MPXH6300AC6T1 - 304kPa Absolute Pressure Sensor, 5V, SOIC-8 | NXP
The NXP MPXH6300AC6T1 is a high-temperature accuracy integrated silicon pressure sensor that measures absolute pressure from 20 kPa to 304 kPa (2.9 PSI to 44.09 PSI) and produces a ratiometric analog output of 0.3 V to 4.9 V from a 5 V supply, housed in an 8-pin SOIC (0.335 inch / 8.50 mm width) package with a top-side male tube port (0.13 inch / 3.3 mm). A pressure sensor (also called a pressure transducer or piezoresistive sensor) is a device that converts an applied physical pressure into a proportional electrical signal. Absolute-pressure variants measure pressure referenced to a sealed vacuum cavity rather than to ambient air, which makes them ideal for applications requiring pressure readings independent of weather or altitude. The MPXH6300A series belongs to the hierarchy pressure sensor -> transducer -> sensor -> electronic component, and uses on-chip bipolar op-amp signal conditioning plus thin-film resistor networks for temperature compensation and calibration. Key features include a 5.0 V single-supply operation, integrated temperature compensation from -40 C to +125 C, ratiometric analog output, and a top-port tube inlet sized for hose barb connections. The SOIC-8 surface-mount package with exposed top port supports pick-and-place assembly while keeping the pressure inlet accessible for media isolation. The on-chip calibration provides high accuracy across the automotive temperature range without external trimming. Technically, the device uses a piezoresistive MEMS die suspended on a sealed reference cavity; under applied pressure the diaphragm deflects and the embedded Wheatstone bridge changes resistance, with on-chip amplification linearising the response. A 5 V supply produces a near rail-to-rail output swing that interfaces directly with most microcontrollers and ADCs without additional gain stages. Note: per verified web data, the operating pressure shown is 2.9 PSI to 44.09 PSI (20 kPa to 304 kPa), so a separate clinical low-pressure variant may be required for medical applications. Typical applications include small-engine manifold absolute pressure (MAP) sensing, automotive engine control units, fuel-injected engine boost monitoring, HVAC pressure measurement, and industrial pneumatic control. The AEC-Q100 qualified variant supports underhood automotive deployments. For best results, route the sensor port with short manifold tubing to minimise pneumatic lag, place a 100 nF decoupling capacitor directly at the supply pin, and protect the inlet from moisture and particulate ingress with an appropriate filter. Avoid touching the port during board cleaning because solvents and residue can degrade the seal.

MPXH6300AC6U - 20-304kPa Absolute Pressure Sensor 5V SOP-8 | NXP
The NXP MPXH6300AC6U is a high-temperature-accuracy integrated silicon absolute pressure sensor with on-chip bipolar op-amp circuitry and thin-film resistor networks, providing a calibrated, temperature-compensated analog output proportional to applied pressure. It measures absolute pressure from 20 kPa to 304 kPa (2.9 PSI to 44.09 PSI), translating that range into an output voltage span of 0.3 V to 4.9 V from a 5 V supply, with a typical sensitivity of 16.2 mV/kPa. The device is offered in an 8-pin SOP (SSOP-equivalent, 0.335 inch / 8.50 mm width) package with a top axial port accepting a 0.13 inch (3.3 mm) tube for manifold-style pneumatic connection. An absolute pressure sensor is a MEMS-based transducer that measures pressure referenced to a sealed internal vacuum rather than ambient atmosphere, producing a stable reading independent of weather or altitude. These sensors sit inside the broader sensor hierarchy: pressure sensor -> MEMS device -> semiconductor sensor -> electronic transducer. Absolute-pressure variants are preferred where the measurement must track a fixed reference rather than a moving one, which is critical for engine manifold absolute pressure (MAP) sensing, sealed-system leak testing, barometric corrections, and altitude calibration. Key features include a calibrated accuracy of approximately ±1.5% VFSS over 0 C to 85 C, on-chip signal conditioning that eliminates external compensation components, automotive-grade temperature endurance up to 125 C, and a robust ported SSOP-8 small outline package. The integrated bipolar op-amp front end and laser-trimmed thin-film resistor network remove the need for external op-amps or trim pots, simplifying PCB layout and shortening design cycles for high-volume automotive and industrial modules. The MPXH6300AC6U uses piezoresistive silicon strain gauges diffused into a diaphragm, with an on-chip bipolar op amp stage and ratiometric output relative to VCC. Ratiometricity means the output scales with the supply voltage, so a stable 5 V reference (or a well-decoupled 5 V rail) is required to preserve absolute accuracy; a drifting 5 V supply will directly scale the reading. The vacuum-referenced sealed die produces a true absolute measurement, eliminating barometric compensation in software. Typical applications include automotive manifold absolute pressure (MAP) sensing, HVAC pressure monitoring, industrial process control, barometric altimetry for drones and weather stations, and sealed-system leak detection. The wide 20-304 kPa range comfortably spans sub-atmospheric manifold vacuum (down to 20 kPa absolute) through turbocharged boost pressure (up to ~3 bar absolute). When designing with this part, hold the 5 V supply within ±5% and add 100 nF + 10 uF decoupling close to VCC and GND to preserve ratiometric accuracy and reject supply noise on the analog output.
MPXH6400AC6T1 - 20-400 kPa Absolute Pressure Sensor 8-SOIC | NXP
The NXP MPXH6400AC6T1 is a high-temperature-accuracy integrated silicon absolute pressure sensor measuring 20 kPa to 400 kPa (2.9 PSI to 58.02 PSI) with an analog 0.2 V to 4.8 V ratiometric output, housed in an 8-pin SOIC (8.50 mm width) package with a top-facing pressure port. The part integrates on-chip bipolar op-amp signal conditioning, temperature compensation, and factory calibration, and was originally developed by Freescale Semiconductor before NXP acquired the product line. An absolute pressure sensor is a transducer that measures pressure referenced to a sealed vacuum cavity rather than to ambient atmosphere, allowing the device to report absolute pressure regardless of weather, altitude, or local barometric conditions. Absolute pressure sensors belong to the broader category of piezoresistive silicon sensors -> MEMS pressure sensors -> pressure transducers -> sensor ICs, and they are widely used where altitude, vacuum, or sealed-system pressure must be measured directly. Key features include a calibrated output span of 4.6 V across 380 kPa, a typical full-scale output of 4.8 V at 400 kPa (5 V supply), a response time of approximately 1 ms, and an operating temperature range spanning -40 C to +125 C suitable for under-hood automotive and industrial environments. The integrated signal chain eliminates the need for external amplifiers, ADC drivers, or discrete temperature-compensation networks. The MPXH6400AC6T1 uses a piezoresistive Wheatstone-bridge sensing element fabricated with bipolar semiconductor processing, then co-integrated with a precision op-amp, bandgap reference, and calibration EEPROM-trimmed thin-film resistors. This monolithic architecture produces a ratiometric analog output that scales with supply voltage, simplifying ADC interfacing and immune to most supply-rail noise. Typical applications include engine manifold absolute pressure (MAP) sensing, barometric pressure measurement, weather stations, HVAC controllers, medical respiratory equipment, and industrial process monitoring. The high-temperature rating makes it especially suitable for under-hood automotive ECU applications. When designing with this sensor, place the device away from heat sources and use a 5 V regulated supply with a 0.1 uF decoupling capacitor close to the supply pin to filter noise. The output is ratiometric, so the ADC reference must be tied to the same supply to preserve accuracy across supply variations. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single reference for evaluation and sourcing.
MPXHZ6115A6T1 - 15-115 kPa Absolute Pressure Sensor | NXP | 8-SOIC

