherever a clean, temperature-compensated analog pressure signal must be derived directly from a microcontroller ADC without external amplification. Key features include on-chip bipolar op-amp circuitry and thin-film resistor networks for temperature compensation, an integrated single-port pressure inlet for tube attachment, and a calibrated ratiometric analog output that simplifies ADC sampling from a 5 V supply. The MPXAZ6115AC6T1 also provides media-resistant packaging suitable for non-corrosive dry-gas applications. The on-chip signal conditioning removes the need for external instrumentation amplifiers, which reduces BOM cost and PCB area in cost-sensitive designs. The MPXAZ6115AC6T1 uses advanced micromachining to combine a piezoresistive strain-gauge bridge with bipolar op-amp signal conditioning and laser-trimmed thin-film compensation resistors. According to the manufacturer datasheet, the device provides a near-linear transfer function across its full pressure range with minimal temperature drift over the rated operating range. The integrated vacuum reference (absolute mode) ensures stable readings regardless of barometric pressure changes. Typical applications include automotive manifold absolute pressure (MAP) sensing, HVAC pressure monitoring, weather-station barometric measurement, altimeter reference designs, and industrial pneumatic system monitoring. The integrated compensation makes it particularly well-suited to drop-in designs where calibrated performance is required without a lengthy development cycle. When designing with this device, ensure that the supply voltage stays within 4.75 V to 5.25 V for specified accuracy and that the output load impedance remains high enough to avoid loading the internal op-amp buffer. Tube fitting should be limited to dry, non-corrosive media because the port is not rated for liquid or aggressive chemicals.

MPXAZ6115AC6U - 15-115kPa Absolute Pressure Sensor | NXP
The NXP MPXAZ6115AC6U is a high-temperature accuracy integrated silicon pressure sensor for measuring absolute pressure from 15 kPa to 115 kPa, delivering a calibrated analog voltage output of 0.2 V to 4.7 V in an 8-SMD gull-wing top-port surface-mount package. A pressure sensor, also known as a pressure transducer, is a device that converts an applied pressure into an electrical signal. Absolute pressure sensors measure pressure relative to a sealed vacuum reference rather than ambient air. The MPXAZ6115AC6U belongs to the integrated silicon pressure sensor category (piezoresistive transducer -> MEMS pressure sensor -> pressure sensor -> sensor IC), which integrates the sensing element, signal conditioning, temperature compensation, and calibration on a single silicon die. These devices sit at the front of any pressure-measurement signal chain, feeding an ADC, microcontroller, or display driver. Key differentiating features include on-chip bipolar op-amp signal conditioning, thin-film resistor networks for temperature compensation from -40C to +125C, and ratiometric analog output that scales with supply voltage (typically 5.0 V). The top-port tube mounting allows direct attachment to a manifold or sealed chamber via a 0.13" (3.17 mm) tube. Media-resistant packaging protects the silicon die from harsh gases and liquids, and the 8-SMD gull-wing form factor supports automated pick-and-place assembly. Architecturally, the device uses a piezoresistive Wheatstone bridge micromachined into a silicon diaphragm. As pressure deflects the diaphragm, the bridge resistors change value proportionally, producing a differential output that the on-chip amplifier converts to a single-ended 0.2-4.7 V signal. Internal thin-film trim networks compensate temperature-induced drift across the full automotive operating range. Typical applications include automotive manifold absolute pressure (MAP) sensing, barometric altitude tracking, weather stations, HVAC pressure monitoring, and industrial process control. The 15 kPa lower bound (roughly -0.7 psi) makes it ideal for partial vacuum measurements down to high altitude (above 18,000 ft). When designing with this sensor, always use a clean, regulated 5 V supply and decouple the supply pin with a 100 nF ceramic capacitor placed within 5 mm of the device. Ratiometric ADC sampling (using the same 5 V as the ADC reference) cancels supply-noise errors. Avoid exposing the top-port inlet to condensing moisture or particulates above 5 microns.

