Product details
Overview
MPX5100AP from NXP Semiconductors is an absolute pressure sensor IC with monolithic silicon piezoresistive sensing element, on-chip temperature compensation, and ratiometric analog output. It delivers 4.7 V full-scale output at 100 kPa with ±2.5% accuracy over 0–85 °C, operates from 4.75–5.25 V supply, and draws 7 mA typical current. It is used in medical patient monitoring and industrial process control where dry-air-compatible, calibrated absolute pressure measurement is required.
For engineers reviewing the MPX5100AP datasheet, MPX5100AP pinout, MPX5100AP application, or MPX5100AP equivalent, this page provides verified technical context, validated pin functions, confirmed operating characteristics (including offset stability, response time, and sensitivity), and real-world application mapping for embedded microcontroller-based systems interfacing to A/D converters.
Technical Context
The MPX5100AP integrates a patented silicon shear-stress strain gauge with thin-film metallization and bipolar processing to generate a linear, temperature-compensated analog voltage output proportional to absolute pressure (0–100 kPa). Its transfer function is VOUT = VS × (P × 0.009 − 0.095), with built-in gain stages and ground reference shift circuitry.
It features on-chip temperature compensation across 0–85 °C, uses fluorosilicone gel isolation for die protection, and is qualified for operation with dry air as pressure media. The device requires no external calibration and exhibits ±0.5%VFSS offset stability after 1000-hour pulsed pressure/temperature cycling.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5100GP | Small-outline 8-lead package (98ASB17757C); same 0–100 kPa range but gauge configuration; lacks absolute reference port. | Requires external vacuum reference for absolute-equivalent use; not drop-in for MPX5100AP's unibody mounting or port orientation. | Select only if board layout supports SOIC-8 and system design accommodates gauge-based absolute derivation. |
| MPX5700AP | Higher accuracy (±1.5%VFSS); wider temp range (−40 to +150 °C); same unibody 6-pin package and 0–100 kPa absolute range. | Valid for automotive under-hood and extended-temperature industrial use where tighter error budget is required. | Choose when enhanced accuracy and extended thermal performance justify cost premium over MPX5100AP. |
Compared with MPX5100AP, MPXV5100GP requires redesign of mechanical interface and signal conditioning due to gauge topology and SOIC packaging, while MPX5700AP offers direct drop-in replacement with improved accuracy and thermal margin-making it suitable for next-generation designs demanding higher confidence in absolute pressure readings.

FAQ
What is the pressure type and range supported by the MPX5100AP?
The MPX5100AP is an absolute pressure sensor with a specified range of 0 to 100 kPa. It measures pressure relative to full vacuum and is qualified for use with dry air as the pressure medium. Its transfer function is VOUT = VS × (P × 0.009 − 0.095), and it maintains ±2.5%VFSS accuracy across 0–85 °C ambient temperature. This makes MPX5100AP suitable for barometric sensing and sealed-system absolute pressure monitoring where atmospheric reference is not available.
Does the MPX5100AP require external calibration or trimming?
No, the MPX5100AP does not require external calibration or trimming. It integrates on-chip temperature compensation and factory calibration for offset, full-scale output, and span across its operating temperature range. The device delivers a ratiometric analog output that scales directly with supply voltage, eliminating the need for external thermistors, DACs, or software correction tables. All calibration data is embedded during manufacturing, so MPX5100AP operates as a plug-and-play sensor when powered within its 4.75–5.25 V supply range.
What are the valid supply voltage and current requirements for MPX5100AP?
The MPX5100AP operates from a nominal 5 V supply with a specified range of 4.75 V to 5.25 V DC. At VS = 5.0 V and TA = 25 °C, its typical supply current is 7.0 mA, with a maximum of 10 mA. The device is ratiometric, meaning its output voltage scales linearly with supply voltage-so variations within the specified excitation range do not degrade measurement accuracy. Decoupling requires a 1.0 μF bulk capacitor and a 0.01 μF ceramic capacitor placed close to the VS and GND pins, per NXP's recommended circuit in Figure 7 of the datasheet.
How is the MPX5100AP pinout configured and what are the unused pins?
The MPX5100AP uses a 6-lead unibody package (case 98ASB42796B) with three functional pins: Pin 1 is VOUT, Pin 2 is GND, and Pin 3 is VS. Pins 4, 5, and 6 are labeled DNC (Do Not Connect) and are internal device connections-these must remain unconnected to any external circuitry or ground. This pinout is explicitly documented in Figure 2 and Table 1 of the MPX5100 datasheet Rev. 14, and applies exclusively to the MPX5100AP/DP/GP variants in the unibody package.
Can MPX5100AP be used with pressure media other than dry air?
NXP specifies that MPX5100AP operating characteristics and long-term reliability are validated using dry air as the pressure medium. Media other than dry air-including moisture, oils, solvents, or corrosive gases-may degrade sensor performance or cause irreversible damage to the fluorosilicone gel, die, or wire bonds. For non-dry-air applications, NXP recommends contacting factory support to evaluate media compatibility. Using unqualified media voids warranty and may result in drift, offset shift, or premature failure of the MPX5100AP.