It measures absolute pressure from 15 kPa to 115 kPa (2.18 PSI to 16.68 PSI), translating that range into an analog output voltage of 0.2 V to 4.7 V at a 5 V supply. The device is housed in a surface-mount 8-SOIC (0.295", 7.50 mm width) package qualified for media-resistant, high-temperature environments. An absolute pressure sensor is a transducer that measures pressure relative to a sealed vacuum reference rather than to ambient atmosphere, making it ideal for applications requiring an absolute barometric reference such as altimetry, weather stations, and sealed system monitoring. The MPXHZ6115A6T1 belongs to the MPxx6115A family of integrated pressure sensors, sitting within the broader hierarchy of MEMS sensors -> pressure sensors -> environmental sensors -> semiconductor transducers. Its on-chip signal conditioning eliminates the need for external amplification or calibration circuitry on the PCB. Key differentiating features include ±1.5% accuracy (specified over the compensated temperature range of 0 °C to 85 °C), temperature compensation from -40 °C to +125 °C, and a maximum overpressure rating of 400 kPa (58.02 PSI). The integrated bipolar op-amp stage delivers a high-level, near-rail-to-rail analog output proportional to applied pressure, simplifying ADC interfacing on the host microcontroller. The MPXHZ6115A6T1 uses NXP's proprietary micromachined silicon strain-gauge bridge plus bipolar signal chain, with thin-film laser-trimmed resistor networks providing calibration and temperature compensation at the wafer level. This architecture yields repeatable, low-drift output across the specified pressure and temperature windows without requiring user-side software compensation. Typical applications include engine control manifold absolute pressure (MAP) sensing, barometric altitude measurement, weather stations, HVAC pressure monitoring, and sealed enclosure leak detection. The wide 5 V supply operation and ratiometric analog output allow direct connection to most microcontroller ADC inputs. When designing with the MPXHZ6115A6T1, provide adequate port venting if measuring ambient pressure and ensure the supply is well-decoupled with a 0.1 µF ceramic capacitor placed close to the supply pin. The ratiometric output means that ADC readings scale with supply voltage, so a stable, low-noise 5 V rail is essential for accurate pressure conversion. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found on the manufacturer datasheet, giving engineers a single decision-ready reference for selecting the MPXHZ6115A6T1 in new designs and drop-in replacements for legacy layouts.
MPXHZ6115A6U - 15-115 kPa Absolute Pressure Sensor | NXP
The NXP MPXHZ6115A6U is a monolithic, signal-conditioned, absolute-pressure silicon sensor integrating on-chip bipolar op-amp circuitry and thin-film resistor networks in an 8-pin SOP (8-SOIC, 7.50 mm width) package. It operates from a single 5 V supply, measures absolute pressure from 15 kPa to 115 kPa (2.18 psi to 16.68 psi), and outputs a calibrated analog voltage from 0.2 V to 4.7 V proportional to applied pressure. The MPXHZ6115A6U variant uses NXP's Media Resistant gel for high-humidity and common automotive media protection. An absolute pressure sensor is a transducer that measures pressure relative to a sealed internal vacuum reference rather than ambient atmospheric pressure. In the broader taxonomy, absolute pressure sensors fall under pressure sensors -> sensors -> signal-conditioning semiconductors. The internal vacuum reference means the output remains accurate regardless of ambient atmospheric changes, which is essential for altitude-sensing, sealed manifold absolute pressure (MAP) readings, barometric measurements, and any application where a stable vacuum baseline is required. Key features of the MPXHZ6115A6U include integrated temperature compensation from -40 °C to +125 °C, factory calibration for high accuracy across the operating range, and a ratiometric analog output that scales with supply voltage. The 8-SOIC surface-mount package (SOP 8) provides a robust molded carrier with an integrated pressure port, and the "U" suffix designates a Tube packing option. The HZ in the suffix indicates the high-impedance / Media Resistant gel variant, distinct from the MPXH6115A6U which uses standard Fluorosilicon gel. The architecture combines a micromachined silicon diaphragm, a Wheatstone-bridge piezoresistive strain gauge, on-chip bipolar amplification, and thin-film calibration resistors. The single-rail 5 V supply and 0.2-4.7 V output swing are designed to interface directly with an ADC input of an automotive ECU, industrial controller, or microcontroller without additional analog front-end components. Typical applications include automotive manifold absolute pressure (MAP) sensing, barometric/altitude measurement in portable GPS and weather stations, HVAC duct pressure monitoring, industrial pneumatic system monitoring, sealed enclosure integrity testing, medical respiratory equipment, and drone altitude hold systems. Designers frequently pair the MPXHZ6115A6U with a microcontroller's 5 V ADC input or an external 12-bit ADC front-end for digitizing the output. When designing with this part, place a 0.1 µF decoupling capacitor as close to the VCC pin as possible and ensure the pressure port is sealed against contamination with a properly rated elastomeric gasket. The Media Resistant gel variant tolerates moisture, oil, and automotive fluids, so it is preferred over the Fluorosilicon gel MPXH6115A6U when the sensor may contact fuel vapor or refrigerant. Note that the output is ratiometric - any change in VCC scales the output proportionally, so the ADC reference should be tied to the same 5 V rail for highest accuracy. This page synthesizes distributor pricing, drop-in alternatives from the same NXP MPXxx6115A family, and practical design notes that engineers need when sourcing an automotive-grade absolute-pressure sensor.
MPXHZ6115AC6T1 - 15-115kPa Absolute Pressure Sensor | NXP | SSOP-8
The NXP Semiconductors MPXHZ6115AC6T1 is a media-resistant, high-temperature-accuracy, monolithic, signal-conditioned silicon pressure sensor that 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 4.7 V from a 4.75 V to 5.25 V supply. The device is housed in an 8-pin SSOP (Super Small Outline Package) with an exposed top port that accepts a 3.3 mm (0.13 inch) tube and uses NXP's Media Resistant Gel over the sensing element to tolerate humid and harsh environments. A pressure sensor is a transducer that converts an applied gas or fluid pressure into an electrical signal. Absolute pressure sensors reference a sealed vacuum cavity, so the output reflects total pressure relative to that internal vacuum - making them ideal for barometric, altimetric, and sealed-system measurements. The MPXHZ6115AC6T1 belongs to the integrated silicon pressure sensor category, which combines a MEMS piezoresistive bridge with on-chip bipolar op-amp gain and thin-film calibration networks to produce a temperature-compensated, calibrated high-level signal that needs no external compensation circuitry. Key features include on-chip temperature compensation from -40 °C to +125 °C, maximum overpressure of 400 kPa (58.02 PSI), ratiometric 5 V supply operation, and the media-resistant gel that protects the die from condensation, dust, and corrosive vapors. The integrated op-amp stage delivers a nominal sensitivity of 45.9 mV/kPa while the on-chip thin-film network calibrates the offset and span across temperature. The internal architecture pairs a diffused piezoresistive strain-gauge bridge with a precision bipolar op-amp chain and laser-trimmed thin-film resistors. This single-chip integration eliminates the discrete instrumentation amplifier that legacy board-mount sensors require, simplifying PCB layout and improving noise immunity by keeping the high-impedance bridge signals on-chip. Typical applications include barometric pressure measurement for weather stations and altimeters, manifold absolute pressure (MAP) sensing in engine control units, medical respiratory monitoring, HVAC altitude compensation, and sealed-system pressure monitoring where the gel coating protects the die from condensing media. When designing with this device, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin and keep analog ground return paths short to minimize noise pickup on the high-impedance ratiometric output.

