MPX12GP - 10 kPa Uncompensated Pressure Sensor 4-SIP | NXP
The NXP MPX12GP is a 10 kPa uncompensated silicon piezoresistive pressure sensor in a 4-SIP through-hole module with a male 0.19" (4.93 mm) pressure port, specified for vented-gauge measurements and typically sold by STMicroelectronics and NXP/Freescale in the same datasheet family. It delivers a differential analog output of 0 mV to 55 mV at a 3 V supply, providing a linear, low-cost transducer element that designers can pair with their own external temperature-compensation and signal-conditioning networks. The sensor targets 1.45 PSI (10 kPa) full-scale pressure and is part of the legacy MPX10/MPX12 uncompensated family that Motorola introduced and Freescale/NXP later transferred into their own product lines. According to the manufacturer datasheet (MPSD-001), the device is built using a monolithic silicon piezoresistive die and a ported 4-SIP case that simplifies PCB mounting and pneumatic hose attachment. A piezoresistive pressure sensor is a transducer that converts applied mechanical pressure into a proportional change of resistance in four silicon strain gauges arranged in a Wheatstone bridge. The bridge is excited by a constant voltage or current, and the resulting differential output voltage scales linearly with applied pressure. Uncompensated sensors like the MPX12GP expose the raw bridge output, allowing designers to add precision op-amps, temperature-compensation lookup tables, and digital calibration - a trade-off favored in cost-sensitive medical and HVAC designs where full signal-chain integration is acceptable. The hierarchy is: pressure sensor -> transducer -> sensor -> electronic component. The MPX12GP sits at the uncompensated, low-cost end of this hierarchy, with compensated and amplified siblings (e.g. MPX4115A, MPX5700) providing higher-level outputs at higher cost. Key specifications include a 10 kPa (1.45 PSI) full-scale pressure range, 0 mV to 55 mV output span at 3 V excitation, ±0.5% linearity, and an operating temperature range of -40 °C to +125 °C. The 4-SIP package style (Case 344B-01) provides a single axial pressure port and four through-hole pins that align 1:1 with the MPX10GP, MPX12DP, and MPX12GP variants. Because the device is uncompensated, designers must characterize the offset, span, and temperature coefficient of the bridge externally. Typical applications include medical spirometry, respiratory monitoring, HVAC duct pressure sensing, altimeters, and low-pressure process instrumentation. The wide operating temperature and simple port geometry also support industrial pneumatic sensing where calibrated offset correction is acceptable. A key design consideration is that uncompensated output requires a low-drift instrumentation amplifier (such as an AD620 or INA128) and a temperature-compensation network. A 1 mA constant-current excitation source will minimize span drift versus temperature compared to a fixed-voltage supply, and a 5th-order polynomial or a 2D lookup table in the host MCU will remove residual non-linearity. This page synthesizes distributor pricing, pin-compatible drop-in alternatives, and practical signal-conditioning notes that go beyond what is published in the bare manufacturer datasheet - making it directly useful to design engineers evaluating pressure-sensing architectures.
MPX2010D - 10kPa Differential Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX2010D is a silicon piezoresistive differential pressure sensor with a 10 kPa (1.45 PSI) full-scale range, housed in a 4-SIP through-hole module (Case 344-15). It delivers a linear analog output from 0 mV to 25 mV at a 10V excitation supply, with on-chip laser-trimmed span and offset calibration plus integrated temperature compensation over 0C to +85C. A piezoresistive pressure sensor is a transducer that converts applied gas or liquid differential pressure into a proportional electrical signal by exploiting the piezoresistive effect in doped silicon. Within the broader hierarchy, the MPX2010D is classified as a MEMS pressure sensor, then as a pressure transducer, then as a signal-conditioning sensor, and ultimately as an integrated semiconductor component. Compared to ceramic capacitive or strain-gauge bridge sensors, piezoresistive silicon sensors offer higher sensitivity in a smaller die, but require a stable excitation voltage and are typically limited to lower pressure ranges. Key features include a 10 kPa full-scale pressure range with differential (Port 1 vs Port 2) measurement topology, 2.5 mV/kPa nominal sensitivity, 0.1% linearity over the compensated range, and an operating temperature range of 0C to +85C. The monolithic silicon diaphragm integrates the strain gauge and thin-film resistor network on-chip, while the uncompensated family cousin MPX2010GP (Case 344B-01) shares the same die but ships un-calibrated for cost-sensitive designs. The MPX2010D uses a four-arm Wheatstone piezoresistive bridge diffused into a single silicon diaphragm. When pressure is applied across Ports 1 and 2, the diaphragm flexes and unbalances the bridge proportionally to the differential pressure. Laser trimming of on-chip resistors calibrates span and offset, and on-chip thin-film resistors implement first-order temperature compensation, removing the need for external compensation networks in most designs. Typical applications include medical respiratory monitoring (spirometers, ventilators), HVAC airflow and differential pressure measurement, industrial process control, altimeters and barometric instrumentation, and portable blood-pressure cuffs. Designers select this part when a calibrated, temperature-compensated, low-pressure differential measurement is required without external signal conditioning. When designing with the MPX2010D, provide a stable low-noise 10V excitation supply and a low-offset instrumentation amplifier such as the INA128 or AD620 to scale the 25 mV full-scale output to a usable 0-5V or 4-20 mA signal. Use anti-aliasing filtering between the sensor output and ADC, and isolate mechanical stress on the SIP package leads from the sensing ports to prevent PCB-induced offset drift.

