MPXAZ6115AP - 15-115 kPa Absolute Pressure Sensor, Side Port | NXP
The NXP MPXAZ6115AP is a monolithic, signal-conditioned silicon piezoresistive absolute pressure sensor covering 15 kPa to 115 kPa (2.18 PSI to 16.68 PSI), housed in an 8-pin SOP (Case 98ASB14767) surface-mount package with a side-mounted tube port and 0.2 V to 4.7 V ratiometric analog output. The on-chip bipolar op-amp circuitry and thin-film resistor networks provide temperature compensation from -40 C to +125 C, plus calibration that yields a typical accuracy of +/-1.5% over the compensated range. A pressure sensor is a transducer that converts an applied pneumatic or hydraulic pressure into a proportional electrical signal. In the broader system taxonomy it sits at the sensing layer: physical stimulus -> transducer -> signal conditioning -> ADC/MCU -> display or control bus. Absolute pressure sensors specifically measure pressure referenced to a sealed vacuum cavity rather than ambient atmosphere, making them the correct topology for barometric altitude, sealed-cavity pressure, and vacuum-relative measurements. Key features of the MPXAZ6115AP include a 5 V nominal supply (4.75 V to 5.25 V), 0.2 V to 4.7 V near-ratiometric output swing, on-chip temperature compensation, +/-1.5% accuracy, and a media-resistant PPS thermoplastic package qualified for harsh-environment mounting. The integrated op-amp front-end eliminates the external instrumentation amplifier that discrete bridge sensors require, reducing BOM cost and PCB area. Technically, the device uses a monolithic silicon strain-gauge bridge diffused into a diaphragm that deflects proportionally to applied pressure. The thin-film laser-trimmed resistor network compensates span, offset, and thermal drift across -40 C to +125 C, producing an output that designers can route directly to an ADC without further analog conditioning. Typical applications include barometric altimeters and weather stations, HVAC pressure monitoring, industrial process control, sealed-cavity leak detection, avionics altitude reference, and medical respiratory instrumentation. The side-port tube geometry suits vertical-mount manifolds and wall-mounted enclosures where a horizontal port would not align with the pressure inlet. When designing with this part, place a 100 nF decoupling capacitor close to VCC and route the analog output trace away from switching nodes to preserve the 1.5% accuracy budget. Confirm that the side-port tube dimensions (0.13 in / 3.17 mm OD) match the system manifold interface, and add a silicone-gasket seal if the media contains moisture or particulates.

MPXAZ6115APT1 - 15-115kPa Absolute Pressure Sensor | NXP
The NXP MPXAZ6115APT1 is an integrated silicon pressure sensor that measures absolute pressure from 15 kPa to 115 kPa (2.18 PSI to 16.68 PSI) and provides a temperature-compensated analog output of 0.2 V to 4.7 V from a single 5 V supply. Housed in an 8-pin SMD gull-wing package with a side-mounted male tube port (0.13 inch / 3.17 mm), the device combines a piezo-resistive strain-gauge bridge, on-chip signal conditioning, calibration, and temperature compensation in one molded media-resistant module. An integrated absolute pressure sensor is a transducer that converts applied pressure into a linear analog voltage proportional to the difference between the sensed pressure and a sealed internal vacuum reference. Unlike gauge sensors that vent to atmosphere, absolute sensors embed a fixed vacuum cavity so the output reflects total pressure at the port. In the broader sensor hierarchy, this device sits at the intersection of MEMS transducers and analog signal-chain components, providing a calibrated interface between physical media and downstream ADCs, microcontrollers, or displays without requiring external compensation circuitry. Key features include a 4.7 V full-scale output (typical 4.5 V nominal, maximum 4.8 V per device characterization), on-chip temperature compensation from -40 C to +125 C, media-resistant port construction suitable for non-corrosive gases, and an accuracy band adequate for consumer and industrial barometric applications. The 5 V single-supply operation simplifies interface to 5 V ADCs and standard MCU analog front-ends. The trimmed offset and span calibrations eliminate the need for external potentiometers in most designs. The device uses a patented silicon strain-gauge MEMS bridge coupled to a bipolar signal-conditioning ASIC. The bridge output is amplified, offset-trimmed, span-normalized, and temperature-compensated entirely on-chip, which removes the long calibration procedure typical of raw die pressure sensors. The SMD gull-wing package isolates the sensing die from PCB stress and provides repeatable thermal contact with the surrounding package mass. Typical applications include altimeters and barometric pressure measurement in portable GPS, weather stations, HVAC control loops, tire-pressure monitoring accessories, and industrial pneumatic system monitoring. The absolute reference makes it well-suited to altitude computation, where atmospheric pressure at sea level serves as the anchor. When designing with the MPXAZ6115APT1, place the device away from PCB flex points and avoid mechanical stress on the side port to preserve calibration accuracy. Add a small RC filter at the output to attenuate EMI in industrial installations, and provide adequate clearance around the port for tubing attachments.

