MPX5010GSX - 10kPa Integrated Pressure Sensor 6-SIP | NXP
MPN： MPX5010GSX ✓ 啟用中MPX5010GSX 概覽
What is an integrated silicon pressure sensor? An integrated silicon pressure sensor is a MEMS device that converts applied pressure into an electrical output on a single silicon die, integrating the mechanical sensing element (typically a piezoresistive bridge etched into a silicon membrane) with active signal-conditioning electronics. These sensors sit in the broader hierarchy of pressure transducers -> MEMS sensors -> sensors -> electronic components. Compared to bare piezoresistive cells, integrated parts eliminate the need for external op-amp gain stages, temperature compensation and offset trim circuits, simplifying MCU-based designs.
Key features of the MPX5010GSX include a 4.5 V to 5.5 V supply range, 0.2 V to 4.7 V ratiometric output spanning the full calibrated range, 1.0 % typical accuracy and a response time under 2 ms. The device is factory calibrated, RoHS compliant and qualified for automotive and industrial HVAC/medical instrumentation. Its vented gauge configuration references the back side of the diaphragm to ambient, simplifying board-level mounting and hose connections.
Technically, the MPX5010GSX exploits a single-axis X-flow port geometry: media enters the side tube, presses on the topside of the diaphragm, while the underside of the die is exposed through a vent hole to local atmospheric pressure. The on-chip ASIC supplies a 1.0 mA excitation to the bridge, conditions the differential signal with chopper-stabilized gain stages and drives a low-impedance ratiometric output that scales with VCC, allowing ADC measurements to compensate for supply variation.
Typical applications include HVAC blower and duct pressure sensing, blood pressure monitors, respirators and ventilators, level and flow instrumentation, appliance pressure feedback and process-control analog front ends. The 5 V single-supply operation and standard 0.2 V to 4.7 V output span map directly to most MCU ADC input ranges.
When designing with the MPX5010GSX, place a 0.1 uF decoupling capacitor close to the supply pin, keep the vent port clear of obstructions and protect the side tube from liquid ingress with an inline hydrophobic filter when measuring humid media. Account for the 5 ms settling time when designing sample-and-hold windows for slow-moving control loops.

典型應用
MPX5010GSX 適用於 6 應用s: HVAC Duct Pressure Sensing, Blood Pressure Monitor Front End, Respirator and Ventilator Pressure Feedback, Appliance Pressure Feedback, Process Control Analog Front End, Level and Flow Instrumentation.
HVAC Duct Pressure Sensing
The MPX5010GSX's 0 to 10 kPa range and vented gauge topology map directly to HVAC duct static-pressure measurements used for VAV (variable air volume) damper feedback and filter-load monitoring. With 0.2 V to 4.7 V output at 5 V supply the sensor connects to any standard MCU ADC without level shifting, and the on-chip ASIC eliminates the discrete bridge-excitation and temperature-trim circuit that raw piezoresistive cells require. Compared to differential alternatives such as the MPX5010DP, the vented gauge version references ambient through the rear vent, so no second hose run to outside air is needed. A 0.1 uF decoupling capacitor close to the supply rail and a hose barb coupling to the duct complete the typical analog front end.

Blood Pressure Monitor Front End
Medical blood-pressure cuffs operate in the 0 to 300 mmHg range, well within the 10 kPa (75 mmHg max) of the MPX5010GSX, making the sensor a fit for low-pressure medical monitoring where cuff pressure directly correlates to systolic and diastolic readings. The on-chip integrated ASIC signal conditioning provides the low-drift, low-noise output required for accurate sphygmomanometer algorithms, and the factory calibration removes the manual trim step that bare piezoresistive cells demand. Unlike a bare cell the integrated sensor outputs a calibrated 0.2 V to 4.7 V span that drives an op-amp input directly, simplifying patient-isolated analog front ends.
推薦
Respirator and Ventilator Pressure Feedback
Respirator and ventilator circuits use the MPX5010GSX to sense inspiratory and expiratory line pressure for closed-loop control and patient-monitoring alarms. The 0 to 10 kPa range covers the working pressure of non-invasive CPAP/BiPAP machines and low-pressure anesthesia circuits, while the 0 C to 85 C operating range accommodates warmed breathing-gas environments. The vented gauge configuration simplifies patient-circuit integration by referencing ambient pressure, eliminating the second hose run that differential sensors require.
推薦
Appliance Pressure Feedback
Washing machines, dishwashers and water-level monitors use the MPX5010GSX to sense water-level height, pump differential pressure or spray-arm feedback in the 0 to 10 kPa range. The integrated pressure sensor's vented gauge topology references ambient pressure through the rear vent, so the board does not need a second vent hose, simplifying assembly inside sealed appliance enclosures. The on-chip ASIC's temperature compensation ensures consistent readings across the 0 C to 85 C appliance operating range, including cold-fill wash cycles and hot-sanitize rinse cycles.
推薦
Process Control Analog Front End
Industrial process-control boards use the MPX5010GSX as a calibrated analog front end that converts low-pressure process variables (tank level, filter loading, cleanroom pressure) into a 0.2 V to 4.7 V signal for PLC analog modules or isolated 4-20 mA transmitters. The factory-trimmed accuracy of 1.0 % typical removes the need for manual calibration potentiometers and the on-chip ASIC handles the bridge excitation, gain and temperature compensation that a discrete piezoresistive cell would otherwise require. The 6-SIP through-hole package accepts standard PCB headers, simplifying field replacement.
推薦
Level and Flow Instrumentation
Low-cost liquid-level and gas-flow instruments use the MPX5010GSX to sense hydrostatic head in small tanks or pressure drop across an orifice in laminar flow elements. The integrated sensor's 10 kPa range covers column heights up to 1 m of water and the differential pressure generated by small-orifice flow restrictors, while the on-chip signal conditioning eliminates the discrete instrumentation amplifier that bare cells need. Compared to bare piezoresistive cells the MPX5010GSX integrates bridge excitation and temperature compensation, reducing BOM count by 6 to 8 components per measurement channel.

設計說明
Place a 0.1 uF decoupling capacitor as close as possible to the VCC pin (pin 1) of the MPX5010GSX, with the ground return directly to the GND pin (pin 3) to minimize supply-induced noise on the analog output. Keep digital traces (MCU, switching regulators) routed away from the sensor output trace to prevent coupling of switching transients into the low-level 0.2 V output region.
Do not obstruct the rear vent hole of the MPX5010GSX - the vented gauge topology references atmospheric pressure through this opening. Seal the vent with waterproof membranes that block liquid water but allow air pressure equalization, otherwise the sensor will drift or report incorrect gauge pressure. For humid or condensing environments, add an inline hydrophobic filter on the side-port tube and a Gore-Tex vent membrane over the rear vent.
Mount the MPX5010GSX with the side-port tube oriented vertically and the vent hole facing downward to prevent dust ingress and condensate accumulation. Allow at least 3 mm clearance around the port for hose-coupling access and stress relief. Avoid mounting the sensor near heat sources (power resistors, inductors) that could introduce thermal gradients across the package and shift the calibrated output.