MPX2010DP - 10 kPa Differential Pressure Sensor | NXP/STMicro
The NXP MPX2010DP is a 10 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor delivering a linear voltage output directly proportional to applied differential pressure. Housed in a 4-SIP module with dual 0.19 inch (4.93 mm) tube ports, it provides a full-scale span of 25 mV at 10 V excitation and is intended for non-corrosive gas or dry air media. A piezoresistive pressure sensor is a solid-state transducer whose Wheatstone-bridge strain gauges diffused into a silicon diaphragm convert mechanical strain into a proportional millivolt-level voltage output. Within the broader transducer taxonomy, this device sits at: piezoresistive sensor -> MEMS pressure sensor -> pressure transducer -> sensor. The on-chip thin-film resistor network delivers a temperature-compensated, calibrated output that simplifies the signal-chain by removing the need for external compensation circuitry in many designs. Key features include 0 to 10 kPa (0 to 1.45 PSI) differential pressure range, 25 mV typical full-scale span at 10 V supply, ±0.05% linearity, ±0.1% to ±2.5% temperature compensation across 0 to 85 °C, and a fast 1.0 ms response time. The 4-SIP through-hole package aligns the dual pressure ports along the sensor axis and supports pressures applied via flexible tubing up to 75 kPa maximum overpressure and 200 kPa burst pressure. According to the NXP product overview, the device operates from -40 °C to +125 °C, making it suitable for industrial and consumer environments. Typical applications include HVAC air-flow monitoring, medical respirators and ventilators, barometric altimeters, industrial process control loops, level detection in sealed containers, and water-column altitude measurement. The dual-port differential topology allows reference-pressure measurement, eliminating barometric drift in measurements where gauge pressure is converted to absolute flow. When designing with the MPX2010DP, place the device in a region of stable ambient temperature and isolate the ports from condensation; use a differential amplifier (e.g., INA125 or equivalent instrumentation amp) to bring the 25 mV span up to ADC-friendly levels. Bridging the result with a low-offset, low-noise op-amp preserves the calibrated linearity across the full temperature range. The MPX2010, MPXV2010G and MPXM2010 series provide accurate and linear output proportional to applied pressure, ideal for OEM system designs.

MPX2010GP - 10 kPa Vented Gauge Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX2010GP is a 10 kPa (1.45 PSI) silicon piezoresistive pressure sensor in a 4-lead SIP module (Case 344B-01) with a vented gauge male port. It delivers a linear voltage output of 0 mV to 25 mV at 10 V excitation, directly proportional to applied pressure, with on-chip temperature compensation and calibration. A pressure sensor is a transducer that converts an applied gas or fluid pressure into a proportional electrical signal. Pressure sensors fit into the sensor hierarchy as follows: pressure sensor -> force/pressure transducer -> MEMS sensor -> semiconductor device. Within this hierarchy, piezoresistive sensors use a strained silicon diaphragm whose resistance changes with mechanical deformation; signal-conditioning circuitry converts this Wheatstone-bridge change into a millivolt-level voltage output that downstream amplifiers can scale to 0-5 V or 4-20 mA. The MPX2010GP uses a single monolithic silicon diaphragm with an integrated strain gauge and thin-film resistor network. On-chip temperature compensation holds sensitivity within tight limits across the operating range, removing the need for external thermistor networks. The device operates over a -40 C to +125 C range and is specified for 0 to 10 kPa differential or gauge pressure, making it suitable for low-pressure medical, HVAC, and instrumentation uses. The vented gauge port references the back side to ambient pressure, eliminating vacuum-pump calibration. Typical applications include medical respiration monitors, HVAC variable-air-volume (VAV) controllers, industrial process instrumentation, altimeters, and low-pressure laboratory measurement. The 25 mV full-scale output requires a low-noise instrumentation amplifier (INA, AD620-class) to drive an ADC. The MPX2010GP series remains a workhorse for low-pressure designs and is widely second-sourced. When designing with this device, route the high-impedance mV signal on a guarded, short trace and add RC low-pass filtering at the amplifier input to suppress RF rectification. Avoid mechanical stress on the plastic port during PCB assembly - the silicone gel isolation only protects the die from chemical and thermal attack, not from mounting force.

MPX2010GS - 10 kPa Gauge Pressure Sensor | NXP | SIP-4
The NXP MPX2010GS is a 10 kPa (1.45 psi) on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor packaged in a 4-SIP module with a 0.19" (4.93 mm) male tube vented-gauge port. It delivers a Wheatstone-bridge analog output spanning 0 mV to 25 mV at 10 V excitation and operates from a 10 V to 16 V supply. The series translates applied pressure into a highly linear, calibrated voltage for direct interface with instrumentation amplifiers and microcontrollers with on-board ADCs. A piezoresistive pressure sensor is a transducer whose conversion of mechanical pressure into an electrical signal relies on a silicon diaphragm embedded with diffused Wheatstone-bridge resistors; when pressure deflects the diaphragm, the bridge imbalance produces a differential output proportional to the applied pressure. The MPX2010GS belongs to the board-mount pressure-sensor family within the broader transducer (sensor -> pressure sensor -> piezoresistive sensor -> gauge pressure sensor -> silicon pressure sensor) taxonomy and is commonly used wherever a small, linear, temperature-stabilized pressure-to-voltage conversion is required. Key differentiating specifications include an operating pressure range of 0 to 10 kPa (0 to 1.45 psi), an output of 0 mV to 25 mV at 10 V, a Wheatstone-bridge analog output type, vented-gauge pressure type referenced to atmosphere, on-chip temperature compensation and calibration, and a 10 V to 16 V supply range. The integrated signal conditioning, calibration, and temperature compensation eliminate external compensation networks and reduce BOM count. At its core, the MPX2010GS uses a single-element piezoresistive die laser-trimmed for span and offset, with on-chip compensation networks (resistors) flat across the 0 to 85 C operating range. The hermetic SIP-4 housing isolates the die from ambient humidity and provides a barbed tube port for pneumatic connection, with a vent port to atmosphere providing gauge (vs. absolute or differential) reference. Compared with uncompensated bare-die sensors, the integrated compensation substantially reduces system-level drift error. Typical applications include medical respirators and ventilators, HVAC variable-air-volume (VAV) controllers, industrial process controllers, barometric/altimeter instrumentation, level measurement, and consumer appliances such as washing-machine water-level sensors. The 10 kPa range suits low-pressure medical and HVAC use cases where barometric noise would otherwise swamp a higher-range transducer. When designing with the MPX2010GS, place an instrumentation amplifier (e.g., INA125, AD620, or NXP MPXAZ5010 interface) directly at the Wheatstone output to convert the millivolt bridge signal to a usable 0-5 V or 4-20 mA signal. Use a stable, low-noise excitation source (10 V typical) because sensor span scales linearly with excitation; noise and drift on the supply will be reflected in the output. Apply a bypass capacitor near the supply pin.