MPXAZ6115AP - 15-115 kPa Absolute Pressure Sensor, Side Port | NXP
The NXP MPXAZ6115AP is a monolithic, signal-conditioned silicon piezoresistive absolute pressure sensor covering 15 kPa to 115 kPa (2.18 PSI to 16.68 PSI), housed in an 8-pin SOP (Case 98ASB14767) surface-mount package with a side-mounted tube port and 0.2 V to 4.7 V ratiometric analog output. The on-chip bipolar op-amp circuitry and thin-film resistor networks provide temperature compensation from -40 C to +125 C, plus calibration that yields a typical accuracy of +/-1.5% over the compensated range. A pressure sensor is a transducer that converts an applied pneumatic or hydraulic pressure into a proportional electrical signal. In the broader system taxonomy it sits at the sensing layer: physical stimulus -> transducer -> signal conditioning -> ADC/MCU -> display or control bus. Absolute pressure sensors specifically measure pressure referenced to a sealed vacuum cavity rather than ambient atmosphere, making them the correct topology for barometric altitude, sealed-cavity pressure, and vacuum-relative measurements. Key features of the MPXAZ6115AP include a 5 V nominal supply (4.75 V to 5.25 V), 0.2 V to 4.7 V near-ratiometric output swing, on-chip temperature compensation, +/-1.5% accuracy, and a media-resistant PPS thermoplastic package qualified for harsh-environment mounting. The integrated op-amp front-end eliminates the external instrumentation amplifier that discrete bridge sensors require, reducing BOM cost and PCB area. Technically, the device uses a monolithic silicon strain-gauge bridge diffused into a diaphragm that deflects proportionally to applied pressure. The thin-film laser-trimmed resistor network compensates span, offset, and thermal drift across -40 C to +125 C, producing an output that designers can route directly to an ADC without further analog conditioning. Typical applications include barometric altimeters and weather stations, HVAC pressure monitoring, industrial process control, sealed-cavity leak detection, avionics altitude reference, and medical respiratory instrumentation. The side-port tube geometry suits vertical-mount manifolds and wall-mounted enclosures where a horizontal port would not align with the pressure inlet. When designing with this part, place a 100 nF decoupling capacitor close to VCC and route the analog output trace away from switching nodes to preserve the 1.5% accuracy budget. Confirm that the side-port tube dimensions (0.13 in / 3.17 mm OD) match the system manifold interface, and add a silicone-gasket seal if the media contains moisture or particulates. This page consolidates distributor pricing, drop-in package-compatible alternatives, and application-specific design guidance that complements (but does not duplicate) the manufacturer datasheet.
MPXAZ6115APT1 - 15-115kPa Absolute Pressure Sensor | NXP
The NXP MPXAZ6115APT1 is an integrated silicon pressure sensor that measures absolute pressure from 15 kPa to 115 kPa (2.18 PSI to 16.68 PSI) and provides a temperature-compensated analog output of 0.2 V to 4.7 V from a single 5 V supply. Housed in an 8-pin SMD gull-wing package with a side-mounted male tube port (0.13 inch / 3.17 mm), the device combines a piezo-resistive strain-gauge bridge, on-chip signal conditioning, calibration, and temperature compensation in one molded media-resistant module. An integrated absolute pressure sensor is a transducer that converts applied pressure into a linear analog voltage proportional to the difference between the sensed pressure and a sealed internal vacuum reference. Unlike gauge sensors that vent to atmosphere, absolute sensors embed a fixed vacuum cavity so the output reflects total pressure at the port. In the broader sensor hierarchy, this device sits at the intersection of MEMS transducers and analog signal-chain components, providing a calibrated interface between physical media and downstream ADCs, microcontrollers, or displays without requiring external compensation circuitry. Key features include a 4.7 V full-scale output (typical 4.5 V nominal, maximum 4.8 V per device characterization), on-chip temperature compensation from -40 C to +125 C, media-resistant port construction suitable for non-corrosive gases, and an accuracy band adequate for consumer and industrial barometric applications. The 5 V single-supply operation simplifies interface to 5 V ADCs and standard MCU analog front-ends. The trimmed offset and span calibrations eliminate the need for external potentiometers in most designs. The device uses a patented silicon strain-gauge MEMS bridge coupled to a bipolar signal-conditioning ASIC. The bridge output is amplified, offset-trimmed, span-normalized, and temperature-compensated entirely on-chip, which removes the long calibration procedure typical of raw die pressure sensors. The SMD gull-wing package isolates the sensing die from PCB stress and provides repeatable thermal contact with the surrounding package mass. Typical applications include altimeters and barometric pressure measurement in portable GPS, weather stations, HVAC control loops, tire-pressure monitoring accessories, and industrial pneumatic system monitoring. The absolute reference makes it well-suited to altitude computation, where atmospheric pressure at sea level serves as the anchor. When designing with the MPXAZ6115APT1, place the device away from PCB flex points and avoid mechanical stress on the side port to preserve calibration accuracy. Add a small RC filter at the output to attenuate EMI in industrial installations, and provide adequate clearance around the port for tubing attachments.

