MPX2010D 概述
A piezoresistive pressure sensor is a transducer that converts applied gas or liquid differential pressure into a proportional electrical signal by exploiting the piezoresistive effect in doped silicon. Within the broader hierarchy, the MPX2010D is classified as a MEMS pressure sensor, then as a pressure transducer, then as a signal-conditioning sensor, and ultimately as an integrated semiconductor component. Compared to ceramic capacitive or strain-gauge bridge sensors, piezoresistive silicon sensors offer higher sensitivity in a smaller die, but require a stable excitation voltage and are typically limited to lower pressure ranges.
Key features include a 10 kPa full-scale pressure range with differential (Port 1 vs Port 2) measurement topology, 2.5 mV/kPa nominal sensitivity, 0.1% linearity over the compensated range, and an operating temperature range of 0C to +85C. The monolithic silicon diaphragm integrates the strain gauge and thin-film resistor network on-chip, while the uncompensated family cousin MPX2010GP (Case 344B-01) shares the same die but ships un-calibrated for cost-sensitive designs.
The MPX2010D uses a four-arm Wheatstone piezoresistive bridge diffused into a single silicon diaphragm. When pressure is applied across Ports 1 and 2, the diaphragm flexes and unbalances the bridge proportionally to the differential pressure. Laser trimming of on-chip resistors calibrates span and offset, and on-chip thin-film resistors implement first-order temperature compensation, removing the need for external compensation networks in most designs.
Typical applications include medical respiratory monitoring (spirometers, ventilators), HVAC airflow and differential pressure measurement, industrial process control, altimeters and barometric instrumentation, and portable blood-pressure cuffs. Designers select this part when a calibrated, temperature-compensated, low-pressure differential measurement is required without external signal conditioning.
When designing with the MPX2010D, provide a stable low-noise 10V excitation supply and a low-offset instrumentation amplifier such as the INA128 or AD620 to scale the 25 mV full-scale output to a usable 0-5V or 4-20 mA signal. Use anti-aliasing filtering between the sensor output and ADC, and isolate mechanical stress on the SIP package leads from the sensing ports to prevent PCB-induced offset drift.

典型应用
MPX2010D 适用于 6 应用s: Medical Respiratory / Spirometer, HVAC Airflow and Duct Pressure, Industrial Process Control, Portable Blood Pressure Cuffs, Altimeter and Barometric Instrumentation, Analytical and Lab Instrumentation.
Medical Respiratory / Spirometer
The MPX2010D's 0-10 kPa range and 2.5 mV/kPa sensitivity directly match the differential pressure drop across a Fleisch pneumotach tube used in spirometers and ventilators. With 0.1% linearity and on-chip temperature compensation over 0 C to +85 C, it provides reliable flow measurement across clinical ambient conditions. The small 4-SIP Case 344-15 module fits compact handheld designs, while the 25 mV full-scale output is easily amplified by an AD620 or INA128 instrumentation amp to a 0-5V ADC input. Unlike disposable flow sensors, the calibrated, temperature-compensated output eliminates external trim networks, reducing BOM cost and assembly time.
推荐
HVAC Airflow and Duct Pressure
The MPX2010D measures low differential pressure across HVAC ducts, VAV boxes, and filter monitoring stations in the 0-10 kPa range typical of building airflow. Its piezoresistive Wheatstone bridge outputs 0-25 mV at 10V excitation, easily scaled by an instrumentation amplifier to 0-10V for BMS controller input. On-chip laser trimming provides calibrated span and offset, while integrated temperature compensation over 0 C to +85 C handles unconditioned mechanical-room environments. Compared to capacitive differential pressure sensors, the MPX2010D offers higher sensitivity at a lower cost but requires careful PCB layout to avoid mechanical stress on the SIP leads.