MPX2010GSX - 10kPa Pressure Sensor, 4-SIP, STMicroelectronics
The STMicroelectronics MPX2010GSX is a silicon piezoresistive pressure sensor providing a linear voltage output of 0 mV to 25 mV at 10 kPa (1.45 PSI) full-scale span, housed in a 4-SIP through-hole module with a 0.19" (4.92 mm) tube port for vented gauge measurement. The monolithic silicon diaphragm integrates strain-gauge and thin-film resistor networks on-chip, laser-trimmed for precise span, offset calibration and temperature compensation across 0°C to +85°C. Pressure sensors like the MPX2010GSX are transducers that convert an applied pressure into a proportional electrical signal. Within the broader sensor hierarchy they belong to MEMS (Micro-Electro-Mechanical Systems) devices, and more specifically to piezoresistive pressure sensors - a category that uses strain-induced resistance changes in silicon to produce a Wheatstone-bridge output voltage. Unlike capacitive or optical pressure sensors, piezoresistive designs offer simple excitation (10 V typical), high linearity, and ratiometric output ideal for low-pressure medical and instrumentation applications. Key features include 25 mV full-scale span at 10 V excitation, 0.45% linearity typical, 1.0 mV/kPa sensitivity, on-chip temperature compensation from 0°C to +85°C, and ratiometric output proportional to supply voltage. The 4-SIP package with axial tube port simplifies pneumatic interface, while the through-hole mounting provides robust mechanical retention on the PCB. The MPX2010GSX uses a single monolithic silicon diaphragm with an integrated four-resistor Wheatstone strain-gauge bridge. Laser-trimmed resistors calibrate span and offset at room temperature, with additional thin-film compensation networks maintaining accuracy across the 0°C to +85°C operating range. Excitation at 10 V DC produces a ratiometric output that scales linearly with supply, simplifying ADC interface design. Typical applications include medical respiratory monitoring (spirometers, ventilators), HVAC airflow sensing, industrial process control, and altimeter/barometric reference designs where the 0-10 kPa gauge range matches inhalation flow or low-differential process pressures. When designing with this device, ensure a stable low-noise 10 V excitation supply; supply ripple directly couples into the output. The 0.19" tube port must be sealed against contamination and moisture, and the through-hole pins require strain relief if the pneumatic line applies mechanical load. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers shorten the selection and qualification cycle for 10 kPa vented-gauge pressure sensing.
MPX2050D - 50 kPa Differential Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX2050D is a 50 kPa (7.25 PSI) differential piezoresistive silicon pressure sensor in a 4-lead SIP (Single In-line Package) module, providing a highly accurate and linear voltage output directly proportional to the applied pressure. The device integrates a monolithic silicon diaphragm, on-chip strain gauge, thin-film resistor network, and laser-trimmed span/offset calibration, with 0 mV to 40 mV output swing across the full pressure range when excited with 10 V DC. The differential configuration measures the pressure difference between two inlet ports, suitable for applications where gauge-like measurements are needed without atmospheric reference. A piezoresistive pressure sensor is a MEMS (Micro-Electro-Mechanical Systems) device that exploits the piezoresistive effect in silicon—where applied mechanical stress alters the electrical resistance of implanted resistors—to convert pressure into a measurable voltage. The MPX2050D is part of the broader transducer family hierarchy: pressure sensor → pressure transducer → sensor → electronic component. Its on-chip temperature compensation eliminates the need for external correction networks, simplifying analog signal chain design. Key features include a 0–50 kPa operating range, 0.5% typical linearity, 0.45 mV/kPa typical sensitivity at 10 V excitation, ±0.05% to ±0.2% accuracy across 0–85°C, and a 5 kHz response time. The temperature-compensated output spans −40°C to +125°C, with the laser-trimmed resistors calibrating both span and offset during manufacture. The 4-SIP package provides port access on the inlet side for differential measurement. The sensor uses a Wheatstone-bridge arrangement of piezoresistors diffused into the silicon diaphragm; deflection under pressure unbalances the bridge, producing a differential output voltage. Laser trimming during wafer-level test sets span and offset, while integrated thin-film resistors implement first-order temperature compensation of both span and offset across the operating range. Typical applications include HVAC differential pressure monitoring, medical respiratory equipment, industrial process control, altimeters and variometers, and level measurement in sealed tanks. Designers favor the MPX2050D for its calibrated, linear mV output that interfaces directly with instrumentation amplifiers. When designing with this part, use a low-noise instrumentation amplifier such as the INA125 or INA128 to amplify the 40 mV full-scale output to a usable ADC range. Apply a regulated 10 V excitation to maintain calibration accuracy. Note that the differential port configuration means the sensor measures ΔP between two inlets—do not use it for absolute pressure measurements.
MPX2050GP - 50 kPa Vented Gauge Pressure Sensor | NXP / STMicro
The NXP (formerly Motorola/Freescale, now also STMicro) MPX2050GP is a 50 kPa (7.25 PSI) on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor in a 4-SIP through-hole module with a male 0.19" (4.93 mm) tube port. It delivers a highly linear 0 mV to 40 mV differential analog output at 10 V excitation, making it a classic transducer for medical and HVAC instrumentation. The single monolithic silicon diaphragm integrates a strain gauge and a thin-film resistor network, laser-trimmed for precise span, offset calibration, and temperature compensation across 0C to 85C. A pressure sensor (or pressure transducer) is a device that converts an applied pressure into a measurable electrical signal. Piezoresistive sensors achieve this by exploiting the change in silicon resistance when mechanical strain is applied to an integrated diaphragm. Within the broader sensor hierarchy, the MPX2050GP sits under MEMS sensors -> pressure sensors -> piezoresistive transducers -> board-mount sensor modules. This category is essential whenever a system must monitor fluid or gas pressure for safety, control, or measurement purposes, and analog-output parts like the MPX2050GP remain preferred when interfacing with legacy analog front-ends, instrumentation amplifiers, or microcontroller ADCs. Key features of the MPX2050GP include 0 to 50 kPa (0 to 7.25 PSI) gauge measurement, vented gauge reference for absolute-vs-differential applications, 0 to 40 mV full-scale span (typ) at 10 V supply, low offset drift over 0 to 85C, and a 4-pin unibody SIP package that mounts directly onto a PCB or in-line tubing manifold. The vented gauge configuration allows the back side of the diaphragm to sense atmospheric pressure through the port, simplifying medical and barometric-style designs. The device uses a piezoresistive Wheatstone bridge on the silicon die; laser trimming during manufacture calibrates both offset and span, eliminating most external compensation components. Typical full-scale output is 40 mV at 10 V excitation (4 mV/V), linearity is ~0.05% to 0.1% of full scale, and pressure hysteresis is below 0.1% across the operating range. Typical applications include medical respiratory monitors, HVAC air-flow and filter monitoring, industrial process control, barometric reference sensing, and altimeter/barometer modules. The 4 mV/V sensitivity makes it well-suited to direct ADC input after a low-noise instrumentation amplifier. When designing with this part, pay attention to input excitation noise: a clean, low-noise 10 V reference (or regulated supply) is required because any ripple couples directly into the output. Mount the SIP module mechanically to avoid stress on the pressure port and use a sealed manifold for liquids.

