Product details
Overview
MPXM2102A from NXP Semiconductors (formerly Freescale) is an absolute pressure sensor IC with on-chip temperature compensation, delivering a ratiometric analog voltage output proportional to applied pressure in the 0–100 kPa range. It features 40 mV full-scale span (typ), ±0.6%VFSS linearity (MPXM2102A series), and operates from 10 VDC supply with 6.0 mA current draw. Used in barometric sensing and altimeter systems where stable low-pressure measurement is required.
For engineers reviewing the MPXM2102A datasheet, MPXM2102A pinout, MPXM2102A application, or MPXM2102A equivalent, key selection criteria include absolute pressure range (0–100 kPa), ratiometric 10 VDC excitation, on-chip temperature compensation over –40°C to +125°C, and MPAK package compatibility with PCB-level pressure porting.
Technical Context
The MPXM2102A integrates a monolithic silicon piezoresistive diaphragm with laser-trimmed thin-film resistor networks for span and offset calibration. Its internal circuitry includes on-chip temperature compensation circuitry that actively corrects for TcSpan (±2.0%VFSS) and TcOffset (±1.0 mV) across –40°C to +125°C.
It operates as a 4-pin ratiometric transducer: supply voltage directly scales output (40 mV @ 10 VDC), with output impedance of 1400–3000 Ω and response time of 1.0 ms (10%–90%). The device uses dry air as validated pressure media; non-standard media require factory consultation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa absolute; defines usable input range for barometric/altimeter applications without overpressure risk up to 400 kPa max. |
| Full Scale Span | 38.5–41.5 mV at 10 VDC supply; enables direct ADC interface with 12-bit resolution (≈2.4 mV/LSB) for ±0.5 kPa accuracy. |
| Linearity Error | ±0.6%VFSS (end-point method); contributes ≤±0.25 kPa error across full scale at 25°C, critical for precision altitude estimation. |
| Supply Voltage | 10 VDC typical, 16 VDC max; ratiometric operation ensures output scaling with supply, simplifying reference design but requiring stable excitation. |
| Temperature Range | –40°C to +125°C operating; supports automotive under-hood and industrial environments without external thermal management. |
| Response Time | 1.0 ms (10%–90%); suitable for dynamic pressure monitoring in pump control and robotics, not high-speed transient capture. |
| Output Impedance | 1400–3000 Ω; requires low-input-bias-current op-amp buffer or high-impedance ADC input to avoid loading-induced gain error. |
Pinout & Package
MPXM2102A uses the MPAK package (Case 1320), a 4-pin surface-mount housing with stainless steel cap and integrated pressure port. The package provides environmental isolation via silicone gel over the die while transmitting pressure to the silicon diaphragm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | GND | Ground reference for supply and output; must be low-impedance connection to minimize common-mode noise in single-supply systems. |
| Pin 2 | –VOUT | Negative output terminal; differential output pair (Pin 2 & Pin 4) delivers voltage proportional to pressure, referenced to GND. |
| Pin 3 | VS | Positive supply input (10 VDC typical); ratiometric behavior means output scales linearly with VS, requiring stable regulation. |
| Pin 4 | +VOUT | Positive output terminal; forms differential pair with Pin 2; output voltage = VOFF + (0.4 mV/kPa × P) × (VS/10), where VOFF = –2.0 to +2.0 mV. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Reduces system-level calibration effort by correcting span and offset drift over –40°C to +125°C, enabling single-point calibration at room temperature. |
| Laser-trimmed resistor network | Ensures factory-set accuracy of ±0.6%VFSS linearity and ±0.5%VFSS offset stability after 1000-hour stress testing. |
| Ratiometric output architecture | Eliminates need for precision voltage reference; output scales with supply rail, simplifying power design when using regulated 10 VDC sources. |
| Stainless steel cap with silicone gel isolation | Provides mechanical robustness and moisture resistance while maintaining pressure coupling integrity for long-term reliability in harsh environments. |
| Dry air–validated pressure media | Guarantees specified performance only with dry air; alternate media (e.g., gases, liquids) require factory validation to prevent drift or corrosion. |
Applications
| Barometric Pressure Monitoring | Altitude Estimation |
|---|---|
Use Scenario: Continuous atmospheric pressure logging in weather stations and portable environmental sensors. IC Role / Device Role / Timing Role: Absolute pressure transducer providing calibrated analog voltage output referenced to internal vacuum cavity.

