Product details
Overview
MPXV2102DP from Freescale Semiconductor is a differential silicon piezoresistive pressure sensor with on-chip temperature compensation, delivering 40 mV full-scale output at 10 V supply across a 0–100 kPa differential pressure range, used in precision pump control and medical diagnostics systems.
For engineers reviewing the MPXV2102DP datasheet, MPXV2102DP pinout, MPXV2102DP application, or MPXV2102DP equivalent, this page provides verified technical context, calibrated performance specs, package-validated pin functions, real-world use cases, and two confirmed alternative parts for differential pressure sensing in industrial and medical embedded designs.
Technical Context
The MPXV2102DP implements a monolithic silicon diaphragm with integrated strain gauge and thin-film resistor network, laser-trimmed for span and offset calibration. Its ratiometric output scales linearly with applied differential pressure (P1 > P2) and maintains stability over −40°C to +125°C operating temperature.
It features on-chip temperature compensation for both full-scale span (±2.0 %VFSS TCVFSS) and offset (±1.0 mV TCVOFF), with <1.0 ms response time and ±0.1 %VFSS pressure hysteresis - optimized for dry air media in sealed or vented differential configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa differential (P1 > P2); supports precise low-pressure monitoring without vacuum reference |
| Full Scale Output | 40 mV typical at 10 V supply; enables direct ADC interfacing with minimal signal conditioning |
| Supply Voltage | 10 VDC nominal (6–16 VDC range); ratiometric operation ensures output scaling with supply variation |
| Linearity Error | ±0.4 %VFSS (end-point method); guarantees predictable voltage-to-pressure mapping across full scale |
| Temperature Range | −40°C to +125°C operating; validated for harsh environments including motor enclosures and portable medical devices |
| Response Time | 1.0 ms (10%–90%); suitable for dynamic pressure events such as pump cycling or respiratory flow detection |
| Offset Voltage | ±1.0 mV at minimum pressure; tight offset enables high-resolution zero-pressure detection |
Pinout & Package
MPXV2102DP uses the Unibody Package (Case 344C), a stainless-steel-capped, dual-port ceramic package with silicone gel isolation of the die surface. 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; must be low-impedance connection to minimize common-mode error |
| Pin 2 | + OUTPUT | Positive differential output terminal; voltage increases with rising P1–P2 pressure difference |
| Pin 3 | + SUPPLY | Excitation input (6–16 VDC); powers internal Wheatstone bridge and compensation circuitry |
| Pin 4 | − OUTPUT | Negative differential output terminal; completes differential pair for noise-rejecting measurement |
Key Features
| Feature | Design Value |
|---|---|
| Differential pressure configuration | Two isolated ports (P1/P2) enable true differential sensing without external reference, eliminating ambient drift |
| On-chip temperature compensation | Calibrated over 0°C to +85°C; reduces system-level temperature correction firmware overhead |
| Laser-trimmed span and offset | Factory-set accuracy eliminates need for end-of-line trimming in production test |
| Ratiometric output | Output scales with supply voltage; allows shared reference between sensor and ADC for improved ratio-metric accuracy |
| Low hysteresis | ±0.1 %VFSS pressure hysteresis ensures repeatable readings during cyclic pressure applications like valve actuation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX2102DP | Same core die, Case 344C unibody package, 0–100 kPa differential, 40 mV FS | Identical functional specification; legacy Freescale part with same pinout and calibration | Select when sourcing original-design hardware requiring exact form-fit-function match and long-term availability assurance |
| MPXM2102D | MPAK package (Case 1320), same 0–100 kPa range and 40 mV FS, but higher input impedance (1000–2500 Ω) | Surface-mount compatible; better suited for space-constrained PCBs where through-hole Case 344C is impractical | Choose for new designs prioritizing automated assembly and smaller footprint, accepting minor packaging and thermal mass differences |
Compared with MPXV2102DP, MPX2102DP offers identical electrical performance and pin compatibility but differs only in date code and documentation revision; MPXM2102D provides equivalent sensing capability in a compact MPAK package ideal for high-density layouts, though with distinct mechanical mounting and thermal response.

FAQ
What is the pressure type and range supported by the MPXV2102DP?
The MPXV2102DP is a differential pressure sensor with a specified range of 0–100 kPa (0–14.5 psi). It requires two independent pressure ports (P1 and P2), and its output voltage increases proportionally when pressure on P1 exceeds pressure on P2. This configuration eliminates dependence on ambient atmospheric reference and supports sealed-system monitoring.
Does the MPXV2102DP require external temperature compensation?
No, the MPXV2102DP includes on-chip temperature compensation for both full-scale span and offset across 0°C to +85°C. The device is laser-trimmed during manufacturing to maintain ±0.4 %VFSS linearity and ±2.0 %VFSS TCVFSS, eliminating the need for external thermistors or software-based correction in most applications.
What is the supply voltage requirement and current draw for the MPXV2102DP?
The MPXV2102DP operates from 6 VDC to 16 VDC, with 10 VDC as the nominal excitation voltage. At 10 VDC, it draws 6.0 mA typical supply current. Its ratiometric output ensures that output voltage scales linearly with supply voltage, simplifying system-level calibration when paired with a matching ADC reference.
How is the MPXV2102DP pinout configured, and what is the function of Pin 4?
The MPXV2102DP uses a 4-pin unibody package (Case 344C) with Pin 1 = GROUND, Pin 2 = +OUTPUT, Pin 3 = +SUPPLY, and Pin 4 = −OUTPUT. Pin 4 forms the negative leg of the differential output pair, enabling noise-rejecting measurements when used with instrumentation amplifiers or differential ADC inputs.
Can the MPXV2102DP be used with media other than dry air?
Freescale specifies MPXV2102DP performance and reliability based on dry air as the pressure medium. Exposure to moisture, oils, or corrosive gases may degrade long-term stability or damage the silicone-gel-isolated die. For non-dry-air applications, consult NXP's media compatibility documentation or contact factory support before deployment.
