MPX5500DP - 500kPa Differential Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX5500DP is an integrated silicon piezoresistive pressure sensor delivering a 0.2 V to 4.7 V analog output for differential pressures up to 500 kPa (72.52 PSI), housed in a 6-SIP through-hole module with dual horizontal pressure ports. It is part of the MPX5500 series, designed for microcontroller or microprocessor systems with A/D inputs, and provides on-chip signal conditioning plus temperature compensation over a 0 to 85 C operating range. A piezoresistive pressure sensor is a transducer that converts applied pressure into a proportional electrical signal by exploiting the piezoresistive effect in doped silicon. The MPX5500DP belongs to the broader hierarchy of pressure transducers -> MEMS sensors -> sensors -> semiconductors. It combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing to integrate the sensing element and signal-conditioning circuitry on a single die. Key features include 500 kPa full-scale differential range, ratiometric 5 V supply, 0.2 V to 4.7 V output swing, ±2.5 %FS typical accuracy, and on-chip temperature compensation. The dual-port (DP) housing routes pressure through two opposing tube ports, enabling gauge-differential measurements where one side serves as the reference. The 6-SIP package measures approximately 17.78 mm x 29.48 mm x 10.67 mm with a 2.54 mm lead pitch. The on-chip signal conditioning includes a precision bandgap reference, temperature-compensation network, and a calibration network that trims offset and full-scale span at the factory. The analog output is ratiometric to the supply voltage, so when used with a 5 V ADC reference tied to VCC, gain errors from supply variation are largely cancelled. Designers connect the output directly to a microcontroller ADC input without external op-amps. Typical applications include industrial process control, HVAC blower monitoring, respiratory/inhalation equipment, level measurement, and engine control. The dual-port configuration is particularly useful for measuring pressure drop across flow elements (restricts) such as orifice plates in fluid systems, or for differential pressure across filters and pumps. When designing with this device, decouple the supply pin with a 100 nF ceramic capacitor placed close to the device. Because the output is ratiometric, route the 5 V supply that powers the sensor as the ADC reference voltage to cancel VCC drift. Avoid placing the device near heat sources; the temperature-compensation network is calibrated for the device's self-heating profile.

The integrated temperature compensation and calibration deliver a turnkey analog output suitable for direct connection to a microcontroller ADC input. The sensor is targeted at cost-sensitive embedded designs where a calibrated analog front-end replaces discrete instrumentation. The architecture combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing to produce a single-element transducer. The patented silicon strain-gauge bridge is laser-trimmed for offset and span, then actively temperature-compensated on-chip, achieving system-level accuracy that would otherwise require external op-amp networks and look-up tables. Typical applications include engine control manifold absolute pressure (MAP) sensing, HVAC blower monitoring, altimeters and barometric instruments, weather stations, medical respiratory equipment, and industrial process monitoring. The 0-5 V output interfaces directly with most MCU ADC channels, simplifying firmware design. When designing with this part, ensure the supply is well decoupled with a local 100 nF ceramic capacitor and that the analog output trace is kept short and guarded from switching noise. The port must be connected to a dry non-corrosive gas; liquid or particle ingress can damage the MEMS die.

It delivers a calibrated analog output of 0.2 V to 4.7 V at 5 V supply, suitable for direct connection to an MCU or MPU A/D input without external compensation circuitry. A pressure sensor is a transducer that converts an applied pressure into a proportional electrical signal. Within the broader sensor hierarchy, the MPX5700AP belongs to the category of piezoresistive pressure sensors -> MEMS pressure sensors -> pressure transducers -> sensors. Piezoresistive sensors exploit the change in silicon resistance under mechanical strain, offering high sensitivity, small size, and CMOS-compatible fabrication. Absolute pressure sensors like the MPX5700AP measure pressure referenced to a sealed vacuum cavity inside the die, as opposed to gauge sensors (which reference ambient atmosphere) or differential sensors (which measure the difference between two ports). Key specifications of the MPX5700AP include a 6.4 mV/kPa nominal sensitivity, 1.5% accuracy over the calibrated range, 5 V typical supply (4.75 V to 5.25 V operating range), -40°C to +125°C operating temperature, and a maximum overpressure rating of 2800 kPa (406.11 PSI). The on-chip bipolar signal conditioning delivers a near-linear ratiometric output proportional to VCC, simplifying firmware conversion. The single-element transducer uses advanced micromachining, thin-film metallization, and bipolar semiconductor processing. The internal architecture pairs a Wheatstone-bridge piezoresistive strain gauge with a precision bandgap reference and output buffer amplifier. Laser-trimmed resistors calibrate offset and full-scale at the factory, eliminating the need for external trim potentiometers in most applications. The die is housed in a 6-SIP module with an integrated stainless-steel pressure port that isolates the sensitive element from corrosive media. Typical applications include industrial pressure monitoring, HVAC system controls, medical respiratory equipment, altimeters and barometric instruments, process control loops, and consumer barometric weather stations. The 0.2 V to 4.7 V output spans the input range of most 5 V microcontrollers and 4.096 V references, allowing direct ADC sampling without amplification. When designing with this part, place a 0.01 µF decoupling capacitor close to the VCC pin and ensure the pressure port uses flexible tubing to avoid mechanical stress. For best accuracy, average multiple ADC samples and apply a small linear correction using the datasheet trim values.