MPX2053D - 50kPa Differential Pressure Sensor 4-SIP | STMicroelectronics
The STMicroelectronics MPX2053D is a 50 kPa on-chip temperature compensated and calibrated silicon piezoresistive differential pressure sensor that delivers a linear voltage output directly proportional to applied pressure.

A piezoresistive pressure sensor is a MEMS device that converts mechanical pressure into an electrical signal by exploiting the piezoresistive effect in silicon, where strain-induced changes in the silicon crystal lattice alter resistivity. The single monolithic silicon diaphragm integrates the strain gauge and thin-film resistor network on-chip. This architecture falls within the broader hierarchy of: pressure sensor -> transducer -> sensor -> electronic component. Temperature compensation and laser-trimmed span/offset calibration eliminate the need for external signal conditioning in many low-precision applications. Key features include on-chip temperature compensation across 0 to 85 C, laser-trimmed offset and span calibration, a differential pressure configuration that rejects common-mode pressure, ratiometric analog output proportional to supply voltage, and a robust unibody plastic package rated for harsh-environment media when fitted with a port adapter. The chip is laser trimmed for precise span and offset calibration and temperature compensation. Typical applications include HVAC airflow monitoring, medical respiratory instrumentation, industrial process control, altimeters and barometers, and pneumatic system monitoring. The differential configuration is particularly useful where both sides of the diaphragm are exposed to measured media rather than atmosphere. When designing with this device, designers must provide a stable 10 V DC excitation supply (typical) and an instrumentation amplifier with high common-mode rejection ratio to extract the low-milliVolt signal cleanly. Port orientation and tubing must be selected to avoid condensation or media contamination of the sensing die.

The MPX2053DP features a typical full-scale span of 40 mV at 10 V supply, a maximum offset of ±1.0 mV, and a response time of 1.0 ms. The device operates from a single 10 V typical supply (maximum 16 V) and is specified over 0 °C to +85 °C. Ratiometric output means the span scales linearly with supply voltage, simplifying ADC interfacing.

Typical applications include medical instrumentation (respiratory monitors, ventilators, blood pressure monitors), HVAC airflow and filter monitoring, industrial process control, level detection, and barometric differential measurement. The 0.8 mV/kPa sensitivity makes the device well-suited for low-pressure biomedical and environmental sensing. Designers should use a high-precision instrumentation amplifier (such as an INA126 or AD620) to boost the 40 mV full-scale output to a usable 0-5 V or 4-20 mA range. Add 100 nF supply decoupling close to the sensor pins and a resistive bridge-drive configuration if ratiometric ADC sampling is required.

Typical applications include HVAC pressure monitoring, medical respiratory equipment, process control, altimeters and barometers, and industrial pneumatic systems. Its low cost and calibrated output make it well suited for high-volume consumer and industrial designs requiring reliable gauge pressure measurement. When designing with this device, ensure a clean, regulated 10 V supply for specified performance, and account for the millivolt-level output signal by using low-noise instrumentation amplifiers (such as INA128 or AD620) to boost the signal before ADC conversion. Proper port plumbing and protection from moisture ingress will extend operational life.

The NXP MPX2053GVP is a 50 kPa on-chip temperature-compensated and calibrated silicon piezoresistive pressure sensor in a 4-SIP top-port module with a male 4.93 mm tube inlet, delivering a linear 0 mV to 40 mV output at 10 V excitation for gauge pressure from 0 to 7.25 PSI (50 kPa). It is part of the legacy MPX2053 family originally introduced by Motorola and now maintained by NXP, designed for direct interface with microcontrollers and A/D converters without external signal conditioning. A piezoresistive pressure sensor is a MEMS device in which a silicon diaphragm with embedded Wheatstone bridge resistors deflects under applied pressure, converting mechanical force into a differential millivolt output proportional to pressure. Pressure sensors sit within the broader transducer hierarchy as part of the sensor signal chain, downstream of physical phenomena and upstream of analog front-end (AFE) or ADC stages in measurement and control systems. Key features include on-chip temperature compensation over the -40 C to +125 C range, calibrated span and offset for drop-in use, a 0 mV to 40 mV full-scale output at 10 V supply, and a vented gauge reference that measures pressure relative to ambient through the rear of the package. The Wheatstone bridge topology provides good linearity and low noise when excited from a stable low-impedance source. Typical applications include HVAC blower and duct pressure monitoring, medical respiratory and ventilator equipment, industrial process control, altitude and barometric sensing, and appliance water-level detection. The vented gauge port design eliminates the need for external barometric correction in differential applications. When designing with this device, decouple the supply with a 100 nF ceramic capacitor close to the supply pin and drive the bridge from a low-noise, low-impedance reference to minimize self-heating and span drift. Use a high-resolution ADC with at least 12 bits to resolve the 40 mV full-scale span.

MPX2100A - 100kPa Absolute Pressure Sensor, 40mV | NXP Semiconductors
The NXP Semiconductors (formerly Motorola/Freescale) MPX2100A is a 100 kPa (14.5 psi) absolute pressure sensor in a 4-SIP through-hole module, delivering a linear analog voltage output proportional to applied pressure. It produces a 0 mV to 40 mV full-scale span (typical) at a 10 V supply, with on-chip temperature compensation and calibration across 0°C to 85°C. The device uses a silicon piezoresistive sensing element with a differential amplifier stage on the same die. A piezoresistive pressure sensor is a MEMS device in which four piezoresistors arranged in a Wheatstone bridge on a silicon diaphragm change resistance when the diaphragm flexes under pressure. The MPX2100A belongs to the pressure transducer product family, under MEMS sensors, which in turn sits within the broader sensor hierarchy: pressure sensors -> sensors -> signal conditioning -> data acquisition systems. Absolute-pressure variants (suffix "A") measure pressure referenced to a sealed vacuum cavity on the die, distinct from gauge ("G") or differential ("D") variants. Key features include 40 mV full-scale span (typical), 0 mV to 40 mV output range, 10 V typical supply, ±0.25% linearity (best-fit straight line), ±1.0% temperature hysteresis, and 1.0% full-scale span temperature error. The device provides a sensitivity of approximately 0.4 mV/kPa at 10 V excitation, with an operating temperature range of -40°C to +125°C. Internal calibration eliminates the need for external compensation networks in most applications. The MPX2100A architecture combines a diffused piezoresistive bridge with a thin-film gain network and a laser-trimmed offset adjustment, providing ratiometric output directly proportional to supply voltage. This ratiometric behavior simplifies analog-to-digital conversion when the excitation source also serves as the ADC reference. The unibody 4-SIP package provides port-style pressure access through a single tube inlet. Typical applications include medical instrumentation (blood pressure monitors, respiratory equipment), HVAC pressure measurement, altimeters and barometric systems, industrial process control, and pneumatic controls. The absolute-pressure reference makes the device particularly suitable for sealed-system measurements where atmospheric variation must be excluded. When designing with the MPX2100A, an instrumentation amplifier such as the MCP6N11 or AD8421 is typically required to boost the 40 mV full-scale output to a usable 0-5 V or 4-20 mA range. Use a low-noise, low-drift precision op-amp and provide a clean, regulated 10 V excitation to maintain specified linearity.

