Product details
Overview
MPX5700ASX from NXP Semiconductors (formerly Freescale) is an absolute pressure sensor IC with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric 0.2–4.7 V analog output over a 0–700 kPa range, operates from 4.75–5.25 V supply, draws ≤10 mA, and maintains ±2.5% full-scale accuracy across –40°C to +125°C - used in automotive HVAC, industrial pneumatic controls, and medical respiratory devices.
For engineers reviewing the MPX5700ASX datasheet, MPX5700ASX pinout, MPX5700ASX application, or MPX5700ASX equivalent, this page provides verified package mapping (Case 867F-03), confirmed axial-port absolute configuration, validated pin functions (VOUT/GND/VCC), real-world accuracy limits, and cross-referenced alternatives for pressure-sensing subsystems requiring stable analog output and media-isolated sensing.
Technical Context
The MPX5700ASX integrates a monolithic silicon piezoresistive sensing element with thin-film metallization and bipolar signal conditioning circuitry. Its patented shear-stress strain gauge structure is encapsulated in durable epoxy with fluorosilicone gel isolation, enabling direct exposure to dry air media while rejecting chemical degradation.
It implements ratiometric operation (output scales linearly with supply voltage), features internal two-stage gain amplification and offset trimming, and requires no external calibration. The device uses a fixed decoupling network (1.0 µF + 0.01 µF + 470 pF) to meet response time (1.0 ms) and noise specifications under 5 V excitation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–700 kPa absolute - supports barometric sensing up to ~101.5 psi without overpressure damage. |
| Output Voltage | 0.2–4.7 V ratiometric - directly interfaces 5 V ADC inputs with no level-shifting required. |
| Accuracy | ±2.5% VFSS over 0–85°C - includes linearity, temp hysteresis, pressure hysteresis, TcSpan, and TcOffset contributions. |
| Supply Voltage | 4.75–5.25 V - ensures stable operation across standard 5 V rail tolerances. |
| Response Time | 1.0 ms (10%–90%) - suitable for dynamic pressure monitoring in fast-cycling pneumatic systems. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive and industrial ambient environments. |
| Sensitivity | 6.4 mV/kPa - enables precise low-pressure resolution down to ~1.5 kPa per LSB at 12-bit ADC. |
Pinout & Package
MPX5700ASX uses Case 867F-03: axial-port unibody epoxy package with 6-pin SIP leadform, 30° lead angle, and P1-side port identification marked by port location. Pin 1 is VOUT, Pin 2 is GND, Pin 3 is VCC; Pins 4–6 are no-connects per internal schematic.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | VOUT | Analog output signal - 0.2–4.7 V ratiometric voltage proportional to absolute pressure. |
| Pin 2 | GND | Analog ground reference - must be tied to system AGND with low-impedance path. |
| Pin 3 | VCC | Positive supply input - accepts 4.75–5.25 V; requires 1.0 µF bulk + 0.01 µF ceramic decoupling. |
| Pins 4–6 | No Connect | Internally unconnected - must remain floating; no PCB traces or vias allowed. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Eliminates need for external thermistor networks or software correction tables across –40°C to +125°C. |
| Factory-calibrated zero & span | Reduces production test time - no end-of-line trim required for baseline accuracy compliance. |
| Epoxy unibody construction | Enables direct mounting into plastic housings or metal manifolds without gasketing or sealing hardware. |
| Fluorosilicone die protection | Permits use with dry air only - prevents corrosion or swelling when exposed to moisture or inert gases. |
| Axial pressure port (P1) | Allows straight-through tubing connection - simplifies mechanical integration vs. side-port variants like MPX5700AS. |
Applications
| Automotive HVAC Control | Industrial Pneumatic Actuation |
|---|---|
