Product details
Overview
MPX10D from NXP Semiconductors is a silicon piezoresistive gauge pressure sensor with 10 kPa full-scale range, ratiometric voltage output (20–50 mV span at 3.0 V supply), ±1.0 %VFSS linearity, and −40 °C to +125 °C operating temperature. It features a durable epoxy unibody package (Case 344-15), 4-pin SMT footprint, and is designed for integration into external temperature compensation and signal conditioning circuits in pneumatic and medical sensing systems.
For engineers reviewing the MPX10D datasheet, MPX10D pinout, MPX10D application, or MPX10D equivalent, this page delivers verified technical context, exact pin roles, real-world use cases, and validated alternative options - all grounded in NXP's Rev. 15 product data sheet and official package documentation.
Technical Context
The MPX10D implements a single-element silicon shear-stress strain gauge integrated directly onto the diaphragm, eliminating thermal expansion mismatch errors common in bonded-gauge sensors. Its ratiometric output scales linearly with supply voltage (3.0–6.0 VDC), enabling direct interface with ADCs without independent reference voltage.
It operates exclusively in gauge configuration (P1 > P2), with pressure applied to the stainless steel cap side (identified per Table 8), and delivers differential analog output across +VOUT and –VOUT pins. No internal compensation circuitry is included - full temperature and offset calibration must be implemented externally.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full-Scale Pressure | 0–10 kPa gauge range - defines maximum measurable differential pressure before nonlinear error exceeds specification. |
| Output Span (VFSS) | 20–50 mV at 3.0 V supply - determines minimum ADC resolution required for <1% FS accuracy. |
| Linearity Error | ±1.0 %VFSS (end-point method) - sets worst-case deviation from ideal linear transfer function over full pressure range. |
| Supply Voltage Range | 3.0–6.0 VDC - defines compatible excitation rails; output scales ratiometrically, simplifying power domain interfacing. |
| Operating Temperature | −40 °C to +125 °C - enables deployment in industrial and automotive under-hood environments without derating. |
| Response Time | 1.0 ms (10%–90%) - supports dynamic pressure monitoring in fast-cycling pneumatic valves and robotics joints. |
| Offset Voltage | 0–35 mV at 0 kPa - requires external nulling or digital offset correction in signal chain design. |
Pinout & Package
Epoxy unibody surface-mount package (Case 344-15, SOT1772-1), 4-pin single-row layout with 1.27 mm pitch, optimized for reflow soldering and mechanical robustness in vibration-prone systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Common return path for supply and output; must be low-impedance to minimize offset drift. |
| +VOUT | Positive output terminal | Delivers voltage proportional to applied pressure relative to –VOUT; used with instrumentation amplifier inputs. |
| VS | Power supply input | Accepts 3.0–6.0 VDC; output magnitude scales directly with VS, enabling ratiometric ADC rejection of supply variation. |
| –VOUT | Negative output terminal | Differential complement to +VOUT; required for true differential readout to reject common-mode noise. |
Key Features
| Feature | Design Value |
|---|---|
| Patented silicon shear-stress strain gauge | Eliminates thermal expansion mismatch between gauge and diaphragm, reducing zero-point drift vs. bonded-gauge alternatives. |
| Ratiometric output | Enables direct connection to ratiometric ADCs without separate voltage reference, cutting BOM cost and layout complexity. |
| Gauge pressure configuration | Measures pressure relative to ambient atmosphere via P1 (stainless steel cap) side, simplifying porting in HVAC and medical devices. |
| Epoxy unibody construction | Provides hermetic-like environmental protection with high mechanical durability and compatibility with standard SMT reflow profiles. |
Applications
| Air Movement Control | Leak Detection |
|---|---|
Use Scenario: Monitoring airflow in HVAC ducts and fan assemblies to maintain setpoint velocity and detect filter clogging. IC Role / Device Role / Timing Role: Gauge pressure sensor measuring differential pressure across filters or orifices to infer volumetric flow rate. Use Value: Enables closed-loop fan speed control using only the MPX10D's 10 kPa range and 1 ms response - no external amplification needed for basic threshold detection. |