MPXC2011DT1 - 10kPa Differential Pressure Sensor 4-SSIP | NXP
The NXP MPXC2011DT1 is a differential piezoresistive pressure sensor rated for 0 to 10 kPa (1.45 PSI) full-scale span in a 4-SSIP side-port Chip Pak module. It delivers a nominal 25 mV full-scale output (typical 2.5 mV/kPa sensitivity) at 10 V excitation and is temperature-compensated over 0 °C to 85 °C. A pressure sensor is a transducer that converts an applied pneumatic or hydraulic force into an electrical signal, and the differential subclass measures the pressure difference between two ports rather than against atmosphere. The MPXC2011DT1 sits in the broader hierarchy of MEMS sensors > pressure sensors > piezoresistive differential sensors > low-pressure signal-chain ICs, commonly paired with instrumentation amplifiers in medical, HVAC, and analytical-instrument front ends. Key features include on-chip temperature compensation and calibration, a piezoresistive Wheatstone-bridge strain gauge fabricated on a silicon diaphragm, a 4-SSIP single inline through-hole module with an integrated side-port pressure inlet, and 0 to 10 kPa operating range matched to respiratory and air-flow measurement applications. The 4-SSIP Chip Pak provides a small 7.6 mm x 12.8 mm footprint with barbed side-port hose connection. The device uses Freescale/NXP's piezoresistive silicon technology in which four ion-implanted resistors arranged in a Wheatstone bridge change resistance proportionally to diaphragm strain. The bridge is laser-trimmed during manufacture so that span, offset, and temperature coefficient are calibrated, allowing direct interface to a low-noise differential amplifier without per-unit compensation. Typical applications include medical respiratory monitoring (spirometry, ventilators), HVAC variable-air-volume boxes, industrial process control, analytical instruments, and portable low-pressure measurement. The differential configuration makes it particularly suitable for flow sensing across orifice plates, where the pressure drop is on the order of a few kPa. When designing with this device, plan for amplification because the 25 mV full-scale output is too small for direct ADC connection - typically a fixed-gain instrumentation amplifier with a gain of 40 to 160 is placed immediately after the sensor. The sensor output is ratiometric to the excitation voltage, so a clean, low-noise 5 V or 10 V reference is required for absolute accuracy. This page consolidates distributor pricing, pin-compatible alternatives, and practical signal-chain design guidance that goes beyond the manufacturer datasheet's basic specifications.
MPXC2012DT1 - 10 kPa Differential Pressure Sensor, 4-SSIP | NXP
The NXP MPXC2012DT1 is a 10 kPa (1.45 PSI) differential piezoresistive silicon pressure sensor in a 4-SSIP side-port module, delivering a full-scale output of 24 mV to 26 mV at 10 V excitation in a low-cost uncompensated chip-pak package without gel protection. This legacy Motorola/Freescale/NXP part is aimed at high-volume, low-pressure differential measurement applications where the host MCU performs amplification, temperature compensation, and calibration. A pressure sensor is a transducer that converts an applied pressure differential into a proportional electrical signal. The MPXC series uses a silicon diaphragm with piezoresistive strain gauges arranged in a Wheatstone bridge; when pressure is applied, the diaphragm flexes and the bridge becomes unbalanced, producing a millivolt-level output proportional to differential pressure. The uncompensated nature of the MPXC2012DT1 means the host system must linearize and temperature-compensate the raw mV signal. Key features include a 0 mV to 25 mV output span at 10 V excitation, a 0.128 inch (3.25 mm) female pressure port oriented to the side of the package, and a unidirectional differential pressure mode (positive on the front side). The 4-SSIP through-hole module mounts vertically on a PCB and accepts standard tubing via the integrated port, simplifying plumbing for airflow and liquid-level designs. Technically, the device uses a monolithic silicon strain-gauge bridge with laser-trimmed resistors for tight offset tolerance. The die-side bond wires and port geometry are optimized for low-pressure HVAC and medical-respiration airflow paths.

Typical applications include HVAC differential pressure sensing, medical respiration/airflow monitoring, altimeters and barometric helpers, level detection, and industrial process control. The MPXC2012DT1 is well suited for cost-sensitive airflow measurement where the system can absorb a discrete op-amp and calibration step. When designing, route the high-impedance bridge output traces away from switching noise sources and provide a Kelvin connection to the excitation source. Without gel protection, do not expose the die-side cavity to condensing humidity or direct water contact; mount the port facing away from dust streams.

