Product details
Overview
MPX5100GP from NXP Semiconductors is a monolithic silicon piezoresistive pressure sensor in unibody epoxy package, configured for gauge pressure measurement (0 to 100 kPa), delivering ratiometric analog output (0.2–4.7 V at 5 V supply), ±2.5% full-scale accuracy over 0–85 °C, and 1 ms response time - used in medical patient monitoring and industrial pump control systems.
For engineers reviewing the MPX5100GP datasheet, MPX5100GP pinout, MPX5100GP application, or MPX5100GP equivalent, this page delivers verified technical context, validated pin functions, confirmed operating parameters, and real-world use-case implementation guidance for microcontroller-based pressure sensing designs.
Technical Context
The MPX5100GP integrates a patented silicon shear-stress strain gauge with on-chip thin-film temperature compensation and dual-stage gain amplification. Its output follows VOUT = VS × (0.009 × P + 0.04) ± (2.5% × VFSS × temperature multiplier), enabling direct A/D interfacing without external signal conditioning.
It operates ratiometrically across 4.75–5.25 V supply, draws ≤10 mA, and features internal decoupling support via recommended 1.0 μF/0.01 μF capacitor network. The unibody package isolates the die with fluorosilicone gel and uses dry air as qualified pressure media.
Key Specifications

Pinout & Package
MPX5100GP uses the 6-lead unibody epoxy package (case 98ASB42796B), with port on the same side as the marking. Pins 4–6 are internal connections and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Analog output voltage proportional to applied gauge pressure - directly interfaces to MCU ADC input. |
| 2 | GND | Ground reference for both supply and output - requires low-impedance connection to minimize noise coupling. |
| 3 | VS | Positive supply input (4.75–5.25 V) - must be decoupled with 1.0 μF and 0.01 μF capacitors per datasheet Figure 7. |
| 4 | DNC | Internal connection - no external trace, pad, or soldering allowed. |
| 5 | DNC | Internal connection - floating; must not be tied to GND or any other node. |
| 6 | DNC | Internal connection - electrically isolated from external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5100GP | Small-outline 8-lead package (98ASA99303D); identical electrical specs but different footprint and port orientation. | Requires PCB redesign due to 8-pin SOIC layout and side-port geometry - not drop-in compatible. | Select MPXV5100GP only when board space constraints favor SOIC or when side-port mounting is required. |
| MPX5010GP | Lower pressure range (0–10 kPa); same unibody package and pinout; ±2.5% accuracy retained. | Optimized for low-pressure applications like air flow sensing - insufficient for 100 kPa pump or process use cases. | Choose MPX5010GP only when target pressure stays below 15 kPa and higher resolution at low end is critical. |
Compared with MPX5100GP, MPXV5100GP offers identical sensing performance in a surface-mount SOIC package requiring layout change, while MPX5010GP trades pressure range for enhanced low-end sensitivity - neither is pin-compatible, and selection depends strictly on mechanical integration and pressure span requirements.

FAQ
What pressure type does the MPX5100GP measure?
The MPX5100GP measures gauge pressure - meaning it references ambient atmospheric pressure as zero. It has a single pressure port and outputs a voltage proportional to pressure applied relative to atmosphere, covering 0 to 100 kPa. This makes MPX5100GP suitable for applications such as tank level sensing, airflow monitoring, and pump discharge pressure feedback where absolute vacuum reference is not required.
What is the supply voltage range for reliable operation of the MPX5100GP?
The MPX5100GP operates reliably across a supply voltage range of 4.75 V to 5.25 V DC. Its ratiometric architecture ensures that output voltage scales linearly with supply voltage, maintaining measurement accuracy even with minor supply fluctuations. Operating outside this range may degrade accuracy or cause instability, and the datasheet specifies 5.0 V ± 0.25 V as the nominal condition for all key specifications including full-scale output and accuracy.
Does the MPX5100GP require external temperature compensation?
No, the MPX5100GP does not require external temperature compensation. It integrates on-chip temperature compensation circuitry that corrects for offset and span drift across 0 to 85 °C, contributing to its ±2.5% full-scale accuracy specification. This eliminates the need for external thermistors or calibration firmware - the MPX5100GP delivers factory-calibrated analog output directly usable by an MCU's ADC without additional signal conditioning.
Can the MPX5100GP be used with a 3.3 V microcontroller ADC?
The MPX5100GP is specified for 4.75–5.25 V supply and produces a 0.2–4.7 V output range under those conditions. Using it with a 3.3 V MCU ADC requires either level-shifting or supply regulation - direct connection risks exceeding the ADC's input voltage rating and damaging the MCU. For native 3.3 V compatibility, consider NXP's MPXV5004DP or MPXV7002DP, which are explicitly rated for 3.3 V operation and produce scaled output ranges.
What is the maximum pressure the MPX5100GP can withstand without damage?
The MPX5100GP has a maximum pressure rating of 400 kPa, as defined in its absolute maximum ratings table. Exceeding this pressure may cause permanent mechanical deformation or electrical degradation of the silicon sensing element. While the device is calibrated for 0–100 kPa operation, its overpressure capability provides safety margin during transient spikes - however, sustained exposure above 100 kPa will invalidate accuracy and long-term reliability claims for MPX5100GP.