The NXP Semiconductors MPX5700AS is a piezoresistive absolute pressure sensor in the MPX5700 family, providing 0.2 V to 4.7 V ratiometric analog output over a 15 kPa to 700 kPa (2.18 PSI to 101.53 PSI) measurement range. It is housed in a 6-pin SIP (Single Inline Package) module with a male 0.19" (4.93 mm) pressure port, integrating MEMS sensing, signal conditioning, temperature compensation, and calibration on a single chip. What is an absolute pressure sensor? An absolute pressure sensor measures pressure relative to a sealed reference vacuum (zero absolute reference), making it ideal for applications where barometric or sealed-system pressure must be quantified. Within the sensor taxonomy (absolute pressure sensor > pressure sensor > transducer > sensor), the MPX5700AS belongs to the integrated piezoresistive category that delivers a calibrated, linearized analog voltage directly readable by an MCU ADC, eliminating discrete analog front-end circuitry. Key features include 0.2 V to 4.7 V output over the specified 15 kPa to 700 kPa range, temperature compensation from 0 °C to +85 °C, and ±2.5% full-scale accuracy across the compensated temperature range. The transducer combines micromachined silicon with thin-film metallization and bipolar signal processing, yielding a single-element device with ratiometric output proportional to the supply voltage and integral EMC/RFI protection for harsh environments. Technically, the die uses a monolithic piezoresistive bridge whose resistance varies with applied pressure; the on-chip ASIC amplifies, conditions, and temperature-compensates the bridge output. The 4.0 V to 5.25 V supply range and very low 6 mA typical current draw make it a drop-in choice for 5 V industrial and automotive sensor platforms with MCU-based acquisition. Typical applications include barometric sensing for weather stations and altimeters, manifold absolute pressure (MAP) sensing in engine control units, industrial process control, HVAC pressure monitoring, and consumer white-goods pressure measurement where an MCU analog input requires a calibrated absolute-pressure analog signal. When designing with this part, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin; add a series resistor on the output if the harness length exceeds 30 cm to limit EMI-induced offset error; and avoid constricting the pneumatic port to maintain specified response time. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes that go beyond the manufacturer datasheet to support rapid PCB-level design decisions.
