MPX5999D Обзор
An integrated silicon pressure sensor is a transducer that converts applied pressure into a proportional electrical signal. The MPX5999D belongs to the piezoresistive sensor family (X-ducer), a category that uses diffused strain gauges in a silicon diaphragm. In the broader taxonomy, the part is a MEMS sensor, then a board-mount pressure sensor, within the sensor hierarchy. The on-chip signal chain amplifies and calibrates the millivolt-level bridge output to a microcontroller-friendly 0.2-4.7 V rail-to-near-rail range, eliminating external analog components.
Key features include 5 V supply operation, differential pressure sensing at 1000 kPa full scale, factory calibration and temperature compensation across 0 to 85 C, typical accuracy of 2.5% (per NXP product page), a 6-SIP through-hole package, and a single-element patented X-ducer design. The output swing of 0.2 V to 4.7 V maps directly to a 0-1000 kPa differential pressure span, simplifying firmware translation.
The architecture combines a piezoresistive Wheatstone bridge on a micromachined silicon diaphragm with bipolar op-amp signal conditioning, thin-film laser-trimmed calibration resistors, and a bandgap reference. This produces a ratiometric, temperature-stable analog output that interfaces directly to a microcontroller ADC. The hermetic package isolates the die from harsh media when used with dry air.
Typical applications include industrial process control, HVAC pressure monitoring, manifold absolute pressure sensing, fluid level detection, and medical respiratory instruments. Designers also use it for barometric compensation, environmental sensing, and gas flow monitoring where calibrated analog output simplifies firmware.
When designing with the MPX5999D, add 100 nF and 1 uF decoupling near the VCC pin and keep the high-side and low-side pressure ports symmetric. The sensor is calibrated for dry air; contact the factory for media compatibility. Use the 0.2 V offset as the zero-pressure datum rather than 0 V.

Типичное применение
MPX5999D подходит для 6 применениеs: Industrial Process Control Pressure Monitoring, HVAC Duct Static Pressure Sensing, Medical Respiratory and Flow Instrumentation, Automotive Manifold Absolute Pressure Sensing, Liquid Level and Tank Monitoring Systems, Pneumatic and Compressed Air System Monitoring.
Industrial Process Control Pressure Monitoring
The MPX5999D's 0-1000 kPa differential pressure range and 5 V calibrated analog output make it ideal for industrial process control loops where supervisory controllers monitor hydraulic and pneumatic line pressure. At 1000 kPa full scale it covers most hydraulic pump discharge and accumulator pressures; the 0.2-4.7 V swing drives a 5 V ADC directly without signal conditioning. Its 2.5% accuracy and on-chip temperature compensation per the NXP datasheet eliminate drift in factory-floor ambient swings. Designers wire VCC through 100 nF decoupling, route VOUT into an instrumentation amp or MCU ADC, and apply a digital moving-average filter for pump pulsation noise. Unlike lower-pressure MPX5xxx parts the MPX5999D headroom allows direct regulator or valve inlet sensing without pressure dividers.

