Product details
Overview
MPXM2102AS from NXP Semiconductors (formerly Freescale) is a monolithic 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 range. It features ±0.6%VFSS linearity, ±0.1%VFSS pressure hysteresis, and operates from −40°C to +125°C. Used in medical diagnostics and barometric sensing where stable low-pressure measurement is required.
For engineers reviewing the MPXM2102AS datasheet, MPXM2102AS pinout, MPXM2102AS application, or MPXM2102AS equivalent, key selection criteria include its MPAK package (Case 1320A), differential/gauge-compatible port configuration, 1.0 ms response time, and compatibility with 10 VDC excitation for analog signal conditioning in embedded pressure monitoring systems.
Technical Context
The MPXM2102AS integrates a laser-trimmed silicon diaphragm with thin-film resistor networks for span and offset calibration. Its ratiometric output scales linearly with supply voltage, enabling direct interface with ADCs without external reference scaling.
On-chip temperature compensation corrects both full-scale span (TCVFSS ±2.0%VFSS) and offset (TCVOFF ±1.0 mV) over 0°C to +85°C, while maximum operating temperature extends to +125°C. The device uses dry air as specified pressure media and requires identification of the P1 (pressure) side per Case 1320A port-attached marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa absolute - defines full-scale input for medical barometry and altitude sensing |
| Full Scale Output | 40 mV typical at 10 V supply - enables high-resolution 12-bit+ ADC digitization with minimal gain |
| Linearity Error | ±0.6%VFSS (end-point method) - ensures <±0.6 kPa absolute error across full scale |
| Response Time | 1.0 ms (10%–90%) - supports dynamic pressure monitoring up to ~350 Hz bandwidth |
| Supply Voltage | 10 VDC nominal, 16 VDC max - compatible with standard industrial 10 V references and tolerant of rail variation |
| Operating Temp | −40°C to +125°C - validated for under-hood automotive and industrial ambient environments |
| Offset Voltage | −2.0 to +2.0 mV at min pressure - sets baseline for zero-pressure calibration in system firmware |
Pinout & Package
MPXM2102AS is housed in the MPAK package (Case 1320A), a surface-mount, 4-pin leaded ceramic package with stainless-steel port attachment and silicone-gel-isolated die. Pin 1 is ground, Pin 2 is −VOUT, Pin 3 is VS, and Pin 4 is +VOUT - matching Style 3 pinout per Freescale documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | GND | Reference ground for supply and output - must be low-impedance connection to minimize noise coupling |
| Pin 2 | −VOUT | Negative output terminal - forms differential pair with Pin 4; used for noise-rejecting instrumentation amp inputs |
| Pin 3 | VS | Positive supply input - supplies internal Wheatstone bridge; ratiometric output depends on stability of this rail |
| Pin 4 | +VOUT | Positive output terminal - delivers voltage proportional to applied pressure relative to vacuum reference |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Corrects span and offset errors over 0°C to +85°C without external circuitry |
| Laser-trimmed calibration | Eliminates need for system-level trimming; achieves ±0.6%VFSS linearity out-of-box |
| Ratiometric output | Output scales with supply voltage - removes dependency on precision voltage references |
| Differential output architecture | Enables common-mode noise rejection in noisy EMI environments via instrumentation amplifiers |
| MPAK package with port-attached P1 side | Facilitates PCB-level mounting with direct hose/barb connection to pressure source |
Applications
| Medical Diagnostics | Barometric Sensing |
|---|---|
Use Scenario: Non-invasive respiratory flow and airway pressure monitoring in portable ventilators and spirometers. IC Role / Device Role / Timing Role: Absolute pressure transducer measuring patient airway pressure relative to sealed vacuum reference. Use Value: Delivers ±0.1 kPa repeatability and <1 ms response - sufficient for real-time breath cycle detection and alarm triggering. |