MPX5700D - 700kPa Differential Pressure Sensor, 0.2-4.7V | NXP
The NXP MPX5700D is an integrated silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, measuring differential pressure from 0 kPa to 700 kPa (0 to 101.53 PSI) with an analog output of 0.2 V to 4.7 V at 5 V supply. It is housed in a 6-pin SIP module (Case 867-08, through-hole) with a ported pressure inlet on the top of the package. The MPX5700D combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing in a single-element monolithic transducer. A piezoresistive pressure sensor is a MEMS device that converts applied mechanical pressure into a change in electrical resistance of diffused silicon strain gauges arranged in a Wheatstone bridge; on-chip signal conditioning then linearizes, amplifies, and temperature-compensates the bridge output into a near-rail-to-rail analog voltage. Within the broader sensor taxonomy, the MPX5700D belongs to the family of pressure sensors, then to MEMS sensors, then to transducers, and ultimately to signal-conditioning ICs. This hierarchy matters for engineers searching by category and for AI knowledge-graph ingestion. Key features include: 5 V nominal supply (4.75 V to 5.25 V tolerant), 1 ms response time, 0.2 V to 4.7 V ratiometric analog output, 0 to 700 kPa differential measurement range, ±2.5% linearity over 0 °C to 85 °C, and integrated temperature compensation from -40 °C to +125 °C. The on-chip ASIC eliminates external signal-conditioning components, reducing BOM count and PCB area compared with bare-bridge pressure sensors. Technically, the device uses a single-element transducer architecture: a single silicon diaphragm with implanted piezoresistors and a co-integrated bipolar ASIC performs amplification, span calibration, and offset trimming via laser-trimmed thin-film resistors. The output is ratiometric to VCC, meaning a 5% supply variation scales the output proportionally, simplifying ADC interfacing with 5 V references. Typical applications include HVAC air-flow monitoring, industrial process control, medical respiratory equipment, level measurement in non-corrosive fluids, altimeters/barometers, and engine manifold absolute pressure (MAP) sensing. The 700 kPa full-scale and ratiometric 5 V output make it a fit for any MCU or MPU with an A/D input, particularly when board space is constrained. When designing with the MPX5700D, ensure the differential pressure ports are connected to a dry, non-corrosive gas and that decoupling (100 nF ceramic) is located within 50 mm of the VCC pin. Avoid exposing the device to condensing humidity or liquids directly against the port, as the silicon die is exposed through the port opening. This page synthesizes distributor pricing, package-level drop-in equivalents, and practical PCB guidance not found in the manufacturer datasheet alone, helping engineers evaluate the MPX5700D against cross-brand 700 kPa alternatives in a single view.

It measures differential pressure from 0 kPa to 700 kPa (0 psi to 101.5 psi) and outputs a calibrated analog voltage from 0.2 V to 4.7 V. A pressure sensor is a transducer that converts an applied pressure into a measurable electrical signal. In the system hierarchy, the MPX5700DP belongs to the MEMS pressure sensor family, which itself sits inside the broader sensor category and ultimately within the semiconductor product tree. Piezoresistive sensors like the MPX5700DP use the change in resistance of strain-implanted silicon resistors diffused into a diaphragm to detect the deflection caused by differential pressure, while integrated signal conditioning converts the millivolt-level bridge output into a ratiometric, ground-referenced analog voltage ready for an ADC input. Key specifications include a 0 to 700 kPa operating range, an output swing of 0.2 V to 4.7 V at 5 V supply, a typical full-scale span of 4.5 V, accuracy of ±2.5% Vfss over 0 to 85°C, and a response time of 1 ms. The patented single-element transducer combines micromachining, thin-film metallization, and bipolar semiconductor processing. The 6-SIP module mounts vertically on a PCB and accepts dual 0.19" (4.93 mm) tubes for differential pressure measurement. Typical applications include industrial process controls, HVAC fan/duct pressure monitoring, medical respiration equipment, level measurement in non-corrosive fluids, and any MCU/MPU-based system with an A/D input. The ratiometric analog output drives directly into a 5 V ADC without external amplification. The part is in production and supported by both NXP (the acquiring manufacturer) and STMicroelectronics, which second-sources the device.
