Product details
Overview
MPX4250DP from NXP Semiconductors is a monolithic silicon differential/gauge pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric analog output (0.204 V to 4.909 V) over 0–250 kPa full-scale range, operates from 4.85–5.35 V supply, draws ≤10 mA, and maintains ±1.4 % accuracy across 0 °C to 85 °C - ideal for engine manifold pressure monitoring in automotive ECU designs.
For engineers reviewing the MPX4250DP datasheet, MPX4250DP pinout, MPX4250DP application, or MPX4250DP equivalent, key selection considerations include its unibody epoxy package (Case 867C), 6-pin configuration with three DNC pins, differential pressure sensing capability, integrated temperature compensation up to +125 °C, and compatibility with microcontroller A/D inputs requiring minimal external circuitry.
Technical Context
The MPX4250DP integrates a piezoresistive silicon diaphragm with thin-film metallization and bipolar signal conditioning circuitry. Its architecture includes two gain stages, on-chip temperature compensation networks, and ground reference shift circuitry - enabling stable output without external calibration components.
It uses a patented silicon shear-stress strain gauge design and fluorosilicone die coating for environmental isolation. The device is ratiometric to VCC, exhibits 18.8 mV/kPa sensitivity, and achieves <1 ms response time with 20 ms warm-up time - optimized for real-time pressure feedback in closed-loop control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 250 kPa full-scale differential or gauge pressure - supports intake manifold and turbo boost sensing in ICE applications. |
| Output Voltage Range | 0.204 V to 4.909 V at VCC = 5.1 V - directly interfaces standard 5 V microcontroller ADCs without level-shifting. |
| Accuracy | ±1.4 % of full-scale span (VFSS) over 0 °C to 85 °C - includes linearity, TcOffset, TcSpan, and hysteresis contributions. |
| Supply Voltage | 4.85 V to 5.35 V DC - ratiometric operation ensures output scaling remains proportional to supply variations. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive environments with full functionality at extreme cold start and hot soak. |
| Response Time | 1.0 ms (10% to 90%) - enables dynamic pressure capture in fast-transient engine cycles. |
| Supply Current | 7.0 mA typical, ≤10 mA max - compatible with low-power ECU power budgets. |
Pinout & Package
MPX4250DP is housed in an epoxy unibody package (Case 867C, orderable as 98ASB42797B), featuring a stainless steel metal cover and RTV die bond for mechanical robustness and media isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Analog output voltage | Provides ratiometric 0.204–4.909 V signal proportional to applied pressure; requires 470 pF capacitor per Figure 5 for stability. |
| GND | Ground reference | System ground return path for both supply and output; must be low-impedance to minimize noise coupling. |
| VCC | Positive supply input | 5.1 V ±0.25 V excitation source; powers internal amplifiers and compensation circuitry. |
| DNC | No-connect terminal | Pins 4, 5, and 6 are internally unused - must remain floating, not tied to GND or any other node. |
Key Features
| Feature | Design Value |
|---|---|
| Differential & gauge pressure support | Single device supports both configurations via port assignment - eliminates need for separate part numbers in multi-sensor platforms. |
| On-chip temperature compensation | Compensated over –40 °C to +125 °C - removes requirement for external thermistor networks or software correction tables. |
| Patented silicon shear-stress strain gauge | Higher sensitivity and lower hysteresis vs. conventional piezoresistive elements - improves long-term repeatability in cyclic pressure applications. |
| Epoxy unibody construction | Durable, media-isolated housing with fluorosilicone die coat - resists vibration, moisture, and hydrocarbon exposure in engine bay environments. |
| Ratiometric output | Output scales linearly with VCC - simplifies system-level calibration when using shared MCU supply rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential/gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5700DP | Wider 0–700 kPa range; higher full-scale output (0.2–4.9 V); same Case 867C package and pinout. | Designed for higher-pressure turbo and industrial pneumatic systems; not drop-in for 250 kPa-critical calibration points. | Select MPX5700DP only if system pressure exceeds 250 kPa or requires extended overpressure margin (1000 kPa max). |
| MPXV7025DP | 25 kPa full-scale range; 0.2–4.8 V output; identical 6-pin Case 867C package but different transfer function slope (20 mV/kPa). | Optimized for low-pressure HVAC and medical flow sensing; lacks MPX4250DP's high-temperature compensation depth (–40 °C to +125 °C). | Choose MPXV7025DP for sub-100 kPa applications where higher resolution at low pressures outweighs wide-range accuracy needs. |
Compared with MPX5700DP and MPXV7025DP, the MPX4250DP uniquely balances 250 kPa full-scale range, ±1.4 % accuracy over automotive temperature extremes, and proven reliability in manifold pressure feedback - making it the optimal choice for mid-range ICE and hybrid powertrain pressure monitoring where precision and ruggedness intersect.

FAQ
What is the maximum rated pressure for the MPX4250DP?
The MPX4250DP has a maximum pressure rating of 1000 kPa (145 psi) - well above its 250 kPa full-scale operating range. This overpressure capability protects the sensor from transient spikes in intake manifold or turbo systems, ensuring long-term reliability without mechanical failure or permanent calibration shift.
Does the MPX4250DP require external calibration components?
No, the MPX4250DP does not require external calibration components. It integrates on-chip temperature compensation, gain staging, and factory calibration - delivering a ready-to-use ratiometric analog output. Only a 470 pF capacitor on VOUT and standard decoupling (1.0 µF + 0.01 µF) on VCC are needed per Figure 5 of the datasheet.
Can the MPX4250DP be used for absolute pressure measurements?
The MPX4250DP is configured as a differential or gauge pressure sensor - not absolute. Its design requires two pressure ports (P1 and P2); for absolute pressure sensing, one port must be sealed to vacuum reference. NXP does not specify or qualify the MPX4250DP for absolute use, and no vacuum-sealed variant exists in this family.
What is the warm-up time specification for the MPX4250DP?
The MPX4250DP has a specified warm-up time of 20 ms - defined as the time required after power-on for the output voltage to stabilize within its final value tolerance. This enables rapid system initialization in start-stop engine applications where pressure feedback must be valid within milliseconds of ECU boot.
Is the MPX4250DP compliant with AEC-Q200?
While the MPX4250DP was designed for automotive under-hood use and qualified across –40 °C to +125 °C operating temperature, NXP's official documentation does not list formal AEC-Q200 qualification for this specific part number. Customers requiring certified AEC-Q200 compliance should verify current status with NXP or select designated AEC-Q200 variants such as the MPX5xxxQ series.
