Product details
Overview
MPX5700GP from NXP Semiconductors (formerly Freescale) is a gauge-pressure silicon piezoresistive transducer with on-chip signal conditioning, temperature compensation, and factory calibration. 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 - used in HVAC airflow monitoring, industrial pneumatic control, and medical pressure-sensing subsystems.
For engineers reviewing the MPX5700GP datasheet, MPX5700GP pinout, MPX5700GP application, or MPX5700GP equivalent, this page provides verified package mapping (Case 867B-04), confirmed 6-pin Style 1 pinout (VOUT/GND/VCC/V1/V2/VEX), calibrated transfer function (Vout = VS × (0.0012858×P + 0.04)), and validated alternatives for gauge-pressure sensing in microcontroller-based systems.
Technical Context
The MPX5700GP integrates a monolithic silicon shear-stress strain gauge with thin-film metallization and bipolar signal conditioning circuitry. Its architecture includes two gain stages, on-die temperature compensation, and ground-reference shift circuitry - enabling direct interface to microcontroller ADC inputs without external amplification or compensation.
It uses fluorosilicone gel isolation to protect the die while transmitting pressure to the diaphragm, and requires dry air as the pressure medium per qualification testing. The device is unidirectional (P1 > P2), with the pressure port on the side marked "PORT #1 POSITIVE PRESSURE (P1)" per Case 867B-04 mechanical drawings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–700 kPa gauge; enables direct measurement of HVAC duct static pressure or pneumatic cylinder pressure without range scaling. |
| Output Voltage | 0.2–4.7 V at VS = 5.0 V; ratiometric output ensures immunity to supply drift when referenced to same ADC VREF. |
| Accuracy | ±2.5% VFSS over 0–85°C; covers linearity, TcOffset, TcSpan, and hysteresis error budget - sufficient for Class 2 industrial sensing. |
| Supply Current | Typ. 7.0 mA; allows low-power operation in battery-backed sensor nodes with <100 mW total dissipation. |
| Response Time | Typ. 1.0 ms (10–90%); supports real-time closed-loop control of fast-acting solenoid valves or compressors. |
| Operating Temp | –40°C to +125°C ambient; qualified for under-hood automotive and industrial enclosure environments. |
| Sensitivity | 6.4 mV/kPa; yields ~4.5 V full-scale span - simplifies 12-bit ADC resolution allocation (≈1.1 mV/LSB). |
Pinout & Package
MPX5700GP uses the Case 867B-04 unibody epoxy package with 6 leads and a single pressure port on the P1 side. Lead form is standard (MPX5700GP) or 90° bent (MPX5700GP1). Seating plane defined per ANSI Y14.5M.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Analog output voltage proportional to applied gauge pressure; directly connects to MCU ADC input with 470 pF filter per recommended decoupling. |
| 2 | GND | Analog ground reference for internal circuitry and output stage; must be star-connected to system AGND to minimize noise coupling. |
| 3 | VCC | 5.0 V ±2.5% excitation supply; ratiometric behavior ties output scale to this rail - use low-noise LDO or filtered switching supply. |
| 4 | V1 | No-connect (NC); internally unconnected - leave floating or tie to GND only if required by board layout constraints. |
| 5 | V2 | No-connect (NC); internally unconnected - no external connection required. |
| 6 | VEX | No-connect (NC); internal excitation node not exposed - must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Eliminates need for external thermistor networks or software lookup tables - reduces BOM count and calibration effort. |
| Patented silicon shear-stress strain gauge | Delivers superior long-term stability and reduced hysteresis vs. conventional piezoresistive elements - critical for maintenance-free field deployment. |
| Durable epoxy unibody construction | Withstands vibration, thermal cycling, and humidity exposure without delamination - validated for 10+ year industrial service life. |
| Ratiometric output | Output scales linearly with supply voltage - enables shared VREF between sensor and ADC, improving system-level accuracy. |
| Fluorosilicone die protection | Provides chemical compatibility with dry air and inert gases while maintaining pressure transmission fidelity - avoids media-specific derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge-pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5500GP | 0–500 kPa range, ±2.5% accuracy, same Case 867B-04 package and pinout. | Limited to lower-pressure HVAC or medical devices where 700 kPa headroom is unnecessary. | Select when system max pressure ≤500 kPa - reduces sensitivity to overpressure transients and improves resolution at lower ranges. |
| MPXV7002DP | Differential configuration, 0–2 kPa range, I²C digital output, SOIC-8 package. | Requires microcontroller with I²C interface; suited for ultra-low-pressure applications like respiratory flow sensing. | Choose for digital integration and sub-100 Pa resolution - but requires firmware stack and lacks MPX5700GP's analog simplicity and high-voltage drive capability. |
Compared with MPX5500GP and MPXV7002DP, the MPX5700GP offers the widest gauge pressure range (0–700 kPa) in a drop-in analog format, making it optimal for industrial pneumatic and high-head HVAC systems where digital overhead or range limitation is unacceptable.

FAQ
What is the pressure port configuration of the MPX5700GP?
The MPX5700GP features a single pressure port on the "PORT #1 POSITIVE PRESSURE (P1)" side, as defined in Case 867B-04 mechanical drawings. This gauge configuration measures pressure relative to ambient atmosphere - P2 is open to air. The port side is identified by the physical port attachment, not marking or cap material.
Can the MPX5700GP operate from a 3.3 V supply?
No - the MPX5700GP is specified for 4.75–5.25 V operation only. At 3.3 V, output voltage falls outside its 0.2–4.7 V range, zero offset shifts beyond specification, and accuracy degrades beyond ±2.5%. Use MPXV5004GP (3.3 V ratiometric) instead for low-voltage systems.
What does "ratiometric" mean for the MPX5700GP output?
Ratiometric means the MPX5700GP output voltage scales linearly with its supply voltage (VS). For example, at VS = 5.0 V, full-scale output is ~4.7 V; at VS = 4.9 V, it is ~4.61 V. This allows using the same VS rail as the ADC reference voltage to cancel supply-induced errors - a key design advantage of the MPX5700GP.
Is the MPX5700GP compatible with non-air pressure media?
The MPX5700GP is qualified for dry air only. Fluorosilicone gel isolation may degrade with oils, solvents, or corrosive gases. Media compatibility must be validated separately - contact NXP for chemical resistance data sheets before deploying MPX5700GP with nitrogen, CO₂, or medical-grade gases.
How is the MPX5700GP calibrated during manufacturing?
The MPX5700GP undergoes full-scale temperature-compensated calibration at the wafer level and final test across 0–85°C. Offset, span, and TcOffset are trimmed using laser or EEPROM techniques, resulting in the documented ±2.5% VFSS accuracy without user calibration - a core value proposition of the MPX5700GP.