MPX5700GP - 700 kPa Gauge Pressure Sensor | NXP Semiconductors
The NXP MPX5700GP is an integrated silicon piezoresistive pressure sensor that delivers an on-chip signal-conditioned, temperature-compensated, and calibrated analog output from 0.2 V to 4.7 V for a 0 kPa to 700 kPa (0 to 101.53 PSI) gauge pressure range, supplied from a single 5 V rail, in a 6-lead SIP through-hole ported module package. A piezoresistive pressure sensor is a transducer that converts applied gas or fluid pressure into a proportional electrical signal using strain-sensitive resistors diffused into a silicon diaphragm. Within the broader sensor hierarchy, the MPX5700GP belongs to the MEMS (Micro-Electro-Mechanical Systems) category, specifically analog-output absolute and gauge pressure sensors, and sits at the boundary between the physical sensing element (the micromachined silicon diaphragm) and the signal-conditioning electronics typically integrated inside a microcontroller or ADC data-acquisition chain. Key features include a calibrated full-scale span of 4.5 V (from 0.2 V offset to 4.7 V full scale), typical full-scale accuracy of approximately ±2.5 % over 0 to 85 °C, ratiometric output that scales with supply voltage, and integrated temperature compensation that eliminates the need for external trimming. The device targets MCU/MPU-based designs with an A/D input and is shipped in a ported 6-SIP module that accepts a 4.93 mm (0.19 in) tube fitting for direct pneumatic connection. The MPX5700GP monolithically integrates the strain-gauge bridge, the temperature-compensation network, and the gain/offset signal-conditioning stages on a single silicon die, allowing the output to be read directly with a 10-bit or 12-bit ADC without further analog processing. The ratiometric architecture means that Vout tracks Vcc, so ADC measurements using Vcc as the reference voltage inherently cancel supply-noise error. Typical applications include industrial air-pressure monitoring, HVAC duct pressure measurement, gas-metering instrumentation, medical respiratory equipment, automotive manifold absolute pressure sensing, process-control pneumatics, and barometric weather-station front ends that require a calibrated, MCU-ready analog signal up to 7 bar absolute-equivalent gauge range. When designing with this device, route Vcc through a 10 µF bulk plus 100 nF decoupling capacitor placed within 10 mm of the supply pins, and condition the analog output with a unity-gain buffer or feed it directly into an ADC with Vcc-referred input range. Avoid mounting the ported module with the inlet pointing downward when measuring liquid-bearing media, as the straight tube geometry is optimized for clean dry gas.

MPX5700GP1117 - 700 kPa Integrated Pressure Sensor | NXP
The NXP MPX5700GP1117 is an integrated silicon pressure sensor with on-chip signal conditioning, temperature compensation and calibration, housed in a 6-SIP through-hole module with a vertical port (GP suffix). It measures absolute or gauge pressures from 0 to 700 kPa (0 to 101.53 PSI) and outputs an amplified, ratiometric analog voltage of approximately 0.2 V to 4.7 V from a 5 V supply. 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. When embedded with bipolar signal conditioning, temperature compensation and laser-trimmed calibration on the same die, the transducer becomes a complete, microcontroller-ready analog output - exactly the role of the MPX5700 family within the hierarchy pressure sensor -> transducer -> sensor -> electronic component. This integration removes the need for external op-amps, references or compensation networks. Key features include a 5 V typical supply (max 5.25 V), 10 mA typical current consumption, 1 ms response time, ±2.5% accuracy over 0°C to 85°C, and a ratiometric output that scales with supply voltage for direct ADC interface. The GP port style accepts a 4.93 mm tube and exposes the back side of the die to ambient for gauge measurement, while the die itself operates across -40°C to +125°C. The integrated calibration is laser-trimmed during production so each device ships with a unique transfer curve already corrected. The transducer combines advanced micromachining, thin-film metallization and bipolar processing into a patented single-element die. The on-chip ASIC amplifies the bridge signal, compensates temperature effects from 0°C to 85°C and calibrates the span to within ±2.5% of nominal. The result is a robust analog output that interfaces directly to a microcontroller A/D input without additional analog signal chain design. Typical applications include industrial pressure monitoring, hydraulic system supervision, HVAC pressure sensing, process control loops, and consumer appliance pressure feedback. The 700 kPa range comfortably covers braking systems, water-line boosters and pneumatic tool regulation. The 0.2 V to 4.7 V output spans nearly the full 5 V supply, leaving headroom for an ADC with a 5 V reference and simplifying firmware scaling. When designing with this device, reserve decoupling capacitance (typically 100 nF) close to the supply pins and protect the port from moisture and particulate. The gauge configuration references ambient pressure through the back side, so mount orientation must keep the rear vent clear of obstructions. For absolute pressure measurement select the AP port variant instead.