推荐
Industrial Process Control
In industrial process control, the MPX2010D monitors low-pressure differential across flow elements, filter status indicators, and tank-level bubbler systems where 0-10 kPa spans the typical operating window. The 0.1% linearity and 2.5 mV/kPa sensitivity provide accurate closed-loop control feedback for valves and dampers. The 4-SIP Case 344-15 through-hole package withstands vibration in industrial enclosures better than surface-mount alternatives. Pair the sensor with a 16-bit ADC such as the MAX1302 for high-resolution monitoring, and use an isolated 4-20 mA loop driver like the XTR105 for long-cable plant installations.
推荐
Portable Blood Pressure Cuffs
The MPX2010D's 10 kPa full-scale range covers the 0-300 mmHg cuff pressure range used in home and clinical blood-pressure monitors. Its 2.5 mV/kPa sensitivity and 0.1% linearity deliver accurate systolic/diastolic measurement, while the calibrated temperature compensation over 0 C to +85 C handles body-temperature operation. The compact 4-SIP Case 344-15 housing fits inside handheld cuff pump assemblies, and the low 10V excitation requirement simplifies battery-powered designs. Compared to bulkier ceramic capacitive sensors, the silicon piezoresistive die enables slimmer wearables.
推荐
Altimeter and Barometric Instrumentation
The MPX2010D measures barometric pressure differentials in portable altimeters and weather instruments where 0-10 kPa spans the typical 1.45 PSI range. Its differential topology allows referencing against a sealed vacuum chamber for absolute altitude measurements. The 2.5 mV/kPa sensitivity produces a usable 25 mV full-scale signal that an instrumentation amplifier can scale to a 0-3.3V ADC input. On-chip temperature compensation keeps the altimeter accurate across cold-altitude to warm-ground transitions, and the 4-SIP package fits inside hand-held GPS units.
推荐
Analytical and Lab Instrumentation
In analytical instruments and laboratory equipment, the MPX2010D monitors low differential pressure across gas chromatograph flow restrictors, bioreactor headspace, and vacuum chamber leak-test fixtures. Its 0.1% linearity and 2.5 mV/kPa sensitivity support quantitative measurement, while the calibrated, temperature-compensated output simplifies lab-grade data acquisition. The 4-SIP Case 344-15 through-hole package is easy to swap during calibration cycles, and the 10V excitation requirement is met by standard lab power supplies. Use a low-noise LDO like the MAX8875 to drive the bridge from a single 12V rail for minimum drift.

设计说明
Drive the MPX2010D bridge with a stable, low-noise 10V excitation supply such as the MAX8875 LDO post-regulated from a 12V rail. Estimated: with a 10V bridge drawing ~6 mA, the sensor dissipates approximately 60 mW; use 0.1% tolerance supply regulation to keep full-scale output error below 0.5%. Add 100 nF ceramic bypass capacitors on the VCC pin to suppress switching-noise coupling from upstream DC-DC converters.
The MPX2010D's differential output is only 25 mV full-scale and is easily corrupted by PCB noise. Route the Vout+ and Vout- traces as a parallel differential pair with ground guard on both sides, and amplify immediately with an instrumentation amplifier such as the AD620 or INA128 placed within 25 mm of the sensor pins. Estimated: every 1 mV of coupled noise is 4% of full-scale error at 10 kPa. Add a 10 Hz to 1 kHz low-pass filter between the instrumentation amp output and the ADC to remove HVAC-induced pressure pulsation.
Mechanical stress on the MPX2010D's SIP leads causes PCB-induced offset drift of up to 1% full-scale. Mount the sensor with stress-relieved through-hole leads and avoid rigid mechanical coupling to the pressure ports. Estimated: 1 N of lead-bending force can shift offset by ~2 mV. Use a flexible silicone tube to connect ports and apply silicone conformal coating on the lead exit to dampen vibration in industrial environments.
Although the MPX2010D includes on-chip temperature compensation over 0 C to +85 C, the bridge excitation current generates self-heating that can drift output by up to 0.5% full-scale at maximum supply. Estimated: at 10V and 6 mA bridge current, internal die dissipation is 60 mW raising junction temperature ~5 C above ambient. For best stability in medical or precision lab applications, derate excitation to 8V or use pulsed excitation to minimize self-heating.
