Product details
Overview
MPXM12GS from NXP Semiconductors is a silicon piezoresistive gauge pressure sensor delivering ratiometric, linear voltage output proportional to applied differential pressure (P1 > P2) up to 10 kPa. It features 45–70 mV full-scale span at 3.0 V supply, ±0.1%VFSS pressure hysteresis, and operates across −40 °C to +125 °C. Used in pneumatic control systems where external temperature compensation and signal conditioning are integrated.
For engineers reviewing the MPXM12GS datasheet, MPXM12GS pinout, MPXM12GS application, or MPXM12GS equivalent, this page provides verified technical context, pin-level circuit roles, real-world use-value mapping, and validated alternative options for uncompensated low-pressure sensing in industrial and medical diagnostics designs.
Technical Context
The MPXM12GS implements a single-element silicon shear-stress strain gauge integrated monolithically into a silicon diaphragm, eliminating thermal expansion mismatch errors common in bonded-gauge sensors. Its ratiometric output scales directly with supply voltage (3.0–6.0 Vdc), enabling simplified analog front-end design when referenced to the same excitation source.
It is configured as a gauge-pressure device with dedicated P1 (ported, gel-isolated side) and P2 (vacuum-reference side), requiring mechanical mounting that exposes only the ported surface to measured pressure. Output is differential (+VOUT and –VOUT), supporting noise-rejecting instrumentation amplifier interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–10 kPa gauge (P1 > P2); supports air movement and leak detection down to ~1.45 PSI full scale. |
| Full Scale Span | 45–70 mV at VS = 3.0 Vdc; defines usable analog output swing before amplification or ADC scaling. |
| Supply Voltage | 3.0–6.0 Vdc; ratiometric operation ensures output tracking with supply variations, easing reference stability requirements. |
| Linearity Error | −0.5 to +5.0 %VFSS (end-point fit); sets worst-case deviation budget for calibrated pressure measurement systems. |
| Operating Temp | −40 °C to +125 °C; enables deployment in engine bays, HVAC ducts, and portable medical devices without active thermal management. |
| Response Time | 1.0 ms (10%–90%); suitable for dynamic airflow monitoring and closed-loop pneumatic actuation feedback. |
| Offset Voltage | 0–35 mV at 0 kPa; requires trimming or software nulling in high-accuracy applications. |
Pinout & Package
MPXM12GS uses the MPAK package (Case 1320A-02), a 4-pin surface-mount chip carrier with a pressure port on the P1 side. The package is designed for direct PCB mounting with silicone gel protection over the die and wire bonds.
| 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 | Differential output positive | High-side output terminal; used with –VOUT to reject common-mode noise in instrumentation circuits. |
| VS | Power supply input | Excitation source for ratiometric operation; also powers internal Wheatstone bridge. |
| –VOUT | Differential output negative | Low-side output terminal; completes differential pair for precision gain stages or ADC inputs. |
Key Features
| Feature | Design Value |
|---|---|
| Patented silicon shear-stress strain gauge | Monolithic integration eliminates thermal expansion mismatch, improving long-term zero stability vs. bonded gauges. |
| Ratiometric output | Output voltage scales linearly with VS, allowing shared reference for excitation and ADC-reducing component count and drift sensitivity. |
| Gauge-port configuration | Single pressure port (P1 side) enables simple mechanical integration into air ducts, catheters, or sealed enclosures with ambient vacuum reference. |
| Uncompensated architecture | Enables customer-specific temperature compensation and calibration-ideal for OEMs integrating custom signal chains or digital correction algorithms. |
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 |
|---|---|---|---|
| MPXV12GP | Discontinued NXP part; identical 10 kPa gauge range and MPAK-4 package but with different internal trimming and legacy marking. | Legacy designs only; no new production support or long-term availability assurance. | Select MPXM12GS for new designs requiring guaranteed supply and updated qualification per Rev. 12 datasheet. |
| MPXH6115A | Compensated, 15 kPa absolute pressure sensor in SO-8; includes on-chip temperature compensation and signal conditioning. | Requires no external compensation network but lacks differential/gauge flexibility and has higher cost and larger footprint. | Choose MPXM12GS when external compensation is preferred for cost-sensitive, space-constrained, or custom-calibrated systems. |
Compared with MPXV12GP, MPXM12GS offers current production status and documented revision control; versus MPXH6115A, it trades built-in compensation for lower BOM cost, smaller MPAK footprint, and design flexibility in temperature compensation topology.

FAQ
What is the pressure port configuration of the MPXM12GS?
The MPXM12GS is a gauge-pressure sensor with a single pressure port on the P1 side (identified by the physical port attachment on Case 1320A-02). The P2 side serves as the vacuum reference. This configuration requires the ported side to be exposed to the measured pressure while the opposite side remains at ambient or sealed vacuum-critical for accurate differential measurement in applications like leak detection or airflow monitoring using MPXM12GS.
Does the MPXM12GS require external temperature compensation?
Yes-the MPXM12GS is an uncompensated sensor, meaning its output exhibits temperature-dependent full-scale span and offset drift (e.g., TCVFSS = −0.22 to −0.16 %VFSS/°C). External compensation-using resistive networks, microcontroller-based lookup tables, or analog circuitry-is required for stable accuracy across −40 °C to +125 °C. Application Note AN840 documents proven methods for implementing such compensation specifically for MPXM12GS and related variants.
What is the maximum supply voltage for the MPXM12GS?
The MPXM12GS supports a supply voltage range of 3.0 Vdc to 6.0 Vdc, with specified operating characteristics validated at 3.0 Vdc. Operating above 6.0 Vdc risks permanent damage per Absolute Maximum Ratings. At 6.0 Vdc, output span increases proportionally (ratiometric behavior), but self-heating may introduce additional error-so 3.0–5.0 Vdc is recommended for optimal stability. All performance data in the MPXM12GS datasheet assumes VS within this validated range.
Can the MPXM12GS be used for absolute pressure measurement?
No-the MPXM12GS is explicitly designed and characterized as a gauge-pressure sensor (P1 > P2), with its P2 side intended as a vacuum reference. It lacks internal absolute pressure reference structures or calibration. For absolute pressure measurement, NXP offers alternatives like the MPXH6115A series-but those differ in package, compensation, and electrical interface. Using MPXM12GS in absolute mode would yield uncalibrated, temperature-sensitive results not supported by its datasheet specifications.
What is the warm-up time specification for the MPXM12GS?
The MPXM12GS has a maximum warm-up time of 20 ms-the time required after power-on for the output voltage to stabilize within its specified tolerance under constant pressure and temperature conditions. This fast settling supports high-throughput test systems and responsive closed-loop controls. Warm-up time is measured with pressure stabilized prior to power application, and performance assumes VS ≥ 3.0 Vdc and TA = 25 °C; actual behavior may vary slightly at temperature extremes but remains within system-level timing budgets when using MPXM12GS.
