MPXV5010GC6U 概述
A pressure sensor is a transducer that converts an applied pressure into a measurable electrical signal; piezoresistive sensors use diffused strain gauges on a silicon diaphragm whose resistance changes with mechanical strain. The MPXV5010GC6U combines micromachined silicon, thin-film metallization, and bipolar signal conditioning to provide a temperature-compensated, calibrated, high-level analog output that interfaces directly to an MCU/MPU A/D input without external amplification.
Key features include on-chip signal conditioning and temperature compensation, a high-level 0.2 V to 4.7 V ratiometric output that aligns with a 5 V ADC full-scale, a vented-gauge reference that compensates for ambient barometric pressure, and a top-port male tube inlet sized at 0.13 inch (3.17 mm) for hose or barb connections. The integrated design eliminates external compensation components, simplifying BOM and PCB area.
Architecturally the device uses a diffused piezoresistive bridge on a micromachined silicon diaphragm; the bridge is excited by the supply and the differential output is amplified and offset by on-chip bipolar circuitry to produce a near-ground-referenced, rail-ratiometric transfer function. This architecture delivers factory-calibrated accuracy over the specified pressure range without user trimming.
Typical applications include medical respiratory monitoring (spirometers, ventilators), HVAC variable-air-volume (VAV) controls, gas flow sensing, industrial process monitoring, and consumer airflow measurement. The wide 0 to 10 kPa range with 1.45 PSI full-scale suits both human-breath pressure monitoring and low-pressure industrial gas lines.
When designing with this part, observe the 4.75 V to 5.25 V supply window to preserve ratiometric output accuracy, place a 100 nF decoupling capacitor close to the supply pin, and account for the vented-gauge reference in altitude-sensitive applications. The tube inlet orientation (top port) constrains PCB placement relative to the air path.

典型应用
MPXV5010GC6U 适用于 6 应用s: Medical Respiratory Monitoring, HVAC Variable-Air-Volume (VAV) Control, Gas Flow Sensing, Industrial Process Monitoring, Consumer Airflow and Air-Quality Devices, Pneumatic Leak Test Fixtures.
Medical Respiratory Monitoring
The MPXV5010GC6U's 0 to 10 kPa range and on-chip temperature compensation make it a strong fit for spirometers, ventilators, and CPAP airflow channels where breath pressure spans roughly -1 to +10 kPa. Its ratiometric 0.2 V to 4.7 V output on a 5 V rail couples directly to a medical-grade MCU ADC without instrumentation amplifiers, reducing BOM and leak paths. The vented-gauge reference rejects ambient barometric drift so readings stay consistent across altitude and weather.
推荐
HVAC Variable-Air-Volume (VAV) Control
Building automation ducts typically run at static pressures from 0 to 10 kPa, exactly the range of the MPXV5010GC6U. Its top-port tube inlet accepts standard 3.17 mm hose barbs used in VAV boxes, and the calibrated analog output feeds the damper controller ADC without gain stages. The on-chip temperature compensation keeps accuracy across supply-air temperature swings common in rooftop AHUs.
推荐
Gas Flow Sensing
Differential pressure across an orifice or laminar flow element is the standard method for infering gas flow, and the 0 to 10 kPa window covers most low-flow medical and industrial gas lines. The MPXV5010GC6U provides a calibrated, ratiometric output that pairs with a differential pair or a single-ended reference for flow calculation. NXP's MPXV5010GC6 product page positions this part family for gas flow instrumentation specifically.
推荐
Industrial Process Monitoring
Low-pressure process lines such as cleanroom underpressure, vacuum-pump backing lines, and pneumatic leak-test fixtures sit comfortably within 0 to 10 kPa. The MPXV5010GC6U's SOP-8 surface-mount package supports high-density instrumentation boards, while its calibrated output eliminates the per-unit trim step typical of bare piezoresistive bridges. On-chip temperature compensation keeps readings stable across process-side temperature excursions.
推荐
Consumer Airflow and Air-Quality Devices
Smart-home air-quality monitors, range-hood airflow sensors, and HVAC zone controllers need a compact, low-cost pressure element that runs from a 5 V rail. The MPXV5010GC6U integrates signal conditioning and temperature compensation, eliminating the analog front-end that would otherwise inflate BOM and PCB area. The ratiometric output simplifies ratiometric ADC reads, improving effective resolution.
推荐
Pneumatic Leak Test Fixtures
Leak-test fixtures pressurize a sealed assembly and watch for decay; the 0 to 10 kPa range of the MPXV5010GC6U covers most consumer and industrial leak-test envelopes. Its vented-gauge reference subtracts ambient pressure so the test reading reflects only the fixture's internal pressure. The factory-calibrated accuracy avoids per-fixture gain trim and supports multi-channel test heads.

设计说明
Operate the MPXV5010GC6U strictly within 4.75 V to 5.25 V to preserve ratiometric accuracy; the 0.2 V to 4.7 V output scales with VDD, so a 4.85 V supply shifts the full-scale output down proportionally. Place a 100 nF X7R ceramic decoupling capacitor within 2 mm of pin 1 (VDD) and a 10 uF bulk capacitor on the supply rail to suppress noise that would otherwise couple into the analog output.
The top-port tube inlet occupies the top face of the SOP-8 body and requires PCB keep-out above the sensor for hose or barb mating; orient the long axis of the package away from tall components. Avoid routing digital traces beneath the sensor body, as the vented-gauge reference port is on the underside and digital switching noise can couple through the silicon die.
Route the analog output trace as a guarded microstrip with a continuous ground plane on either side, keep the trace under 50 mm, and add a small RC low-pass filter (10 kohm + 100 nF) close to the ADC input if the MCU is shared with switching power or digital I/O. The factory calibration assumes a high-impedance ADC input, so verify the ADC sample-and-hold settling time is well below 1 ms.
Do not pot, conformal-coat, or pot the top-port inlet; clogging or sealing the tube inlet will cause drift or failure. Avoid silicone-based conformal coatings that outgas and contaminate the inlet. For washable assemblies, use a Parylene coating compatible with piezoresistive sensors per NXP's application notes.
