Product details
Overview
MPXM2051GS from NXP Semiconductors is a gauge-type silicon piezoresistive pressure sensor delivering ratiometric voltage output proportional to applied pressure, with full-scale range of 0–50 kPa, ±0.3 %VFSS linearity, and on-chip temperature compensation over 0 °C to +85 °C. It serves as a primary analog sensing element in closed-loop pressure monitoring systems for medical diagnostics and industrial pump control.
For engineers reviewing the MPXM2051GS datasheet, MPXM2051GS pinout, MPXM2051GS application, or MPXM2051GS equivalent, this page provides verified technical context, calibrated performance parameters, package-validated terminal roles, and application-specific design value - all tied explicitly to the MPXM2051GST1 variant in MPAK (SOT1673-1) packaging.
Technical Context
The MPXM2051GS integrates a monolithic silicon diaphragm with embedded strain gauges and thin-film resistor networks, laser-trimmed for span/offset calibration and temperature compensation. Its differential Wheatstone bridge architecture delivers ratiometric output referenced to supply voltage (VS), enabling direct interface with ADCs without external reference scaling.
It operates as a gauge sensor with P1 (pressure side) exposed via ported MPAK package and P2 (vacuum side) sealed; output polarity is defined by P1 > P2 pressure differential. The device exhibits 1.0 ms response time, ±0.1 %VFSS pressure hysteresis, and stable offset within ±0.5 %VFSS after 1000-hour stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full-scale pressure range | 0–50 kPa - defines usable linear sensing window for low-pressure applications like non-invasive blood pressure or liquid level detection. |
| Output type | Differential ratiometric voltage - +VOUT and –VOUT provide bridge output directly scalable to VS, simplifying analog front-end design. |
| Linearity error | ±0.3 %VFSS (end-point method) - ensures high accuracy across full scale without software correction in cost-sensitive systems. |
| Temperature compensation | 0 °C to +85 °C - enables reliable operation in medical and industrial environments without external thermal management. |
| Response time | 1.0 ms (10%–90%) - supports dynamic pressure monitoring in robotics and motor control feedback loops. |
| Supply voltage range | 10–16 Vdc - compatible with standard industrial 12 V rails and tolerant of minor fluctuations without output drift. |
| Offset voltage | ±1.0 mV at 0 kPa - enables precise zero-pressure baseline setting in calibration-critical applications. |
Pinout & Package
The MPXM2051GS is housed in an MPAK package (Case 1320A, SOT1673-1), featuring a ported gauge configuration with silicone-gel-isolated die and lead-frame construction optimized for media compatibility with dry clean air.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Reference ground | Common return path for supply and output circuitry; must be low-impedance to maintain ratiometric accuracy. |
| +VOUT | Bridge output positive | High-side output of Wheatstone bridge; used with –VOUT to extract differential signal rejecting common-mode noise. |
| VS | Power supply input | Excitation source for piezoresistive bridge; output scales linearly with VS, enabling supply-referenced measurement. |
| –VOUT | Bridge output negative | Low-side output of Wheatstone bridge; paired with +VOUT to deliver true differential voltage proportional to pressure. |
Key Features
| Feature | Design Value |
|---|---|
| Gauge ported configuration | Enables direct atmospheric reference for pressure-to-level conversion without vacuum plumbing or differential tubing. |
| On-chip temperature compensation | Eliminates need for external thermistor networks or digital compensation algorithms in 0–85 °C operating range. |
| Laser-trimmed span and offset | Reduces factory calibration effort and ensures consistent sensitivity (0.8 mV/kPa) and zero-point accuracy across production lots. |
| Ratiometric output | Allows use with unregulated 12 V supplies and simplifies system-level accuracy by tracking supply variations in both excitation and measurement. |
| MPAK surface-mount package | Supports automated assembly and provides mechanical robustness for integration into compact medical or robotic enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5050GP | Same 50 kPa full-scale range but uses SOIC-8 package with integrated signal conditioning; outputs single-ended 0.2–4.7 V. | Requires no external amplifier but lacks differential output and has higher minimum supply (4.75 V). | Select when board space permits SOIC-8 and system requires simplified analog output without instrumentation amp stage. |
| SDX100G2 | 100 kPa range, same MPAK package and pinout; ±0.25 %VFSS linearity; 0–85 °C compensation. | Higher pressure capability suits HVAC or compressed air monitoring where 50 kPa is insufficient. | Select when application requires headroom above 50 kPa while retaining identical footprint and calibration workflow. |
Compared with MPXM2051GS, MPXV5050GP trades differential output and ratiometric flexibility for integrated signal conditioning, while SDX100G2 extends pressure range within the same MPAK form factor - making MPXM2051GS optimal for cost-sensitive, low-pressure, differential-readout designs requiring tight linearity and proven medical qualification.

FAQ
What is the operating temperature range for the MPXM2051GS?
The MPXM2051GS is temperature-compensated from 0 °C to +85 °C, with full performance specifications guaranteed across that range. Its maximum operating temperature is +125 °C, but accuracy parameters such as linearity and offset stability apply only within the compensated range. The MPXM2051GS maintains ±0.3 %VFSS linearity and ±1.0 mV offset over 0–85 °C, making it suitable for medical and industrial environments without external thermal regulation.
Does the MPXM2051GS require external calibration?
No, the MPXM2051GS does not require external calibration for basic operation. Each MPXM2051GS unit undergoes laser trimming during manufacturing for precise span and offset calibration, including on-chip temperature compensation. While system-level calibration may improve absolute accuracy in high-precision applications, the MPXM2051GS delivers specified linearity (±0.3 %VFSS) and offset (±1.0 mV) without additional trimming or compensation circuitry.
What is the pressure port configuration of the MPXM2051GS?
The MPXM2051GS uses a gauge configuration with a single pressure port on the P1 side (identified by the ported side of the MPAK package), while the P2 side is sealed to vacuum. This allows the MPXM2051GS to measure pressure relative to ambient atmosphere - ideal for level indicators, pump monitoring, and non-invasive blood pressure devices. The port is compatible with dry clean air; other media require factory consultation per AN3728.
Can the MPXM2051GS be used with a 5 V supply?
No, the MPXM2051GS requires a minimum supply voltage of 10 Vdc and operates up to 16 Vdc. Its ratiometric output is specified only within that range; using 5 V will result in insufficient bridge excitation, degraded signal-to-noise ratio, and potential noncompliance with linearity or offset specs. For 5 V systems, consider alternatives like MPXV5050GP, which is rated for 4.75–5.25 V operation.
What is the meaning of "ratiometric" in the MPXM2051GS datasheet?
"Ratiometric" means the MPXM2051GS output voltage scales linearly with its supply voltage (VS). For example, if VS changes from 10 V to 12 V, both the full-scale span (e.g., 40 mV) and offset (e.g., 0 mV) scale proportionally - preserving measurement accuracy even with supply variation. This allows the MPXM2051GS to interface directly with ratiometric ADCs, eliminating the need for a separate voltage reference and reducing system component count.