HVAC Duct Static Pressure Sensing
Building automation systems use the MPX5999D for HVAC duct static pressure, filter differential pressure, and VAV box airflow measurement. The 1000 kPa range comfortably covers duct static pressures (typically 0-1.5 kPa) and high-pressure fan inlet sensing on commercial AHUs. The 0.2-4.7 V calibrated analog output per the NXP datasheet feeds a BACnet or Modbus controller ADC without external amplification, and the 2.5% accuracy meets ASHRAE guideline 36 sensing tolerances. Designers connect the high port to atmosphere and low port to the duct reference; the ratiometric output allows firmware to compensate supply variation. Unlike board-mount digital sensors the MPX5999D's continuous analog output updates without I2C polling overhead.
Рекомендуется
Medical Respiratory and Flow Instrumentation
The MPX5999D serves medical respiratory devices including ventilator circuit pressure monitoring, CPAP flow sensing, and anesthesia machine breathing circuit verification. Its calibrated 0-1000 kPa differential range matches ventilator inspiratory pressure limits and circuit manometer readings; the 0.2-4.7 V swing interfaces directly to medical-grade MCU ADCs. Per the NXP datasheet the device is factory calibrated and tested for stability, important for patient-contact breathing circuits. Designers add bacterial/viral filters between the sensor ports and the patient circuit to protect the silicon die from contamination, and use dry air as the calibration medium per the datasheet warning. Unlike disposable pressure transducers the MPX5999D's calibrated on-chip compensation simplifies the medical device BOM.
Рекомендуется
Automotive Manifold Absolute Pressure Sensing
Although not AEC-Q100 qualified per the NXP product page, the MPX5999D can be used in non-safety automotive prototyping for engine manifold absolute pressure (MAP) and turbo boost sensing up to 1000 kPa. The wide pressure range covers naturally aspirated engines and moderate boost levels on small turbochargers. Its ratiometric 0.2-4.7 V output connects directly to engine ECU ADCs calibrated for NXP MPX sensors, and the 5 V supply matches automotive 5 V rails. Designers add ESD protection diodes and reverse-polarity TVS on VCC because the part lacks internal automotive-grade transient protection. Unlike MPX4100A absolute-pressure parts the MPX5999D requires a sealed reference port for MAP applications.

Liquid Level and Tank Monitoring Systems
The MPX5999D enables hydrostatic liquid level and tank pressure monitoring when referenced to atmosphere. With water column sensitivity of approximately 9.8 kPa per meter, the 1000 kPa range supports liquid columns up to 100 m, suitable for water storage tanks, fuel tanks, and chemical process vessels. The 0.2-4.7 V calibrated analog output per the NXP datasheet drives long cable runs back to a remote telemetry unit without digital noise pickup, and the on-chip temperature compensation handles outdoor ambient swings. Designers must verify media compatibility with the factory; the NXP datasheet specifies dry air as the calibration medium and warns against corrosive liquids in contact with the silicon die. Unlike ultrasonic level sensors the MPX5999D provides direct measurement unaffected by foam or vapor.
Рекомендуется
Pneumatic and Compressed Air System Monitoring
The MPX5999D is ideal for compressed air system monitoring including receiver tank pressure, filter differential pressure, and regulator output verification. Industrial pneumatic systems typically operate at 600-1000 kPa, which the MPX5999D covers directly at full scale. The 0.2-4.7 V calibrated analog output per the NXP datasheet interfaces directly to PLC analog input modules, and the on-chip signal conditioning eliminates the external instrumentation amp typically required for bridge-type pressure sensors. Designers mount the sensor on the tank wall with o-ring sealed port fittings, and add a snubber or restrictor to protect the die from pressure spikes during compressor cycling. Unlike mechanical pressure gauges the MPX5999D provides electronic data logging capability for predictive maintenance.

Заметки по проектированию
Power the MPX5999D from a regulated 5 V supply with 100 nF and 1 uF decoupling capacitors placed within 5 mm of the VCC pin per the NXP datasheet recommendation. The output is ratiometric with VCC, so any VCC variation directly scales the 0.2-4.7 V output span. For highest accuracy, use a low-noise LDO such as a TPS7A4701 SubMicro family part, or measure VCC via the MCU ADC and apply software ratiometric correction V(f) = V(out)/V(CC) * 5.0.
Keep the high-side (P1) and low-side (P2) pressure ports symmetric and use short, equal-length tubing runs to the sensor body. Asymmetric tubing lengths introduce common-mode errors that cancel imperfectly at higher differential pressures. Place the sensor away from heat sources - the NXP datasheet specifies the calibration temperature window, and thermal asymmetry across the die degrades accuracy. The exposed silicon die in the 6-SIP Module is sensitive to mechanical stress; do not apply side loads to the port stubs.
Per the NXP datasheet, the MPX5999D is calibrated using dry air as the pressure medium. Media other than dry air - including humid air, hydrocarbons, and corrosive gases - may alter accuracy and long-term reliability. Do not assume 0 V = 0 kPa; the offset is 0.2 V nominal. Also avoid exposing the sensor to overpressure above 1000 kPa - the X-ducer can permanently zero-drift if the full-scale pressure is exceeded by more than 2x.
