Product details
Overview
MPX5700DP from NXP Semiconductors (formerly Freescale) is a differential silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric 0.2–4.7 V analog output across a 15–700 kPa pressure range, operates from 4.75–5.25 V supply, consumes ≤10 mA, and maintains ±2.5% full-scale accuracy over –40°C to +125°C - ideal for microcontroller-based HVAC, medical pneumatic, and industrial process monitoring systems.
For engineers reviewing the MPX5700DP datasheet, MPX5700DP pinout, MPX5700DP application, or MPX5700DP equivalent, this page provides verified technical context, validated pin functions, real-world use cases in differential pressure sensing, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MPX5700DP integrates a monolithic silicon shear-stress strain gauge with thin-film metallization and bipolar signal conditioning circuitry. Its architecture includes dual gain stages, on-chip temperature compensation, and a ground-reference shift circuit - enabling stable output without external calibration components.
This differential configuration features two isolated ports (P1 and P2), with P1 designated as the positive pressure side (marked side) and P2 as vacuum/low-pressure side. The device uses dry air as the reference pressure medium and requires no external decoupling beyond the recommended 1.0 µF + 0.01 µF + 470 pF RC network at VS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–700 kPa differential; enables precise measurement of airflow, filter clogging, or liquid level differentials in sealed systems. |
| Output Voltage | 0.2–4.7 V ratiometric to 5.0 V supply; directly interfaces with 10-bit+ ADCs without scaling amplifiers. |
| Accuracy | ±2.5% VFSS over 0–85°C; includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset contributions. |
| Response Time | 1.0 ms (10%–90%); supports dynamic pressure monitoring in fast-cycling pneumatic valves or compressor control loops. |
| Supply Current | 7.0 mA typical; allows integration into low-power battery-operated devices with duty-cycled sampling. |
| Operating Temp | –40°C to +125°C; qualified for under-hood automotive, industrial enclosures, and medical equipment environments. |
| Sensitivity | 6.4 mV/kPa; provides high-resolution detection of sub-kPa pressure changes in sensitive respiratory applications. |
Pinout & Package
MPX5700DP uses Case 867C-05: unibody epoxy package with two axial ports (P1 and P2), 6-pin SIP leadform, and marking-side identification for P1. Dimensions: 18.42 × 12.57 × 5.59 mm (L×W×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Analog output voltage proportional to (P1 – P2); referenced to GND and ratiometric to VS. |
| 2 | GND | Analog ground return; must be connected to system AGND with low-impedance path to minimize noise. |
| 3 | VCC | Positive supply input (4.75–5.25 V); requires local 1.0 µF ceramic + 0.01 µF film decoupling per datasheet Fig. 4. |
| 4 | V1 | No-connect (NC); internally unconnected; must be left floating or tied to GND per layout guidelines. |
| 5 | V2 | No-connect (NC); internally unconnected; must be left floating or tied to GND per layout guidelines. |
| 6 | VEX | No-connect (NC); internal test node; not for user connection; leave unconnected. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7002DP | Lower full-scale range (0–2 kPa), higher sensitivity (15 mV/kPa), same Case 867C-05 package but updated MEMS die. | Better suited for ultra-low-pressure applications like CPAP mask leak detection; insufficient for 700 kPa HVAC/compressor use. | Select MPXV7002DP only when measuring sub-10 kPa differentials where resolution >1 Pa is required. |
| SDP800-500PA | Digital I²C output, 0–500 Pa range, integrated zero-point calibration, smaller SMD package (5.0 × 5.0 × 1.5 mm). | Designed for low-power IoT air quality sensors; lacks analog output, high-voltage tolerance, and 700 kPa capability. | Choose SDP800-500PA for battery-powered wireless nodes needing digital interface and <1 kPa range - not for MPX5700DP's industrial pressure class. |
Compared with MPX5700DP, MPXV7002DP offers finer resolution at low pressures but cannot reach 700 kPa, while SDP800-500PA trades analog simplicity and ruggedness for digital convenience and miniaturization - making MPX5700DP the only choice for high-range, analog, industrial-grade differential sensing.

FAQ
What is the pressure media compatibility of the MPX5700DP?
The MPX5700DP is qualified for use with dry air as the pressure medium. Exposure to other media - including liquids, oils, or corrosive gases - may degrade long-term performance or cause permanent damage. Freescale explicitly states that media other than dry air may adversely affect sensor reliability. For non-dry-air applications, consult NXP's factory for compatibility testing data before deployment. The MPX5700DP must never be used with wet or condensing media unless validated by NXP.
Can the MPX5700DP be used in absolute pressure mode?
No - the MPX5700DP is exclusively a differential pressure sensor with two isolated ports (P1 and P2). It does not function as an absolute pressure sensor. Absolute variants such as MPX5700A or MPX5700AS use different internal structures and port configurations. Attempting to seal P2 to vacuum or atmosphere will invalidate calibration and exceed specified accuracy limits. The MPX5700DP's transfer function and error budget assume differential operation only.
What is the correct PCB layout practice for MPX5700DP power decoupling?
Per Freescale's Figure 4, the MPX5700DP requires a three-capacitor decoupling network at the VS pin: 1.0 µF ceramic (X7R), 0.01 µF film (polyester), and 470 pF ceramic in parallel, placed within 5 mm of the VCC pin. Ground connections must route directly to a solid analog ground plane. No vias should be placed between decoupling caps and pins. This network suppresses high-frequency noise and prevents output instability - skipping any capacitor degrades accuracy and increases susceptibility to EMI in motor-driven or switching-power environments.
How is pressure side identification performed on the MPX5700DP package?
The MPX5700DP identifies its positive pressure side (P1) as the side bearing the part marking (e.g., "MPX5700DP" laser etch). This is explicitly defined in the Pressure/Vacuum Side Identification Table on page 5 of the datasheet. P2 (vacuum/low-pressure side) is the opposite port. Incorrect orientation - applying pressure to P2 instead of P1 - violates the P1 > P2 design constraint and causes saturation or irreversible offset drift. Always verify port orientation using the marked side before mechanical mounting.
Does the MPX5700DP require external calibration after soldering?
No - the MPX5700DP is fully calibrated at the wafer level and temperature-compensated during manufacturing. Its ±2.5% accuracy specification includes all contributions (linearity, hysteresis, TcSpan, TcOffset) over 0–85°C and requires no end-user trimming, software correction, or external reference. However, mechanical stress from PCB flexure or uneven mounting torque can induce offset errors; follow NXP's recommended gasketed mounting procedure and avoid overtightening screws. The MPX5700DP delivers calibrated output straight from the board.
