Product details
Overview
MPX2102GVP from Freescale Semiconductor is a gauge-pressure silicon piezoresistive sensor with on-chip temperature compensation, 0–100 kPa pressure range, 40 mV full-scale output (typical), and ±0.4%VFSS linearity over 0°C to +85°C. It delivers ratiometric voltage output directly proportional to applied differential pressure and is used in industrial pump control, medical diagnostics, and level detection systems.
For engineers reviewing the MPX2102GVP datasheet, MPX2102GVP pinout, MPX2102GVP application, or MPX2102GVP equivalent, this page provides verified technical context, package mapping, calibrated performance parameters, and real-world use-case implementation guidance for embedded pressure sensing designs.
Technical Context
The MPX2102GVP integrates a monolithic silicon diaphragm with laser-trimmed strain gauges and thin-film resistor networks for precision span and offset calibration. Its on-chip temperature compensation circuitry actively corrects full-scale span drift (±2.0%VFSS) and offset drift (±1.0 mV) across –40°C to +125°C operating range.
This gauge configuration features two ports: P1 (positive pressure side, identified by stainless steel cap per Case 344D) and P2 (vacuum reference side). The ratiometric output (VS = 10 VDC) yields 0.4 mV/kPa sensitivity with 1.0 ms response time and <±0.1%VFSS pressure hysteresis over 0–100 kPa.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa gauge - supports industrial and medical applications requiring precise low-range differential pressure measurement relative to ambient. |
| Full Scale Output | 40 mV typical at 10 V supply - enables direct ADC interfacing without amplification in many 12-bit+ systems. |
| Linearity Error | ±0.4%VFSS (end-point method) - ensures high accuracy across full scale without software linearization in cost-sensitive designs. |
| Temperature Compensation | 0°C to +85°C - guarantees stable offset and span performance in uncontrolled environments like HVAC or portable diagnostics. |
| Response Time | 1.0 ms (10% to 90%) - suitable for dynamic pressure monitoring in motor control and robotics feedback loops. |
| Supply Voltage | 10 VDC nominal (6–16 VDC range) - ratiometric operation maintains accuracy despite supply rail variation in battery-powered systems. |
| Output Impedance | 1400–3000 Ω - compatible with standard instrumentation amplifier inputs without buffer stage in most signal chains. |
Pinout & Package
MPX2102GVP uses Unibody Package Case 344D: 4-pin, stainless steel cap, dual-port gauge configuration with P1 (pressure) and P2 (vacuum reference) ports. Dimensions: 29.08–29.85 mm × 17.40–18.16 mm × 7.75–8.26 mm (L×W×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground | Reference node for output and supply return; must be low-impedance path to minimize common-mode error. |
| Pin 2 | + Output (VOUT+) | High-side analog output terminal; voltage increases with rising P1 pressure relative to P2 vacuum reference. |
| Pin 3 | + Supply (VS) | Excitation input; ratiometric output scales linearly with this voltage - critical for supply rejection in noisy environments. |
| Pin 4 | – Output (VOUT–) | Differential output complement; used with Pin 2 for noise-rejecting instrumentation amplifier interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Reduces system-level calibration burden by correcting span and offset drift across –40°C to +125°C without external circuitry. |
| Laser-trimmed resistor network | Enables factory-calibrated 40 mV full-scale output and <±1.0 mV offset at 25°C, eliminating manual trimming in production. |
| Gauge pressure configuration | Provides absolute pressure measurement relative to ambient via integrated vacuum reference (P2 port), simplifying mechanical mounting vs. absolute sensors. |
| Stainless steel cap and silicone gel isolation | Protects die and wire bonds from moisture, particulates, and chemical exposure while transmitting pressure signal reliably in harsh environments. |
| Ratiometric output architecture | Ensures measurement accuracy remains stable even with ±10% supply variation - ideal for systems with unregulated or battery-derived rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV2102GP | Small Outline Package (Case 1369), same 0–100 kPa range and 40 mV output, but lower supply current (3.5 mA vs. 6.0 mA) and different pinout (3-pin SMT). | Preferred for space-constrained PCBs where through-hole Unibody mounting is impractical; lacks dual-port mechanical flexibility of MPX2102GVP. | Select MPXV2102GP when board area is critical and vacuum-reference port integration is handled externally. |
| MPXM2102GS | MPAK package (Case 1320A), identical gauge configuration and specs, but rated for higher burst pressure (600 kPa vs. 400 kPa) and wider operating temp (–40°C to +125°C). | Better suited for automotive under-hood or industrial washdown environments where mechanical robustness and extended temperature tolerance are required. | Choose MPXM2102GS when long-term reliability under thermal cycling or mechanical stress exceeds MPX2102GVP's qualification limits. |
Compared with MPXV2102GP and MPXM2102GS, the MPX2102GVP offers optimal balance of mechanical port accessibility, proven field reliability in medical/industrial enclosures, and compatibility with legacy Case 344D mounting fixtures - making it preferred for retrofit and medium-volume OEM deployments.

FAQ
What is the pressure type and reference configuration of the MPX2102GVP?
The MPX2102GVP is a gauge pressure sensor with a built-in vacuum reference on the P2 port. Its stainless steel cap identifies the P1 (positive pressure) side, and it measures differential pressure between ambient (P2) and applied pressure (P1), delivering output voltage proportional to that difference. This configuration makes MPX2102GVP ideal for applications requiring measurement relative to atmospheric pressure without external vacuum sources.
What is the recommended supply voltage and how does it affect MPX2102GVP output?
The MPX2102GVP operates with a nominal 10 VDC supply (range: 6–16 VDC) and features ratiometric output - meaning its 40 mV full-scale voltage scales linearly with supply voltage. At 10 V, output is 40 mV; at 12 V, it becomes ~48 mV. This behavior ensures measurement accuracy remains stable despite supply rail variation, a key advantage in battery-powered or unregulated systems using the MPX2102GVP.
How is temperature compensation implemented in the MPX2102GVP?
The MPX2102GVP incorporates on-chip temperature compensation circuitry that actively corrects both full-scale span drift (TCVFSS ≤ ±2.0%VFSS) and offset drift (TCVOFF ≤ ±1.0 mV) across –40°C to +125°C. This compensation is factory-laser-trimmed and requires no external components, enabling accurate pressure readings in environments with wide ambient fluctuations - a core design feature of the MPX2102GVP.
What are the mechanical mounting considerations for MPX2102GVP?
The MPX2102GVP uses Case 344D Unibody packaging with dual ports: P1 (identified by stainless steel cap) accepts positive pressure, while P2 (opposite side) serves as the vacuum reference. Mounting requires secure sealing of both ports using O-rings or gaskets compatible with dry air media; Freescale specifies performance validation only for dry air, so alternative media require factory consultation before deploying MPX2102GVP.
Can MPX2102GVP be used in safety-critical medical applications?
No - Freescale explicitly states the MPX2102GVP is not designed, intended, or authorized for use in systems supporting or sustaining life, including surgical implants or critical therapeutic devices. While widely deployed in diagnostic tools like spirometers, MPX2102GVP must undergo full system-level validation per IEC 62304 and ISO 13485 if integrated into Class II/III medical equipment, and its use remains at the customer's sole risk per Freescale's disclaimer.