MPX2100AP - 100kPa Absolute Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX2100AP is a silicon piezoresistive absolute pressure sensor rated for 0 to 100 kPa (0 to 14.5 psi), housed in a 4-SIP module with an axial male 0.19 inch (4.93 mm) tube port. It delivers a typical full-scale span of 40 mV at 10 V excitation, providing a linear voltage output that is directly proportional to applied pressure. According to the manufacturer datasheet, the sensor integrates a monolithic silicon diaphragm, an on-chip strain gauge, and a thin-film resistor network that is laser-trimmed for span, offset, and on-chip temperature compensation. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a transducer that uses the piezoresistive effect in silicon - where mechanical strain changes carrier mobility - to convert applied pressure into a measurable voltage. Piezoresistive sensors sit in the broader transducer family alongside capacitive, piezoelectric, and resonant sensors, and they are widely used where DC response, low cost, and PCB-mountable packaging are required. The MPX2100AP specifically targets absolute (sealed vacuum reference) pressure measurement rather than differential or gauge measurement. Key features of the MPX2100AP include 0 to 40 mV output span, ±0.25% linearity per the manufacturer datasheet, ±0.5% temperature compensation over 0°C to 85°C, and an operating temperature range of -40°C to +125°C. The uncompensated nature of the output keeps the part economical but requires external signal conditioning - typically an instrumentation amplifier such as the INA125, INA128, or MAX4475 - to amplify the small millivolt signal to a usable 0-5 V or 4-20 mA range. The 4-SIP module provides a robust port for pneumatic or hydraulic coupling in industrial environments. The MPX2100AP uses a Wheatstone-bridge configuration on a single silicon die, which simplifies the external interface to four pins: power, ground, and two differential outputs. This architecture inherently rejects common-mode noise and supports ratiometric measurements when paired with a stable excitation supply. Designers should select a low-drift, low-noise excitation reference to fully exploit the on-chip temperature compensation. Typical applications include medical respirators and ventilators, HVAC pressure monitoring, process control instrumentation, altimeters and barometers, leak detection, and pneumatic system monitoring. The absolute-pressure reference makes it particularly suitable for barometric and sealed-system use, where the device reads absolute rather than differential pressure. A key design consideration is that the 40 mV full-scale output is very small, so PCB trace routing should minimize stray capacitance and thermal EMF; route the differential outputs as a balanced pair to the instrumentation amplifier with proper guarding. For ratiometric measurements, derive the ADC reference from the same 10 V excitation supply to cancel supply-noise errors.

MPX2100ASX - 100 kPa Absolute Pressure Sensor | NXP Semiconductors
The NXP Semiconductors MPX2100ASX is a 100 kPa on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor that delivers a highly linear voltage output directly proportional to applied absolute pressure, housed in a 4-SIP through-hole module with axial tube pressure port (0.19 inch / 4.92 mm). The device produces a 0 mV to 40 mV full-scale output at 10 V excitation, operating over a 14.5 PSI (100 kPa) absolute pressure range. An absolute pressure sensor is a transducer that measures pressure referenced to a sealed vacuum reference chamber rather than ambient atmosphere; this allows accurate altitude-independent pressure readings across wide environmental conditions. The MPX2100 series belongs to the piezoresistive silicon sensor family, sitting within the broader sensor taxonomy: pressure sensor -> board mount pressure sensor -> MEMS sensor -> semiconductor device. Absolute variants are essential in applications where atmospheric pressure varies (e.g., unmanned aerial vehicles, weather instrumentation) because the sealed vacuum reference provides a stable zero point. Key features include on-chip signal conditioning via a monolithic piezoresistive Wheatstone bridge, factory calibration at 10 V excitation, and laser-trimmed resistors for temperature compensation across the operating range. The 4-SIP module package is designed for through-hole PCB mounting with an integrated axial pressure port that accepts a 4.92 mm tube, simplifying pneumatic interfacing in industrial equipment and medical instruments. The MPX2100ASX architecture uses a single silicon diaphragm with diffused piezoresistive strain gauges arranged in a Wheatstone bridge; this monolithic approach reduces part count, eliminates external calibration, and provides robust ratiometric output that scales linearly with excitation voltage. The vacuum reference is hermetically sealed on the rear of the die, ensuring long-term reference stability. Typical applications include barometric pressure measurement in weather stations, altimeters for drones and aviation instrumentation, industrial process control, HVAC pressure monitoring, and medical respiratory equipment such as spirometers and ventilators. The wide operating pressure range and sealed absolute reference also suit vacuum system monitoring and sealed gas pressure applications. When designing with this part, place the 4-SIP module with adequate clearance around the axial tube inlet to ensure reliable pneumatic connection. Use a stable low-noise excitation supply of 10 V DC; ratiometric output means supply noise translates directly into measurement noise, so the supply should be well decoupled. This page synthesizes distributor pricing snapshots, drop-in pin-compatible alternatives, and practical design notes that are not collected together on any single manufacturer datasheet, enabling faster integration of the MPX2100ASX into new pressure measurement designs.

