Product details
Overview
MPX2050DP from Freescale Semiconductor is a differential silicon piezoresistive pressure sensor with on-chip temperature compensation and laser-trimmed calibration, delivering 40 mV full-scale output at 10 V supply, ±0.25% linearity over 0–50 kPa range, and operation from −40°C to +125°C. It serves as a primary transduction element in medical diagnostics, pump control, and robotics for precise differential pressure measurement.
For engineers reviewing the MPX2050DP datasheet, MPX2050DP pinout, MPX2050DP application, or MPX2050DP equivalent, this page provides verified package mapping (Case 344C-01), confirmed ratiometric output behavior, validated dual-port differential configuration, and real-world design meaning of key specs including TCOffset, pressure hysteresis, and warm-up time.
Technical Context
The MPX2050DP integrates a monolithic silicon diaphragm with embedded strain gauge and thin-film resistor network, enabling direct voltage output proportional to differential pressure (P1 > P2). Its internal circuitry includes dedicated on-chip temperature compensation and calibration circuitry that corrects both span and offset across 0°C to +85°C.
It operates ratiometrically - output voltage scales linearly with supply voltage - and features a unique silicon shear-stress strain gauge architecture that improves stability under mechanical stress. The device uses dry air as the specified pressure medium; performance with other media requires factory validation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 50 kPa (0 to 7.25 psi) - defines usable differential input range before nonlinear saturation or damage risk. |
| Full Scale Span | 40 mV typical at 10 V supply - sets analog output scaling for ADC interface design and gain stage selection. |
| Linearity Error | ±0.25% VFSS (end-point method) - determines maximum deviation from ideal transfer curve in closed-loop control accuracy budgets. |
| Supply Voltage | 10 V typical, up to 16 V max - higher excitation increases signal amplitude but risks self-heating-induced drift beyond 10 V. |
| Response Time | 1.0 ms (10% to 90%) - enables use in dynamic systems like motor-driven pumps where pressure transients occur faster than 1 kHz. |
| Temperature Effect on Offset | ±1.0 mV over −40°C to +125°C - constrains zero-point drift in uncalibrated industrial environments without software compensation. |
| Input Impedance | 1000–2500 Ω - informs minimum drive capability required from supply regulator or buffer stage. |
Pinout & Package
MPX2050DP is housed in a unibody chip carrier package (Case 344C-01), featuring stainless steel port housing, silicone gel isolation, and epoxy-sealed lead frame. The package includes two pressure ports: P1 (pressure side, identified by part marking) and P2 (vacuum side).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Reference ground for output and supply return; must be low-impedance to avoid common-mode error in differential readout. |
| 2 | +VOUT | Positive output terminal; delivers voltage proportional to (P1 − P2); used with −VOUT for true differential acquisition. |
| 3 | VS | Supply input; ratiometric operation means output scale tracks VS variations - critical for unregulated supply designs. |
| 4 | −VOUT | Negative output terminal; completes differential pair; enables rejection of common-mode noise in instrumentation amplifiers. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-port differential configuration | Enables true differential pressure measurement (P1 vs P2), eliminating reliance on ambient reference and supporting vacuum-side sensing. |
| On-chip temperature compensation | Reduces span and offset drift over −40°C to +125°C without external circuitry - lowers BOM count in medical or automotive modules. |
| Laser-trimmed calibration | Delivers factory-set 40 mV FS span and near-zero offset, minimizing post-assembly trimming effort in high-volume OEM production. |
| Ratiometric output | Output scales with supply voltage, allowing direct interface with ADCs sharing the same reference - simplifies power domain partitioning. |
| ±0.1% pressure hysteresis | Ensures repeatable readings during cyclic pressure loading (e.g., respiratory monitoring), critical for diagnostic repeatability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5004DP | Higher full-scale range (4 kPa to 103 kPa), integrated signal conditioning, I²C output - replaces analog front-end complexity with digital interface. | Targets smart sensors requiring microcontroller integration; lacks raw analog output flexibility of MPX2050DP. | Select MPXV5004DP when digital output, wider pressure range, and onboard ADC are prioritized over analog signal chain control. |
| SDX100D4 | Same 0–50 kPa range and dual-port differential configuration, but uses ceramic substrate and offers improved long-term stability (±0.1% FS/year vs ±0.5% FS/year for MPX2050DP). | Better suited for field-deployed equipment requiring multi-year calibration retention without recalibration. | Select SDX100D4 when extended service life and reduced maintenance intervals outweigh cost sensitivity in industrial instrumentation. |
Compared with MPX2050DP, MPXV5004DP shifts system architecture toward digital integration while sacrificing analog design freedom, whereas SDX100D4 trades higher unit cost for superior aging performance in fixed-installation applications.

FAQ
What is the pressure port configuration of the MPX2050DP?
The MPX2050DP features two isolated pressure ports: P1 (pressure side, identified by part marking on the package) and P2 (vacuum side). It is configured for true differential measurement where output voltage increases with increasing pressure on P1 relative to P2, or increasing vacuum on P2 relative to P1. This dual-port layout enables flexible referencing in sealed or vented systems.
Does the MPX2050DP require external calibration for typical applications?
No - the MPX2050DP undergoes factory laser trimming for span and offset, and includes on-chip temperature compensation over 0°C to +85°C. For most applications within its specified operating range (e.g., pump control or level indication), no external calibration is needed. However, high-accuracy medical implementations may apply secondary software compensation using published TCOffset and TCVFSS coefficients from the datasheet.
Can the MPX2050DP be used with supply voltages other than 10 V?
Yes - the MPX2050DP operates ratiometrically with supply voltage ranging from unspecified minimum up to 16 V DC. At 10 V, full-scale output is typically 40 mV; at 5 V, it drops to ~20 mV. Operating above 10 V increases self-heating, potentially introducing additional error not covered by the standard temperature compensation, so 10 V is recommended for highest accuracy in MPX2050DP designs.
What is the maximum pressure the MPX2050DP can withstand without damage?
The MPX2050DP has a maximum pressure rating of 200 kPa (P1 > P2), which is four times its full-scale range of 50 kPa. Exceeding 200 kPa may cause permanent mechanical deformation of the silicon diaphragm or bond wire failure. For applications with potential overpressure events, external mechanical limiters or relief valves are recommended to protect the MPX2050DP.
Is the MPX2050DP compatible with non-air pressure media?
The MPX2050DP's qualification and operating characteristics are based on dry air as the pressure medium. Exposure to liquids, corrosive gases, or particulate-laden media may degrade long-term reliability or cause silicone gel contamination. Freescale explicitly advises contacting factory support before deploying MPX2050DP with any non-air media - compatibility must be validated per application, as material interactions are not characterized in the public datasheet.
