Product details
Overview
MPXM2102GST1 from NXP Semiconductors (formerly Freescale) is a gauge-mode silicon piezoresistive pressure sensor with on-chip temperature compensation, delivering 40 mV full-scale output at 10 V supply over a 0–100 kPa range, used for precise fluid pressure monitoring in medical diagnostics and industrial level detection.
For engineers reviewing the MPXM2102GST1 datasheet, MPXM2102GST1 pinout, MPXM2102GST1 application, or MPXM2102GST1 equivalent, this page provides verified technical context, calibrated performance parameters, MPAK package details, real-world use cases, and validated alternative options for pressure sensing design-in.
Technical Context
The MPXM2102GST1 implements a monolithic silicon diaphragm with integrated strain gauges and thin-film resistor networks laser-trimmed for span and offset calibration. Its ratiometric output scales linearly with applied differential pressure (P1 > P2) and maintains stability across -40°C to +125°C operating temperature.
It features built-in temperature compensation for both full-scale span (±2.0 %VFSS TC) and offset (±1.0 mV TC), with <1.0 ms response time and ±0.1 %VFSS pressure hysteresis - enabling direct analog interfacing without external signal conditioning in low-power embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa gauge (0–14.5 psi); defines measurable differential pressure with P1 side exposed to process media and P2 referenced to ambient. |
| Full Scale Output | 40 mV typical at 10 V supply; enables high-resolution ADC sampling with minimal gain stages in 3.3 V or 5 V microcontroller systems. |
| Supply Voltage | 10 VDC nominal (6–16 VDC range); ratiometric operation ensures output scaling remains proportional to excitation voltage changes. |
| Supply Current | 6.0 mA typical; supports continuous operation in battery-powered portable devices with predictable power budgeting. |
| Linearity Error | ±0.4 %VFSS (end-point method); guarantees measurement accuracy within ±0.4 kPa across full scale without software correction. |
| Response Time | 1.0 ms (10%–90%); suitable for dynamic pressure events such as pump cycling or valve actuation monitoring. |
| Operating Temp | -40°C to +125°C; validated for under-hood automotive, industrial HVAC, and medical equipment environments. |
Pinout & Package
MPXM2102GST1 uses the MPAK package (Case 1320A), a surface-mount, 4-pin ceramic leadframe package with stainless steel port attachment on the P1 side and molded silicone gel isolation for environmental protection.
| 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 analog signal chain. |
| Pin 2 | −VOUT | Negative output terminal; forms differential pair with Pin 4; required for noise-rejecting instrumentation amplifier interfaces. |
| Pin 3 | VS | Positive supply input (6–16 VDC); supplies bias current to internal Wheatstone bridge and compensation circuitry. |
| Pin 4 | +VOUT | Positive output terminal; delivers voltage proportional to pressure (e.g., 0–40 mV at 10 V supply); referenced to Pin 1 ground. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Calibrated over 0°C to +85°C; eliminates need for external thermistor or digital compensation algorithms in cost-sensitive designs. |
| Gauge configuration with P1/P2 port identification | P1 side marked by port attachment (per Case 1320A mechanical drawing); ensures correct orientation during PCB assembly for repeatable pressure interface. |
| Laser-trimmed span and offset | Factory-set to ±1.0 mV offset and ±0.4 %VFSS linearity; reduces post-manufacturing calibration effort in production test. |
| Differential output architecture | Delivers balanced +VOUT/−VOUT signals; improves common-mode rejection ratio (CMRR) when paired with INA12x or similar instrumentation amplifiers. |
| MPAK surface-mount package | Compatible with standard reflow profiles; enables automated assembly and compact board layout in space-constrained medical or robotics modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7002DP | 5 V ratiometric supply, 0.25–2.25 V output, SOIC-8 package, 0–100 kPa range. | Requires single-ended interface and external voltage regulation; lacks differential output. | Choose when board space allows SOIC-8 and system uses 5 V rails with no need for noise-immune differential signaling. |
| MP3V5050G | 3.3 V supply, 0.1–4.9 V output, 0–50 kPa range, integrated signal conditioning, SOP-8 package. | Includes internal amplifier and regulator; narrower pressure range and higher quiescent current (≈1.5 mA). | Choose when simplified analog interface and lower supply voltage are prioritized over full 100 kPa range and ultra-low offset drift. |
Compared with MPXM2102GST1, MPXV7002DP offers easier 5 V integration but sacrifices differential noise rejection, while MP3V5050G reduces external component count at the expense of pressure range and long-term offset stability - making MPXM2102GST1 optimal for high-accuracy, low-drift, industrial-grade gauge sensing.

FAQ
What is the pressure type supported by MPXM2102GST1?
The MPXM2102GST1 is a gauge pressure sensor: it measures differential pressure between its P1 (process side, marked by port attachment) and ambient-referenced P2 side. It is not an absolute or differential sensor - its output increases with increasing pressure applied to P1 relative to atmospheric pressure at P2. This configuration is confirmed in Freescale's ordering table and mechanical drawings for Case 1320A.
Does MPXM2102GST1 require external signal conditioning?
No, MPXM2102GST1 does not require external signal conditioning for basic operation: its 40 mV full-scale output is directly compatible with 16-bit+ ADCs in microcontrollers like STM32 or PIC32. However, its differential output (+VOUT/−VOUT) is optimized for use with instrumentation amplifiers (e.g., INA128) to reject common-mode noise - making external gain/level-shifting optional but recommended for noisy environments.
What is the maximum pressure rating for MPXM2102GST1?
The MPXM2102GST1 has a maximum pressure rating of 400 kPa (58 psi), as specified in the Maximum Ratings table of the official datasheet. This burst pressure rating applies across the full operating temperature range (−40°C to +125°C) and represents the upper limit before mechanical damage may occur - well above its 0–100 kPa operating range.
How is temperature compensation implemented in MPXM2102GST1?
MPXM2102GST1 implements on-chip temperature compensation using laser-trimmed thin-film resistors integrated into the Wheatstone bridge and compensation network. This achieves ±2.0 %VFSS full-scale span drift and ±1.0 mV offset drift over −40°C to +125°C, eliminating the need for external thermistors or digital correction algorithms in most applications.
Can MPXM2102GST1 be used in humid or corrosive environments?
MPXM2102GST1 incorporates silicone gel encapsulation over the die and wire bonds (per Figure 3 cross-section), providing moisture resistance and mechanical protection. However, Freescale explicitly states that operating characteristics and reliability testing were performed using dry air - contact NXP for compatibility data before deploying in aggressive media such as saline, solvents, or high-humidity condensing environments.