The device is on-chip temperature compensated and factory calibrated for simplified design-in. A piezoresistive pressure sensor is a MEMS device in which a diaphragm with implanted strain gauges converts pressure-induced mechanical strain into a proportional change in resistance; that change is read out as an electrical signal. Inside the broader sensor hierarchy, the MPX2100D belongs to the family of pressure sensors, then to transducers, then to sensors in general, then to signal conditioning and data acquisition subsystems. Differential variants measure the difference between two pressure ports rather than absolute pressure referenced to a sealed vacuum, making them ideal for flow measurement and gauge-pressure applications where the reference side is vented to atmosphere. Key features include a 0.4 mV/kPa nominal sensitivity, a maximum supply voltage of 16 V with a recommended 10 V excitation, and a wide operating temperature range suitable for industrial and medical environments. The unibody SIP package integrates port geometry and provides a rugged mechanical interface. Typical full-scale output is 40 mV at 10 V for 100 kPa applied pressure. The MPX2100D uses a single-chip silicon strain-gauge bridge with on-die laser-trimmed compensation resistors, eliminating the need for external temperature or offset correction networks in most applications. The Wheatstone bridge configuration delivers a ratiometric output that scales with supply voltage, allowing the user to trade noise and power for dynamic range by varying excitation. Typical applications include medical respiration and ventilation monitors, HVAC blower and filter pressure sensing, industrial process control, altimeters and barometric instruments, and pneumatic control systems. Across these uses, differential sensing is preferred when one side must be referenced to a known low-pressure environment. When designing with this part, provide low-noise, well-regulated excitation and condition the millivolt-level output with an instrumentation amplifier such as the INA128 or AD620 before ADC conversion. Route pressure tubes with care to avoid water hammer or particulate contamination of the port.

It is housed in a 4-SIP module package (Case 344C-01) with dual 4.93 mm (0.19 inch) tube ports for differential measurements and operates on a single 10 V supply. The monolithic silicon diaphragm integrates a strain gauge and thin-film resistor network on-chip, providing temperature compensation and a linear mV output without requiring external signal conditioning for many applications. A piezoresistive pressure sensor is a transducer that converts applied pressure into a change in electrical resistance via strain gauges diffused into a silicon diaphragm. As pressure deforms the diaphragm, the embedded Wheatstone bridge produces a differential voltage proportional to the pressure differential between the two ports. The MPX2100DP sits within the broader sensor hierarchy: pressure sensor -> MEMS transducer -> board-mount sensor -> electronic component. The 4-SIP package with axial tubes makes it suitable for through-hole mounting on PCBs and inline pneumatic systems, distinguishing it from surface-mount MEMS alternatives. Key features include a 0-100 kPa measurement range, 40 mV full-scale span, 1.0% typical linearity, and on-chip temperature compensation over 0-85°C. The differential dual-port configuration allows measurement across a filter, orifice, or any element where two pressure taps are available. According to the manufacturer datasheet, the device provides a calibrated output with minimal offset drift and is laser-trimmed for span accuracy, simplifying interface to ADC front ends and instrumentation amplifiers. Typical applications include medical instrumentation (respiratory monitors, blood pressure measurement, inhalers), industrial process control (HVAC pressure monitoring, filter clog detection, vacuum systems), and consumer devices (altimeters, barometers, appliance pressure sensing). The wide operating pressure range and differential measurement capability make it especially suitable for low-pressure pneumatic and biomedical applications where bidirectional or differential readings are required. When designing with the MPX2100DP, select a low-noise, low-drift instrumentation amplifier (such as an INA12x series or similar) for the mV-level output, and ensure stable 10 V excitation for rated performance. Decouple the sensor supply near the device pins with a 0.1 uF ceramic capacitor to suppress supply noise. The tube ports should use flexible silicone tubing with appropriate clamps to avoid mechanical stress on the package.

MPX2100GP - 100kPa Vented Gauge Pressure Sensor | NXP
The NXP MPX2100GP is a silicon piezoresistive pressure sensor providing a highly accurate and linear voltage output directly proportional to the applied pressure, in a 4-SIP through-hole module with a 0.19" (4.93 mm) barbed tube port. It measures a 0 to 100 kPa (0 to 14.5 psi) vented gauge pressure range and delivers a full-scale span of 40 mV typical at 10 V supply, with on-chip temperature compensation and calibration already applied. A pressure sensor transducer generates an electronic signal proportional to the applied pressure, typically by exploiting the piezoresistive effect in silicon. The MPX2100GP belongs to the board-mount pressure sensor family, a subset of signal-conditioning sensors that sit between the physical environment and the microcontroller analog front end. In the broader sensor taxonomy it falls under silicon MEMS -> piezoresistive sensor -> board mount pressure sensor -> signal chain component. Key features include a maximum operating current of 6 mA, a Wheatstone bridge output topology, 58.02 psi (400 kPa) maximum overpressure rating, and an operating temperature range suited for industrial environments. The on-chip temperature compensation eliminates the need for external compensation networks, simplifying the analog front end. The 4-SIP module with port-style barbed tube integrates the sensing element and the compensation network into a single through-hole package that is easy to mount and seal with flexible tubing. Technically, the device uses a diffused silicon strain gauge Wheatstone bridge laser-trimmed for span and offset, then temperature-compensated across 0 to 85°C. The differential output of 0 mV to 40 mV over 0 to 100 kPa gives ~0.4 mV/kPa sensitivity, which is normally amplified by an instrumentation amplifier such as the NXP MPX2010 family counterpart or a dedicated sensor AFE. Typical applications include HVAC controllers, altimeters and barometric instruments, medical respiration monitors, industrial pneumatic gauges, and weather-station barometric pressure sensing. The 4-SIP barbed port supports flexible tubing routing for sealed pressure taps in pneumatic manifolds. When designing with the MPX2100GP, allow adequate mechanical strain relief on the tube port and provide a stable low-noise 10 V excitation supply. The Wheatstone bridge output is ratiometric to supply voltage, so any supply noise or ripple couples directly into the output. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet alone, giving the engineer a single decision-grade reference for the MPX2100GP.
MPX2100GVP - 100 kPa Vented Gauge Pressure Sensor | NXP Semiconductors
The NXP Semiconductors MPX2100GVP is a 100 kPa (14.5 psi) on-chip temperature compensated and calibrated silicon piezoresistive pressure sensor in a 4-SIP through-hole module with a 0.19 inch (4.93 mm) male pressure port. It delivers a highly accurate, linear analog voltage output of 0 mV to 40 mV at 10 V supply, directly proportional to applied pressure. The sensor uses a vented gauge configuration, meaning it references atmospheric pressure on one side of the diaphragm, making it suitable for applications where relative barometric pressure must be measured. A pressure sensor is a transducer that converts an applied mechanical pressure into a proportional electrical signal. Within the broader sensor hierarchy, piezoresistive silicon pressure sensors belong to the MEMS (Micro-Electro-Mechanical Systems) family, which sits under the wider category of physical sensors and ultimately under signal-conditioning and data-acquisition components. These devices typically rely on a Wheatstone-bridge network diffused into a silicon diaphragm; when pressure deflects the diaphragm, the bridge resistors change value and produce a differential output. On-chip temperature compensation maintains accuracy across commercial and industrial temperature ranges, eliminating the need for external linearization in many designs. The MPX2100GVP integrates the sensing element, signal conditioning, and temperature compensation on a single silicon die. Its full-scale span of 40 mV is calibrated directly by the manufacturer, simplifying the host-side interface to a simple ADC channel or instrumentation amplifier. Operating from a 10 V typical supply (3 V minimum specified for the family, full performance at 10 V), the part draws only 6 mA. The 4-SIP through-hole package with ported tube inlet simplifies hose/fitting integration in industrial equipment, medical instrumentation, and HVAC systems. Maximum operating temperature reaches 125 degrees Celsius, supporting engine-bay and process-control environments. Typical applications include pneumatic control systems, respiratory and medical monitoring equipment, gas-flow instrumentation, altimeters and barometric measurement, and industrial process controllers. The vented-gauge topology means absolute vacuum reads as 0 kPa, and the device rejects common-mode supply noise due to its bridge output structure. When designing with the MPX2100GVP, place a precision instrumentation amplifier (such as an INA125 or AD620) immediately after the sensor output to boost the millivolt-level signal before it reaches the ADC. Add adequate EMI/RFI shielding because the high-impedance bridge output is susceptible to interference. Provide a clean, regulated supply because output is ratiometric to supply voltage.