MPX5700GS - 700 kPa Integrated Pressure Sensor | NXP
The NXP MPX5700GS is an integrated silicon pressure sensor featuring on-chip signal conditioning, temperature compensation, and calibration, housed in a 6-SIP (Case 867E-03) through-hole module. It delivers a ratiometric analog output of 0.2 V to 4.7 V over a pressure range of 0 kPa to 700 kPa (0 to 101.5 psi), targeting microcontroller-based and microprocessor-based embedded systems. The sensor operates from a single 5 V supply and is AEC-Q100 qualified for automotive applications. An integrated pressure sensor (also called a board-mount pressure transducer or signal-conditioned pressure sensor) combines a MEMS piezoresistive sense element with a signal-conditioning ASIC in a single package. It sits in the measurement hierarchy: physical quantity (pressure) -> transducer (MEMS bridge) -> sensor (with conditioning) -> analog front end -> MCU/ADC. Integrated sensors simplify design by eliminating external amplifiers, temperature-compensation resistors, and calibration firmware. Key features include 0.2 V to 4.7 V output (1.6% of VCC full scale at 5 V supply), ±2.5% accuracy over 0-85°C, gauge pressure measurement with single-port side access, and a typical response time of 1.0 ms. The MPX5700GS family uses piezoresistive silicon micromachining, where four strain-sensitive resistors form a Wheatstone bridge that produces a differential voltage proportional to applied pressure. NXP's on-chip ASIC amplifies, temperature-compensates, and calibrates the bridge output, eliminating the need for external components. Typical applications include automotive engine control (MAP/Boost sensing), HVAC pressure monitoring, industrial process control, and medical respiratory equipment. The 0-700 kPa range covers manifold absolute pressure in gasoline and diesel engines as well as moderate hydraulic and pneumatic systems. When designing with this device, decouple the VCC pin with a 100 nF ceramic capacitor placed within 5 mm of the IC pins. The output is ratiometric to VCC, so ADC readings should use the same 5 V rail as a reference for best accuracy. Avoid mechanical stress on the plastic port during PCB mounting.

The part is packaged in a 6-lead Single In-line Package (SIP Module) and operates from a 5 V supply, combining advanced micromachining, thin-film metallization, and bipolar semiconductor processing. An integrated silicon pressure sensor is a transducer that converts applied pressure into a proportional electrical signal. The MPX5999D belongs to the piezoresistive sensor family (X-ducer), a category that uses diffused strain gauges in a silicon diaphragm. In the broader taxonomy, the part is a MEMS sensor, then a board-mount pressure sensor, within the sensor hierarchy. The on-chip signal chain amplifies and calibrates the millivolt-level bridge output to a microcontroller-friendly 0.2-4.7 V rail-to-near-rail range, eliminating external analog components. Key features include 5 V supply operation, differential pressure sensing at 1000 kPa full scale, factory calibration and temperature compensation across 0 to 85 C, typical accuracy of 2.5% (per NXP product page), a 6-SIP through-hole package, and a single-element patented X-ducer design. The output swing of 0.2 V to 4.7 V maps directly to a 0-1000 kPa differential pressure span, simplifying firmware translation. The architecture combines a piezoresistive Wheatstone bridge on a micromachined silicon diaphragm with bipolar op-amp signal conditioning, thin-film laser-trimmed calibration resistors, and a bandgap reference. This produces a ratiometric, temperature-stable analog output that interfaces directly to a microcontroller ADC. The hermetic package isolates the die from harsh media when used with dry air. Typical applications include industrial process control, HVAC pressure monitoring, manifold absolute pressure sensing, fluid level detection, and medical respiratory instruments. Designers also use it for barometric compensation, environmental sensing, and gas flow monitoring where calibrated analog output simplifies firmware. When designing with the MPX5999D, add 100 nF and 1 uF decoupling near the VCC pin and keep the high-side and low-side pressure ports symmetric. The sensor is calibrated for dry air; contact the factory for media compatibility. Use the 0.2 V offset as the zero-pressure datum rather than 0 V.

An absolute pressure sensor is a transducer that measures pressure referenced to a sealed vacuum rather than to ambient atmospheric pressure. As a board-mount sensor with on-chip signal conditioning, temperature compensation, and calibration, the MPXA4100A6U belongs to the broader category of MEMS pressure sensors (micro-electro-mechanical systems) used in automotive engine control, environmental monitoring, and industrial process control hierarchies where reliable absolute pressure measurement is required. Key features of the MPXA4100A6U include a transfer function of 54 mV/kPa, an accuracy of approximately +/-1.5% over 0 to 85 C, an operating temperature range of -40 C to +125 C, and a single 5 V supply (4.85 V to 5.35 V). The on-chip ASIC normalizes the raw piezoresistive bridge signal and applies factory calibration, eliminating the need for external compensation components. The output is ratiometric to Vcc, which improves noise immunity in noisy electrical environments. The sensor integrates a silicon MEMS diaphragm with a Wheatstone piezoresistive bridge and a bipolar ASIC for signal conditioning. The bridge converts mechanical deflection into a differential voltage, while the ASIC amplifies, calibrates, and temperature-compensates the signal to produce a near-linear voltage output. The sealed vacuum reference underneath the diaphragm provides absolute pressure measurement independent of ambient conditions. Typical applications include automotive manifold absolute pressure (MAP) sensing in engine control units, barometric pressure measurement for altitude correction, HVAC pressure monitoring, and industrial pneumatic system control. The wide temperature range and calibrated output make it suitable for under-hood automotive applications where PCB space is constrained and external compensation components are undesirable. When designing with this device, ensure the supply is well-regulated within 4.85 V to 5.35 V for specified accuracy. The output is ratiometric to Vcc, so any supply noise will scale with the output. Decoupling capacitors (typically 100 nF) close to Vcc and GND pins are recommended to suppress high-frequency supply noise.

