Product details
Overview
MPX12DP from NXP Semiconductors is a silicon piezoresistive gauge pressure sensor delivering ratiometric, linear voltage output proportional to applied differential pressure up to 10 kPa. It features uncompensated operation with ±0.5%VFSS linearity, 5.5 mV/kPa sensitivity, and operates from 3.0–6.0 Vdc supply. Used in pneumatic control systems where external temperature compensation and signal conditioning are integrated.
For engineers reviewing the MPX12DP datasheet, MPX12DP pinout, MPX12DP application, or MPX12DP equivalent, this page provides verified technical context, pin-level circuit roles, real-world use cases in medical diagnostics and robotics, and validated alternative options for design flexibility and supply continuity.
Technical Context
The MPX12DP implements a single-element silicon shear-stress strain gauge integrated directly into the diaphragm, eliminating thermal expansion mismatch errors common in bonded-gauge sensors. Its ratiometric output scales precisely with supply voltage, enabling direct interface with ADCs without separate reference circuits.
It is configured as a gauge-pressure device (P1 > P2), with pressure port on the side marked per Case 1320A-02 package outline. Output polarity is defined by +VOUT and –VOUT terminals, supporting differential readout to reject common-mode noise and offset drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–10 kPa full-scale gauge pressure - defines maximum measurable differential pressure before nonlinear response or damage risk. |
| Supply Voltage | 3.0–6.0 Vdc - operating range over which ratiometric output remains valid; self-heating error increases beyond 6.0 Vdc. |
| Full Scale Span | 45–70 mV at 10 kPa - actual output swing between min/max rated pressure, used to size downstream amplification gain. |
| Sensitivity | 5.5 mV/kPa typical - enables resolution of ~180 Pa per mV, critical for low-pressure air movement detection. |
| Linearity Error | ±0.5%VFSS (end-point method) - worst-case deviation from ideal linear transfer function across 0–10 kPa range. |
| Operating Temp | −40 °C to +125 °C - supports industrial and automotive under-hood environments without internal compensation. |
| Response Time | 1.0 ms (10%–90%) - suitable for dynamic pressure monitoring in robotics and leak detection systems. |
Pinout & Package
MPX12DP is housed in the MPAK package (Case 1320A-02), a 4-pin surface-mount chip carrier with integrated pressure port on the P1 side. The package provides mechanical isolation via silicone gel while transmitting pressure to the silicon diaphragm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Reference ground node | Common return path for supply current and output reference; must be low-impedance to minimize offset error. |
| +VOUT | Differential output positive | High-side output terminal; voltage rises with increasing P1 pressure relative to P2 (vacuum side). |
| VS | Power supply input | Excitation source for piezoresistive bridge; output scales ratiometrically with this voltage. |
| –VOUT | Differential output negative | Low-side output terminal; completes Wheatstone bridge output pair for noise-rejecting differential measurement. |
Key Features
| Feature | Design Value |
|---|---|
| Patented silicon shear-stress strain gauge | Eliminates thermal expansion mismatch between gauge and diaphragm, reducing zero-shift error vs. bonded-gauge alternatives. |
| Ratiometric output | Output voltage scales linearly with VS, allowing direct connection to SAR ADCs without precision voltage references. |
| Gauge-port configuration | Single pressure port (P1) referenced to ambient/vacuum (P2), enabling cost-effective differential or gauge pressure sensing in HVAC and medical devices. |
| Uncompensated architecture | Enables system-level optimization: designers implement custom temperature compensation networks or digital correction algorithms tailored to specific application profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX2010D | Compensated, 10 kPa full-scale, includes on-chip temperature compensation and trimmed offset; higher cost, same MPAK package. | Reduces external component count for designs lacking resources for custom compensation networks. | Select MPX2010D when minimizing BOM count and time-to-market outweighs cost sensitivity and calibration flexibility. |
| MPX5010DP | 10 kPa full-scale, temperature-compensated and calibrated; wider supply range (4.75–5.25 Vdc); higher output (≈100 mV span). | Designed for plug-and-play integration with 5 V microcontrollers; requires no external signal conditioning for basic readout. | Choose MPX5010DP for rapid prototyping or volume production where guaranteed factory calibration and fixed supply simplify design validation. |
Compared with MPX12DP, MPX2010D offers integrated compensation at higher unit cost but identical footprint, while MPX5010DP delivers calibrated 5 V-compatible output with reduced design effort-both serve as functional alternatives when external compensation is not required or feasible.

FAQ
What is the pressure port configuration of the MPX12DP?
The MPX12DP is a gauge-pressure sensor with a single pressure port on the P1 side (identified by the port attachment on Case 1320A-02), referenced to ambient or vacuum (P2). It measures differential pressure where P1 > P2, and is not rated for absolute or sealed-reference operation. This configuration is confirmed in Table 5 and Figure 2 of the MPX12 datasheet.
Does the MPX12DP require external temperature compensation?
Yes, the MPX12DP is an uncompensated sensor: its full-scale span has a temperature coefficient of −0.16 to −0.22 %VFSS/°C and offset varies ±15 μV/°C. External compensation-using resistive networks or digital correction-is required for stable performance across −40 °C to +125 °C. Application Note AN840 documents proven methods for MPX12DP compensation.
What is the meaning of "ratiometric" for the MPX12DP output?
"Ratiometric" means the MPX12DP output voltage scales linearly with its supply voltage (VS). For example, if VFSS = 60 mV at VS = 3.0 V, it will be ≈120 mV at VS = 6.0 V. This allows direct interfacing with microcontroller ADCs using the same VS as the ADC reference, eliminating need for a separate precision voltage reference and improving system-level accuracy.
Can the MPX12DP be used with media other than dry clean air?
No-the MPX12DP's qualification, reliability testing, and specified operating characteristics assume dry clean air as the pressure medium. Exposure to moisture, oils, solvents, or corrosive gases may degrade silicone gel isolation, cause drift, or permanently damage the die. For non-air media, consult NXP's AN3728 or contact factory support before deployment; MPX12DP is not rated for such use.
What is the burst pressure rating of the MPX12DP?
The MPX12DP has a burst pressure rating of 100 kPa (Table 3), meaning it can withstand short-term overpressure up to that level without mechanical failure. However, its maximum recommended operating pressure is 10 kPa, and overpressure beyond 75 kPa (Pmax) risks permanent performance degradation-even if below burst limit. Sustained operation above 10 kPa voids specification compliance.
