Product details
Overview
MPXM2102AST1 from NXP Semiconductors (formerly Freescale) is a silicon piezoresistive absolute pressure sensor with on-chip temperature compensation, delivering 40 mV full-scale output at 10 V supply across 0–100 kPa range, ±0.6%VFSS linearity, and operation from –40°C to +125°C - used in medical diagnostics, barometric sensing, and pump control systems.
For engineers reviewing the MPXM2102AST1 datasheet, MPXM2102AST1 pinout, MPXM2102AST1 application, or MPXM2102AST1 equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for industrial and embedded pressure-sensing designs.
Technical Context
The MPXM2102AST1 integrates a monolithic silicon diaphragm with laser-trimmed strain gauges and thin-film resistor networks for precision span and offset calibration. Its ratiometric output scales linearly with supply voltage and applied pressure, enabling direct interfacing with ADCs without external signal conditioning.
It features on-chip temperature compensation over 0°C to +85°C, with TcSpan ≤ ±2.0%VFSS and TcOffset ≤ ±1.0 mV across –40°C to +125°C operating range. The device uses dry air as specified pressure media and requires identification of P1 (pressure) and P2 (vacuum/reference) sides per mechanical marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa absolute - matches standard atmospheric pressure range for barometric and altitude-sensing applications. |
| Full Scale Output | 40 mV typical at 10 V supply - enables high-resolution analog-to-digital conversion with minimal gain staging. |
| Linearity Error | ±0.6%VFSS (end-point method) - supports accurate pressure measurement without software linearization in many embedded systems. |
| Supply Voltage | 10 VDC nominal, 16 VDC max - compatible with standard industrial 10–12 V rails; ratiometric behavior simplifies system-level calibration. |
| Response Time | 1.0 ms (10%–90%) - suitable for dynamic pressure monitoring in motor control and robotics feedback loops. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial HVAC, and portable medical equipment environments. |
| Offset Voltage | –2.0 to +2.0 mV at minimum pressure - low initial offset reduces zero-adjustment burden in production calibration. |
Pinout & Package
MPXM2102AST1 uses the MPAK package (Case 1320A), a surface-mount, 4-pin, stainless-steel-capped housing with port-attached side identification. Dimensions: 29.08 × 17.40 × 8.26 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | GND | Ground reference for both supply and output; must be low-impedance to minimize noise coupling into sensitive analog output. |
| Pin 2 | –VOUT | Negative output terminal; differential output pair (Pin 2 & Pin 4) delivers pressure-proportional voltage with common-mode rejection capability. |
| Pin 3 | VS | Positive supply input; ratiometric output means output scale tracks supply variations - critical for unregulated power sources. |
| Pin 4 | +VOUT | Positive output terminal; output voltage increases linearly with applied absolute pressure relative to internal vacuum reference. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over 0°C to +85°C - eliminates need for external thermistor networks or digital compensation algorithms in most applications. |
| Laser-trimmed calibration | Factory-set span and offset - reduces BOM count and assembly time by removing manual potentiometer adjustments. |
| Differential analog output | 40 mV full-scale swing with matched impedance - improves noise immunity and enables direct connection to instrumentation amplifiers or differential ADC inputs. |
| Stainless steel cap & silicone gel isolation | Robust environmental sealing per Case 1320A - protects die and wire bonds while transmitting pressure signal reliably in humid or particulate-laden environments. |
| MPAK surface-mount package | Tape-and-reel delivery (AST1 suffix) - optimized for automated pick-and-place assembly in high-volume industrial and medical OEM production. |
Applications
| Medical Diagnostics | Barometric Sensing |
|---|---|

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 | 2.5 V ratiometric output, 0–100 kPa, SOIC-8 package, integrated signal conditioning - higher integration but lower output swing (25 mV). | Requires no external amplifier; better suited for low-voltage (3.3 V) systems but less SNR headroom than MPXM2102AST1's 40 mV. | Select when board space is constrained and supply is ≤3.3 V; avoid if legacy 10 V analog rails or high-precision ADCs are used. |
| MPX5700AP | 0–700 kPa range, 5 V supply, 0.2–4.8 V output, Case 422B - wider pressure range, single-ended output, higher supply current (7 mA). | Designed for high-pressure industrial hydraulics; incompatible with 100 kPa barometric or medical use due to range mismatch and non-ratiometric scaling. | Use only when pressure exceeds 100 kPa; not a functional substitute for MPXM2102AST1 in low-range applications. |
Compared with MPXM2102AST1, MPXV7002DP offers smaller footprint and lower supply voltage compatibility but sacrifices output amplitude and thermal stability margin, while MPX5700AP trades precision and low-range linearity for extended pressure coverage - neither is pin-compatible, and both require PCB layout and firmware adaptation.

FAQ
What is the pressure type and range supported by MPXM2102AST1?
The MPXM2102AST1 is an absolute pressure sensor with a rated range of 0–100 kPa (0–14.5 psi). It contains an internal vacuum reference, so its output reflects absolute atmospheric or sealed-system pressure relative to vacuum - not differential or gauge pressure. This makes MPXM2102AST1 appropriate for barometric, altimeter, and medical diagnostic applications where ambient pressure tracking is required.
Does MPXM2102AST1 require external temperature compensation?
No, MPXM2102AST1 includes on-chip temperature compensation circuitry calibrated over 0°C to +85°C. Its full-scale span drift is limited to ±2.0%VFSS and offset drift to ±1.0 mV across –40°C to +125°C, eliminating the need for external thermistors or digital compensation algorithms in most implementations. This built-in compensation is factory-laser-trimmed and verified per Freescale's Rev. 9 datasheet.
What is the correct pin configuration and orientation for MPXM2102AST1?
MPXM2102AST1 follows Style 1 pinout in Case 1320A: Pin 1 = GND, Pin 2 = –VOUT, Pin 3 = VS, Pin 4 = +VOUT. The pressure port is located on the side marked with part number and "P1" designation - this is the positive pressure side. The opposite side (stainless steel cap) is the reference (vacuum) side. Mounting orientation must ensure unobstructed access to the P1 port for accurate pressure coupling.
Can MPXM2102AST1 be used with a 3.3 V supply?
No - MPXM2102AST1 is specified for 10 VDC nominal supply (range 10–16 VDC). Operating below 10 V results in reduced output swing, degraded linearity, and potential instability per Freescale's datasheet Table 1. For 3.3 V systems, consider alternatives like MPXV7002DP or MPX5050GP, which are explicitly characterized for low-voltage operation. Using MPXM2102AST1 at 3.3 V violates its electrical specifications and voids performance guarantees.
Is MPXM2102AST1 RoHS compliant and halogen-free?
Yes - MPXM2102AST1 conforms to RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The MPAK package (Case 1320A) uses lead-free solderable terminations and environmentally compliant molding compounds. Full compliance documentation, including material declarations and test reports, is available through NXP's official product page and authorized distributor portals.