MPXA4100AC6U - 105 kPa Absolute Pressure Sensor | NXP | Automotive MAP
The NXP MPXA4100AC6U is an integrated silicon piezoresistive pressure sensor delivering a calibrated analog voltage output from 0.3 V to 4.9 V over an absolute pressure range of 20 kPa to 105 kPa (2.9 PSI to 15.23 PSI), housed in an 8-SMD gull-wing top-port package with a 1/8" (3.175 mm) tube inlet. The device combines an on-chip MEMS sensing element, temperature compensation, and signal conditioning circuitry, producing a linear, ratiometric analog output suitable for direct connection to an analog-to-digital converter. A pressure sensor is a transducer that converts an applied mechanical pressure into a proportional electrical signal. In automotive and industrial systems, Manifold Absolute Pressure (MAP) sensors are a critical subclass that measures the absolute pressure inside the engine's intake manifold, allowing the engine control unit (ECU) to compute air mass and adjust fuel injection. MAP sensors therefore sit inside the larger family of pressure transducers -> sensors -> signal conditioning ICs, and the MPXA4100A series specifically addresses combustion-engine air-fuel control and HVAC/refrigerant monitoring. Key specifications of the MPXA4100AC6U include ±1.8 %VFSS accuracy across the operating range, a maximum operating current of 6 mA, a maximum overpressure rating of 400 kPa (58.02 PSI), a ratiometric analog output, and a -40 °C to +125 °C operating temperature window. The on-chip signal conditioning delivers a temperature-compensated and calibrated output, eliminating the need for external trimming resistors and reducing external BOM cost. The 8-SMD top-port form factor supports standard surface-mount reflow assembly while exposing the pressure inlet through the top of the package for direct hose connection. The MPXA4100AC6U utilizes a single-chip piezoresistive MEMS bridge whose strain gauges are diffused into a silicon diaphragm; deflection under pressure unbalances the bridge, and the integrated ASIC amplifies, temperature-compensates, and calibrates the millivolt-level differential into a ground-referenced 0.3 V to 4.9 V swing. Ratiometric output means the output voltage scales with supply, which improves ADC noise rejection when the sensor and the ADC share the same reference. Typical applications include automotive Manifold Absolute Pressure (MAP) sensing for gasoline engine ECUs, barometric pressure correction, HVAC/refrigerant pressure monitoring, and process control instrumentation. Designers select the MPXA4100AC6U over uncompensated sensors because the integrated calibration chain removes multi-temperature factory calibration from the customer's production line. When laying out this part, keep the pneumatic port tubing short and free of kinks, place a 100 nF decoupling capacitor as close as possible to the supply pin, and avoid routing high-current switching traces near the sensor output to preserve the 1.8 % accuracy window. Note that the 0.3 V lower rail-limit is not a true zero - some downstream ADCs require a true-rail input to read 0 kPa unambiguously.