MPXHZ6115AC6U - 15-115kPa Absolute Pressure Sensor, 5V | NXP
The NXP MPXHZ6115AC6U is a monolithic, signal-conditioned, absolute-pressure silicon sensor housed in an 8-SOIC surface-mount package with a top-side 3.3 mm tube port. It measures absolute pressure from 15 kPa to 115 kPa (2.18-16.68 PSI), produces an analog output of 0.2 V to 4.7 V at 5 V supply, and is factory-calibrated with on-chip temperature compensation from -40 °C to +125 °C. A pressure sensor is a transducer that converts an applied gas or fluid pressure into a proportional electrical signal. Absolute-pressure sensors reference an internal sealed vacuum cavity, so the output reflects total pressure relative to perfect vacuum (as opposed to gauge or differential sensors, which reference ambient atmospheric pressure). The MPXHZ6115AC6U integrates bipolar op-amp signal conditioning and a thin-film resistor network on the same silicon die, eliminating the need for external amplification and compensation circuitry at the board level. Key features include a typical sensitivity of 45.9 mV/kPa, accuracy of ±1.5 % over the compensated temperature range, an operating supply of 4.75 V to 5.25 V, and a media-resistant PPS (polyphenylene sulfide) surface-mount package rated for high-temperature environments. The integrated temperature-compensation network flattens the output across -40 °C to +125 °C, so downstream firmware does not need to apply lookup-based linearization for typical barometric and manifold-absolute-pressure (MAP) readings. Architecturally, the device uses a piezoresistive MEMS strain-gauge bridge that is laser-trimmed and temperature-compensated at wafer level. The on-chip bipolar op-amp provides a low-impedance ratiometric output proportional to VCC, simplifying ADC sampling in microcontroller-based designs. Media-resistant gel covers the diaphragm, allowing use with non-corrosive air and dry gases. Typical applications include automotive manifold absolute pressure (MAP) sensing, barometric altimeters and weather stations, industrial pressure instrumentation, HVAC duct-pressure monitoring, and medical respiratory equipment. The 8-SOIC top-port package simplifies board mounting and tube attachment in space-constrained designs. When designing with this part, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin, and use a stable low-noise 5 V regulator to preserve ratiometric accuracy. Avoid exposing the port to condensing moisture or aggressive chemicals that the PPS-gel media barrier cannot tolerate.

MPXHZ6116A6T1 - 20-115kPa Absolute Pressure Sensor | NXP | SOIC-8
The NXP MPXHZ6116A6T1 is a monolithic, signal-conditioned, media-resistant integrated silicon pressure sensor that provides a calibrated absolute pressure output from 20 kPa to 115 kPa (2.9 PSI to 16.68 PSI). Housed in an 8-pin SOIC (7.50 mm body width) surface-mount package, the device combines an on-chip bipolar op-amp signal chain, thin-film metallization, and bipolar semiconductor processing to deliver a high-level analog output voltage of 0.399 V to 4.645 V proportional to applied absolute pressure. An absolute pressure sensor is a transducer which produces an output voltage referenced to an internal vacuum cavity rather than to ambient atmospheric pressure. Pressure sensors in this category belong to the broader MEMS and sensor hierarchy: pressure transducer -> piezoresistive sensor -> MEMS sensor -> semiconductor sensor -> electronic sensor. Absolute references are critical in applications that must distinguish barometric pressure altitude, sealed-cavity pressure, or any closed-volume measurement where the surrounding atmosphere cannot be used as the reference. Key features include on-chip temperature compensation over 0 C to 85 C, factory calibration that eliminates the need for external trimming, a 5 V nominal supply with low current draw, and media-resistant port versions for use with non-corrosive gases and lightweight fluids. The piezoresistive sensing element is fabricated using bulk-micromachined silicon and is electrically isolated from the media-side gel coating used to protect the diaphragm from contamination. The MPXHZ6116A6T1 architecture pairs a Wheatstone-bridge piezoresistive cell with a precision bipolar op-amp and laser-trimmed thin-film resistor network, providing temperature compensation from -40 C to +125 C operating range with calibrated accuracy typically better than 1.5 percent over the compensated range. The high-level 0.399 V to 4.645 V swing interfaces directly to microcontrollers with A/D inputs without additional gain stages, simplifying BOM and PCB layout. Typical applications include HVAC blower control, weather station barometry, altimeter instrumentation, medical respiratory monitoring, tire-pressure monitoring subsystems, sealed-system leak testing, and industrial process control where absolute pressure measurement is required. Design tip: place a 100 nF decoupling capacitor close to the VCC pin and route the analog output away from switching regulator and high-current traces to minimize conducted noise coupling into the sensor signal chain. Use the 5 V supply tolerance recommended by NXP to maintain calibrated accuracy.