The integrated bipolar op-amp front end and thin-film resistor network give a typical sensitivity of 45.9 mV/kPa with a maximum error of 1.5 % over the compensated temperature window. An absolute pressure sensor is a transducer that produces an output proportional to pressure referenced to a sealed vacuum cavity rather than ambient air. The MPXH6115A6U sits inside the broader sensor taxonomy as a piezoresistive silicon sensor -> MEMS pressure sensor -> absolute pressure transducer. Because the vacuum reference is built in, the device outputs a pressure reading that includes the local atmospheric component, which is ideal for sealed-cavity applications where atmospheric drift must be inherently rejected. Key features include a maximum pressure rating of 400 kPa (over-pressure survival to roughly 3.5x the full-scale operating range), ratiometric analog output that tracks VCC for ADC-friendly interfaces, and a typical current consumption of 6 mA.

Architecturally, the device combines a piezoresistive MEMS strain-gauge bridge with bipolar signal-conditioning silicon on the same die. This single-chip integration improves noise immunity and long-term drift compared with discrete bridge-plus-amplifier solutions. The ratiometric output simplifies MCU sampling because the ADC reference can share the sensor supply. Typical applications include engine manifold absolute pressure (MAP) sensing, barometric altimeters, weather stations, HVAC duct pressure monitoring, medical respiratory equipment, and tire pressure monitoring modules. The wide compensated temperature range and surface-mount form factor make it well suited for automotive under-hood and industrial environments. A primary design consideration is ratiometric ADC sampling: the sensor output scales linearly with VCC, so the microcontroller ADC reference must be derived from the same 5 V rail to preserve absolute accuracy. Decoupling VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin minimizes switching noise on the analog output.

The NXP MPXH6250A6T1 is a high temperature accuracy, integrated silicon absolute pressure sensor with on-chip signal conditioning and temperature compensation, housed in an 8-SOIC (7.50 mm width) surface mount package. The device measures absolute pressure from 20 kPa to 250 kPa (2.9 PSI to 36.26 PSI) and provides a ratiometric analog output from 0.3 V to 4.9 V. Originally developed by Motorola and Freescale (now NXP) and second-sourced by STMicroelectronics as part of the MPXx6250A series, this sensor targets engine control unit (ECU) manifold absolute pressure (MAP) sensing and other automotive-grade pressure measurement tasks. An absolute pressure sensor is a transducer that outputs a voltage proportional to the pressure measured relative to a sealed reference vacuum rather than to ambient atmosphere. It belongs to the broader sensor product category (sensor -> pressure sensor -> absolute pressure sensor -> MEMS-based piezoresistive sensor), commonly used to close the air-fuel feedback loop in gasoline direct-injection engines and to monitor boost pressure in turbocharged systems. The MPXH6250A6T1's 0-5 V output swings a span of roughly 230 kPa across 4.6 V, giving the MCU an analog digital-converter channel's worth of dynamic range without instrumentation amplification. Key features include a typical full-scale span of 4.6 V, accuracy better than 1.5% over 0 to 85 C per the manufacturer datasheet, and integrated thin-film resistor networks that trim offset, span and temperature coefficient at the wafer level. The SOIC-8 package exposes four port variants (ported axial, ported side, dual-port, no-port); the T1 suffix here selects the axial-port option. The device operates from a single 4.74 V to 5.46 V supply, sinks a typical 5 mA supply current, and includes EMI/RFI hardening on the output pin. The MPXH6250A6T1 uses a monolithic piezoresistive Wheatstone bridge diffused into a silicon diaphragm, followed by an on-chip bipolar op-amp stage that conditions and temperature-compensates the millivolt-level bridge output into the 0.3-4.9 V swing. The integrated thin-film laser-trimmed network cancels first-order temperature errors, while a second-order compensation is performed in software by the host ECU. The 8-SOIC packaging routes pressure into a forward axial port, and the internal gel isolation (where fitted) allows direct media contact on selected variants. Typical applications include automotive manifold absolute pressure (MAP) sensing for engine control units (ECUs), barometric air-pressure correction for fuel-injection strategies, HVAC refrigerant pressure monitoring, and industrial pneumatic control loops. Because the part is AEC-Q qualified by automotive pedigree, it also fits heavy-duty truck and motorcycle engine management. When designing with this device, route the analog output through an RC low-pass filter (typically 1 kohm / 100 nF) before the ADC input to suppress out-of-band noise and motor-borne spikes, and keep supply decoupling close to the VCC pin with a 100 nF ceramic plus 1 uF bulk. The axial port draws airflow over the gel-isolated die, so avoid kinking or filtering the inlet line.

