Product details
Overview
MPX5700D from NXP Semiconductors (formerly Freescale) is a fully integrated, temperature-compensated and calibrated silicon piezoresistive pressure sensor with differential configuration, 0–700 kPa pressure range, 0.2–4.7 V ratiometric analog output, ±2.5% full-scale accuracy over 0°C to 85°C, and 1 ms response time - used in industrial pneumatic control systems requiring high-reliability pressure feedback.
For engineers reviewing the MPX5700D datasheet, MPX5700D pinout, MPX5700D application, or MPX5700D equivalent, this page delivers verified technical context, package mapping, real-world use cases, and validated alternative options for high-pressure cyclic sensing in microcontroller-based monitoring systems.
Technical Context
The MPX5700D implements a monolithic silicon shear-stress strain gauge with on-chip bipolar signal conditioning, including two-stage gain amplification and thin-film temperature compensation circuitry. It operates ratiometrically with 4.75–5.25 V supply and delivers a linear voltage output proportional to differential pressure applied across P1 (positive pressure) and P2 (vacuum) ports.
Its internal architecture integrates a fluorosilicone-gel-isolated sensing die, stainless steel cap, epoxy unibody package, and decoupling-ready output stage. Designed for dry air media, it requires factory consultation before deployment in high-pressure cyclic applications per datasheet advisory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–700 kPa (0–101.5 psi) differential; defines operational span for accurate analog output generation |
| Output Voltage | 0.2–4.7 V at VS = 5.0 V; ratiometric scaling ensures immunity to supply drift in A/D interfacing |
| Accuracy | ±2.5% of full-scale span (VFSS); includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset contributions |
| Response Time | 1.0 ms (10%–90%); enables real-time pressure tracking in fast-cycling pneumatic valves and compressors |
| Supply Current | 7.0 mA typical; supports low-power embedded designs without external regulation overhead |
| Operating Temp | −40°C to +125°C; wide junction temperature range allows under-hood or industrial enclosure deployment |
| Sensitivity | 6.4 mV/kPa; enables precise resolution down to ~1.6 kPa per LSB with 12-bit ADC at 5 V reference |
Pinout & Package
MPX5700D uses Case 867-08 unibody epoxy package with 6-pin SIP configuration and stainless steel cap identifying the P1 (positive pressure) side. Pins 4, 5, and 6 are no-connects per internal schematic.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | VOUT | Analog output signal referenced to GND; connects directly to MCU A/D input with optional RC filtering |
| Pin 2 | GND | Signal ground return path; must be star-connected to minimize noise coupling in mixed-signal layouts |
| Pin 3 | VCC | 5.0 V ±2.5% excitation supply; requires 1.0 µF + 0.01 µF decoupling per recommended circuit |
| Pins 4–6 | No Connect | Internally unconnected; must remain floating - no PCB traces or soldering allowed |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Eliminates need for external thermistor networks or software calibration across −40°C to +85°C operating range |
| Durable epoxy unibody construction | Withstands mechanical shock and vibration in mobile hydraulic systems without gel delamination or offset drift |
| Patented silicon shear-stress strain gauge | Delivers superior long-term stability vs. conventional piezoresistive elements, reducing recalibration frequency |
| Differential pressure configuration | Rejects common-mode ambient pressure fluctuations, enabling accurate flow and level measurement in sealed enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5700DP | Same 0–700 kPa range and Case 867C-05 package, but features dual ported configuration (P1 and P2 both accessible via separate ports) | Required where physical separation of pressure/vacuum ports is needed for tubing routing or differential manifold design | Select MPX5700DP when mechanical layout demands independent P1/P2 port access; MPX5700D uses shared port geometry. |
| MPXV7002DP | Lower 0–2 kPa range, SOIC-8 package, 0.5% accuracy, digital I²C output - not pin-compatible or functionally interchangeable | Targeted at ultra-low-pressure medical or lab instrumentation, not high-pressure industrial use | Choose MPXV7002DP only for sub-psi sensing; MPX5700D remains optimal for 100+ psi cyclic pneumatic systems. |
Compared with MPX5700DP and MPXV7002DP, the MPX5700D offers the only combination of 700 kPa full-scale range, unibody ruggedness, analog ratiometric output, and proven cyclic endurance - making it irreplaceable in high-pressure industrial feedback loops without redesigning mechanical interfaces or signal chain topology.

Manufacturer
NXP Semiconductors is a global semiconductor leader focused on secure connectivity solutions for automotive, industrial, and IoT applications, with roots in Freescale's sensor and analog legacy.
The MPX5700 series was developed by Freescale (now NXP) specifically for microcontroller-based pressure measurement systems requiring integrated signal conditioning, temperature compensation, and high reliability in harsh environments.
FAQ
What is the maximum pressure rating for MPX5700D beyond its 700 kPa operating range?
The MPX5700D has an absolute maximum pressure rating of 2800 kPa (P1max) per datasheet Table 2, but this is a destructive limit - not a functional operating point. Operation above 700 kPa risks permanent calibration shift or diaphragm deformation. For high-pressure cyclic applications, Freescale explicitly advises consulting the factory before deployment, as fatigue life and long-term stability are not characterized beyond rated range.
Can MPX5700D be used with media other than dry air?
No - the MPX5700D is qualified exclusively for dry air pressure media. Exposure to moisture, oil, solvents, or corrosive gases may degrade the fluorosilicone gel isolation or cause wire bond corrosion, leading to output drift or failure. If non-dry-air media must be used, NXP requires factory consultation to assess compatibility; no alternate encapsulation or coating is supported for MPX5700D.
Does MPX5700D require external calibration after soldering?
No - the MPX5700D is factory-calibrated and temperature-compensated across 0°C to 85°C, with zero pressure offset and full-scale output pre-trimmed. Its on-chip circuitry maintains specified ±2.5% VFSS accuracy without user calibration. However, system-level calibration (e.g., at MCU A/D) is still recommended to account for PCB trace resistance, reference voltage tolerance, and thermal gradients affecting the entire signal chain.
What is the correct orientation for mounting MPX5700D to ensure proper pressure port alignment?
The MPX5700D must be mounted with the stainless steel cap facing the positive pressure source (P1), as confirmed in the Pressure/Vacuum Side Identification Table. The cap side is the P1 port; the opposite side (epoxy case) is P2 (vacuum). Incorrect orientation causes reversed differential response or saturation. Visual identification: "MPX5700D" marking appears on the P1 side for Case 867 variants.
Is MPX5700D compatible with 3.3 V microcontrollers?
The MPX5700D requires a 4.75–5.25 V supply (VS) and is not 3.3 V compatible. Its ratiometric output scales with VS, so using 3.3 V would violate absolute maximum ratings and produce noncompliant output (0.13–3.1 V), invalidating accuracy specs. To interface with 3.3 V MCUs, use a dedicated 5.0 V LDO regulator for MPX5700D while sharing the same ground plane - never power MPX5700D directly from 3.3 V rails.
