MPXV2010DP - 10kPa Differential Pressure Sensor, 8-BSOP | STMicroelectronics
MPN: MPXV2010DP ✓ Hoạt độngMPXV2010DP Tóm tắt
A piezoresistive pressure sensor is a MEMS device whose Wheatstone-bridge strain gauges are diffused into a monolithic silicon diaphragm; flexure of the diaphragm under pressure unbalances the bridge and produces an output voltage directly proportional to the applied differential pressure. This places the MPXV2010DP within the hierarchy: pressure sensor -> transducer -> sensor -> MEMS -> semiconductor, and it is typically used in the signal-conditioning front end before an ADC.
Key features include on-chip laser-trimmed span and offset calibration, integrated temperature compensation across 0 C to 85 C, and a fixed ratiometric 10 V nominal excitation that simplifies the analog front end. The dual-port same-side inlet accepts pneumatic manifolds via 3.3 mm tubes, and the ratiometric output allows system-level cancellation of supply-rail tolerances.
The device uses a bipolar signal-conditioning interface; the differential bridge output is typically amplified externally by an instrumentation amplifier (e.g., a three-op-amp INA) before being digitized. Output impedance is approximately 1.7 kohm per side, so the amplifier input bias current must be kept low. Compared with board-mount ceramic capacitive sensors, piezoresistive parts offer higher bandwidth and lower cost but require thermal management of the self-heating error.
Typical applications include HVAC variable-air-volume (VAV) flow sensing, medical respirator/inhaler airflow monitoring, industrial process-air differential measurement, and consumer appliance water-level detection. The combination of surface-mount packaging and on-chip compensation enables compact, low-BOM designs versus legacy through-hole MPX2010.
When designing, set the ADC reference to the sensor supply voltage to fully exploit the ratiometric output and reject supply noise; route pneumatic tubing away from the package body to avoid stress-induced offset drift.

Ứng dụng tiêu biểu
MPXV2010DP phù hợp cho 6 Áp dụngs: HVAC Variable Air Volume (VAV) Flow Sensing, Medical Respirator / Inhaler Airflow Monitoring, Industrial Process-Air Differential Measurement, Consumer Appliance Water-Level Detection, Cleanroom and Lab Differential Pressure Monitoring, Drone Airspeed / Pitot-Static Probe.
HVAC Variable Air Volume (VAV) Flow Sensing
Why the MPXV2010DP fits HVAC VAV flow sensing: the sensor's 0-10 kPa differential range matches the typical 0-250 Pa velocity-pressure window commonly encountered across VAV boxes and duct spans when amplified and integrated, and the ratiometric 0-25 mV output scales with supply noise for first-order rejection. How it is used: the device is mounted in a pitot-static or laminar flow-element manifold; the pressure taps feed the two same-side ports, and a downstream INA amplifies the millivolt output before the building-automation ADC. A key benefit is that the surface-mount 8-BSOP package enables automated SMT assembly of high-volume VAV box electronics.

Medical Respirator / Inhaler Airflow Monitoring
Why the MPXV2010DP fits medical respirator and inhaler airflow monitoring: the 0-10 kPa differential range and 1.45 PSI full scale cover inspiratory and expiratory pressure drops measured at the patient wye or proximal flow sensor, and the on-chip temperature compensation across 0-85 C maintains span accuracy during warm humidified-gas operation. How it is used: the dual-port same-side inlet is plumbed into a flow restriction element (e.g., orifice plate), and a low-noise instrumentation amplifier (e.g., INA128) gains the 0-25 mV bridge output to the ADC's 0-5 V input range. The compact 8-BSOP package allows the sensor to be co-located with the flow path, reducing dead-space volume.

Industrial Process-Air Differential Measurement
Why the MPXV2010DP fits industrial process-air differential measurement: the 10 kPa differential range covers compressed-air line and clean-pneumatic-system pressure drops well below 1.5 PSI full scale, and the on-chip laser-trimmed calibration simplifies per-unit gain calibration during factory setup. How it is used: two 3.3 mm tubes tap high- and low-pressure points across an orifice or venturi in the pneumatic line, and the 0-25 mV output drives an isolation amplifier (e.g., ISO124) and 4-20 mA loop transmitter for plant-wide monitoring. The trade-off is that the part requires regulated 10 V excitation rather than a 3.3 V rail-rail interface.