What is an absolute pressure sensor? An absolute pressure sensor is a transducer which generates an electronic signal proportional to pressure measured relative to a sealed internal vacuum reference rather than ambient air. Absolute pressure sensors belong to the broader category of MEMS-based piezoresistive sensors and signal-conditioned pressure transducers, themselves a subclass of physical-environment sensors used in industrial, automotive, and medical instrumentation. They are differentiated from gauge pressure sensors (which reference atmosphere) and differential pressure sensors (which compare two ports). Key features include factory calibration over the 0 to 85 °C range, internal temperature compensation implemented in the on-chip bipolar op-amp and thin-film network, and ratiometric output that tracks the supply voltage for use directly with an analog-to-digital converter (ADC) referenced to the same rail. The integrated signal path eliminates the need for external signal conditioning in most applications. The MPXH6250A6U is built on a silicon piezoresistive strain-gauge bridge whose resistance changes with applied pressure. On-chip signal conditioning converts the small bridge differential to a buffered, temperature-compensated analog voltage. This architecture provides excellent noise immunity, fast response, and repeatable performance across the full operating range, while the SOIC-8 surface-mount package supports high-volume automated PCB assembly. Typical applications include manifold absolute pressure (MAP) sensing in fuel-injected and small engines, industrial process control, HVAC pressure monitoring, altimeter/barometric measurement, and consumer appliances requiring absolute pressure feedback. Its ratiometric analog output is well suited to direct connection to an automotive ECU or microcontroller ADC integrated in digital systems. When designing with this device, ensure a clean, regulated 5.0 V supply to maintain ratiometric accuracy, place decoupling capacitors close to the supply pin, and follow the port orientation specified for the A6U top-port SOIC package. For this configuration, do not exceed the rated pressure or temperature limits, otherwise the calibrated bridge network may be permanently damaged. The MPXH6250A6U is not a drop-in upgrade to the MPXH6300A6U family because the pressure range and sensitivity differ; use the family variant appropriate to your maximum system pressure.

Per the MPXH6250A series documentation, the part integrates on-chip bipolar op-amp circuitry and thin-film resistor networks that provide amplification, offset, span calibration and temperature compensation, eliminating the need for external signal conditioning. An absolute pressure sensor is a MEMS device whose internal reference cavity is sealed against a fixed vacuum, so the output represents pressure relative to that vacuum rather than to ambient air. Within the broader sensor taxonomy it sits under piezoresistive silicon pressure sensors -> pressure sensors -> transducers -> MEMS -> sensors. Absolute variants are differentiated from gauge (relative-to-atmosphere) and differential sensors and are used where the system must operate regardless of barometric drift - intake manifold, barometric altimetry, sealed enclosures and vacuum process control.

The transfer function is approximately Vout = 5.0 V * (0.0038 * P_kPa + 0.058) for accurate MCU-side conversion. The integrated 8-bit-trimmed calibration yields typical accuracy around 1.5% to 2.5% over the compensated range. Technically, the device combines a MEMS piezoresistive Wheatstone bridge with a CMOS signal-conditioning ASIC on the same silicon carrier. Temperature compensation is performed by on-chip thin-film resistors laser-trimmed at wafer level, which keeps calibration drift low and removes the cost of per-unit trimming. The 0.3 V to 4.9 V swing maps cleanly onto a 5 V ADC full scale, maximizing ADC dynamic range without external gain. Typical applications include automotive engine control (MAP sensing, EGR monitoring), HVAC blower and filter diagnostics, barometric altitude and weather instruments, industrial process monitoring, medical respiratory equipment and sealed-enclosure leak detection. In each case the sensor substitutes for a discrete amplified bridge circuit at a fraction of the design effort. When designing with this part, place 100 nF decoupling close to the supply pin and drive the analog output through a low-impedance buffer or directly into an ADC with a high-impedance input. The top-side tube port should be sealed with an O-ring and protected against moisture and contamination, and the hose should be sized to avoid pressure drops across the full flow range.