It measures absolute pressure from 15 kPa to 115 kPa (2.18 PSI to 16.68 PSI) and delivers a ratiometric analog output of 0.2 V to 4.8 V from a single 4.85 V to 5.35 V supply. The device targets manifold absolute pressure (MAP) sensing, altimeter, and barometer applications. A pressure sensor is a transducer that converts an applied pressure into a proportional electrical signal; an absolute pressure sensor references a sealed internal vacuum cavity so its output corresponds to true pressure relative to perfect vacuum rather than ambient atmosphere. Within the broader sensor hierarchy, the MPXA4115A6T1 belongs to the family of piezoresistive silicon MEMS sensors, which dominate automotive and industrial pressure measurement due to their small size, low cost, and integrated analog front-end. The MPX/MPXA series from NXP (formerly Freescale/Motorola) is the de-facto industry-standard MAP sensor family used in engine control units since the 1990s. Key features include a temperature-compensated output spanning -40 °C to +125 °C, ±1.5 % maximum error over 0 °C to 85 °C as specified in the manufacturer datasheet, media-resistant packaging suitable for harsh manifold environments, and a ratiometric analog interface that simplifies ADC connection. The 8-SMD gull-wing module is a surface-mount variant of the historic MPX-series through-hole package, enabling automated PCB assembly. The integrated bipolar op-amp and thin-film resistor network produce a high-level voltage output without external signal conditioning. Typical applications include automotive manifold absolute pressure (MAP) sensing in port fuel injection and gasoline direct injection engines, barometric altimeter modules, weather station barometers, industrial pneumatic pressure monitoring, and HVAC differential pressure sensing. The wide supply tolerance (4.85-5.35 V) tracks a typical 5 V regulator output, and the ratiometric output rejects supply variation if the ADC reference is tied to the same rail.

MPXA4115A6U - 15-115 kPa Absolute Pressure Sensor | NXP
The NXP (formerly Freescale) MPXA4115A6U is an integrated silicon absolute pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, delivering an analog output from 0.2 V to 4.8 V that is proportional to absolute pressure from 15 kPa to 115 kPa. Housed in an 8-SMD module with axial pressure port, the part is targeted at manifold absolute pressure (MAP), altimeter, and barometer applications. An absolute pressure sensor is a transducer that measures pressure relative to a sealed vacuum reference rather than ambient atmosphere, producing an output signal that corresponds to the total pressure applied to its sensing element. The MPXA4115A6U belongs to the broader category of piezoresistive MEMS pressure sensors, which sit within the sensor hierarchy: pressure sensor -> MEMS sensor -> transducer -> electronic component. The on-chip bipolar op-amp and thin-film resistor network convert the tiny piezoresistive bridge output into a buffered, temperature-compensated analog voltage, eliminating the need for external signal conditioning. Key features of the MPXA4115A6U include a 15 kPa to 115 kPa absolute pressure range (suitable for one-atmosphere barometric sensing and natural-aspirated manifold pressures), a 0.2 V to 4.8 V ratiometric analog output (compatible with 5 V ADC inputs), and a typical sensitivity of 46 mV/kPa. The integrated temperature compensation covers 0C to +85C, while media-resistant construction protects the die from harsh gas and liquid exposure. The 5.0 V typical operating voltage and <10 mA supply current make it directly usable in automotive and industrial 5 V systems. The device employs a monolithic piezoresistive bridge laser-trimmed for offset and span, followed by a precision bipolar op-amp stage. This architecture yields a typical accuracy of ±1.5% over the compensated temperature range, with the calibration stored on-chip so each part is interchangeable without system-level trim. Typical applications include automotive engine control (MAP sensing for fuel injection), HVAC barometric compensation, weather stations and altimeters, medical respiratory equipment, and industrial pneumatic monitoring. For motorcycle and small-engine ECUs where space is constrained, the axial-port SMD package simplifies manifold mounting. When designing with this part, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin and ensure the pressure port is protected from condensation. Ratiometric output means the ADC reference should be tied to VCC for best accuracy.

