Product details
Overview
MPX4250D 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, consumes ≤10 mA, and maintains ±1.4 % accuracy across 0 °C to 85 °C - ideal for engine manifold pressure monitoring in automotive microcontroller-based systems.
For engineers reviewing the MPX4250D datasheet, MPX4250D pinout, MPX4250D application, or MPX4250D equivalent, key selection criteria include its unibody epoxy package (Case 867), 6-pin configuration with three DNC pins, differential/gauge dual-mode capability, and compatibility with A/D inputs requiring minimal external circuitry.
Technical Context
The MPX4250D integrates a piezoresistive sensing element with thin-film metallization and bipolar signal conditioning circuitry, including two gain stages and ground-reference shift circuitry. Its patented silicon shear-stress strain gauge enables high linearity and stability under mechanical stress.
On-chip temperature compensation operates across –40 °C to +125 °C, while the ratiometric transfer function VOUT = VCC × (P × 0.00369 + 0.04) ensures output scaling remains proportional to supply voltage, simplifying system-level calibration and reducing sensitivity to VCC drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 250 kPa full-scale - supports intake manifold and turbo boost pressure measurement up to ~36 psi. |
| Output Voltage Range | 0.204 V to 4.909 V at VCC = 5.1 V - directly interfaces 5 V A/D converters 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 | 4.85–5.35 Vdc - ratiometric operation ensures output scaling tracks VCC, easing power rail tolerance design. |
| Supply Current | 7.0–10.0 mAdc - enables low-power embedded designs with predictable current draw. |
| Response Time | 1.0 ms (10% to 90%) - suitable for dynamic pressure events such as throttle transients. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive environments. |
Pinout & Package
MPX4250D uses the unibody epoxy package Case 867 (orderable as 98ASB42793B), featuring a stainless steel cover and fluorosilicone die coating for environmental isolation and long-term reliability in harsh media.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Output voltage | Analog output proportional to applied differential/gauge pressure; requires 470 pF capacitor per Figure 5 for noise filtering. |
| GND | Ground reference | Common return path for supply and output; must be low-impedance to maintain offset stability. |
| VCC | Supply voltage input | 5.1 V ±0.25 V excitation source; powers internal amplifiers and compensation circuitry. |
| DNC | Do not connect | Pins 4, 5, and 6 are internally unused - must remain floating, not tied to GND or any trace. |
Key Features
| Feature | Design Value |
|---|---|
| Differential & gauge mode support | Single device configurable for either pressure type via port connection - reduces BOM count and layout variants. |
| Patented silicon shear-stress strain gauge | Improves mechanical robustness and long-term zero-point stability under vibration and thermal cycling. |
| On-chip temperature compensation | Eliminates need for external thermistor networks or software correction tables across –40 °C to +125 °C. |
| Durable epoxy unibody construction | Withstands exposure to oil, fuel vapor, and condensation in engine bay applications without gel degradation. |
| Ratiometric output transfer function | Enables direct interface to microcontroller ADCs referenced to same VCC rail - removes need for precision voltage references. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar pressure transducer 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 6-pin Case 867C package but different port geometry. | Designed for higher-pressure turbo and industrial hydraulic monitoring - not drop-in for 250 kPa systems due to reduced resolution. | Select MPX5700DP only when system pressure exceeds 250 kPa and higher dynamic range is required. |
| MPXV7025DP | 25 kPa full-scale range; 5 V ratiometric output; 8-pin SOIC package; integrated signal conditioning but no on-chip temperature compensation beyond 0–85 °C. | Targeted at low-pressure medical and lab instrumentation - lacks extended –40 °C to +125 °C qualification and unibody ruggedness. | Choose MPXV7025DP for cost-sensitive, low-range applications where automotive-grade temperature range and epoxy durability are not required. |
Compared with MPX5700DP and MPXV7025DP, the MPX4250D uniquely balances 250 kPa full-scale range, automotive-qualified temperature performance, unibody mechanical robustness, and factory calibration - making it optimal for engine management and industrial differential pressure sensing where reliability and accuracy are co-prioritized.

FAQ
What is the pressure media compatibility of the MPX4250D?
The MPX4250D is qualified for use with dry air as the pressure medium. Exposure to other media - including fuel, oil, or corrosive gases - may degrade long-term reliability or cause output drift. NXP explicitly states that non-dry-air media require factory consultation for compatibility validation. The fluorosilicone die coat provides limited chemical resistance, but the MPX4250D is not rated for direct contact with hydrocarbons or solvents. Always verify media compatibility before integration into final MPX4250D-based systems.
Does the MPX4250D require external temperature compensation circuitry?
No, the MPX4250D does not require external temperature compensation circuitry. It features fully integrated on-chip temperature compensation spanning –40 °C to +125 °C, covering both offset and span drift. This eliminates the need for external thermistors, lookup tables, or calibration algorithms in host firmware. The MPX4250D's internal compensation ensures ±1.4 % accuracy over 0 °C to 85 °C without additional hardware - a core design advantage confirmed in Section 8 of the official datasheet.
Can the MPX4250D be used in absolute pressure mode?
No, the MPX4250D is not specified for absolute pressure measurement. It is designed exclusively for differential and gauge pressure configurations, as stated in Section 2 ("Features") and Table 1 ("Ordering information"). Absolute pressure variants in this family carry distinct part numbers (e.g., MPX4250AP). The MPX4250D's port architecture and internal reference structure support only P1–P2 (differential) or P1–atmosphere (gauge) sensing - using it in absolute mode would yield undefined or inaccurate output.
What decoupling capacitors are required for stable operation of the MPX4250D?
The MPX4250D requires three decoupling capacitors per Figure 5 in the datasheet: a 1.0 µF bulk capacitor, a 0.01 µF ceramic capacitor, and a 470 pF output filter capacitor, all placed close to the device pins. These components suppress supply noise and reduce high-frequency output ripple, ensuring the MPX4250D meets its ±1.4 % accuracy specification. Omitting or substituting these values risks increased offset drift, reduced response fidelity, and failure to achieve published warm-up time (20 ms) and response time (1.0 ms) metrics.
Is the MPX4250D pin-compatible with earlier MPX4250 versions?
Yes, the MPX4250D is pin-compatible with the legacy MPX4250, as confirmed by the revision history noting "Revised 'MPX4250' to 'MPX4250D'" without changes to pinout, package, or electrical behavior. Both share identical Case 867 packaging, 6-pin layout, and functional pin assignments (VOUT, GND, VCC, and three DNC pins). The MPX4250D supersedes the MPX4250 with updated documentation and minor process refinements, but existing PCB layouts designed for MPX4250 will accept MPX4250D without modification.