MPXHZ6116A6U - 20-115 kPa Absolute Pressure Sensor | NXP
The NXP MPXHZ6116A6U is a media-resistant, on-chip signal-conditioned, temperature-compensated and calibrated absolute pressure sensor covering 20 kPa to 115 kPa (2.9 PSI to 16.68 PSI) in an 8-pin SSOP (SOP-8) surface-mount package. It delivers a ratiometric analog voltage output of 0.399 V to 4.645 V from a 5 V supply and integrates a bipolar op-amp network plus thin-film resistor calibration to remove external compensation components. A pressure sensor is a transducer that converts an applied gas or fluid pressure into a proportional electrical signal. Absolute pressure sensors, like the MPXHZ6116A6U, reference a sealed internal vacuum cavity so the output represents pressure relative to perfect vacuum rather than ambient atmosphere. This makes them well suited for sealed-system monitoring such as engine manifold absolute pressure (MAP), barometric correction, weather stations, sealed enclosures, and altitude estimation, where the absolute reference is required for accurate measurement. Within the broader sensor taxonomy, the device belongs to: pressure sensor -> piezoresistive/MEMS pressure transducer -> absolute pressure transducer -> environmental sensor IC. Key specifications include a 5.0 V typical supply (4.75 V to 5.25 V), ratiometric output of approximately 5% to 90% of VCC, ±1.5% (max) accuracy over 0 °C to 85 °C with temperature compensation from -40 °C to +125 °C, 1 ms settling time, and 6 mA typical supply current. The integrated bipolar op-amp stage and on-chip thin-film calibration network provide a calibrated, amplified signal without the need for external trim or compensation components. The MPXHZ6116A6U uses a piezoresistive MEMS strain gauge diffused into a silicon diaphragm; deflection under pressure changes the bridge resistance, which the on-chip amplifier then linearizes and temperature-compensates. The result is a near-linear voltage output that can be fed directly to a microcontroller ADC. The HZ series suffix denotes the highest-ruggedized media-resistant port geometry, allowing exposure to harsh environments. Typical applications include automotive manifold absolute pressure (MAP) sensing, HVAC pressure monitoring, weather stations, altitude measurement, industrial process control, and sealed-enclosure leak detection. The wide 5 V supply tolerance and ratiometric output simplify design with 5 V microcontrollers and ADC front ends. When designing with this part, note that the output is ratiometric to the supply voltage, so a clean, stable 5 V rail is essential for accurate readings. Decouple VCC with 0.1 µF ceramic + 1 nF noise-bypass capacitors placed close to the supply pin to prevent ADC conversion noise. Do not apply pressures beyond 400 kPa to avoid permanent damage to the silicon die. This page synthesizes distributor pricing, drop-in alternatives, parametric comparisons, and practical design notes not found in the manufacturer datasheet alone, helping engineers select, source, and implement the MPXHZ6116A6U with confidence.
MPXHZ6250AC6T1 - 20-250kPa Absolute Pressure Sensor | STMicroelectronics
The STMicroelectronics MPXHZ6250AC6T1 is a high-temperature-accuracy, integrated silicon pressure sensor that measures absolute pressure from 20 kPa to 250 kPa (2.9 to 36.26 PSI), housed in an 8-pin SOIC package with a top axial pressure port. It provides an analog output of 0.3 V to 4.9 V that is linearly proportional to applied pressure, with a sensitivity of approximately 20.4 mV/kPa and on-chip temperature compensation from -40 °C to +125 °C. According to the STMicroelectronics product page, the device integrates bipolar op-amp circuitry and thin-film resistor networks to deliver a high-level, calibrated analog output signal conditioned for direct microcontroller ADC input. What is an absolute pressure sensor? An absolute pressure sensor is a transducer that measures pressure relative to a perfect vacuum (zero reference), as opposed to gauge or differential sensors that measure relative to ambient or another port. Absolute pressure sensors are widely used in applications where a fixed vacuum reference is required - including barometric measurement, altimetry, weather stations, engine manifold absolute pressure (MAP) sensing, and sealed-system monitoring. Absolute pressure sensors sit within the broader hierarchy of pressure transducers -> MEMS sensors -> sensors -> electronic components. Key features include ±1.5 %FS accuracy, on-chip signal conditioning, calibrated and temperature-compensated output over the full -40 °C to +125 °C automotive range, and a media-resistant top-side port that accepts a 3.3 mm tube for pneumatic connection. The piezoresistive transducer element uses advanced micromachining and bipolar semiconductor processing for high reliability and stable long-term output. Supply voltage is nominally 5 V, and the ratiometric analog output simplifies ADC interfacing without precision voltage references. The architecture combines a monolithic silicon strain-gauge bridge with on-chip signal conditioning - including a precision bandgap reference, temperature compensation network, and output amplifier - so no external compensation components are required. This integrated approach achieves a calibrated, ratiometric output within ±1.5 %FS across the full pressure and temperature range, eliminating the need for end-of-line calibration in many applications. The exposed top-side port accepts standard 3.3 mm pneumatic tubing for direct media connection. Typical applications include manifold absolute pressure (MAP) sensing in automotive engine control units, barometric pressure measurement for weather stations and altimeters, industrial process control, HVAC pressure monitoring, and consumer appliance pressure sensing. The wide operating temperature range and high accuracy make the MPXHZ6250AC6T1 particularly suited for under-hood automotive and industrial environments. The top-port package simplifies manifold mounting compared to side-port alternatives. When designing with this device, ensure a stable 5 V supply and add a small RC filter on the output to suppress high-frequency noise from switching regulators and EMI sources in electrically noisy environments such as automotive engine bays. The ratiometric output means the supply voltage must be accurate or the output reading will scale proportionally with VCC.
MPXHZ6400A6T1 - 20-400kPa Absolute Pressure Sensor | NXP
The NXP MPXHZ6400A6T1 is an integrated silicon piezoresistive absolute pressure sensor with on-chip bipolar op-amp signal conditioning, temperature compensation, and factory calibration, housed in an 8-pin SSOP (Super Small Outline Package) with an axial port. It measures absolute pressure from 20 kPa to 400 kPa (2.9 PSI to 58.02 PSI) and provides a ratiometric analog output from 0.2 V to 4.8 V over a 4.64 V to 5.36 V supply range. An absolute pressure sensor is a transducer that measures pressure relative to a perfect vacuum rather than to ambient atmospheric pressure, making it ideal for sealed-system applications where the absolute reference must remain stable regardless of weather or altitude changes. Absolute pressure sensors belong to the broader family of MEMS (Micro-Electro-Mechanical Systems) pressure transducers, which sit within the sensor hierarchy of measurement semiconductors, and they are widely used where altitude, barometric, or sealed-cavity pressure must be quantified. Key features include ±1.5% accuracy over 0 °C to 85 °C, a temperature-compensated output spanning the full 20 kPa to 400 kPa range, media-resistant packaging tolerant of humid air and non-corrosive gases, and high electromagnetic immunity thanks to on-chip bipolar op-amp buffering. The integrated thin-film resistor network performs offset, span, and temperature calibration at the factory, eliminating the need for external compensation components. The sensor integrates a MEMS silicon diaphragm with a Wheatstone-bridge piezoresistor network. Differential strain on the diaphragm produces a differential bridge output that is amplified by the on-chip op-amp stage to the standard 0.2 V to 4.8 V full-scale ratiometric swing. Because the output is ratiometric to VCC, supply noise is rejected naturally and no precision voltage reference is required downstream. Typical applications include engine control manifold absolute pressure (MAP) sensing, barometric pressure measurement for weather stations and altimeters, HVAC system pressure monitoring, medical respiratory equipment, and industrial process control. Designers value the integrated calibration because it removes per-unit trimming during production and shortens time-to-market. When designing with this device, route the analog output through an RC low-pass filter (typically 1 kΩ and 100 nF) to attenuate high-frequency noise before the ADC input. The exposed axial port should be sealed with an O-ring and protected from liquid ingress, which can damage the MEMS element.