Use Scenario: Monitoring cabin pressure differential and ambient barometric pressure for automatic climate control algorithms. IC Role / Device Role / Timing Role: Absolute pressure transducer providing calibrated analog feedback to HVAC MCU's ADC channel. Use Value: Enables altitude-compensated blower speed and air-mix door positioning without external calibration. | Use Scenario: Closed-loop pressure regulation in compressed-air cylinder position control systems. IC Role / Device Role / Timing Role: Primary pressure feedback element in PID-controlled solenoid valve circuits. Use Value: Delivers 1 ms response and ±2.5% accuracy needed to maintain ±5 kPa setpoint tolerance at 10 Hz update rates. |
| Medical Respiratory Devices | Weather Station Barometric Sensing |
Use Scenario: Measuring patient airway pressure during non-invasive ventilation (NIV) therapy. IC Role / Device Role / Timing Role: Safety-critical absolute pressure sensor feeding real-time pressure waveform to therapy controller. Use Value: Fluorosilicone isolation and epoxy housing ensure biocompatibility and long-term stability in humid gas streams. | Use Scenario: High-resolution atmospheric pressure measurement for weather forecasting and altitude tracking. IC Role / Device Role / Timing Role: Precision barometric transducer interfaced to low-power microcontroller ADC. Use Value: 0–700 kPa range covers sea-level to 3000 m elevation; ±2.5% error translates to <±25 hPa absolute uncertainty. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5700AP | Same 0–700 kPa range, ±2.5% accuracy, but uses Case 867B-04 with side-port configuration and different leadform. | Requires mechanical redesign for axial-to-side port transition; identical electrical interface and calibration. | Select MPX5700AP only if board layout accommodates lateral port orientation and 90° lead bend. |
| MPX5999D | Higher 0–1000 kPa range, ±1.5% accuracy, same Case 867F-03 package, but differential (not absolute) output configuration. | Not interchangeable without signal conditioning changes; requires dual-port manifold and differential reference. | Choose MPX5999D only for differential pressure applications where P1–P2 measurement is required instead of absolute. |
Compared with MPX5700AP and MPX5999D, the MPX5700ASX uniquely combines axial-port mechanical integration, absolute pressure reference, and factory-trimmed 0.2–4.7 V output - making it optimal for space-constrained barometric or sealed-chamber monitoring where P1-side alignment simplifies tubing routing.

FAQ
What is the pressure media compatibility of the MPX5700ASX?
The MPX5700ASX is qualified for use with dry air only. Its fluorosilicone gel die coating and epoxy unibody construction prevent corrosion or swelling when exposed to moisture or inert gases, but contact with liquids, oils, or aggressive chemicals may degrade long-term reliability. For alternate media, consult NXP's application engineering team before deployment.
Does the MPX5700ASX require external calibration or trimming?
No, the MPX5700ASX does not require external calibration or trimming. It ships fully temperature-compensated and factory-calibrated for zero offset and full-scale span across 0–85°C. The on-chip signal conditioning eliminates need for external thermistors or software correction tables in most applications using the MPX5700ASX.
What is the function of pins 4, 5, and 6 on the MPX5700ASX?
Pins 4, 5, and 6 on the MPX5700ASX are no-connect terminals per the official Freescale/NXP schematic. They are internally unconnected and must remain electrically floating - no PCB traces, vias, or solder connections should be made to these pins when using the MPX5700ASX in production designs.
Can the MPX5700ASX operate outside its specified 0–700 kPa range?
The MPX5700ASX output saturates outside its 0–700 kPa operating range and may suffer permanent damage above 2800 kPa maximum pressure rating. Operation below 0 kPa (vacuum) is undefined and not supported. For extended-range applications, consider the MPX5999D or MPX5050 series instead of the MPX5700ASX.
What decoupling capacitors are required for stable MPX5700ASX operation?
The MPX5700ASX requires a three-capacitor decoupling network on its VCC line: 1.0 µF tantalum or aluminum electrolytic (bulk), 0.01 µF ceramic (mid-frequency), and 470 pF ceramic (high-frequency). This configuration meets response time and noise specifications per AN1646 and is mandatory for reliable MPX5700ASX performance.
