MPX5999D - 1000kPa Differential Pressure Sensor 6-SIP | NXP
The NXP MPX5999D is an integrated silicon pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, measuring differential pressure from 0 to 1000 kPa (0 to 145.04 PSI) and outputting a calibrated analog voltage from 0.2 V to 4.7 V. 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.

MPXA4100A6U - 20-105kPa Absolute Pressure Sensor
The NXP MPXA4100A6U is an integrated silicon piezoresistive pressure sensor designed for manifold absolute pressure (MAP) sensing, delivering a calibrated analog output of 0.3 V to 4.9 V over a 20 kPa to 105 kPa (2.9 PSI to 15.23 PSI) absolute pressure range in an 8-pin SOP (SMD) module with a vertical port. 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.

The NXP MPXA4115A6T1 is a media-resistant, integrated silicon absolute pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, housed in an 8-pin SMD module package. 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. When designing with this device, ensure the pressure port O-ring is properly seated and the media compatibility of the gel-protected port with the measured media is confirmed per the manufacturer datasheet.
MPXA4115A6U - 15-115 kPa Absolute Pressure Sensor | NXP

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.
MPXA4115AC6U - 15-115 kPa Absolute Pressure Sensor | NXP
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.

What is a MAP sensor? A Manifold Absolute Pressure sensor is a piezoresistive transducer used in engine control units to measure absolute air pressure inside the intake manifold. The measurement is fed into the ECU to compute the required fuel quantity per cylinder; it sits inside the broader sensor hierarchy of pressure sensor -> piezoresistive transducer -> MEMS sensor -> semiconductor IC. The MPXA4250A6U integrates a monolithic silicon strain-gauge bridge with laser-trimmed thin-film resistors, so no external op-amp or temperature-compensation network is required. Key specifications include a supply voltage range of 4.85 V to 5.35 V (5 V nominal), an analog output swing of 0.2 V to 4.9 V (approximately 20 mV/kPa sensitivity), an operating temperature range of -40 C to +125 C, and a response time of 1.0 ms. The full-scale accuracy is approximately +/-1.5% over the compensated temperature range, which is sufficient for closed-loop fuel control without per-unit calibration. At the architecture level the device uses a single-chip piezoresistive Wheatstone bridge diffused into a silicon diaphragm, with the diaphragm deflection proportional to applied pressure. 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. The wide 250 kPa full-scale accommodates naturally aspirated and moderately boosted engines. When designing with the MPXA4250A6U, place a 0.01 uF decoupling capacitor close to the supply pin and add a small RC low-pass filter on Vout if the ADC sample rate is high relative to the 1 ms response. The pressure port must use the correct O-ring and manifold geometry to avoid hysteresis and pressure drop.

It integrates on-chip bipolar op-amp circuitry and thin-film resistor networks to deliver a ratiometric analog output of 0.2 V to 4.7 V from a 5 V supply, with a typical full-scale span of 4.5 V. An absolute pressure sensor is a transducer that measures pressure relative to a perfect vacuum sealed inside its reference chamber, as opposed to a gauge sensor that references ambient atmospheric pressure. The MPXA6115AC6T1 belongs to the broader hierarchy of MEMS (Micro-Electro-Mechanical Systems) sensors, which combine mechanical sensing elements with on-chip signal conditioning; it is a specific member of the integrated pressure sensor family, more granularly classified as an absolute-pressure-type piezoresistive transducer with embedded analog front-end. This integration eliminates external compensation circuitry and reduces design footprint for system engineers. Key differentiating features include ±1.5% accuracy over 0°C to 85°C, a 5 V single-supply rail, and built-in electromagnetic interference (EMI) protection. The on-chip temperature compensation spans -40°C to +125°C, and the small-form-factor 8-SMD package with axial top port simplifies pneumatic tubing integration.

It integrates on-chip bipolar op-amp circuitry and thin-film resistor networks to provide a calibrated, temperature-compensated analog output of 0.2 V to 4.7 V ratiometric with a 5 V supply, with a typical sensitivity of 45.9 mV/kPa. The supply voltage range is 4.75 V to 5.25 V. An absolute pressure sensor measures pressure relative to a sealed internal vacuum reference rather than ambient atmosphere, producing a stable output that correlates directly with absolute barometric pressure. The MPXA6115AC6U belongs to the integrated pressure sensor category, sitting within the broader hierarchy of MEMS sensors -> transducers -> sensors -> electronic components. Absolute pressure variants are distinguished from gauge pressure sensors (which reference ambient) and differential pressure sensors (which measure the difference between two ports); this makes absolute types ideal for sealed-system measurements where ambient drift must be excluded.

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.