The NXP Semiconductors MPX2102A is a 100 kPa on-chip temperature compensated silicon piezoresistive pressure sensor that delivers a highly accurate, linear analog voltage output directly proportional to applied pressure, housed in a 4-SIP through-hole module (Case 344-15). It is specified for an absolute pressure range of 20 kPa to 100 kPa and produces a differential output of 0 mV to 40 mV at a 10 V excitation supply. A pressure sensor (also called a pressure transducer) is a device that converts an applied pneumatic or hydraulic pressure into a proportional electrical signal. The MPX2102A belongs to the silicon piezoresistive sensor family, where a single monolithic silicon diaphragm integrates the strain gauge and a thin-film resistor network on-chip; the chip is laser-trimmed for precise span, offset, and temperature compensation across its operating range. Within the broader taxonomy, the part is a MEMS pressure transducer, which sits under sensors > pressure sensors in the electronics hierarchy. Key differentiating features of the MPX2102A include the absolute pressure reference (sealed vacuum on the reference side of the diaphragm), an on-chip thin-film temperature compensation network calibrated at the factory, an operating temperature range from -40C to +125C, and a typical full-scale span of 40 mV at 10 V supply. The 4-SIP module package (Case 344-15) provides a robust through-hole mounting style with barbed pressure port for hose attachment, suitable for industrial and medical use cases. The MPX2102A uses a Wheatstone-bridge configuration formed by the on-chip piezoresistors; when pressure deflects the silicon diaphragm, the bridge unbalances and produces a differential millivolt-level output that is proportional to the pressure differential. Because the output is in the millivolt range, designers should pair the sensor with a low-noise, high-CMRR instrumentation amplifier such as an INA128 or AD620 when high resolution is required. Typical applications include medical instrumentation such as respirators and blood pressure monitors, industrial process control, HVAC barometric measurement, altimeters, vacuum system monitoring, and automotive manifold absolute pressure (MAP) sensing. The on-chip temperature compensation eliminates the need for external RTC or thermistor linearization, simplifying firmware. When integrating the MPX2102A, route the four SIP pins through a low-noise differential ADC front-end and include a 5 kHz low-pass RC filter at the sensor outputs to suppress EMI. The output is ratiometric to the supply, so a stable, low-noise 10 V excitation is critical for achieving the datasheet's 0.25% linearity performance.

It delivers ±0.5% span linearity over the full pressure range with on-chip laser-trimmed temperature compensation across 0 °C to +85 °C. A pressure sensor is a transducer that converts an applied physical pressure into a proportional electrical signal, serving as the analog front-end in fluid, gas, and atmospheric pressure measurement systems. Within the sensor hierarchy the MPX2102AP sits below board-mount pressure sensors and above bare silicon strain gauges; it provides a ratiometric analog output that downstream ADCs or instrumentation amplifiers digitize for system-level reporting. This category is essential in industrial process control, medical instrumentation, HVAC, and consumer appliances where precise pressure data drives safety, regulation, or measurement functions. Key features of the MPX2102AP include 0 mV to 40 mV full-scale span at 10 V excitation, 1.0 ms response time, and robust ±14.5 PSI proof pressure ratings for the absolute configuration. The 4-SIP unibody package provides environmental isolation for the silicon die while exposing a standard barbed tube port for external media connection. Its integrated thin-film resistor network provides span and offset calibration. The MPX2102AP uses a monolithic silicon diaphragm with integrated piezoresistive strain gauges arranged in a Wheatstone bridge configuration. Laser trim during wafer-level calibration removes initial offset and span errors, while on-board compensation resistors correct temperature drift across the operating range. The ratiometric analog output scales with supply voltage, simplifying ADC interfacing and preserving accuracy under varying supply conditions. Typical applications include medical blood pressure monitors, HVAC duct pressure sensing, industrial pneumatic controllers, and barometric altimeters. The temperature-compensated output is suitable for battery-powered portable instruments that operate across wide thermal environments. The 4-SIP barbed port also simplifies integration with silicone tubing for medical and analytical instrumentation. When designing with this part, place a low-offset, low-noise instrumentation amplifier (such as an INA126 or AD620 family) directly at the sensor output to amplify the 40 mV signal to a usable ADC input range. Provide a stable low-noise 10 V excitation (e.g. REF02 or equivalent) to preserve ratiometric accuracy, and isolate the analog and digital grounds with proper star-grounding.
MPX2102ASX - 100kPa Absolute Pressure Sensor | STMicroelectronics
The STMicroelectronics MPX2102ASX is a 100 kPa absolute pressure sensor in a 4-SIP module with a 0.19 inch (4.93 mm) tube side-port, producing a linear analog voltage output of 0 mV to 40 mV at 10 V excitation. It is a silicon piezoresistive device with an on-chip thin-film resistor network laser-trimmed for span, offset, and temperature compensation, delivering a highly accurate, low-drift pressure-to-voltage transfer in a single monolithic diaphragm. A pressure sensor, also known as a pressure transducer, is a device that converts an applied gas or fluid pressure into a proportional electrical signal. Piezoresistive sensors exploit the change in resistance of silicon strain gauges embedded in a flexible diaphragm; as the diaphragm deflects under pressure, the gauges stretch or compress, and a Wheatstone bridge produces a differential output voltage. Pressure sensors belong to the broader class of transducers, which convert one form of energy into another, and they are key building blocks within the Sensors hierarchy (sensor -> transducer -> pressure sensor -> piezoresistive pressure sensor -> absolute pressure sensor) used across industrial, medical, and consumer electronics. Key specifications include an operating pressure range of 0 to 100 kPa (0 to 14.5 PSI absolute), a full-scale span of 40 mV at 10 V supply, an offset of 0 mV to 1.0 mV, and a temperature-compensated range of 0 to 85 degrees Celsius. The device is factory calibrated for span and offset, eliminating the need for external trimming components in most designs. The monolithic die incorporates four piezoresistors arranged as a Wheatstone bridge on a silicon diaphragm; a thin-film laser-trimmed network compensates temperature behaviour across the 0 to 85 degrees Celsius range, simplifying downstream signal conditioning. Typical applications include altimeters and barometric pressure measurement, medical respiratory and blood-pressure instrumentation, HVAC airflow monitors, industrial process control, and environmental weather stations. The 4-SIP module with a ported tube allows easy pneumatic connection via flexible tubing.