MPXHZ6400AC6T1 - 20-400kPa Absolute Pressure Sensor | NXP
The NXP MPXHZ6400AC6T1 is a media-resistant, high-temperature-accuracy integrated silicon absolute pressure sensor with on-chip bipolar op-amp signal conditioning, temperature compensation, and calibration. It measures absolute pressure from 20 kPa to 400 kPa (2.9 PSI to 58.02 PSI) and produces an analog output spanning 0.2 V to 4.8 V from a 5 V supply. It is housed in an 8-SSOP package with a top-facing pressure port and is shipped on tape-and-reel in 1,000-piece quantities. An absolute pressure sensor is a transducer that measures pressure referenced to a perfect vacuum rather than ambient atmosphere, making it ideal for sealed-system applications where the back side of the sensing element is evacuated and sealed. Within the sensor taxonomy, the MPXHZ6400AC6T1 sits in the integrated (signal-conditioned) absolute pressure sensor family, between raw piezoresistive MEMS cells (which require external amplification) and full digital I2C/SPI pressure modules (which integrate ADC and MCU on chip). It occupies the middle tier where the chip outputs a calibrated analog voltage but the application MCU still handles interpretation. Key features include a sensitivity of 12.1 mV/kPa, accuracy of plus/minus 1.5 percent full-scale span, and an operating temperature range of -40 C to +125 C. The integrated bipolar op-amp front end with thin-film resistor networks delivers a ratiometric output proportional to supply voltage, simplifying ADC interfacing. The top-port tubing interface accepts a 3.3 mm (0.13 inch) tube; the suffix C6 indicates the tube orientation. Technically, the device uses a single-port MEMS strain-gauge bridge that is laser-trimmed during manufacture. The on-chip conditioning corrects second-order temperature errors across the automotive-grade -40 C to +125 C range. Compared to the non-Z MPXH6400AC6T1, the Z suffix denotes media-resistant gel protection over the die for harsh media exposure. Typical applications include manifold absolute pressure (MAP) sensing in engine control units, industrial pneumatic monitoring, altimeter/barometric pressure modules, HVAC differential measurement, and motorcycle/small-engine fuel-pressure monitoring. The integrated calibration eliminates per-board trimming in production. Designers should treat the output as ratiometric with Vcc; if the ADC reference tracks Vcc, no extra calibration is required. Decouple Vcc with a 100 nF ceramic plus a 1 uF bulk capacitor placed within 5 mm of the supply pin to keep noise off the analog output stage.
MPXM2010D - 10kPa Differential Pressure Sensor | NXP
The NXP MPXM2010D is a 10 kPa differential piezoresistive silicon pressure sensor in a 5-SMD module package with on-chip temperature compensation and laser-trimmed calibration. According to the manufacturer datasheet, the device delivers a highly linear differential voltage output of 0 mV to 25 mV at 10 V excitation for a full-scale pressure of 1.45 PSI (10 kPa), with ±1% accuracy. The sensor operates from a single 10 V to 16 V supply and shares its monolithic silicon die with the MPX2010 and MPXV2010G family members. A piezoresistive pressure sensor is a transducer that converts an applied differential pressure into a proportional electrical output by exploiting the piezoresistive effect in doped silicon — when mechanical strain is applied to a diaphragm embedded with Wheatstone-bridge resistors, the resistance values shift predictably and unbalance the bridge. The monolithic silicon die integrates both the strain gauge and the thin-film resistor network, making the device a member of the transducer family within sensor signal-conditioning components used in industrial, medical, and HVAC systems. Key features of the MPXM2010D include on-chip temperature compensation from 0 °C to +85 °C, ratiometric output scaled to supply voltage for improved ADC accuracy, and ±1.5 % linearity over the pressure range. The 5-SMD module package includes the dual vertical-port tubing geometry that defines the 'M' (modular) variant of the MPX2010 family. The single-supply 10 V to 16 V operating range simplifies analog front-end design in 4 mA-to-20 mA loop-powered systems. Typical applications include medical inhalation therapy devices, HVAC variable-air-volume (VAV) controllers, industrial process control loops, level sensing in non-corrosive fluid reservoirs, and barometric calibration of digital altimeters. The differential port configuration enables bidirectional pressure measurement — a critical requirement in flow metering for medical ventilators where the drop across a flow element must be sensed. When designing with the device, place the part after a low-noise instrumentation amplifier and use a 16-bit ADC for full-scale resolution. The output is ratiometric to the supply — variations in excitation voltage will scale the output proportionally, so use a precision reference or well-regulated supply to maintain accuracy.

MPXM2010GS - 10kPa Vented Gauge Pressure Sensor | NXP/STMicro
The NXP MPXM2010GS is a 10 kPa (1.45 PSI) on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor packaged in a 5-SMD module with a top-port, male 0.12" (2.97 mm) tube inlet. The monolithic silicon diaphragm integrates a strain-gauge Wheatstone bridge plus a thin-film resistor network, laser-trimmed for precise span, offset, and temperature compensation. With a 10 V excitation the device delivers a linear differential output of 0 mV to 25 mV across the 0 to 10 kPa pressure range. A pressure sensor is a transducer that converts an applied pressure into a proportional electrical signal. Piezoresistive sensors, the family to which the MPXM2010GS belongs, exploit the change of silicon resistivity under mechanical strain. This class of sensor sits hierarchically below MEMS sensors and above general-purpose transducers in the sensor taxonomy, offering higher accuracy than ceramic capacitive cells but lower bandwidth than resonant or optical alternatives. Within pressure-sensor terminology, "vented gauge" means the back side of the diaphragm is open to ambient atmosphere through a vent port, so the output reflects differential pressure relative to local barometric conditions. The MPXM2010GS series provides nominal 2.5 mV/kPa sensitivity, very low pressure hysteresis, and excellent long-term stability over its -40 °C to +125 °C operating range. Its vented-gauge topology makes it especially attractive for applications that must reject package-stress and reference local atmospheric pressure. The uncompensated output voltage span remains consistent across temperature thanks to the on-chip thin-film compensation network, simplifying downstream signal conditioning. Typical applications include medical respiration monitors, HVAC air-flow measurement, weather-station barometric sensing, appliance pressure feedback, and industrial process control loops. The vented-gauge configuration with tube-port inlet suits enclosed module designs where reference-to-ambient accuracy matters more than fully-sealed absolute measurement. Designers should excite the bridge from a low-noise, low-drift 10 V reference and amplify the millivolt-level output with an instrumentation amplifier such as the INA128 or AD620. PCB layout should keep ground loops away from the sensor body, and the vent tube must remain unobstructed to preserve gauge accuracy.