MPXC2011DT1 - 10kPa Differential Pressure Sensor 4-SSIP | NXP
The NXP MPXC2011DT1 is a differential piezoresistive pressure sensor rated for 0 to 10 kPa (1.45 PSI) full-scale span in a 4-SSIP side-port Chip Pak module. It delivers a nominal 25 mV full-scale output (typical 2.5 mV/kPa sensitivity) at 10 V excitation and is temperature-compensated over 0 °C to 85 °C. A pressure sensor is a transducer that converts an applied pneumatic or hydraulic force into an electrical signal, and the differential subclass measures the pressure difference between two ports rather than against atmosphere. The MPXC2011DT1 sits in the broader hierarchy of MEMS sensors > pressure sensors > piezoresistive differential sensors > low-pressure signal-chain ICs, commonly paired with instrumentation amplifiers in medical, HVAC, and analytical-instrument front ends. Key features include on-chip temperature compensation and calibration, a piezoresistive Wheatstone-bridge strain gauge fabricated on a silicon diaphragm, a 4-SSIP single inline through-hole module with an integrated side-port pressure inlet, and 0 to 10 kPa operating range matched to respiratory and air-flow measurement applications. The 4-SSIP Chip Pak provides a small 7.6 mm x 12.8 mm footprint with barbed side-port hose connection. The device uses Freescale/NXP's piezoresistive silicon technology in which four ion-implanted resistors arranged in a Wheatstone bridge change resistance proportionally to diaphragm strain. The bridge is laser-trimmed during manufacture so that span, offset, and temperature coefficient are calibrated, allowing direct interface to a low-noise differential amplifier without per-unit compensation. Typical applications include medical respiratory monitoring (spirometry, ventilators), HVAC variable-air-volume boxes, industrial process control, analytical instruments, and portable low-pressure measurement. The differential configuration makes it particularly suitable for flow sensing across orifice plates, where the pressure drop is on the order of a few kPa. When designing with this device, plan for amplification because the 25 mV full-scale output is too small for direct ADC connection - typically a fixed-gain instrumentation amplifier with a gain of 40 to 160 is placed immediately after the sensor. The sensor output is ratiometric to the excitation voltage, so a clean, low-noise 5 V or 10 V reference is required for absolute accuracy. This page consolidates distributor pricing, pin-compatible alternatives, and practical signal-chain design guidance that goes beyond the manufacturer datasheet's basic specifications.
MPXC2012DT1 - 10 kPa Differential Pressure Sensor, 4-SSIP | NXP
The NXP MPXC2012DT1 is a 10 kPa (1.45 PSI) differential piezoresistive silicon pressure sensor in a 4-SSIP side-port module, delivering a full-scale output of 24 mV to 26 mV at 10 V excitation in a low-cost uncompensated chip-pak package without gel protection. This legacy Motorola/Freescale/NXP part is aimed at high-volume, low-pressure differential measurement applications where the host MCU performs amplification, temperature compensation, and calibration. A pressure sensor is a transducer that converts an applied pressure differential into a proportional electrical signal. The MPXC series uses a silicon diaphragm with piezoresistive strain gauges arranged in a Wheatstone bridge; when pressure is applied, the diaphragm flexes and the bridge becomes unbalanced, producing a millivolt-level output proportional to differential pressure. The uncompensated nature of the MPXC2012DT1 means the host system must linearize and temperature-compensate the raw mV signal. Key features include a 0 mV to 25 mV output span at 10 V excitation, a 0.128 inch (3.25 mm) female pressure port oriented to the side of the package, and a unidirectional differential pressure mode (positive on the front side). The 4-SSIP through-hole module mounts vertically on a PCB and accepts standard tubing via the integrated port, simplifying plumbing for airflow and liquid-level designs. Technically, the device uses a monolithic silicon strain-gauge bridge with laser-trimmed resistors for tight offset tolerance. The die-side bond wires and port geometry are optimized for low-pressure HVAC and medical-respiration airflow paths. Designers must provide a high-impedance instrumentation amplifier with low-noise gain (typically 100x) and software temperature compensation to achieve accurate absolute readings. Typical applications include HVAC differential pressure sensing, medical respiration/airflow monitoring, altimeters and barometric helpers, level detection, and industrial process control. The MPXC2012DT1 is well suited for cost-sensitive airflow measurement where the system can absorb a discrete op-amp and calibration step. When designing, route the high-impedance bridge output traces away from switching noise sources and provide a Kelvin connection to the excitation source. Without gel protection, do not expose the die-side cavity to condensing humidity or direct water contact; mount the port facing away from dust streams. This page consolidates distributor pricing, drop-in same-package alternatives, and practical design notes that go beyond the legacy datasheet.

