Product details
Overview
MPX10GP 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 V supply), ±1.0 %VFSS linearity, and −40 °C to +125 °C operating temperature. It features a durable epoxy unibody package (Case 344B-01) and is designed for integration into external temperature compensation and signal conditioning networks in pneumatic and medical diagnostics systems.
For engineers reviewing the MPX10GP datasheet, MPX10GP pinout, MPX10GP application, or MPX10GP equivalent, this page delivers verified technical context, exact pin definitions, real-world use scenarios, and validated alternative options - all grounded in NXP's Rev. 15 product data sheet dated 22 April 2021.
Technical Context
The MPX10GP 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 simplified analog interface design when paired with a stable reference.
It operates exclusively in gauge configuration (P1 > P2), with the pressure side identified by the port-attached surface per Case 344B-01 mechanical drawing. Output impedance (750–1250 Ω) and input impedance (400–550 Ω) are specified to guide external amplifier selection and minimize loading effects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full-Scale Pressure | 10 kPa - defines maximum measurable differential pressure before nonlinear response or damage risk. |
| Output Span (VS = 3 V) | 20–50 mV - determines minimum ADC resolution required for 1% accuracy (e.g., ≥12-bit for 10 kPa full scale). |
| Linearity Error | ±1.0 %VFSS - worst-case deviation from end-point straight-line fit over 0–10 kPa, critical for calibration budgeting. |
| Supply Voltage Range | 3.0–6.0 VDC - ratiometric operation allows shared reference with ADC, but self-heating increases above 6 V. |
| Operating Temperature | −40 °C to +125 °C - supports industrial and automotive under-hood environments without internal compensation. |
| Response Time | 1.0 ms (10–90%) - enables real-time monitoring of fast pneumatic transients such as valve actuation or leak pulses. |
| Offset Voltage | 0–35 mV at 0 kPa - requires trimming or software nulling in signal chain to achieve zero-pressure baseline accuracy. |
Pinout & Package
Epoxy unibody package (Case 344B-01), surface-mount, 4-pin, port-attached pressure side. Dimensions per SOT1753-1 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Reference ground for both supply and output; must be low-impedance to minimize offset drift. |
| 2 | +VOUT | Positive bridge output terminal; connects to instrumentation amplifier non-inverting input. |
| 3 | VS | Excitation supply input; ratiometric scaling means output voltage ∝ VS × pressure. |
| 4 | –VOUT | Negative bridge output terminal; completes Wheatstone bridge measurement path. |
Key Features
| Feature | Design Value |
|---|---|
| Silicon shear-stress strain gauge | Eliminates thermal expansion mismatch between gauge and diaphragm, improving long-term stability vs. bonded gauges. |
| Ratiometric output | Enables direct interface with ratiometric ADCs or microcontroller references, removing need for independent voltage reference. |
| Gauge pressure configuration | Measures pressure relative to ambient atmosphere via port-attached side (P1), simplifying mounting in open-air systems. |
| Uncompensated architecture | Allows full customization of temperature compensation network (e.g., thermistor-based or digital lookup table) per system requirements. |
| Durable epoxy unibody | Provides mechanical robustness and environmental sealing for industrial pneumatics and medical devices exposed to vibration or humidity. |
Applications
| Air Movement Control | Leak Detection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX10D | Same 10 kPa range, identical pinout (GND/+VOUT/VS/–VOUT), but housed in Case 344-15 with stainless steel cap instead of port-attached epoxy unibody. | MPX10D uses stainless steel cap for P1 identification; better suited for high-vibration or washdown environments where port integrity is critical. | Select MPX10D if mechanical ruggedness or media isolation via metal cap is prioritized over port-based mounting flexibility. |
| MPXV10GC6U | Different package (SOT1854-1, Case 482A), 8-pin SOIC with 4 NC pins; same electrical specs but higher parasitic capacitance due to larger lead frame. | SOIC format enables through-hole or reflow-compatible PCB layout; NC pins simplify routing but increase board area vs. 4-pin SMT MPX10GP. | Choose MPXV10GC6U only when legacy SOIC footprint compatibility or manual prototyping convenience outweighs size and cost advantages of MPX10GP. |
Compared with MPX10D and MPXV10GC6U, the MPX10GP offers the smallest footprint and lowest unit cost among NXP's 10 kPa gauge sensors, with its port-attached unibody enabling direct hose or tube coupling - ideal for space-constrained medical and robotics designs requiring rapid pressure interface.

FAQ
What is the pressure type and measurement range of the MPX10GP?
The MPX10GP is a gauge pressure sensor with a full-scale range of 0 to 10 kPa (0 to 1.45 PSI). It measures pressure relative to ambient atmospheric pressure via the port-attached side (P1), as defined in NXP's Case 344B-01 mechanical specification. The device is not rated for absolute or differential configurations - only gauge operation is supported for MPX10GP.
Does the MPX10GP include built-in temperature compensation?
No, the MPX10GP is an uncompensated sensor. Its output exhibits temperature-dependent full-scale span (−0.22 to −0.16 %VFSS/°C) and offset (±15 μV/°C) drift, requiring external compensation via resistive networks or digital correction. NXP provides guidance in Application Note AN840 for designing custom compensation circuits across −40 °C to +125 °C.
What is the correct pinout and connection method for MPX10GP?
The MPX10GP has four pins in order: Pin 1 = GND, Pin 2 = +VOUT, Pin 3 = VS, Pin 4 = –VOUT - as confirmed in Table 5 of the Rev. 15 datasheet. It forms a Wheatstone bridge; VS supplies excitation, and the differential output (+VOUT to –VOUT) must be measured with a high-input-impedance amplifier (Zin = 400–550 Ω, Zout = 750–1250 Ω).
Can MPX10GP be used with a 5 V supply, and how does supply voltage affect output?
Yes, MPX10GP operates from 3.0 V to 6.0 V DC. Its output is ratiometric: full-scale span (20–50 mV) and offset (0–35 mV) scale linearly with VS. At 5 V, expect ~1.67× higher output than at 3 V (e.g., ~33–83 mV span), but self-heating error increases above 6 V - so 5 V is within safe, optimal range for improved SNR without thermal penalty.
What are the key reliability specifications for MPX10GP in long-term deployment?
MPX10GP specifies ±0.5 %VFSS offset stability after 1000 hours of pulsed pressure-temperature cycling, ±0.1 %VFSS pressure hysteresis (0–10 kPa), and ±0.5 %VFSS temperature hysteresis (−40 °C to +125 °C). Burst pressure is rated at 100 kPa and overpressure at 75 kPa - exceeding its 10 kPa operating range by 7.5×, ensuring margin against transient spikes in pneumatic systems.