IC Role / Device Role / Timing Role: System-level pressure feedback sensor interfacing with PID controller via buffered analog input. Use Value: 400 kPa maximum pressure rating allows safe operation during startup surges; ±0.1%VFSS hysteresis prevents oscillation in control loops. | Use Scenario: Non-invasive blood pressure and respiratory flow monitoring in portable diagnostic tools. IC Role / Device Role / Timing Role: Low-noise absolute pressure front-end for analog signal chain conditioning prior to digitization. Use Value: On-chip compensation eliminates need for thermistor-based correction, reducing BOM count and PCB area in space-constrained handheld units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX2102A | Unibody package (Case 344), 0–100 kPa, same core die but different封装 and port geometry; higher thermal mass, slower warm-up (20 ms). | Through-hole mounting; suited for prototyping and legacy designs with larger board real estate. | Select MPX2102A only if through-hole assembly or manual rework is required; MPXM2102A offers superior thermal response and SMT compatibility. |
| MPXV2102GP | Small outline package (Case 1369), gauge configuration (P1–P2), 0–100 kPa range; lacks internal vacuum reference, requires external venting. | Requires PCB-level atmospheric vent path; unsuitable for sealed-barometer use without hardware modification. | Choose MPXV2102GP only for differential or gauge applications with accessible ambient reference; not a functional substitute for MPXM2102A's absolute measurement capability. |
Compared with MPX2102A and MPXV2102GP, MPXM2102A uniquely combines absolute pressure measurement, MPAK SMT packaging, and optimized thermal response-making it the only drop-in solution for compact, sealed-altimeter designs requiring no external venting or through-hole footprint.

FAQ
What is the pressure type supported by the MPXM2102A?
The MPXM2102A is an absolute pressure sensor with an internal vacuum reference cavity. It measures pressure relative to absolute zero (vacuum), covering 0–100 kPa. This makes MPXM2102A suitable for barometric and altimeter applications where ambient atmospheric pressure is the measured quantity-not differential or gauge pressure.
Does the MPXM2102A require external temperature compensation?
No, the MPXM2102A includes on-chip temperature compensation circuitry calibrated over –40°C to +125°C. This eliminates the need for external thermistors or software-based correction algorithms. The MPXM2102A maintains ±0.6%VFSS linearity and controlled TcSpan (±2.0%VFSS) and TcOffset (±1.0 mV) across its full operating range, as verified in the Freescale MPX2102 Rev. 9 datasheet.
What is the correct pin configuration for MPXM2102A?
The MPXM2102A uses a 4-pin MPAK package (Case 1320) with the following pinout: Pin 1 = GND, Pin 2 = –VOUT, Pin 3 = VS (10 VDC), Pin 4 = +VOUT. This matches "Style 1" shown in the datasheet package drawings. Incorrect orientation or miswiring will result in inverted or absent output voltage.
Can the MPXM2102A be used with pressure media other than dry air?
The MPXM2102A is characterized and qualified exclusively with dry air as the pressure medium. Using other gases, vapors, or liquids may cause performance degradation, calibration shift, or long-term reliability issues due to chemical interaction with the silicone gel or silicon diaphragm. Contact NXP for media compatibility validation before deploying MPXM2102A with non-dry-air media.
What is the maximum overpressure rating for MPXM2102A?
The MPXM2102A has a maximum pressure rating of 400 kPa (58 psi), as specified in the Absolute Maximum Ratings table. Exceeding this limit-even momentarily-may cause permanent damage to the silicon diaphragm or bonding wires. For applications with potential pressure spikes, external mechanical overpressure protection (e.g., restrictor or relief valve) is recommended to ensure MPXM2102A longevity.