Use Scenario: Detecting pressure decay in sealed enclosures (e.g., medical gas lines, pneumatic actuators) over 1–60 second intervals. IC Role / Device Role / Timing Role: Low-drift gauge sensor capturing slow pressure changes; offset stability of ±0.5 %VFSS ensures reliable pass/fail decision after thermal settling. Use Value: Delivers repeatable sub-100 Pa resolution using its 3.5 mV/kPa sensitivity and stable 20–50 mV span - sufficient for ISO 13485-compliant medical leak testing. |
| Medical Diagnostics | Pneumatic Control Systems |
Use Scenario: Measuring respiratory airway pressure in portable ventilators and spirometers during inhalation/exhalation cycles. IC Role / Device Role / Timing Role: Primary pressure transducer converting patient airway pressure into analog voltage for microcontroller sampling at ≥100 Hz. Use Value: −40 °C to +125 °C rating allows operation inside compact, fanless enclosures; ratiometric output rejects battery voltage sag during extended field use. |
Use Scenario: Closed-loop position control of pneumatic cylinders via feedback of chamber pressure in factory automation valves. IC Role / Device Role / Timing Role: Embedded gauge sensor mounted on cylinder manifold to monitor actuation pressure and prevent over-pressurization. Use Value: Burst pressure rating of 100 kPa and overpressure limit of 75 kPa provide 7.5× safety margin over 10 kPa operating range - critical for industrial safety compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX10DP | Same die and electrical specs; differs only in Case 344C-01 package with part marking on pressure side instead of stainless steel cap. | Preferred when visual port identification is needed during assembly; identical performance in leak detection or airflow monitoring. | Select MPX10DP if board-level orientation verification or automated optical inspection (AOI) of pressure-side marking is required. |
| MPX2010DP | Includes on-chip temperature compensation and signal conditioning; 10 kPa range, but outputs 0.5–4.5 V ratiometric (not differential). | Suitable for drop-in replacement where analog output conditioning is impractical; not pin-compatible and requires different PCB layout. | Choose MPX2010DP only when eliminating external compensation circuitry justifies redesign - MPX10D retains full flexibility for custom calibration algorithms. |
Compared with MPX10DP, the MPX10D offers identical metrology but simpler mechanical identification; versus MPX2010DP, it trades integrated signal conditioning for full external calibration control - making MPX10D optimal for cost-sensitive, high-volume designs requiring custom temperature compensation.

FAQ
What is the pressure type and measurement range of the MPX10D?
The MPX10D is a gauge pressure sensor with a full-scale range of 0–10 kPa (0–1.45 PSI). It measures pressure relative to ambient atmospheric pressure on the stainless steel cap side (P1), and requires positive differential pressure (P1 > P2) for proper operation per NXP's specification.
Does the MPX10D include built-in temperature compensation?
No, the MPX10D is an uncompensated sensor. Its output exhibits temperature-dependent offset and full-scale span drift (TCVoff = ±15 μV/°C; TCVFSS = −0.22 to −0.16 %VFSS/°C), requiring external resistive networks or digital compensation - as detailed in NXP Application Note AN840.
What package type and pin configuration does the MPX10D use?
The MPX10D uses the epoxy unibody SMT package Case 344-15 (SOT1772-1), with four terminals in a single-row layout: Pin 1 = GND, Pin 2 = +VOUT, Pin 3 = VS, Pin 4 = –VOUT - confirmed in Table 3 and Figure 3 of the official datasheet.
Can the MPX10D be used for differential pressure measurement?
No - the MPX10D is specified and characterized exclusively as a gauge pressure sensor. For true differential pressure measurement (P1 vs. P2), NXP offers the MPX10DP variant with identical electrical specs but alternate port labeling, or dedicated differential parts like MPXV10GC6U.
What is the maximum supply voltage and current draw for the MPX10D?
The MPX10D operates from 3.0 VDC to 6.0 VDC, with a typical supply current of 6.0 mA at VS = 3.0 VDC. Exceeding 6.0 VDC risks self-heating-induced errors and violates absolute maximum ratings per Table 6 of the datasheet.
