Product details
Overview
MPX5100DP from NXP Semiconductors is a monolithic silicon piezoresistive differential pressure sensor with 0–100 kPa full-scale range, ±2.5% accuracy over 0–85 °C, ratiometric 4.75–5.25 V supply operation, and 45 mV/kPa sensitivity. It delivers a high-level analog output (0.088–4.813 V) proportional to applied differential pressure and is used in microcontroller-based pump control, medical patient monitoring, and industrial process sensing.
For engineers reviewing the MPX5100DP datasheet, MPX5100DP pinout, MPX5100DP application, or MPX5100DP equivalent, key selection considerations include its unibody epoxy package, dual-port differential configuration, on-chip temperature compensation, and compatibility with 5 V A/D interfaces in embedded sensing systems.
Technical Context
The MPX5100DP integrates a patented silicon shear-stress strain gauge with thin-film metallization and bipolar processing to generate a linear, temperature-compensated analog voltage output. Its internal architecture includes two gain stages and ground-reference shift circuitry, enabling stable operation across –40 to +125 °C.
It operates ratiometrically - output voltage scales directly with supply voltage (VS), supporting accurate measurement without external reference. The device uses fluorosilicone gel encapsulation to isolate the die while transmitting pressure to the diaphragm, and requires dry air as the pressure medium for specified performance and reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 100 kPa differential - supports precise low-pressure measurement in HVAC, medical, and industrial flow control. |
| Accuracy | ±2.5% of full-scale span (VFSS) over 0–85 °C - includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset contributions. |
| Supply Voltage | 4.75–5.25 VDC - ratiometric operation ensures output scaling matches VS, simplifying A/D conversion in 5 V systems. |
| Output Voltage Range | 0.088 V (min offset) to 4.813 V (max full-scale) at VS = 5.0 V - provides >4.5 V span for high SNR into 12-bit+ ADCs. |
| Sensitivity | 45 mV/kPa - enables direct interpretation of output change per kPa without gain calibration in many applications. |
| Response Time | 1.0 ms (10% to 90%) - suitable for dynamic pressure monitoring including motor/pump transient detection. |
| Operating Temp. | –40 to +125 °C - wide range supports under-hood automotive, industrial, and medical equipment deployment. |
Pinout & Package
MPX5100DP uses the 6-lead unibody package (case 98ASB42797B), featuring an epoxy-encapsulated silicon die with dual pressure ports and fluorosilicone gel protection. The package is surface-mountable with a defined footprint per NXP's mechanical drawings.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Analog output voltage proportional to differential pressure - connects directly to MCU A/D input with optional RC filtering. |
| 2 | GND | Analog ground reference - must be tied to system AGND with low-impedance path to minimize noise coupling. |
| 3 | VS | Positive supply input (4.75–5.25 V) - requires local 0.01 µF + 1.0 µF decoupling per Figure 7 of datasheet. |
| 4–6 | DNC | Internal connections only - must remain unconnected; no PCB traces or vias allowed on these pads. |
Key Features
| Feature | Design Value |
|---|---|
| Piezoresistive silicon shear-stress gauge | Enables high stability and low hysteresis vs. conventional Wheatstone bridges, improving long-term repeatability in cyclic pressure applications. |
| On-chip temperature compensation | Eliminates need for external thermistor or digital correction - maintains ±2.5% VFSS accuracy across 0–85 °C without firmware overhead. |
| Dual-port differential configuration | Allows true differential pressure measurement (P1 > P2) with isolated media paths - essential for flow, filter monitoring, and leak detection. |
| Epoxy unibody construction | Provides mechanical robustness and environmental sealing in non-corrosive gas/air applications, reducing assembly complexity vs. gasketed modules. |
| Ratiometric output | Output voltage scales linearly with VS - enables use with shared 5 V rail and eliminates need for precision voltage references in cost-sensitive designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5100DP | Same 0–100 kPa range and ±2.5% accuracy, but in 8-lead small-outline package (98ASA99255D) with different pinout and port orientation. | Designed for space-constrained PCB layouts requiring dual-port side-entry; lacks unibody epoxy ruggedness of MPX5100DP. | Select MPXV5100DP when board area is limited and reflow-compatible SMT placement is required; verify port alignment and decoupling layout per AN1646. |
| MPX5010DP | Lower 0–10 kPa range, same unibody package and pinout, ±2.5% accuracy, but reduced sensitivity (450 mV/kPa) and narrower temp range (0–85 °C). | Optimized for high-resolution low-pressure applications like respiratory flow meters - not suitable for 100 kPa system monitoring. | Choose MPX5010DP only when sub-10 kPa resolution is critical; MPX5100DP remains preferred for general-purpose 0–100 kPa differential sensing. |
Compared with MPXV5100DP, MPX5100DP offers superior mechanical robustness and simplified layout due to its unibody construction and 3-active-pin interface; compared with MPX5010DP, it extends full-scale range tenfold while maintaining identical accuracy and interface compatibility - making MPX5100DP the optimal choice for mid-range industrial and medical differential pressure tasks.

FAQ
What is the maximum pressure rating for MPX5100DP?
The MPX5100DP has a maximum pressure rating of 400 kPa, well above its 0–100 kPa full-scale operating range. This overpressure capability protects the sensor from transient spikes during system startup, valve switching, or fault conditions without permanent damage or calibration shift - a key reliability feature confirmed in Table 3 of the MPX5100 Rev. 14 datasheet.
Does MPX5100DP require external temperature compensation?
No, MPX5100DP does not require external temperature compensation. It features fully integrated on-chip temperature compensation and calibration, delivering ±2.5% VFSS accuracy over 0–85 °C without additional components or firmware correction - a core design advantage documented in Section 3 and Figure 5 of the MPX5100 datasheet.
Can MPX5100DP be used with a 3.3 V microcontroller ADC?
MPX5100DP is specified for 4.75–5.25 V supply only and is not rated for 3.3 V operation. Using it with a 3.3 V rail violates absolute maximum ratings and degrades accuracy, output swing, and stability. For 3.3 V systems, consider NXP's MPXV7002 or MP3V5050 - MPX5100DP must be powered from a dedicated 5 V source even when interfacing with 3.3 V MCUs.
What is the pressure media compatibility of MPX5100DP?
MPX5100DP is qualified for use with dry air as the pressure medium. Other media - including liquids, humid air, oils, or corrosive gases - may degrade fluorosilicone gel integrity or cause long-term drift. NXP explicitly states that non-dry-air media "may have adverse effects on sensor performance and long-term reliability," and recommends contacting factory support before qualifying MPX5100DP in alternative media.
How is the differential port orientation identified on MPX5100DP?
For MPX5100DP, the Pressure (P1) side is identified by the side bearing the part marking (e.g., "MPX5100DP") per Table 4.1 in the datasheet. P1 must be connected to the higher-pressure port and P2 to the lower-pressure or reference port; applying reverse differential pressure (P2 > P1) is not supported and may affect accuracy or longevity of the MPX5100DP.
