Product details
Overview
MPXM2102AT1 from NXP Semiconductors (formerly Freescale) is a temperature-compensated silicon piezoresistive pressure sensor in MPAK package, providing 40 mV full-scale output at 10 V supply, ±0.6% VFSS linearity over 0–100 kPa absolute pressure range, and operating from –40°C to +125°C. It serves as a primary analog pressure transducer in medical diagnostics, barometric sensing, and industrial pump control systems.
For engineers reviewing the MPXM2102AT1 datasheet, MPXM2102AT1 pinout, MPXM2102AT1 application, or MPXM2102AT1 equivalent, key selection criteria include its ratiometric 10 V excitation requirement, on-chip temperature compensation across 0–85°C, 1 ms response time, and stainless-steel cap-based absolute pressure configuration with P1-side identification.
Technical Context
The MPXM2102AT1 integrates a monolithic silicon diaphragm with laser-trimmed piezoresistive strain gauges and thin-film resistor networks for precision span and offset calibration. Its internal circuitry includes on-chip temperature compensation circuitry that actively corrects both full-scale span drift (±2.0% VFSS/°C) and offset drift (±1.0 mV/°C) over 0–85°C.
This absolute-pressure sensor features a built-in reference vacuum cavity, delivering a decreasing output voltage under vacuum applied to the P1 side. It operates ratiometrically - output scales linearly with supply voltage - and requires no external signal conditioning beyond basic buffering due to its low-impedance differential output (ZOUT = 1400–3000 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa absolute; defines full-scale input range for calibrated output, compatible with 14.5 psi applications. |
| Full Scale Span | 38.5–41.5 mV at VS = 10 VDC; enables direct ADC interfacing with ≥12-bit resolution for sub-1 kPa accuracy. |
| Supply Voltage | 10 VDC typical, 16 VDC max; ratiometric operation ensures output scaling with supply, simplifying system-level calibration. |
| Linearity Error | ±0.6% VFSS (end-point method); specifies worst-case deviation from ideal linear transfer function over full pressure range. |
| Response Time | 1.0 ms (10%–90%); supports dynamic pressure monitoring in fast-cycling pneumatic systems and motor control loops. |
| Operating Temp | –40°C to +125°C ambient; validated for harsh environments including engine bay and industrial enclosures. |
| Offset Voltage | –2.0 to +2.0 mV at min pressure; sets baseline output level, critical for zero-pressure reference in altimeter/barometer designs. |
Pinout & Package
MPXM2102AT1 uses the MPAK package (Case 1320), featuring a stainless-steel cap on the P1 (pressure) side and a molded plastic body with 4-pin lead frame. The package provides environmental isolation via silicone gel encapsulation of the die and wire bonds.
| 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 differential measurement. |
| Pin 2 | +VOUT | Positive output terminal; delivers voltage proportional to applied absolute pressure relative to internal vacuum reference. |
| Pin 3 | VS | Supply input (10 VDC typical); powers internal Wheatstone bridge and compensation circuitry; ratiometric behavior ties output scaling directly to this rail. |
| Pin 4 | –VOUT | Negative output terminal; completes differential output pair; enables rejection of common-mode supply and thermal noise. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over 0°C to +85°C ambient; eliminates need for external thermistor networks or digital correction in embedded systems. |
| Laser-trimmed calibration | Factory-set span and offset; achieves ±0.6% VFSS linearity without user trimming, reducing production test time. |
| Differential output architecture | Low-impedance balanced pair (ZOUT = 1400–3000 Ω); improves noise immunity and enables direct connection to instrumentation amplifiers or SAR ADCs. |
| Stainless-steel absolute pressure port | P1-side metal cap with defined port geometry; ensures long-term stability and compatibility with dry air, non-corrosive gases, and medical-grade media. |
| Ratiometric output | Output scales linearly with VS; allows use of same supply for sensor and ADC reference, removing gain error from supply variation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure transducer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5100AP | Wider 0–100 kPa range but higher 50 mV FS output; requires 5 V supply; different M12 package with dual ports. | Designed for gauge/differential configurations; lacks stainless-steel absolute cap; unsuitable for vacuum-referenced barometry. | Select MPX5100AP only when 5 V system integration and higher output SNR outweigh package and reference differences. |
| MPXV7002DP | 2.5 V supply, I²C digital output, ±1.5% accuracy; smaller SMD package; no analog differential output. | Targets low-power, digitally interfaced designs; lacks analog ratiometric output needed for legacy ADC or analog control loops. | Choose MPXV7002DP for new battery-powered designs requiring digital bus integration and minimal external components. |
Compared with MPXM2102AT1, MPX5100AP offers higher output but requires redesign for 5 V biasing and lacks absolute vacuum reference integrity, while MPXV7002DP trades analog flexibility for digital convenience and reduced accuracy - making MPXM2102AT1 optimal for analog-critical, temperature-stable absolute pressure measurement.

FAQ
What is the pressure type and reference configuration of the MPXM2102AT1?
The MPXM2102AT1 is an absolute pressure sensor with an internal vacuum reference cavity. Its output voltage decreases when vacuum is applied to the P1 (stainless-steel cap) side relative to ambient. This configuration makes MPXM2102AT1 suitable for barometric and altimetric applications where measurement is referenced to perfect vacuum, not ambient or another port.
Does the MPXM2102AT1 require external temperature compensation?
No, the MPXM2102AT1 includes on-chip temperature compensation circuitry validated over 0°C to +85°C. It corrects both full-scale span drift (TCVFSS = ±2.0% VFSS) and offset drift (TCVOFF = ±1.0 mV) without external components. This eliminates the need for thermistors or lookup-table firmware correction in most embedded applications using MPXM2102AT1.
What is the recommended supply voltage and current draw for MPXM2102AT1?
The MPXM2102AT1 is specified for 10 VDC typical supply (range: 10–16 VDC) and draws 6.0 mA typical supply current. Its ratiometric output means the full-scale voltage scales linearly with VS, so maintaining stable 10 V excitation ensures consistent 40 mV FS output. Operating above 16 VDC risks self-heating-induced errors and is not recommended for MPXM2102AT1.
How is the pinout oriented and how do I identify the P1 pressure side on MPXM2102AT1?
MPXM2102AT1 follows Style 1 pinout: Pin 1 = GND, Pin 2 = +VOUT, Pin 3 = VS, Pin 4 = –VOUT. The P1 (pressure) side is identified by the stainless-steel cap - confirmed in the datasheet for Case 1320 variants like MPXM2102AT1. Always mount the stainless-steel cap toward the measured pressure source when integrating MPXM2102AT1 into a system.
Can MPXM2102AT1 be used with dry air only, or is it compatible with other media?
The MPXM2102AT1's operating characteristics and reliability testing were performed using dry air. While the stainless-steel cap and silicone-gel isolation provide robustness, exposure to corrosive, condensing, or liquid media may degrade long-term performance. For non-dry-air applications, consult NXP's media compatibility documentation before deploying MPXM2102AT1 in final designs.