The integrated bipolar op-amp front end and thin-film resistor network give a typical sensitivity of 45.9 mV/kPa with a maximum error of 1.5 % over the compensated temperature window. An absolute pressure sensor is a transducer that produces an output proportional to pressure referenced to a sealed vacuum cavity rather than ambient air. The MPXH6115A6U sits inside the broader sensor taxonomy as a piezoresistive silicon sensor -> MEMS pressure sensor -> absolute pressure transducer. Because the vacuum reference is built in, the device outputs a pressure reading that includes the local atmospheric component, which is ideal for sealed-cavity applications where atmospheric drift must be inherently rejected. Key features include a maximum pressure rating of 400 kPa (over-pressure survival to roughly 3.5x the full-scale operating range), ratiometric analog output that tracks VCC for ADC-friendly interfaces, and a typical current consumption of 6 mA. The SOIC-8 package with a top-side pressure port enables standard surface-mount reflow while preserving access for hose attachment, and NXP/Freescale screening to AEC-Q100-style flow supports automotive under-hood deployments.

Typical uses include automotive manifold absolute pressure (MAP) sensing, HVAC altitude compensation, weather-station barometric instruments, and medical respiratory equipment. Industrial applications include sealed-system leak detection, altitude reporting for drones, and process-control back-pressure monitoring where the 15-115 kPa window closely matches sea-level ambient. When designing with this part, place the 0.2-4.7 V output through an RC low-pass filter (typically 1 kohm/100 nF, fc ~ 1.6 kHz) before the ADC to suppress high-frequency noise from the supply pump. Use an ADC reference tied to VCC if ratiometric cancellation of supply variation is desired, since the output nominally scales with VCC.
MPXH6115AC6T1 - 15-115 kPa Absolute Pressure Sensor | STMicroelectronics
The STMicroelectronics MPXH6115AC6T1 is a high-temperature accuracy, monolithic, signal-conditioned silicon absolute pressure sensor integrating on-chip bipolar op-amp circuitry and thin-film resistor networks. It operates from 15 kPa to 115 kPa (2.18 to 16.68 PSI) absolute pressure with an analog output span of 0.2 V to 4.7 V at a 5 V supply, and is housed in a surface-mount 8-SSOP (0.335", 8.50 mm width) package with a top-side male 0.13" (3.3 mm) pressure port. An absolute pressure sensor measures pressure referenced to a sealed vacuum rather than ambient atmosphere, which is critical for applications requiring altitude determination, sealed-cavity monitoring, or barometric reference. The MPXxx6115A family occupies a defined tier in the broader sensor hierarchy: pressure sensor -> MEMS sensor -> signal-conditioned sensor -> environmental sensor -> semiconductor. On-chip temperature compensation is implemented from -40 C to +125 C, eliminating the