MPXM2051GST1 - 50kPa Gauge Pressure Sensor, 5-SMD | NXP
The NXP MPXM2051GST1 is a silicon piezoresistive pressure sensor providing a linear voltage output directly proportional to the applied pressure, rated for 0 to 50 kPa (0 to 7.25 PSI) gauge measurement in a 5-SMD top-port module with a male 0.12" (2.97 mm) tube inlet. It delivers 0 mV to 40 mV output at a 10 V supply, with on-chip temperature compensation and calibration over 0 C to 85 C. A piezoresistive pressure sensor is a MEMS device in which a micromachined silicon diaphragm with embedded piezoresistive strain gauges converts mechanical pressure into a small differential voltage via the Wheatstone-bridge principle; within the sensor taxonomy it sits under MEMS pressure sensors -> pressure sensors -> sensors -> signal conditioning. This category of device is widely used where a precise, ratiometric analog pressure reading is needed without requiring an external front-end IC or ADC. Key differentiating features of the MPXM2051GST1 include on-chip temperature compensation and factory calibration, eliminating external compensation networks; a typical full-scale span of 40 mV at 10 V excitation (sensitivity ~0.8 mV/V); a maximum combined nonlinearity and pressure hysteresis of approximately ±0.4 %FSS (per the MPXM2051G datasheet); and a top-side tube port that simplifies pneumatic interface in manifold-style assemblies. The 5-SMD MPAK-4 (with tab) form factor suits surface-mount PCB assembly while preserving the through-port geometry. Technically, the device uses a monolithic silicon diaphragm with an integrated piezoresistive bridge. The differential output is a ratiometric analog voltage whose percentage deviation from nominal span closely tracks the percentage deviation of the input pressure from full scale. The vented-gauge reference allows barometric-pressure-compensated measurements in vented applications, which is critical for medical and HVAC equipment. Typical applications include medical respiratory instrumentation, HVAC air-flow monitoring, barometric correction for altitude-compensated devices, pneumatic control, and industrial process monitoring. The 50 kPa range suits low-pressure gas and air measurements in portable medical and HVAC equipment. When designing with this part, prefer a low-noise, regulated excitation source for the 10 V supply to maintain ratiometric accuracy; the bridge output is millivolt-level and requires a low-offset, low-noise instrumentation amplifier with adequate gain to feed an ADC. This page synthesizes drop-in alternatives, design notes, and FAQ content beyond the manufacturer datasheet to help engineers confidently select and integrate the MPXM2051GST1.

The NXP MPXM2053D is a 50 kPa on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor in a 5-SMD module (MPAK-style). It provides a highly accurate and linear differential voltage output directly proportional to applied pressure over a 0-50 kPa (0-7.25 PSI) range. The sensor is specified for 10 V typical excitation and delivers a nominal 0 mV to 40 mV full-scale span across the rated pressure. A piezoresistive pressure sensor is a MEMS device in which strain gauges diffused into a silicon diaphragm change resistance when the diaphragm flexes under differential pressure. The MPXM2053D integrates the strain-gauge bridge, a thin-film resistor network, and laser-trimmed calibration on a single monolithic die, yielding an analog millivolt output proportional to pressure without requiring external signal conditioning. Within the broader taxonomy, it sits as: pressure sensor -> MEMS sensor -> sensor -> electronic component. Related synonyms include piezoresistive transducer, strain-gauge pressure transducer, and Wheatstone-bridge pressure sensor. Key specifications include 0-50 kPa differential pressure range, 0-40 mV full-scale output at 10 V supply, 1.0 kohm typical bridge impedance, 0.25% linearity (typical for the MPX2053 family), and an operating temperature range of -40C to +125C. The on-chip temperature compensation and laser-trimmed offset/span calibration remove the need for external trimming in most applications. The 5-SMD module package supports through-hole-style port mounting with surface-mount lead forming. The MPXM2053D uses a single monolithic silicon diaphragm and integrated thin-film network that together produce a Wheatstone-bridge output. The bridge is laser-trimmed for span, offset, and temperature compensation, achieving stable millivolt-mV-per-kPa sensitivity over industrial temperature ranges. The chip-level calibration enables system designers to bypass per-board trimming while still meeting typical medical, industrial, and consumer accuracy targets. Typical applications include pump and motor control, robotics and end-effector force feedback, level detection in tanks, medical diagnostics (such as non-invasive blood pressure monitors and ventilators), HVAC pressure switching, and appliance water-level sensing. The differential topology makes it well suited to measuring gauge pressure relative to a reference port or to other chambers. Designers should evaluate the small mV-level output and add a low-offset, low-noise instrumentation amplifier (e.g. INA333 or equivalent) to drive an ADC. Proper PCB layout, port sealing, and isolation from package stress are critical because the SMD lead frame can transmit mechanical strain to the die.

MPXM2102A - 100kPa Absolute Pressure Sensor, 10V | NXP
The NXP MPXM2102A is a 100 kPa on-chip temperature-compensated silicon piezoresistive absolute pressure sensor in a 5-MPAK surface-mount module, delivering a linear Wheatstone-bridge output of 0 mV to 40 mV at a 10 V excitation. Operating range spans 0 kPa to 100 kPa (14.5 PSI absolute), with a maximum overpressure capability of 400 kPa (58.02 PSI). The transducer is housed in a 5-SMD (gull-wing) module with no port, suitable for board-mount pressure acquisition. An absolute pressure sensor is a transducer that generates an electronic signal as a direct function of the pressure imposed on its sensing diaphragm, referenced to a sealed internal vacuum cavity rather than ambient air. Piezoresistive sensors belong to the broader sensor hierarchy of MEMS devices -> semiconductor transducers -> signal-conditioning front-ends, and they are commonly paired with instrumentation amplifiers in the system signal chain. The MPXM2102A integrates on-chip temperature compensation, eliminating the need for external thermistor linearization in many embedded designs. Key features include a typical full-scale span of 40 mV at 10 V excitation, a 1.0 kOhm bridge impedance, ±0.1% linearity across the 0-100 kPa range, and a -40C to +125C operating temperature window with calibrated thermal behavior. The device operates from a 10 V DC nominal supply with low current draw, and its 5-MPAK module package provides easy PCB mounting alongside standard SMD components. The Wheatstone-bridge output enables direct interface to a differential ADC or op-amp front end. The MPXM2102A uses a monolithic silicon strain-gauge diaphragm die bonded inside the plastic 5-MPAK housing, with laser-trimmed resistors providing temperature compensation across the qualified range. Pressure applied to the front face deflects the diaphragm, changing the piezoresistor bridge balance and producing a differential millivolt signal proportional to absolute pressure. This analog output preserves native fidelity and lets designers choose their own amplification and filtering topology. Typical applications include medical spirometers and patient monitors, industrial process-control pressure transmitters, barometric altimeter reference designs, HVAC duct pressure sensing, and portable gas flow instrumentation. The 14.5 PSI absolute range suits body-pressure, weather-station, and low-pressure industrial use cases. When designing with the MPXM2102A, route the bridge excitation through a quiet, low-noise supply and place an instrumentation amplifier (such as an INA126 or AD620) within 20 mm of the output pins to minimize common-mode pickup. Use separate analog and digital grounds tied at a single star point near the ADC.

