MPX5700DP 개요
A pressure sensor is a transducer that converts an applied pressure into a measurable electrical signal. In the system hierarchy, the MPX5700DP belongs to the MEMS pressure sensor family, which itself sits inside the broader sensor category and ultimately within the semiconductor product tree. Piezoresistive sensors like the MPX5700DP use the change in resistance of strain-implanted silicon resistors diffused into a diaphragm to detect the deflection caused by differential pressure, while integrated signal conditioning converts the millivolt-level bridge output into a ratiometric, ground-referenced analog voltage ready for an ADC input.
Key specifications include a 0 to 700 kPa operating range, an output swing of 0.2 V to 4.7 V at 5 V supply, a typical full-scale span of 4.5 V, accuracy of ±2.5% Vfss over 0 to 85°C, and a response time of 1 ms. The patented single-element transducer combines micromachining, thin-film metallization, and bipolar semiconductor processing. The 6-SIP module mounts vertically on a PCB and accepts dual 0.19" (4.93 mm) tubes for differential pressure measurement.
Typical applications include industrial process controls, HVAC fan/duct pressure monitoring, medical respiration equipment, level measurement in non-corrosive fluids, and any MCU/MPU-based system with an A/D input. The ratiometric analog output drives directly into a 5 V ADC without external amplification. The part is in production and supported by both NXP (the acquiring manufacturer) and STMicroelectronics, which second-sources the device.

일반적인 애플리케이션
MPX5700DP 적합 용도: 6 애플리케이션s: HVAC Duct Airflow Monitoring, Medical Respiratory Equipment, Industrial Process Control, Liquid Level Sensing (Non-Corrosive Fluids), Filter Clog Detection, Pneumatic System Monitoring.
HVAC Duct Airflow Monitoring
The MPX5700DP is well-suited for HVAC duct differential pressure measurement across fans, filters, and heat exchangers. Its 0 to 700 kPa range covers the pressure drops typical in commercial ductwork, while the 0.2 V to 4.7 V ratiometric output connects directly to a 5 V ADC in a building automation controller. The 1 ms response time tracks changing fan speeds without lag, and the integrated temperature compensation (calibrated over 0 to 85°C) maintains accuracy in conditioned-air plenums. Unlike bare bridge-type transducers, the on-chip signal conditioning eliminates the need for external op-amps or trim potentiometers.

Medical Respiratory Equipment
The MPX5700DP's calibrated analog output and dual-port differential sensing make it appropriate for medical devices such as CPAP/BiPAP machines, ventilator flow paths, and spirometer circuits. The 0.2 V to 4.7 V swing provides adequate resolution for breath-pressure profiles without an external instrumentation amplifier. Operating from -40°C to +125°C, the sensor tolerates sterilization environments, and the 6-SIP module's through-hole mounting resists vibration in portable devices. Pressure measurement is critical for patient safety in respiratory therapy, where the on-chip calibration reduces design risk and qualification time.
추천
Industrial Process Control
Industrial PLC and process-control systems use the MPX5700DP to monitor pump discharge, line pressure, and hydraulic system differential across filters. The 0 to 700 kPa span covers the operating range of many pneumatic actuators and low-pressure hydraulic circuits. The ratiometric 5 V output interfaces directly with industrial ADC front-ends, and the ±2.5% VFSS accuracy over 0 to 85°C provides reliable control-loop feedback. The 6-SIP through-hole package is rugged against vibration on factory floors and supports hand-soldered prototyping.
추천
Liquid Level Sensing (Non-Corrosive Fluids)
Differential pressure measurement enables hydrostatic liquid level sensing when one port of the MPX5700DP is connected to a sealed tank reference and the other to a submerged tap. With water or other non-corrosive fluids, the 700 kPa range covers tanks up to approximately 70 meters of head height. The calibrated analog output simplifies interface to MCU-based level indicators. Care must be taken to use compatible tubing and wetted materials - the standard port is suitable for air and water but not aggressive chemicals.
추천
Filter Clog Detection
The MPX5700DP excels at filter condition monitoring in compressed air systems, water filtration, and HVAC return-air paths. As a filter clogs, the differential pressure across it rises, and the 0.2 V to 4.7 V output maps directly to a clog-percentage indicator. The 1 ms response time tracks transient pressure spikes without averaging artifacts. Compared to mechanical pressure switches, this sensor provides a continuous analog signal for predictive maintenance algorithms in smart-factory systems.
추천
Pneumatic System Monitoring
Pneumatic controllers, actuators, and robotic end-effectors use the MPX5700DP for real-time line pressure feedback. With a 5 V supply drawn directly from the controller logic rail, the sensor integrates into compact pneumatic manifolds. The dual horizontal 0.19" tube ports accept standard pneumatic fittings, simplifying plumbing. The bipolar-signal-conditioned output eliminates external amplifiers, reducing BOM cost and PCB area in high-density valve banks.

설계 노트
The MPX5700DP draws its supply current directly from the 5 V rail; place a 100 nF ceramic decoupling capacitor as close to pins 3 and 4 (VCC) as possible, plus a 10 µF bulk capacitor on the rail to suppress switching-noise artifacts from upstream regulators. The output is ratiometric with VDD, so any noise or drift on the 5 V rail will appear as a corresponding offset/scale error on Vout. Use a low-noise LDO or a well-filtered switching regulator downstream for best accuracy.
Avoid connecting fluid or gas lines that contain corrosive media directly to the standard port - the wetted materials are compatible with dry air and non-aggressive fluids only. Also note that the output cannot drive large capacitive loads; keep the ADC sample-and-hold capacitance plus trace capacitance below ~1 nF or add a series resistor (1 kΩ) at Vout to isolate the output stage. Applying pressure beyond 700 kPa may permanently damage the diaphragm - install a mechanical pressure snubber or upstream regulator in over-pressure scenarios.
The 6-SIP module mounts vertically through the PCB; reserve a keep-out zone around the body for the dual 0.19" tubes and ensure the housing is mechanically supported to withstand tubing forces. Place ground-return stitching vias around the module footprint to minimize ground bounce on the analog output. If the application requires high immunity to EMI, route Vout on an inner layer with a continuous ground plane above and below, or shield the output trace.