need for external lookup tables or calibration in most embedded designs. Key features of the MPXH6115AC6T1 include 1.5% maximum accuracy across the compensated range, a durable thermoplastic (PPS) surface-mount package rated for high-temperature reflow, and a typical supply current under 10 mA from a single 5 V rail. The integrated op-amp and resistor network provide ratiometric output proportional to VCC, simplifying ADC interfacing without additional signal conditioning. Architecturally, the device combines a piezoresistive MEMS strain-gauge bridge with bipolar signal-conditioning silicon on the same die. This single-chip integration improves noise immunity and long-term drift compared with discrete bridge-plus-amplifier solutions. The ratiometric output simplifies MCU sampling because the ADC reference can share the sensor supply. Typical applications include engine manifold absolute pressure (MAP) sensing, barometric altimeters, weather stations, HVAC duct pressure monitoring, medical respiratory equipment, and tire pressure monitoring modules. The wide compensated temperature range and surface-mount form factor make it well suited for automotive under-hood and industrial environments. A primary design consideration is ratiometric ADC sampling: the sensor output scales linearly with VCC, so the microcontroller ADC reference must be derived from the same 5 V rail to preserve absolute accuracy. Decoupling VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin minimizes switching noise on the analog output.

Key features include on-chip bipolar op-amp signal conditioning, thin-film resistor network for temperature compensation across 0 C to +85 C, a typical sensitivity of 45.9 mV/kPa, and 5 V supply operation with 4.75 V to 5.25 V tolerance; the operation runs from -40 C to +125 C and the SOIC-8 package allows standard surface-mount assembly with the port integrated into the top of the body, eliminating the need for external tubing adapters. The MPXH6115AC6U uses piezoresistive MEMS silicon micromachining combined with bipolar op-amp circuitry to provide a high-output, temperature-compensated signal without requiring external amplification; the integrated bandgap reference and laser-trimmed resistors eliminate the need for software calibration in many applications, which simplifies firmware development. Typical applications include automotive engine control units (MAP sensing), barometric altitude measurement for GPS-augmented navigation, weather stations, altimeters, and HVAC pressure monitoring; the wide operating temperature makes it particularly suited to under-hood automotive environments. Designers should ensure the supply is regulated to 5 V +/- 5% and that an RC low-pass filter is added on the output if the ADC sampling rate introduces aliasing of high-frequency pressure transients. The tube port orientation must be sealed against moisture and debris in field installations.

