Product details
Overview
MPX2102ASX from NXP Semiconductors (formerly Freescale) is a silicon piezoresistive absolute pressure sensor with on-chip temperature compensation, delivering a ratiometric 40 mV full-scale output at 10 V supply across 0–100 kPa (0–14.5 psi), used in barometric sensing and medical diagnostics where stable zero-point accuracy and low thermal drift are critical.
For engineers reviewing the MPX2102ASX datasheet, MPX2102ASX pinout, MPX2102ASX application, or MPX2102ASX equivalent, this page provides verified technical context, calibrated performance specs, package-validated pin functions, real-world use cases, and two confirmed alternative parts for pressure-sensing system design and BOM flexibility.
Technical Context
The MPX2102ASX integrates a monolithic silicon diaphragm with laser-trimmed thin-film resistor networks for span and offset calibration. Its internal circuitry includes on-chip temperature compensation over 0°C to +85°C, enabling direct analog voltage output without external signal conditioning.
It operates ratiometrically with 10 V ±6 V excitation, exhibits 1.0 ms response time (10%–90%), and maintains ±0.5%VFSS linearity using end-point straight-line fit. The device uses dry air as specified pressure media and requires P1-side port identification per Case 344F mechanical marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa absolute - defines full-scale operating envelope for barometric and vacuum-referenced measurements |
| Full Scale Span | 40 mV typical at VS = 10 VDC - enables direct ADC interface with 12-bit resolution down to ~10 Pa LSB |
| Supply Voltage | 10 VDC nominal (6–16 V range) - supports ratiometric operation; output scales linearly with supply variation |
| Linearity Error | ±1.0%VFSS (end-point method) - ensures predictable error budget in closed-loop control and calibration-critical systems |
| Temperature Range | −40°C to +125°C operating - validated for industrial and automotive under-hood environments |
| Response Time | 1.0 ms (10%–90%) - suitable for dynamic pressure monitoring in pump cycling and robotic actuation |
| Offset Voltage | −2.0 to +2.0 mV at min pressure - specifies zero-pressure baseline tolerance affecting system nulling requirements |
Pinout & Package
MPX2102ASX uses the Unibody Package Case 344F - a stainless-steel-capped, port-marked, 4-pin surface-mount housing with silicone gel isolation of the die and wire bonds. Dimensions: 27.43–28.45 mm × 18.80–19.30 mm × 16.00–16.51 mm (L×B×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | GND | Ground reference for both supply and output; must be low-impedance to minimize common-mode noise |
| Pin 2 | V(+)OUT | Positive differential output terminal; voltage increases with applied absolute pressure on P1 side |
| Pin 3 | VS | Supply input (6–16 VDC); powers internal Wheatstone bridge and compensation circuitry |
| Pin 4 | V(−)OUT | Negative differential output terminal; completes bridge output path; referenced to GND |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over 0°C to +85°C - eliminates need for external thermistor or digital correction in embedded systems |
| Laser-trimmed calibration | Factory-set span and offset - reduces production test time and enables single-point system calibration |
| Differential output architecture | Two complementary output pins (V+OUT/V−OUT) - improves noise immunity and enables instrumentation amplifier interfacing |
| Stainless steel port-marked case | Case 344F mechanical identifier - ensures unambiguous P1-side orientation during automated assembly |
| Dry-air media qualification | Specified performance based on dry air - informs material compatibility decisions for non-standard gas media |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5100AP | Wider 0–100 kPa range but 50 mV FS output; integrated signal conditioning; requires 5 V supply | Higher output sensitivity eases ADC drive but lacks MPX2102ASX's 10 V ratiometric flexibility | Select when system uses 5 V rails and needs reduced external amplification |
| MPXM2102AS | Same 0–100 kPa range and 40 mV FS; MPAK package (Case 1320A); port-attached P1 side identification | Smaller footprint and tape-and-reel availability suit high-volume SMT lines; different mechanical mounting | Select when board space is constrained and automated placement requires MPAK form factor |
Compared with MPX2102ASX, MPX5100AP offers higher output and built-in amplification but sacrifices supply voltage flexibility, while MPXM2102AS retains identical electrical specs in a smaller, port-attached package-making it ideal for space-constrained, high-throughput manufacturing where Case 344F orientation verification is impractical.

FAQ
What is the pressure type and range supported by the MPX2102ASX?
The MPX2102ASX is an absolute pressure sensor with a specified range of 0–100 kPa (0–14.5 psi). It contains an internal vacuum reference, so its output voltage decreases as vacuum is applied to the P1 port. This makes MPX2102ASX suitable for barometric, altimeter, and sealed-system pressure monitoring where ambient-referenced measurements are not required.
How is the P1 (pressure) side identified on the MPX2102ASX package?
Per Freescale documentation, the MPX2102ASX uses Case 344F packaging, and the P1 side is identified by "Port Marking" - a visible marking adjacent to the pressure port on the package body. This distinguishes it from other variants like MPX2102A (stainless steel cap) or MPX2102GP (port attached), ensuring correct orientation during assembly and preventing reversed pressure application that could damage the sensor.
What supply voltage does the MPX2102ASX require, and is it ratiometric?
The MPX2102ASX operates with a supply voltage range of 6–16 VDC, with 10 VDC as the nominal excitation. It is explicitly ratiometric: its 40 mV full-scale output scales linearly with supply voltage, meaning output voltage = (4 mV/kPa) × pressure × (VS/10). This allows MPX2102ASX to maintain accuracy even with moderate supply rail variation, simplifying power design in battery-operated or unregulated systems.
Does the MPX2102ASX require external temperature compensation or calibration?
No - the MPX2102ASX features on-chip temperature compensation validated over 0°C to +85°C, and factory laser trimming sets both span and offset. Its datasheet specifies TcSpan ≤ ±2.0%VFSS and TcOffset ≤ ±1.0 mV across that range. Therefore, MPX2102ASX delivers usable accuracy without external thermistors, lookup tables, or multi-point calibration - reducing firmware overhead and BOM count in resource-limited designs.
What is the maximum pressure rating and overpressure tolerance of the MPX2102ASX?
The MPX2102ASX has a maximum rated pressure (P1 > P2) of 400 kPa, which is four times its full-scale range of 100 kPa. This overpressure tolerance protects against transient spikes during system startup, valve slamming, or pressure surges in pneumatic circuits. Exceeding 400 kPa may cause permanent degradation, so MPX2102ASX should be used with appropriate mechanical limiters or relief valves in high-risk environments.
