MPX5500DP Übersicht
A piezoresistive pressure sensor is a transducer that converts applied pressure into a proportional electrical signal by exploiting the piezoresistive effect in doped silicon. The MPX5500DP belongs to the broader hierarchy of pressure transducers -> MEMS sensors -> sensors -> semiconductors. It combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing to integrate the sensing element and signal-conditioning circuitry on a single die.
Key features include 500 kPa full-scale differential range, ratiometric 5 V supply, 0.2 V to 4.7 V output swing, ±2.5 %FS typical accuracy, and on-chip temperature compensation. The dual-port (DP) housing routes pressure through two opposing tube ports, enabling gauge-differential measurements where one side serves as the reference. The 6-SIP package measures approximately 17.78 mm x 29.48 mm x 10.67 mm with a 2.54 mm lead pitch.
The on-chip signal conditioning includes a precision bandgap reference, temperature-compensation network, and a calibration network that trims offset and full-scale span at the factory. The analog output is ratiometric to the supply voltage, so when used with a 5 V ADC reference tied to VCC, gain errors from supply variation are largely cancelled. Designers connect the output directly to a microcontroller ADC input without external op-amps.
Typical applications include industrial process control, HVAC blower monitoring, respiratory/inhalation equipment, level measurement, and engine control. The dual-port configuration is particularly useful for measuring pressure drop across flow elements (restricts) such as orifice plates in fluid systems, or for differential pressure across filters and pumps.
When designing with this device, decouple the supply pin with a 100 nF ceramic capacitor placed close to the device. Because the output is ratiometric, route the 5 V supply that powers the sensor as the ADC reference voltage to cancel VCC drift. Avoid placing the device near heat sources; the temperature-compensation network is calibrated for the device's self-heating profile.

Typische Anwendungen
MPX5500DP ist geeignet für 7 Anwendungs: Industrial Process Control, HVAC Blower & Filter Monitoring, Medical Respiratory Equipment, Liquid Level Measurement, Engine Control & Manifold Pressure, Pump & Compressor Monitoring, Pneumatic System Leak Testing.
Industrial Process Control
The MPX5500DP's 500 kPa (72.52 PSI) differential range and ratiometric 0.2-4.7 V output make it well-suited to industrial process control loops where a microcontroller ADC reads line pressure directly. The on-chip temperature compensation over 0-85 C cancels ambient drift on the factory floor, while the dual-port package measures pressure drop across pumps, filters, and valves without external signal conditioning. Connected to a 5 V MCU with the ADC reference tied to the sensor supply, the ratiometric output cancels VCC drift and yields stable closed-loop control.
Empfohlen
HVAC Blower & Filter Monitoring
HVAC blower and filter monitoring benefits from the MPX5500DP's 6-SIP module with dual horizontal ports, allowing differential measurement across a filter or fan. Although the MPX5010DP is preferred for low-pressure (<10 kPa) HVAC drops, the MPX5500DP handles higher-pressure duct work and pre-filter measurement where drop can reach hundreds of kPa. The ratiometric analog output feeds a 0-5 V ADC input on the building controller, and the through-hole SIP package survives the temperature swings of mechanical equipment rooms.
Empfohlen
Medical Respiratory Equipment
Medical respiratory and inhalation equipment requires a clean differential pressure reading with low drift and on-board calibration. The MPX5500DP delivers factory-calibrated, temperature-compensated output across 0-85 C, suitable for ventilator line-pressure sensing and oxygen-blender monitoring within its 500 kPa envelope. The bipolar-processed silicon die provides long-term stability required by medical devices, and the ratiometric interface simplifies medical-safety isolation barrier design because the sensor and ADC reference share the same isolated supply.
Empfohlen
Liquid Level Measurement
Liquid level measurement via hydrostatic pressure at the bottom of a tank uses the MPX5500DP's differential sensing capability, where one port connects to the liquid head and the other vents to atmosphere. The 500 kPa range covers tanks up to roughly 51 meters of water column, while the on-chip signal conditioning avoids external op-amp circuitry that would otherwise need to be sealed from the wet side. The 6-SIP package mounts on a PCB inside the instrument head, far from the wetted media.
Empfohlen
Engine Control & Manifold Pressure
Engine control and manifold absolute pressure (MAP) sensing for small engines, pneumatic actuators, and compressors benefits from the MPX5500DP's 500 kPa span and on-chip temperature compensation. The dual-port differential configuration can be re-purposed as a gauge measurement by venting one side, providing flexibility across engine platforms. The robust through-hole SIP package resists vibration and thermal cycling in engine bay environments better than surface-mount MEMS sensors.
Empfohlen
Pump & Compressor Monitoring
Pump and compressor monitoring uses the MPX5500DP's 6-SIP dual-port package to sense differential pressure across the pump inlet and outlet, providing flow and blockage diagnostics. The 0.2-4.7 V ratiometric output feeds directly into a 5 V MCU ADC, eliminating external instrumentation amplifiers, while the on-chip temperature compensation keeps accuracy stable across the device's self-heating profile. The 500 kPa full-scale covers most industrial pneumatic pump heads and small hydraulic applications.
Empfohlen
Pneumatic System Leak Testing
Pneumatic system leak testing requires a sensitive differential pressure measurement that the MPX5500DP delivers with its 500 kPa full-scale and on-chip temperature compensation. The dual-port package isolates test pressure from reference pressure, and the ratiometric output lets a microcontroller log decay rates over time without external ADC references. The 6-SIP module handles through-hole mounting in industrial test fixtures where vibration and mechanical stress rule out smaller SMD packages.

Wichtigste Unterscheidungsmerkmale
- Dual-port differential sensing in a single 6-SIP package (vs. MPX5500D)
- Higher 500 kPa full-scale range versus MPX5010DP family (vs. MPX5010DP)
- Lower full-scale for better resolution at moderate pressures (vs. MPX5700DP)
- On-chip temperature compensation factory-calibrated 0-85 C (vs. Discrete pressure sensor modules)
Designhinweise
Decouple the VCC pins (1 and 6) with a 100 nF ceramic capacitor placed within 5 mm of the package leads. The MPX5500DP output is ratiometric to VCC, so route the 5 V sensor supply as the ADC reference voltage - this cancels supply drift and is the key design rule for accurate pressure readings. Twisted-pair or shielded cabling is recommended if the sensor is more than 50 mm from the MCU.
Mount the MPX5500DP such that the dual tube ports face the pressure manifold with short, stiff tubing to minimize resonance in dynamic pressure measurements. Avoid mounting heat sources (power resistors, regulators, inductors) within 10 mm of the device body because the temperature-compensation network is calibrated for the device's self-heating profile. Use a star-ground topology at the sensor GND pin to avoid ground-bounce errors.
Do not apply pressure exceeding the 500 kPa full-scale rating or the die may be permanently damaged. Do not connect VCC to a non-ratiometric supply unless the ADC reference is also that same supply - the 0.2-4.7 V output assumes 5 V nominal. Do not apply reverse pressure (vacuum on the high port) beyond what the datasheet specifies; consult the manufacturer datasheet for negative-port pressure limits before using the device in a vacuum-side configuration.
Estimated: at a 5 V supply and 500 kPa full scale, the output sensitivity is roughly 9 mV/kPa. With a typical 10-bit ADC (4.88 mV/LSB), resolution is about 0.5 kPa per LSB - adequate for industrial process monitoring but marginal for low-pressure HVAC; choose a 12-bit ADC for finer resolution. Add a 100 ohm series resistor and 10 nF cap on the VOUT pin if long cables are used to filter EMI.