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

MPXH6250A6U - 20-250kPa Absolute Pressure Sensor, 8-SOIC | NXP
The NXP MPXH6250A6U is a high-temperature-accuracy integrated silicon absolute pressure sensor designed for measuring absolute pressure from 20 kPa to 250 kPa (2.9 PSI to 36.26 PSI), housed in an 8-pin SOIC surface-mount package. The device integrates on-chip bipolar op-amp circuitry, thin-film resistor networks, and factory calibration to deliver a ratiometric analog output spanning approximately 0.3 V to 4.9 V from a 5.0 V supply, with a nominal sensitivity of 20.4 mV/kPa. What is an absolute pressure sensor? An absolute pressure sensor is a transducer which generates an electronic signal proportional to pressure measured relative to a sealed internal vacuum reference rather than ambient air. Absolute pressure sensors belong to the broader category of MEMS-based piezoresistive sensors and signal-conditioned pressure transducers, themselves a subclass of physical-environment sensors used in industrial, automotive, and medical instrumentation. They are differentiated from gauge pressure sensors (which reference atmosphere) and differential pressure sensors (which compare two ports). Key features include factory calibration over the 0 to 85 °C range, internal temperature compensation implemented in the on-chip bipolar op-amp and thin-film network, and ratiometric output that tracks the supply voltage for use directly with an analog-to-digital converter (ADC) referenced to the same rail. The integrated signal path eliminates the need for external signal conditioning in most applications. The MPXH6250A6U is built on a silicon piezoresistive strain-gauge bridge whose resistance changes with applied pressure. On-chip signal conditioning converts the small bridge differential to a buffered, temperature-compensated analog voltage. This architecture provides excellent noise immunity, fast response, and repeatable performance across the full operating range, while the SOIC-8 surface-mount package supports high-volume automated PCB assembly. Typical applications include manifold absolute pressure (MAP) sensing in fuel-injected and small engines, industrial process control, HVAC pressure monitoring, altimeter/barometric measurement, and consumer appliances requiring absolute pressure feedback. Its ratiometric analog output is well suited to direct connection to an automotive ECU or microcontroller ADC integrated in digital systems. When designing with this device, ensure a clean, regulated 5.0 V supply to maintain ratiometric accuracy, place decoupling capacitors close to the supply pin, and follow the port orientation specified for the A6U top-port SOIC package. For this configuration, do not exceed the rated pressure or temperature limits, otherwise the calibrated bridge network may be permanently damaged. The MPXH6250A6U is not a drop-in upgrade to the MPXH6300A6U family because the pressure range and sensitivity differ; use the family variant appropriate to your maximum system pressure.

Within the broader sensor taxonomy it sits under piezoresistive silicon pressure sensors -> pressure sensors -> transducers -> MEMS -> sensors. Absolute variants are differentiated from gauge (relative-to-atmosphere) and differential sensors and are used where the system must operate regardless of barometric drift - intake manifold, barometric altimetry, sealed enclosures and vacuum process control. Key electrical characteristics include a 5.0 V typical supply (operating within the broader 4.75 V to 5.25 V range commonly used with 5 V ratiometric ADCs), a 1 ms typical response time suitable for closed-loop control loops, an operating temperature range of -40C to +125C matching harsh under-hood and industrial environments, and a top-port pressure inlet that simplifies hose integration. The transfer function is approximately Vout = 5.0 V * (0.0038 * P_kPa + 0.058) for accurate MCU-side conversion. The integrated 8-bit-trimmed calibration yields typical accuracy around 1.5% to 2.5% over the compensated range. Technically, the device combines a MEMS piezoresistive Wheatstone bridge with a CMOS signal-conditioning ASIC on the same silicon carrier. Temperature compensation is performed by on-chip thin-film resistors laser-trimmed at wafer level, which keeps calibration drift low and removes the cost of per-unit trimming. The 0.3 V to 4.9 V swing maps cleanly onto a 5 V ADC full scale, maximizing ADC dynamic range without external gain. Typical applications include automotive engine control (MAP sensing, EGR monitoring), HVAC blower and filter diagnostics, barometric altitude and weather instruments, industrial process monitoring, medical respiratory equipment and sealed-enclosure leak detection. In each case the sensor substitutes for a discrete amplified bridge circuit at a fraction of the design effort. When designing with this part, place 100 nF decoupling close to the supply pin and drive the analog output through a low-impedance buffer or directly into an ADC with a high-impedance input. The top-side tube port should be sealed with an O-ring and protected against moisture and contamination, and the hose should be sized to avoid pressure drops across the full flow range.