Use Scenario: Altitude estimation and weather station pressure logging in battery-powered IoT nodes. IC Role / Device Role / Timing Role: High-stability absolute pressure sensor referenced to internal vacuum cavity. Use Value: −40°C to +85°C compensated operation ensures <±0.5 kPa drift over environmental cycling, critical for long-term calibration stability. |
| Pump/Motor Control | Level Detectors |
Use Scenario: Closed-loop pressure feedback in HVAC blower control and industrial pump systems. IC Role / Device Role / Timing Role: Absolute pressure monitor detecting system backpressure to modulate motor speed. Use Value: 100 kPa full-scale range and 6 mA supply current enable direct microcontroller interfacing with minimal external components. |
Use Scenario: Liquid level measurement in tanks using hydrostatic pressure of column height. IC Role / Device Role / Timing Role: Gauge-mode pressure sensor (P1 exposed to fluid, P2 vented to atmosphere). Use Value: Port-attached P1 side (Case 1320A) allows direct hose coupling to tank bottom port; ±0.1%VFSS hysteresis prevents false level transitions during fill/empty cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7002DP | Smaller SOIC-8 package; 0–25 kPa range; 2.5 V supply; I²C digital output | Requires microcontroller with I²C; unsuitable for analog-only systems or >25 kPa ranges | Select when digital interface and space constraints outweigh need for analog simplicity and extended range. |
| MP3V5050G | 50 kPa gauge range; 5 V supply; 0.5–4.5 V ratiometric output; same MPAK package | Lacks absolute vacuum reference; not usable for barometric or altimeter applications | Choose only for differential/gauge pressure tasks where vacuum reference is unnecessary and 5 V rails dominate the design. |
Compared with MPXM2102AS, MPXV7002DP offers digital convenience but sacrifices analog flexibility and full-scale range, while MP3V5050G shares the MPAK form factor but lacks the absolute reference needed for atmospheric pressure measurement - making MPXM2102AS uniquely suited for calibrated barometric and medical absolute pressure use cases.

FAQ
What is the pressure type supported by the MPXM2102AS?
The MPXM2102AS is an absolute pressure sensor with a built-in vacuum reference cavity. It measures pressure relative to absolute zero (vacuum), not ambient atmospheric pressure. This makes MPXM2102AS appropriate for barometric sensing, altimeters, and medical devices requiring true absolute pressure values independent of local weather conditions.
What is the correct pinout configuration for MPXM2102AS?
The MPXM2102AS uses Style 3 pinout per Freescale documentation: Pin 1 = GND, Pin 2 = −VOUT, Pin 3 = VS, Pin 4 = +VOUT. This differential output configuration requires connection to an instrumentation amplifier or differential-input ADC. The P1 (pressure) side is identified by the port-attached marking on the Case 1320A package.
Can MPXM2102AS operate with a 5 V supply instead of 10 V?
MPXM2102AS is specified for 10 VDC nominal supply (range 10–16 VDC). While it may produce output at 5 V, the full-scale output drops to ~20 mV and temperature compensation performance is not guaranteed outside the validated 10 V operating point. Using 5 V violates the datasheet's excitation specification and risks increased error beyond ±1.0%VFSS.
Is MPXM2102AS compatible with wet media such as water or oil?
No. MPXM2102AS is qualified only for dry air as the pressure medium. Exposure to liquids, oils, or corrosive gases may degrade the silicone gel isolation layer and damage the silicon diaphragm. For wet media, NXP recommends evaluating purpose-built media-isolated sensors like the MP3H6115A or contacting factory application engineering for compatibility testing.
What is the warm-up time specification for MPXM2102AS?
The MPXM2102AS has a specified warm-up time of 20 ms - defined as the time required after power-on for output to settle within final value tolerance. This allows rapid system initialization in battery-powered devices. Full thermal stabilization for temperature-compensated accuracy occurs within seconds, but electrical output is stable within 20 ms for timing-critical sampling.
