Product details
Overview
MPX5700AS from NXP Semiconductors (formerly Freescale) is a silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration for absolute pressure measurement. It delivers a ratiometric 0.2–4.7 V analog output over 0–700 kPa (0–101.5 psi), operates from 4.75–5.25 V supply, draws ≤10 mA, and maintains ±2.5% full-scale accuracy across –40°C to +125°C. It is used in HVAC airflow monitoring, medical pneumatic controls, and industrial process pressure feedback loops.
For engineers reviewing the MPX5700AS datasheet, MPX5700AS pinout, MPX5700AS application, or MPX5700AS equivalent, key selection criteria include its absolute pressure configuration, Case 867E-03 unibody epoxy package with single port on the P1 side, 1 ms response time, and compatibility with microcontroller A/D inputs requiring stable, calibrated analog pressure signals.
Technical Context
The MPX5700AS integrates a micromachined silicon diaphragm with thin-film piezoresistors, bipolar gain stages, on-die temperature compensation circuitry, and a ground-referenced output amplifier. Its transfer function is VOUT = VS × (0.0012858 × P + 0.04), where VS = 5.0 V and P is pressure in kPa.
It uses fluorosilicone gel isolation to protect wire bonds and die while transmitting pressure to the sensing element. The device requires no external calibration and is qualified for operation with dry air media; alternate media require factory consultation due to potential long-term reliability impact.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–700 kPa absolute; enables direct measurement of barometric or sealed-system pressure without reference venting. |
| Output Voltage | 0.2–4.7 V ratiometric to supply; simplifies A/D conversion by eliminating need for separate voltage reference. |
| Accuracy | ±2.5% VFSS over 0–85°C; includes linearity, TCspan, TCoffset, hysteresis, and variation from nominal. |
| Response Time | 1.0 ms (10%–90%); supports dynamic pressure monitoring in fast-cycling pneumatic systems. |
| Supply Current | 7.0 mA typical at 5 V; allows low-power embedded designs with minimal thermal drift contribution. |
| Operating Temp | –40°C to +125°C; supports under-hood automotive, industrial control, and medical equipment environments. |
| Sensitivity | 6.4 mV/kPa; provides high-resolution analog output for precise pressure differentiation within full scale. |
Pinout & Package
MPX5700AS is housed in a unibody epoxy package (Case 867E-03) with a single pressure port on the P1 (positive pressure) side, stainless steel cap, and 6-pin SIP configuration. Pins 4, 5, and 6 are no-connects per internal schematic.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Analog output terminal delivering conditioned, temperature-compensated voltage proportional to absolute pressure. |
| 2 | GND | Ground reference for both supply and output; must be connected to system common with low-impedance path. |
| 3 | VCC | Positive supply input (4.75–5.25 V); powers internal amplifiers and compensation circuitry. |
| 4 | V1 | No connect - internally unused; must remain floating or tied to GND only if required by layout constraints. |
| 5 | V2 | No connect - internally unused; no electrical function; avoid routing signals or traces to this pin. |
| 6 | VEX | No connect - externally exposed but not bonded; electrically isolated from die and supply rails. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Eliminates need for external thermistor networks or software correction algorithms across –40°C to +125°C. |
| Factory-calibrated full-scale span | Delivers production-ready accuracy without end-of-line trimming or calibration fixtures. |
| Durable epoxy unibody construction | Provides mechanical robustness and moisture resistance in non-corrosive gas environments using dry air media. |

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 absolute range and Case 867B-04 package; differs in port orientation (side-mounted vs. top-mounted on MPX5700AS). | Requires PCB re-layout due to different mechanical footprint and port location; identical electrical interface. | Select MPX5700AP only when side-port geometry better suits mechanical housing constraints. |
| MPX5999D | Higher 0–1000 kPa range, ±1.5% accuracy, and Case 867C-05 dual-port differential design; not absolute-configured. | Not suitable for barometric or sealed-tank absolute measurement; requires P1/P2 differential connection. | Choose MPX5999D only for high-pressure differential applications; not a functional substitute for MPX5700AS absolute use cases. |
Compared with MPX5700AP and MPX5999D, the MPX5700AS offers optimized mechanical integration for top-ported absolute pressure measurement in space-constrained enclosures, with verified ±2.5% accuracy and 1 ms response-making it preferred for medical and HVAC applications where port orientation and absolute reference are critical.

FAQ
What is the pressure type and range supported by the MPX5700AS?
The MPX5700AS is an absolute pressure sensor with a rated range of 0–700 kPa (0–101.5 psi). It measures pressure relative to perfect vacuum and is not configurable for gauge or differential modes. This range is validated per Freescale's MPX5700 series datasheet Rev 10, with output saturation outside the specified limits.
Does the MPX5700AS require external calibration or compensation circuitry?
No, the MPX5700AS does not require external calibration or compensation. It integrates on-chip temperature compensation, factory calibration, and signal conditioning. The MPX5700AS delivers a ready-to-use 0.2–4.7 V ratiometric output directly compatible with microcontroller A/D inputs, eliminating need for thermistors, op-amps, or software correction tables.
What is the correct pin configuration and which pins are unused on the MPX5700AS?
The MPX5700AS uses Style 1 pinout: Pin 1 = VOUT, Pin 2 = GND, Pin 3 = VCC, Pin 4 = V1, Pin 5 = V2, Pin 6 = VEX. Pins 4, 5, and 6 are no-connects per the internal schematic and must remain unconnected or tied to GND only if required by mechanical layout-no electrical function is assigned to them in the MPX5700AS.
Can the MPX5700AS be used with media other than dry air?
Freescale explicitly states that MPX5700AS operating characteristics and reliability testing are based on dry air. Use with other media may degrade performance or cause long-term failure. For non-dry-air applications-including humid air, gases with condensables, or liquids-the MPX5700AS must be evaluated with factory consultation before deployment; no media compatibility data is published for alternative substances.
What decoupling is recommended for stable operation of the MPX5700AS?
Freescale recommends a decoupling network consisting of a 1.0 µF bulk capacitor, a 0.01 µF ceramic capacitor, and a 470 pF output filter capacitor between VCC and GND, placed as close as possible to the MPX5700AS pins. This configuration ensures stable power delivery and minimizes noise coupling into the analog output, especially when interfacing with microcontroller A/D converters.