MPXH6250AC6U - 20-250kPa Absolute Pressure Sensor, 8-SSOP | NXP
The NXP Semiconductors MPXH6250AC6U is a high-temperature-accuracy integrated silicon absolute pressure sensor with a 20 kPa to 250 kPa operating range, on-chip signal conditioning, temperature compensation, and calibration, housed in an 8-pin SSOP (case 1737) package with a top axial port. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a micromachined silicon die whose bridge resistance changes proportionally to applied pressure, producing a differential voltage that is then amplified, temperature-compensated, and calibrated on-chip to deliver a high-level analog output. The MPXH6250AC6U belongs to the integrated pressure sensor family within the broader board-mount sensor hierarchy (pressure sensor -> MEMS sensor -> transducer), combining MEMS micromachining, thin-film metallization, and bipolar op-amp circuitry in a single monolithic die. Key features include 0.3 V to 4.9 V ratiometric analog output (5 V supply), 20.4 mV/kPa typical sensitivity, ±1.5% maximum pressure error over 0 °C to 85 °C, AEC-Q100 qualification for under-hood automotive applications, and on-chip temperature compensation from -40 °C to +125 °C. The single 5 V supply simplifies power design, while the ratiometric output enables direct ADC interfacing without precision references. The MPXH6250AC6U employs a monolithic piezoresistive bridge whose differential output is amplified by an on-chip bipolar op-amp stage. Thin-film laser-trimmed resistor networks set the offset (0.20 V at 0 kPa), full-scale span, and temperature compensation coefficients, eliminating the need for external calibration components. The integrated construction provides EMI/RFI hardening, ESD protection to 2 kV HBM, and stable behavior across automotive temperature profiles. Typical applications include engine control manifold absolute pressure (MAP) sensing, barometric pressure measurement for engine management, HVAC blower control, weather station instrumentation, and industrial process monitoring. The top axial port with 0.13" (3.3 mm) tube stub allows direct pneumatic connection to manifold or vent references. Design consideration: provide a clean, well-decoupled 5.0 V ±0.25 V supply and configure the host ADC for the 0.3 V to 4.9 V swing. Avoid mechanical stress on the SSOP body that could shift the offset; mount with the port vertically oriented and isolate vibration sources.

MPXH6300A6U - 20-304kPa Absolute Pressure Sensor | STMicroelectronics
The STMicroelectronics MPXH6300A6U is a high-temperature, on-chip signal-conditioned, absolute pressure sensor integrated in an 8-pin SSOP (SOIC-8 wide-body) package. It measures absolute pressure from 20 kPa to 304 kPa (approximately 2.9 PSI to 44.09 PSI) and provides a temperature-compensated analog output of 0.3 V to 4.9 V ratiometric to a 5.0 V supply, giving roughly 16.2 mV/kPa sensitivity across the calibrated range. An absolute pressure sensor is a MEMS device that produces an output proportional to pressure referenced to a sealed internal vacuum cavity, rather than to ambient atmosphere. Absolute sensors sit one tier below gauge and differential pressure sensors in the transducer hierarchy (absolute -> gauge -> differential) and one tier above raw piezoresistive silicon strain gauges. The MPXH6300A6U sits at the top of the NXP/ST MPXHxxxx family for high-pressure (up to ~3 atm) industrial and automotive applications such as manifold absolute pressure (MAP) sensing and barometric correction. Key differentiating features include on-chip bipolar op-amp signal conditioning, thin-film laser-trimmed resistor networks for temperature compensation, and a high-temperature operating range of -40 C to +125 C. The integrated ASIC eliminates the need for external amplification or calibration circuitry, allowing direct connection to an ADC input or microcontroller. The 5.0 V nominal supply, 0.3-4.9 V output swing, and ratiometric architecture simplify MCU firmware scaling, since Vout/Vin tracks the pressure ratio directly. Technically, the device uses a piezoresistive transducer element whose Wheatstone bridge resistance changes with applied pressure, followed by a precision chopper-stabilized instrumentation amplifier. The sensor is calibrated across 0 to 85 C with second-order temperature correction, achieving a typical accuracy of better than +/-1.5% VFSS. Power consumption is approximately 10 mA from a 5 V supply, and the SSOP-8 package provides a stable platform for surface-mount assembly. Typical applications include automotive MAP sensors, barometric altimeters, industrial process control, HVAC pressure monitoring, and weather station instrumentation. It is well-suited where a calibrated, ratiometric analog output is preferred over a digital I2C/SPI interface. Design considerations include using a stable 5.0 V supply to preserve ratiometric accuracy, providing adequate PCB isolation from vibration, and adding ESD protection at the sensor port for harsh environments. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes for the MPXH6300A6U that go beyond the manufacturer datasheet to help engineers select, source, and implement this absolute pressure sensor.
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.

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.

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.

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.