MPXM2102AS - 100kPa Absolute Pressure Sensor | NXP | Industrial
The NXP MPXM2102AS is a 100 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor that delivers a linear analog voltage output directly proportional to applied absolute pressure, housed in a 5-SMD module (top port) with a 0.12" (2.97 mm) tube inlet. A piezoresistive pressure sensor is a transducer that converts applied pressure into a proportional electrical signal by exploiting the piezoresistive effect of silicon — when mechanical strain is applied to a doped silicon resistor, its resistance changes predictably. In the bridge topology used here, four strain gauges form a Wheatstone bridge on a monolithic silicon diaphragm; an applied pressure deflects the diaphragm and unbalances the bridge, producing a differential output voltage that scales linearly with pressure. The on-chip thin-film resistor network calibrates and temperature-compensates this output, placing absolute-pressure sensing in the broader transducer hierarchy alongside gauge (relative) and differential pressure sensors. These sensors sit within the broader MEMS and sensor category used in industrial, medical, and HVAC equipment. Key features of the MPXM2102AS include an operating pressure range of 0 to 100 kPa (0 to 14.5 PSI absolute), a typical full-scale output of 40 mV at 10 V excitation, an offset of 0 mV, and a supply voltage of up to 10 V DC. The integrated calibration network provides temperature compensation across 0C to 85C, simplifying the analog front-end design by removing the need for external compensation circuitry. The 5-SMD top-port package accepts a 2.97 mm tube, allowing in-line pneumatic connection in sealed systems. Architecturally, the device uses a single monolithic silicon die with an integrated vacuum reference for absolute measurement. The piezoresistive bridge delivers a ratiometric output proportional to supply voltage, which simplifies ADC interfacing across varying supply rails. Typical non-linearity is in the low-percent range, and the calibration laser-trimmed resistor network standardizes part-to-part output across production lots, supporting system-level accuracy without per-unit trimming. Typical applications include barometric and weather-station instrumentation, medical respiratory equipment, altimeters and variometers, industrial process control, and HVAC duct pressure monitoring where 0-100 kPa absolute pressure conversion into a clean analog signal is required. When designing with this device, drive the input from a low-noise regulated supply to minimize excitation drift and add an instrumentation amplifier at the differential outputs for single-ended ADC conversion.

The STMicroelectronics MPXM2102AST1 is a 100 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor in a 5-pin M-PAK (MPAK) surface-mount module with a top axial port. It delivers a linear differential analog output of 0 mV to 40 mV at 10V excitation, with an absolute operating pressure range of 20 kPa to 100 kPa (14.5 PSI max) over the compensated 0 °C to +85 °C range. The sensor uses a single monolithic silicon diaphragm with on-chip strain gauge and thin-film resistor network, laser-trimmed for span, offset calibration, and temperature compensation. A piezoresistive pressure sensor converts applied force on a silicon diaphragm into a small resistance change in an embedded Wheatstone bridge; the resulting millivolt-level differential output is directly proportional to pressure. The MPX2102 series sits in the pressure sensor -> sensor -> transducer hierarchy used in industrial, medical, and consumer systems where a clean, temperature-stable analog pressure signal is required. Key features include 0 mV to 40 mV full-scale span (10V supply), 5.0 µV/V/kPa typical sensitivity offset, 1.0% max linearity error, and on-chip temperature compensation from 0 °C to +85 °C. The M-PAK 5-SMD module provides a single axial 0.12" (2.97 mm) tube port for vertical mounting, plus surface-mount gull-wing leads for PCB attachment and a tab for mechanical stability. The series draws ~6 mA from a 10V typical supply (16V max). The device is a silicon piezoresistive transducer in which the diaphragm strain gauge forms one leg of a Wheatstone bridge; laser-trimmed thin-film resistors null the bridge and calibrate the temperature coefficient, removing the need for external compensation networks. The four-active-lead M-PAK pinout plus grounded tab provides clean EMI behavior when the tab is soldered to a grounded copper pour. Typical applications include medical respiratory and patient monitoring, industrial process pressure measurement, HVAC transducers, altimeters/barometers, and portable barometric instruments. The absolute-pressure reference (vacuum sealed on the back side of the die) makes the device particularly suitable for barometric / weather-station use. The differential 0-40 mV output requires an external low-offset amplifier (e.g., instrumentation amp) for high-resolution ADC interfaces. Design tip: use a low-noise, low-offset instrumentation amplifier (such as TI INA122 or similar) to condition the 0-40 mV bridge output, route the analog traces over a continuous ground pour, and add 0.1 µF decoupling close to the supply pin to keep switching noise out of the bridge measurement.

It operates from a 10 V dc excitation supply and produces a linear, ratiometric analog voltage output directly proportional to applied pressure over a 0 to 100 kPa range. On-chip temperature compensation and calibration provide a span of approximately 40 mV at 10 V excitation, simplifying signal conditioning by allowing direct connection to an external ADC front-end. A piezoresistive pressure sensor is a MEMS device in which diffused strain gauges on a silicon diaphragm change resistance under applied pressure, generating a small differential voltage that is proportional to pressure. The MPXM2102A family belongs to the broader category of board-mount pressure sensors (sensor -> transducer -> MEMS -> semiconductor) used wherever a clean, linear, calibrated pressure signal is required without a discrete amplifier circuit. Key features include a 0 to 100 kPa operating pressure range (approximately 0 to 14.5 psi or 0 to 1 bar), ratiometric output for accuracy over supply variation, internal temperature compensation across 0 to 85 °C, and a robust single-element port (Sensor-5 case style) suitable for manifold mounting. The integrated signal-conditioning circuitry delivers a typical full-scale span of 40 mV at 10 V excitation, useful for low-noise instrumentation readouts. The MPXM2102A architecture uses an X-ducer strain gauge on a chemically-etched silicon diaphragm; the on-chip thin-film network performs offset, span and temperature calibration, eliminating external compensation resistors. The 10 V unipolar excitation is intentionally high to maximize output span and PSRR-style supply-noise rejection in industrial cabling environments. Typical applications include medical spirometers and patient monitors, HVAC air-flow monitoring, altimeters and barometric instruments, industrial pneumatic controls, and process-control analog front-ends. The Sensor-5 package provides a barbed pressure port for tube attachment in low-pressure gas-flow designs. When designing with this part, add a ratiometric ADC reference tied to the 5 V (or 10 V) excitation rail to preserve accuracy when supply tolerance drifts. Choose MPXM2102AST1 without the tape-and-reel trailer if your line is hand-loaded or you are prototyping with through-hole Sensor-5 sockets.

The NXP MPXM2102D is a silicon piezoresistive differential pressure sensor offering a 0 to 100 kPa (0 to 14.5 psi) measurement range with a linear analog voltage output of 0 mV to 40 mV at a 10 V supply. Housed in a 5-SMD M-PAK module, the device integrates on-chip temperature compensation and calibration, providing a stable, ratiometric output directly proportional to applied differential pressure. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a solid-state transducer that uses strain-induced resistance changes in a silicon diaphragm to convert applied pressure into a voltage. The sensor element itself is one tier in a broader transducer hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor IC. Piezoresistive sensors occupy the high-accuracy, low-pressure niche of this family, contrasted against capacitive (high sensitivity) and resonant (high stability) alternatives. They are widely used in medical and industrial applications where linearity, small size, and analog output simplicity outweigh the need for a digital interface. Key features include a full-scale output of 40 mV at 10 V excitation, a sensitivity of 0.4 mV/kPa, an operating temperature range of -40C to +125C, and a differential/gauge measurement topology with dual horizontal ports. The integrated temperature compensation covers 0 to 85C with a typical temperature coefficient of 0.5% FS, and the monolithic silicon diaphragm is laser-trimmed during calibration to minimize offset and span errors across the operating range. The MPXM2102D is built on NXP's mature MEMS process and a Wheatstone-bridge piezoresistive network diffused into the silicon diaphragm. The bridge excitation is ratiometric with the supply voltage, so the output scales linearly with Vex, enabling simple ADC conversion without a precision reference. The M-PAK 5-SMD module ports pressure horizontally through two opposed inlets, simplifying plumbing on both sides of a manifold or flow channel. Typical applications include medical respiratory monitoring (spirometers, ventilators), HVAC differential pressure sensing, industrial process control, gas flow measurement, and altimeter/barometer modules. The differential topology is well suited to measuring pressure drop across a flow element or the positive/negative pressure swing in a pneumatic actuator. When designing with this device, decouple the Vex supply with a 0.1 uF ceramic capacitor placed as close as possible to pins 2 and 4, and ensure the bridge output is conditioned by a low-offset, low-noise instrumentation amplifier such as the INA128 or MPX2010 to drive an ADC. Avoid mechanically stressing the M-PAK housing or the ports, as package strain couples directly into the diaphragm and degrades accuracy.

