Product details
Overview
MPX53GP from Freescale Semiconductor is a silicon piezoresistive gauge pressure sensor with 0–50 kPa range, ratiometric 3.0–6.0 VDC supply operation, 60 mV typical full-scale span, and dual-port unibody package (Case 98ASB14911C). It delivers linear differential voltage output for pneumatic control, medical instrumentation, and industrial level sensing where external temperature compensation is applied.
For engineers reviewing the MPX53GP datasheet, MPX53GP pinout, MPX53GP application, or MPX53GP equivalent, this page provides verified mechanical dimensions, confirmed pin functions, validated operating characteristics across –40°C to +125°C, and real-world substitution guidance for uncompensated gauge pressure sensing designs.
Technical Context
The MPX53GP uses a patented transverse-voltage diffused silicon strain gauge integrated into a thin diaphragm, eliminating thermal expansion mismatch errors common in bonded gauges. Its ratiometric output scales directly with supply voltage, enabling simplified signal conditioning when paired with matching ADC references.
It operates exclusively in gauge configuration with P1 (pressure) side identified by the port-attached surface and P2 (vacuum/reference) side sealed internally. Output is differential: +VOUT and –VOUT pins deliver opposing polarity signals relative to GND, supporting noise-rejecting instrumentation amplifier interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–50 kPa gauge - supports low-pressure pneumatic and vacuum-relative measurements up to ~7.25 psi. |
| Full-Scale Span | 45–90 mV (typ. 60 mV) - defines usable analog output swing; enables 12-bit+ resolution with appropriate gain. |
| Supply Voltage | 3.0–6.0 VDC - ratiometric behavior ensures output scaling matches reference voltage, reducing supply sensitivity. |
| Operating Temp | –40°C to +125°C - qualified for harsh industrial and automotive under-hood environments without internal compensation. |
| Response Time | 1.0 ms (10%–90%) - suitable for dynamic pressure monitoring in fast-cycling valves or airflow control loops. |
| Linearity Error | ±0.6% VFSS (end-point fit) - sets worst-case deviation budget for calibration-critical applications like medical flow meters. |
| Offset Stability | ±0.5% VFSS after 1000 hrs pulsed stress - confirms long-term baseline reliability in continuously monitored systems. |
Pinout & Package
MPX53GP uses the unibody chip carrier package Case 98ASB14911C (4-pin, 2.9 mm × 1.7 mm footprint), with port attached on the P1 side and notch-aligned pin 1 identification. The package integrates silicone gel isolation for environmental protection while transmitting pressure to the silicon diaphragm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for supply and output; pin 1 identified by notch on package edge. |
| 2 | +VOUT | Positive differential output terminal; voltage rises with increasing P1 pressure relative to P2. |
| 3 | VS | Supply input (3.0–6.0 VDC); powers piezoresistive bridge and sets output scale via ratiometric relationship. |
| 4 | –VOUT | Negative differential output terminal; complements +VOUT for true differential readout and common-mode noise rejection. |
Key Features
| Feature | Design Value |
|---|---|
| Patented silicon shear-stress strain gauge | Eliminates thermal drift from CTE mismatch-enables stable baseline over wide temperature ranges without complex compensation. |
| Ratiometric output | Output voltage scales linearly with VS; allows direct interface with ratiometric ADCs, removing supply regulation dependency. |
| Dual-port gauge configuration | P1 side has physical port for pressure connection; P2 side is sealed reference cavity-ideal for absolute atmospheric-referenced measurement. |
| Unibody chip carrier package | Hermetically sealed with silicone gel encapsulation-provides moisture and particulate protection while maintaining pressure transmission fidelity. |
| Low warm-up time | 20 ms stabilization after power-on-supports rapid system startup in battery-powered or duty-cycled instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5050GP | Higher 0–500 kPa range; same 4-pin unibody package (98ASB14911C); improved TCVOFF (±5 µV/°C vs. ±15 µV/°C). | Designed for mid-range industrial pressure; less sensitive to low-end resolution than MPX53GP in sub-100 kPa use cases. | Select MPX5050GP only if system requires >50 kPa headroom or tighter offset drift control; not a drop-in replacement due to different span and calibration. |
| MPXV5004GP | Integrated signal conditioning and temperature compensation; 0–4 kPa range; 3.3 V supply; analog output only (single-ended). | Targeted at consumer-grade HVAC and appliance sensing; lacks differential output and wide temp range (–40°C to +125°C). | Choose MPXV5004GP for cost-sensitive, low-pressure applications where external compensation is impractical-but requires PCB redesign and firmware adaptation. |
Compared with MPX53GP, MPX5050GP trades low-end sensitivity for extended range and better offset stability, while MPXV5004GP sacrifices differential output and ruggedness for plug-and-play simplicity in benign environments-making MPX53GP optimal for uncompensated, high-fidelity 0–50 kPa gauge measurement where design flexibility is prioritized.

FAQ
What is the pressure port configuration of the MPX53GP?
The MPX53GP uses a dual-port gauge configuration: the P1 (pressure) side features a physical port for external pressure connection, while the P2 (vacuum/reference) side is sealed internally to ambient atmospheric pressure. Per Freescale documentation, the P1 side is identified by the "side with port attached" on Case 98ASB14911C packaging. This arrangement enables true gauge pressure measurement referenced to local atmosphere.
Does the MPX53GP include built-in temperature compensation?
No, the MPX53GP is an uncompensated silicon pressure sensor. It requires external temperature compensation circuitry-such as resistor networks or microcontroller-based algorithms-to correct for TCVOFF (±15 µV/°C) and TCVFSS (–0.22 to –0.16 %VFSS/°C). Freescale Application Note AN840 details practical compensation methods for –40°C to +125°C operation, and the MPX53GP's predictable single-element strain gauge simplifies this design task.
What is the meaning of "ratiometric" in MPX53GP specifications?
"Ratiometric" means the MPX53GP's output voltage scales linearly with its supply voltage (VS = 3.0–6.0 VDC). For example, at 3.0 V supply, typical full-scale span is 60 mV; at 6.0 V supply, it becomes ~120 mV. This behavior allows direct interfacing with ratiometric ADCs-where the same VS supplies both sensor and ADC reference-eliminating errors from supply variation and simplifying system-level calibration.
Can the MPX53GP be used for differential pressure measurement?
No-the MPX53GP is specified and packaged exclusively for gauge pressure measurement (P1 relative to ambient). Although it provides differential output terminals (+VOUT and –VOUT), both are referenced to the internal P2 cavity-not an external second pressure port. For true differential measurement (P1 vs. P2), the MPX53DP variant-featuring two external ports-is required. Using MPX53GP in differential mode would yield invalid or unstable readings.
What is the maximum pressure rating and burst pressure for the MPX53GP?
The MPX53GP has a maximum operating pressure (P1 > P2) of 175 kPa and a burst pressure rating of 200 kPa, as specified in Freescale's MPX53 datasheet Rev. 7.1. These limits apply under standard conditions using dry air as the pressure medium. Exceeding 175 kPa during normal operation risks permanent performance degradation, while exposure beyond 200 kPa may cause mechanical failure of the silicon diaphragm or package seal.
