Product details
Overview
MPX53DP from Freescale Semiconductor is a differential silicon piezoresistive pressure sensor with 0–50 kPa range, ratiometric 3.0–6.0 V supply operation, 60 mV typical full-scale span, and unibody package (Case 98ASB14912C). It delivers linear voltage output proportional to differential pressure (P1 > P2) and requires external temperature compensation for precision applications such as medical instrumentation and pneumatic control.
For engineers reviewing the MPX53DP datasheet, MPX53DP pinout, MPX53DP application, or MPX53DP equivalent, key selection considerations include its dual-port differential configuration, ±0.1%VFSS pressure hysteresis, –40°C to +125°C operating temperature, and need for external signal conditioning networks.
Technical Context
The MPX53DP uses a patented transverse-voltage diffused silicon strain gauge integrated into a thin diaphragm, eliminating thermal expansion mismatch errors common in bonded-gauge sensors. Its ratiometric output scales directly with supply voltage, enabling stable performance when paired with a regulated reference.
It operates exclusively in differential mode (P1 > P2), with pressure ports identified by marking on the Case 98ASB14912C package. Output impedance (750–1875 Ω) and input impedance (355–505 Ω) require careful interface design to avoid loading errors, and response time is specified at 1.0 ms (10%–90%).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 50 kPa differential (P1 > P2); defines usable sensing window without saturation or damage. |
| Full-Scale Span | 45–90 mV (typ. 60 mV); determines analog-to-digital resolution and gain requirements in signal chain. |
| Supply Voltage | 3.0–6.0 VDC; ratiometric operation means output scales linearly with VS, simplifying reference design. |
| Linearity Error | ±0.6%VFSS (end-point fit); sets worst-case deviation from ideal linear transfer function over full range. |
| Response Time | 1.0 ms (10% to 90%); supports dynamic pressure monitoring up to ~350 Hz bandwidth. |
| Operating Temp | –40°C to +125°C; enables use in industrial and automotive under-hood environments without derating. |
| Offset Voltage | 0–35 mV at 0 kPa; requires calibration or trimming circuitry to achieve zero-pressure baseline accuracy. |
Pinout & Package
MPX53DP is housed in a unibody chip carrier package (Case 98ASB14912C), featuring dual pressure ports, silicone gel isolation of die and wire bonds, stainless steel metal cover, and 4-pin lead frame. Pin 1 is identified by notch and marked "GND".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Reference ground for supply and output; must be low-impedance path to minimize noise coupling. |
| 2 | +VOUT | Positive differential output terminal; voltage increases with increasing P1–P2 pressure difference. |
| 3 | VS | Supply voltage input (3.0–6.0 VDC); powers internal Wheatstone bridge and defines output scale. |
| 4 | –VOUT | Negative differential output terminal; used with +VOUT to extract differential voltage across bridge. |
Key Features
| Feature | Design Value |
|---|---|
| Silicon shear stress strain gauge | Monolithic integration eliminates thermal drift from CTE mismatch-critical for long-term stability in wide-temp applications. |
| Ratiometric output | Output voltage scales linearly with supply voltage, allowing shared reference between sensor and ADC for improved system-level accuracy. |
| Dual-port differential configuration | Enables true differential pressure measurement (e.g., airflow across filter, liquid level via head pressure) without absolute reference dependency. |
| Unibody package with port marking | Case 98ASB14912C clearly identifies P1 side via marking-reducing assembly error in production and field service. |
| Low response time (1.0 ms) | Supports real-time closed-loop control in robotics and pneumatic systems where rapid pressure feedback is required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5050DP | Higher 0–500 kPa range, integrated temperature compensation, 5 V supply only, same Case 98ASB14912C footprint. | Used where wider range and factory-trimmed accuracy eliminate need for external compensation network. | Select MPX5050DP if system lacks space or resources for external temp compensation circuitry. |
| MPXV5004DP | 0–4 kPa range, built-in signal conditioning, 5 V supply, SOIC-8 package-not pin-compatible. | Targeted at ultra-low-pressure applications like respiratory flow sensing where sub-kPa resolution is critical. | Choose MPXV5004DP only when pressure range is <5 kPa and board layout allows SOIC-8 rework. |
Compared with MPX53DP, MPX5050DP offers plug-and-play operation but sacrifices design flexibility and multi-supply support; MPXV5004DP provides higher resolution at low pressures but cannot replace MPX53DP in 0–50 kPa systems without range or interface redesign.

FAQ
What is the pressure port configuration of the MPX53DP?
The MPX53DP features two dedicated pressure ports in differential configuration: P1 (pressure side, identified by port marking on Case 98ASB14912C) and P2 (vacuum side). It is rated for P1 > P2 operation only, with maximum differential pressure of 175 kPa and burst rating of 200 kPa. The MPX53DP does not support gauge or absolute configurations - those are handled by MPX53GP and MPX53D variants respectively.
Does the MPX53DP include built-in temperature compensation?
No, the MPX53DP is an uncompensated silicon pressure sensor. Its output exhibits temperature-dependent full-scale span drift (–0.22 to –0.16 %VFSS/°C) and offset drift (±15 µV/°C), requiring external resistive networks or active circuitry for compensation across –40°C to +125°C. Freescale Application Note AN840 details proven methods for implementing this externally, and the MPX53DP's predictable single-element strain gauge simplifies that design effort.
What is the electrical interface requirement for the MPX53DP?
The MPX53DP requires a 3.0–6.0 VDC supply (VS), draws up to 6.0 mA, and delivers a differential analog output (+VOUT and –VOUT) with 750–1875 Ω output impedance. To preserve accuracy, the interface must use a high-input-impedance differential amplifier or instrumentation amplifier - direct connection to most ADC inputs will load the output and distort readings. Input impedance is 355–505 Ω, limiting drive capability.
Can the MPX53DP be used with media other than dry air?
Freescale specifies MPX53DP performance and reliability based on dry air as the pressure medium. Use with other gases or liquids may degrade long-term stability or cause corrosion, especially if moisture, oils, or reactive chemicals contact the silicone gel-isolated die. For non-air media, consult Freescale Application Note AN3728 on media compatibility - it outlines material limitations and qualification requirements before deployment in medical, hydraulic, or chemical environments.
What is the meaning of "unibody package" for the MPX53DP?
The MPX53DP uses a unibody chip carrier package (Case 98ASB14912C) where the stainless steel metal cover, lead frame, and port structure form a single integrated mechanical unit - no separate gaskets or seals are required. This improves hermeticity, mechanical robustness, and long-term reliability in vibration-prone environments. The silicone gel encapsulant protects the die and wire bonds while transmitting pressure to the silicon diaphragm, and the port marking on the P1 side aids correct orientation during assembly.
