MPX5700GS Présentation
An integrated pressure sensor (also called a board-mount pressure transducer or signal-conditioned pressure sensor) combines a MEMS piezoresistive sense element with a signal-conditioning ASIC in a single package. It sits in the measurement hierarchy: physical quantity (pressure) -> transducer (MEMS bridge) -> sensor (with conditioning) -> analog front end -> MCU/ADC. Integrated sensors simplify design by eliminating external amplifiers, temperature-compensation resistors, and calibration firmware.
Key features include 0.2 V to 4.7 V output (1.6% of VCC full scale at 5 V supply), ±2.5% accuracy over 0-85°C, gauge pressure measurement with single-port side access, and a typical response time of 1.0 ms. The MPX5700GS family uses piezoresistive silicon micromachining, where four strain-sensitive resistors form a Wheatstone bridge that produces a differential voltage proportional to applied pressure. NXP's on-chip ASIC amplifies, temperature-compensates, and calibrates the bridge output, eliminating the need for external components.
Typical applications include automotive engine control (MAP/Boost sensing), HVAC pressure monitoring, industrial process control, and medical respiratory equipment. The 0-700 kPa range covers manifold absolute pressure in gasoline and diesel engines as well as moderate hydraulic and pneumatic systems.
When designing with this device, decouple the VCC pin with a 100 nF ceramic capacitor placed within 5 mm of the IC pins. The output is ratiometric to VCC, so ADC readings should use the same 5 V rail as a reference for best accuracy. Avoid mechanical stress on the plastic port during PCB mounting.

Applications typiques
MPX5700GS convient pour 6 applications: Automotive Manifold Absolute Pressure (MAP) Sensing, Diesel Common-Rail Boost Pressure Monitoring, HVAC Refrigerant Line Pressure Monitoring, Medical Respiratory Pressure Monitoring, Industrial Pneumatic System Pressure Sensing, Hydraulic System Pressure Monitoring.
Automotive Manifold Absolute Pressure (MAP) Sensing
The MPX5700GS measures manifold pressure in gasoline and diesel engine control units (ECUs), directly informing air mass calculation for fuel injection and ignition timing. Its 0-700 kPa range covers naturally aspirated engines (~100 kPa at idle to atmospheric) plus turbocharged boost pressures up to 250 kPa gauge plus atmospheric. AEC-Q100 qualification and the 6-SIP axial port design survive under-hood thermal and vibration stresses. Output connects directly to the ECU ADC with the same 5 V rail as reference, enabling ratiometric cancellation of supply drift and ±2.5% accuracy from 0-85°C without external compensation.
Recommandé
Diesel Common-Rail Boost Pressure Monitoring
In diesel common-rail systems the MPX5700GS monitors turbocharger boost pressure to ensure proper injection timing and emissions compliance. The 0-700 kPa gauge range spans from atmospheric at idle to peak boost during wide-open throttle, while the 1.0 ms response time captures rapid boost transients during gear changes. The ratiometric 0.2-4.7 V output integrates directly with diesel control unit ADCs using the same 5 V reference rail, eliminating calibration drift over temperature. AEC-Q100 qualification and -40 to +125°C operation handle under-hood conditions.
Recommandé
HVAC Refrigerant Line Pressure Monitoring
The MPX5700GS monitors high-side refrigerant pressure in commercial HVAC systems to prevent compressor damage from overpressure conditions and to optimize expansion valve control. Its 0-700 kPa range covers R-410A high-side pressures (typically 1500-3000 kPa) when used in conjunction with a pressure divider or for low-side monitoring. The 1.0 ms response time tracks transient compressor cycling, and the analog output simplifies interface with legacy HVAC controllers without digital protocol overhead. The 6-SIP package with axial port simplifies tube-to-PCB integration.
Recommandé
Medical Respiratory Pressure Monitoring
In ventilators and CPAP/BiPAP machines the MPX5700GS measures patient airway pressure to ensure therapeutic delivery and detect mask leaks or circuit obstructions. The 0-700 kPa range accommodates typical airway pressures of 4-30 cmH2O plus circuit transients, while the ±2.5% accuracy is sufficient for pressure-limiting alarms. AEC-Q100 reliability and the ratiometric analog output simplify FDA submission documentation for medical devices. The through-hole 6-SIP package allows easy cleaning and sterilization of the sensor module.
Recommandé
Industrial Pneumatic System Pressure Sensing
Factory pneumatic systems operating at 0-10 bar (0-1000 kPa) use the MPX5700GS for pressure regulation, leak detection, and actuator feedback. The 0-700 kPa range covers most shop-air applications with margin for pressure spikes, and the 1.0 ms response time enables real-time closed-loop pressure control. The 6-SIP axial port simplifies direct coupling to standard pneumatic fittings via O-ring seal, while the analog output interfaces with PLC analog input modules without additional signal conditioning.
Recommandé
Hydraulic System Pressure Monitoring
Mobile and stationary hydraulic systems rely on the MPX5700GS to monitor load-sense, pilot pressure, and accumulator pre-charge pressure. Its 0-700 kPa range suits low-pressure hydraulic circuits, pilot lines, and brake pressure applications. The through-hole axial port allows direct mounting to hydraulic manifolds with O-ring sealing, and the ratiometric analog output drives PLC or controller ADC inputs directly. AEC-Q100 qualification and the wide -40 to +125°C operating range handle harsh mobile equipment environments.

Notes de conception
Decouple the VCC pin with a 100 nF ceramic capacitor placed within 5 mm of the IC pins. Add a 10 uF bulk capacitor on the 5 V rail near the sensor. The MPX5700GS draws approximately 5-8 mA from VCC, so the LDO must source at least 10 mA to maintain regulation. Avoid sharing the sensor's 5 V rail with high-current switching loads (relays, solenoids) - use a dedicated LDO branch to prevent ground bounce and supply noise from corrupting the ratiometric output.
Do not apply pressure beyond 1000 kPa (1.5x rated) or reverse polarity to VCC - both permanently damage the MEMS bridge. The axial port O-ring must seal properly to prevent leaks; test at 1.5x system pressure before deployment. Mechanical stress on the plastic port body during PCB mounting can shift calibration, so support the body with a bracket or potting compound in vibration-prone environments. The output is ratiometric to VCC - if VCC drifts, the pressure reading drifts proportionally.
Add an RC low-pass filter on the output pin to reduce noise - a 1 kohm resistor plus 100 nF capacitor gives a 1.6 kHz cutoff suitable for most HVAC and engine applications. For engine control with RPM sampling above 200 Hz, lower the cutoff proportionally. Keep analog output traces short and away from switching converter nodes. Use a guard ring or ground plane around the output trace to reject coupled noise from adjacent high-current traces.