Consumer Appliance Water-Level Detection
Why the MPXV2010DP fits consumer appliance water-level detection: the differential sensing principle can detect hydrostatic pressure head differences produced by changing water columns, and the 10 kPa full scale maps to roughly one meter of water - more than adequate for most washing-machine, dishwasher, and water-dispenser reservoirs. How it is used: a tube runs from the appliance sump into one port of the sensor while the other port vents to atmosphere, converting liquid height into a millivolt signal that an MCU ADC reads via a signal-conditioning op-amp. The SMT 8-BSOP package keeps assembly costs aligned with high-volume appliance manufacturing.

Cleanroom and Lab Differential Pressure Monitoring
Why the MPXV2010DP fits cleanroom and lab differential pressure monitoring: cleanroom pressurization is typically maintained within +/- 100 Pa across ventilation zones, well within the 10 kPa full-scale headroom that the differential sensor provides. How it is used: one port connects to the monitored room and the other to a reference space or ambient; an external low-noise amplifier feeds the 25 mV full-scale signal to a 16-bit ADC and the MCU computes particle-count-corrected airflow integrity. A benefit is on-chip temperature compensation avoids drift between 0 and 85 C lab ambient swings.

Drone Airspeed / Pitot-Static Probe
Why the MPXV2010DP fits drone airspeed sensing: the small differential pressure generated by a drone pitot-static probe (typically well below 1 kPa at cruise speeds under 10 m/s) falls within the sensor's highly sensitive 0-10 kPa band. How it is used: the same-side ports attach directly to forward-facing and side-facing pitot tubes, and the amplified 0-25 mV output drives the flight controller's ADC for airspeed-based pitch and throttle control. The compact surface-mount package keeps the air-data module lightweight, which matters for multirotor endurance.

Ghi chú thiết kế
The MPXV2010DP requires a regulated 10 V excitation to achieve the datasheet 25 mV full-scale output, per the STMicroelectronics datasheet. Many designs derive this from a low-noise 10 V LDO (e.g., LT3042) or a precision reference (e.g., MAX603) from a 12 V or 15 V rail; tying the ADC's reference input to the same 10 V makes the entire signal chain ratiometric. Estimated: at 5 mA bridge current, the 10 V LDO dissipates roughly 50 mW at the sensor - well within a SOT-23 footprint.
The 0-25 mV output of the MPXV2010DP is millivolt scale and easily corrupted by ground bounce, switching noise, and thermocouple effects. Use a low-noise instrumentation amplifier (e.g., INA128 or AD8421) with its REF pin driven by the same reference used for the sensor supply; keep bridge traces matched, guarded, and routed away from switching converters. Estimated: with a 1.7 kohm typical bridge impedance, amplifier bias current should be under 5 nA to keep offset error below 50 microvolt.
The on-chip temperature compensation covers 0 C to 85 C, per the datasheet; for outdoor or industrial environments spanning -40 C to +125 C, package-level drift and self-heating become non-negligible. Mount the sensor away from heat sources like power inductors and power resistors, and provide airflow over the 8-BSOP body. The thermal mass of the adjacent tubing mass also acts as a low-pass filter against rapid ambient-temperature swings.
Per the ST datasheet, the pneumatic ports protrude 3.3 mm from the same side of the 8-BSOP body and require PCB cutouts or front-panel access; the package outline is detailed in section 'Package Information'. Provide mechanical clearance at the port side of the PCB and avoid tall components in the port-shadow region. Seal the back of the sensor body to prevent leak paths that degrade common-mode pressure rejection.
Three frequent MPXV2010DP design pitfalls: (1) failing to make the ADC reference ratiometric to the 10 V supply - this loses the supply-noise rejection that the sensor is designed to provide; (2) measuring the differential output in single-ended mode and grounding Vout-, which halves the available signal and injects common-mode drift; (3) introducing long pneumatic tubes that act as restricted-flow RC filters and slow down the response time. Always use matched pneumatic tube lengths and condition the differential signal fully on-chip with a true INA.