According to NXP product information, the device outputs 0 mV to 40 mV at 10 V excitation over a 0 to 100 kPa pressure range, delivering a linear response suitable for direct ADC conversion after instrumentation amplification. A piezoresistive pressure sensor is a solid-state transducer in which strain gauges diffused into a silicon diaphragm change resistance when the diaphragm flexes under pressure; the resulting Wheatstone bridge produces a differential voltage proportional to pressure. Piezoresistive pressure sensors sit in the transducer hierarchy: pressure sensor -> MEMS sensor -> sensor -> discrete semiconductor, and serve as the front-end element in medical, HVAC, and industrial instrumentation. Key features of the MPXM2102GS include on-chip temperature compensation and calibration via laser-trimmed thin-film resistors, providing span and offset accuracy that minimizes external calibration circuitry.

Typical applications include barometric and altitude measurement for weather monitoring stations, medical spirometers and non-invasive blood pressure monitors, HVAC differential pressure sensing, and industrial process control loops requiring accurate low-pressure measurement. The vented-gauge reference (port exposed to atmosphere through the package vent) makes the device ideal for applications where the measurement differential versus ambient pressure is the quantity of interest. When designing with the MPXM2102GS, use an instrumentation amplifier such as INA333 or AD620 to amplify the millivolt-level output to a 0-5 V or 4-20 mA range; provide a stable low-noise 10 V excitation; and add adequate filtering on the supply to reject EMI.

MPXM2202A - 200kPa Absolute Pressure Sensor 5-SMD | NXP/ST
The NXP MPXM2202A is a 200 kPa (29.01 PSI) absolute pressure sensor in a 5-SMD module package with on-chip temperature compensation and calibration, providing a linear analog voltage output proportional to applied pressure. The device integrates a monolithic silicon diaphragm with strain-gauge piezoresistors and a thin-film resistor network, laser-trimmed for span, offset, and temperature compensation between 0°C and +85°C. The output spans 0 mV to 40 mV at 10V excitation over the 0 kPa to 200 kPa range. A piezoresistive pressure sensor converts mechanical pressure into an electrical signal by exploiting the piezoresistive effect in silicon: when strain gauges on a flexing diaphragm change resistance, a Wheatstone bridge produces a differential voltage proportional to applied pressure. Absolute-pressure variants like the MPXM2202A reference a sealed vacuum cavity on-chip, so output is referenced to absolute zero pressure rather than ambient. This category sits within the broader sensor hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor IC -> semiconductor. Key features include 0°C to +85°C calibrated temperature range, 0 mV to 40 mV full-scale span at 10V supply, 0 to 200 kPa operating range, on-chip temperature compensation, and a small surface-mount 5-SMD module. The integrated compensation removes the need for external calibration circuitry, simplifying analog front-end design. The MPXM2202A uses a single monolithic silicon die containing the sensing diaphragm and the signal-conditioning thin-film network. Laser trimming during manufacture corrects both span and offset errors, while the on-chip temperature-compensation network minimizes thermal drift across the calibrated band. This architecture yields a robust analog output suitable for direct connection to instrumentation amplifiers or microcontroller ADCs. Typical applications include medical instrumentation (respiratory monitors, infusion pumps), industrial pressure monitoring, HVAC transducers, altimeters and barometric systems, and process-control loops where a calibrated analog pressure signal is required. The 0-40 mV span suits low-noise instrumentation amplifier front-ends. When designing with this sensor, ensure a clean, low-noise 10V excitation supply because output span scales linearly with supply. Add a low-offset, low-noise instrumentation amplifier (e.g. INA128) to amplify the 0-40 mV signal to a useful ADC range, and apply proper bypass/decoupling at the supply pins.

MPXM2202AS - 200 kPa Absolute Pressure Sensor, M-PAC | NXP
The NXP MPXM2202AS is a 200 kPa on-chip temperature-compensated silicon piezoresistive pressure sensor supplied in a 5-pin M-PAC top-port SMD module. It provides a differential analog output of 0 mV to 40 mV at 10 V excitation, sampling absolute pressure from 0 kPa to 200 kPa (0-29.01 PSI) through a 0.12" (2.97 mm) tube port. According to the NXP product listing, the device is packed in TUBE-TUBE MULTIPLE NDP with a minimum package quantity of 60 and minimum order quantity of 1200, at a budgetary price of $5.86 USD per 1k units. A piezoresistive pressure sensor is a micro-electro-mechanical (MEMS) device in which a silicon diaphragm with diffused strain gauges converts applied pressure into a proportional change in resistance. The MPXM2202AS integrates the sensing die, on-chip temperature compensation network, and signal-conditioning resistors in a single surface-mount module, allowing direct interface to an external ADC or instrumentation amplifier. Within the broader sensor taxonomy, it sits as: pressure sensor -> MEMS sensor -> transducer -> sensor IC -> semiconductor. The MPX2202/MPXM2202 family is the legacy industrial/medical successor to the original Motorola MPX2000 series piezoresistive cells. Key features include 0 mV to 40 mV full-scale output (typ. 0.2 mV/kPa sensitivity), 10 V typical excitation, on-chip temperature compensation across 0C to 85C, and an absolute pressure reference sealed inside the package. The 5-pin M-PAC package simplifies PCB layout compared to the larger unibody MPX2202GP variant, while preserving the same Wheatstone-bridge pinout. The sensor is intended for clean, dry, non-corrosive gases. The MPXM2202AS relies on a single-axial piezoresistive bridge: four ion-implanted resistors on a silicon diaphragm form a Wheatstone configuration, balancing at 0 kPa and unbalancing linearly with applied pressure. The on-chip compensation network cancels the first-order temperature coefficient of the bridge, allowing raw mV output to be read directly with reasonable accuracy over the 0-85C range. Typical applications include medical inhalers and patient monitors, HVAC pressure transmitters, altimeters and barometric instruments, industrial process control, and pneumatic system monitoring. For battery-powered designs, consider newer I2C/SPI digital sensors such as the NXP MPL3115A2 or the Bosch BMP280; the MPXM2202AS is best suited to systems that already have a stable 10 V analog supply and an ADC front end. When designing with this part, route the high-impedance bridge outputs on a guard trace or shield and place the ADC sample-and-hold within 50 mm of the output pins. Apply the 10 V excitation through a low-noise LDO such as the TPS7A4701 to avoid bridge self-heating drift.