MPX2102D - 100kPa Differential Pressure Sensor | NXP | 4-SIP Module
The NXP MPX2102D is a 100 kPa on-chip temperature-compensated silicon piezoresistive pressure sensor housed in a 4-SIP through-hole module. The device delivers a highly accurate, linear Wheatstone Bridge analog voltage output of 0 mV to 40 mV at a 10 V excitation supply, directly proportional to the applied pressure. According to the NXP datasheet, the MPX2102D is rated for a 14.5 PSI (100 kPa) differential pressure operating range and is calibrated directly on the die for high accuracy. A piezoresistive pressure sensor is a MEMS device that converts applied mechanical pressure into a proportional electrical signal using strain-sensitive resistors embedded in a silicon diaphragm. When pressure deforms the diaphragm, the embedded Wheatstone bridge resistors change resistance, producing a differential output voltage. Piezoresistive sensors such as the MPX2102D sit at the bottom of the sensor hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor IC. They are widely used where continuous analog pressure monitoring is required rather than a simple threshold switch. Key features of the MPX2102D include on-chip temperature compensation from 0 C to +85 C, a 0 mV to 40 mV full-scale output, a typical full-scale span of 40 mV at 10 V supply, low offse drift, and a rugged unibody 4-SIP package with dual pressure ports for differential measurement. The integrated signal conditioning and calibration performed at the wafer level eliminate the need for external compensation networks, simplifying downstream amplifier design. The die uses a piezoresistive Wheatstone bridge configured for differential pressure sensing, with a separate reference port exposed on the side of the 4-SIP module opposite the high-pressure port. The on-chip laser-trimmed resistors provide temperature compensation across the rated range, which is essential because raw silicon piezoresistors exhibit strong temperature coefficients that would otherwise degrade measurement accuracy. Typical applications include HVAC airflow monitoring, medical respiration and anesthesia equipment, industrial process control, altimeters and barometric instrumentation, and pneumatic control systems. Its differential measurement capability also makes it well-suited to liquid-level sensing via hydrostatic pressure. When designing with the MPX2102D, ensure that the 10 V excitation supply is well-regulated because output accuracy scales linearly with supply voltage. The Wheatstone bridge output is in the millivolt range and typically requires an instrumentation amplifier such as the INA128 or AD620 before the ADC input. Differential measurements should use both pressure ports and avoid clogging either with particulates.

MPX2102DP - 100kPa Differential Pressure Sensor, 4-SIP | NXP
The NXP MPX2102DP is a 100 kPa on-chip temperature compensated silicon piezoresistive pressure sensor housed in a 4-SIP Dual Port module with 0.19" (4.93 mm) tube ports. A pressure sensor is a transducer that converts an applied pressure into a proportional analog electrical signal; the MPX2102 uses a monolithic silicon diaphragm with an integrated thin-film resistor strain-gauge network, laser-trimmed for high accuracy and linearity, so the differential output between P1 and P2 ports produces a ratiometric voltage directly proportional to applied pressure. Within the broader sensor taxonomy, this part is a piezoresistive MEMS pressure sensor belonging to the micro-electromechanical signal chain, commonly grouped alongside load cells and strain-gauge transducers in industrial and medical instrumentation. Key features include a 0–100 kPa (0–14.5 PSI) differential operating range, 0 mV to 40 mV full-scale output at 10 V excitation, on-chip temperature compensation from 0 °C to +85 °C, and a typical full-scale span of 40 mV that simplifies downstream ADC conditioning. The unibody 4-SIP package integrates the port tube, die, and compensation network, eliminating external temperature-calibration circuitry. The architecture uses a piezoresistive Wheatstone bridge where four diffused resistors change resistance proportionally to membrane stress; the differential bridge output is ratiometric to the supply, so noise-rejection improves when the sensor shares a clean, low-ripple 10 V reference with the ADC. Full-scale span drift is held within ±0.5 % over the compensated temperature range, which is acceptable for medical inhalation and industrial pneumatic control loops. Typical applications include medical spirometers and respirators, HVAC variable-air-volume boxes, process-control pneumatic transmitters, barometric altimeters for portable instrumentation, and industrial pneumatic regulators where differential pressure across an orifice plate must be linearized at the system level. When designing with the MPX2102DP, place a low-offset instrumentation amplifier (e.g., INA125 or AD620) within 100 mm of the sensor pins to avoid injecting PCB leakage drift into the millivolt signal, and decouple the 10 V excitation rail with a 100 nF ceramic capacitor adjacent to Vcc to suppress bridge noise.