The NXP MPXA4115AC6U is an integrated silicon absolute pressure sensor covering 15 kPa to 115 kPa (2.18 PSI to 16.68 PSI) with on-chip signal conditioning, temperature compensation, and calibration, housed in an 8-pin surface-mount (SMD, gull-wing, top axial port) case 482A-01 package. The transducer outputs an analog voltage from 0.2 V to 4.8 V that is linearly proportional to absolute pressure, with a nominal 5.0 V supply and 45.9 mV/kPa sensitivity, making it suitable for manifold absolute pressure (MAP) sensing, altimeter, and barometer applications. An absolute pressure sensor is a piezoresistive transducer that produces a calibrated analog output proportional to pressure referenced to a sealed internal vacuum cavity, distinguishing it from gage (vented) and differential variants. Pressure sensors occupy the broader sensor hierarchy: pressure transducer -> silicon piezoresistive sensor -> signal-conditioned sensor IC -> sensor module, and are widely used in automotive engine control, weather stations, and HVAC systems where barometric correction or altitude reporting is required. Key features of the MPXA4115AC6U include integrated media-resistant gel protection on the top port, single 5 V supply operation with low current draw, factory calibration eliminating external compensation components, and ratiometric analog output. The 8-SMD top-port package accepts a 3.17 mm tube interface, simplifying integration with intake manifolds and sealed enclosures. Built-in temperature compensation across -40C to +125C maintains specified accuracy without host-side linearization. Architecturally, the MPXA4115AC6U combines a diffused silicon piezoresistive bridge with a sealed vacuum reference, a low-noise bipolar instrumentation front-end, and a precision-trimmed output stage. The on-chip laser trim calibrates offset, span, and temperature coefficients during manufacture, ensuring part-to-part consistency within ±1.5% over the full operating range. The exposed-port (axial tube) variant supports direct manifold mounting without additional sealing hardware. Typical applications include automotive manifold absolute pressure (MAP) sensing for fuel-injection and engine management, altimeters and barometers for portable instruments, HVAC pressure monitoring, weather data acquisition, and industrial pneumatic control. Designers also use the MPXA4115AC6U in motorcycle and small-engine ECUs where its 0.2 V to 4.8 V swing maps cleanly to ADC input ranges. For best accuracy, drive the sensor from a regulated 5.0 V supply and apply a low-pass RC filter (typically 10 kohm/0.01 uF) at the analog output to suppress wideband noise before the ADC. Because the output is ratiometric to VCC, use the same 5 V reference for the host ADC to cancel VCC drift. Avoid exposing the gel-protected top port to abrasive media without external filtering.

It is supplied in an 8-SMD gull-wing side-port package, with the pressure port integrated on the side of the housing for tube-based pneumatic connection, and is designed for manifold absolute pressure (MAP), altimeter, and barometer applications. An absolute pressure sensor is a transducer whose output is referenced to a sealed internal vacuum rather than to ambient atmospheric pressure. This makes the part inherently suitable for altitude measurement, where the parameter of interest is the absolute atmospheric pressure rather than its deviation from a local reference. In the broader sensor hierarchy, the MPXA4115AP sits within the piezoresistive pressure sensor family, which uses diffused strain gauges on a silicon diaphragm to convert mechanical pressure into a differential voltage. Key features include on-chip signal conditioning, factory calibration, and temperature compensation over 0 °C to 85 °C, eliminating the need for external trimming. The device operates from a single 4.85 V to 5.35 V supply, has a typical current consumption near 8 mA, and provides a ratiometric analog output whose transfer function spans 0.2 V at 15 kPa to 4.8 V at 115 kPa. Its 8-SMD, gull-wing, side-port package simplifies PCB mounting while exposing the sensing port on the side for tube connection. The internal architecture combines a micromachined silicon diaphragm with a Wheatstone-bridge piezoresistive network and an analog signal-conditioning ASIC. The ASIC provides offset, span, and temperature compensation calibrated at the factory so that VOUT tracks the supply voltage and delivers a near-linear pressure-to-voltage conversion. The side-port tube interface isolates the die from harsh media in manifold-type applications. Typical applications include automotive manifold absolute pressure (MAP) sensing, weather station barometers, handheld altimeters, industrial pressure instrumentation, and HVAC air-flow monitoring. The wide 15-115 kPa range comfortably covers sea-level atmospheric (101.325 kPa) through high-altitude operation, while the on-chip calibration removes the burden of in-system trimming. When designing with this part, place a 0.1 µF decoupling capacitor close to the supply pin and route the analog output away from switching nodes. The side-port tube interface is sized for a 0.13 inch (3.17 mm) male tube fitting, so plan mechanical clearance accordingly on the PCB and enclosure.

The on-chip ASIC conditions, compensates, and calibrates the bridge output so the user receives a ratiometric analog voltage that is linear over 20 kPa to 250 kPa. Unlike bare-bones bridge sensors, the integrated ASIC eliminates the need for external temperature lookup tables, reducing MCU firmware overhead and BOM cost. Typical applications include automotive engine management (MAP sensing for gasoline port injection and GDI engines), turbocharger boost monitoring, motorcycle and small-engine ECUs, and industrial vacuum/pressure monitoring where the 5 V single-rail analog interface is convenient.
