MPX2053GP 概要
A piezoresistive pressure sensor is a transducer that converts applied mechanical pressure into a proportional electrical signal by exploiting the piezoresistive effect of silicon. In the broader sensor taxonomy it belongs to MEMS pressure sensors, which sit alongside capacitive, optical, and resonant pressure sensing techniques. The MPX2053GP uses a Wheatstone-bridge configuration of implanted silicon resistors on a monolithic diaphragm; when pressure deflects the diaphragm, the bridge produces a differential millivolt output. The MPX2053GP is specifically designed for gauge (vented) pressure measurement referenced to atmospheric pressure through a side vent in the package.
Key features of the MPX2053GP include a full-scale range of 50 kPa (7.25 PSI), a sensitivity of 0.8 mV/kPa typical, an output span of 0 mV to 40 mV at 10 V supply, and on-chip temperature compensation across 0°C to 85°C. The device is calibrated and laser-trimmed at the factory, eliminating the need for external compensation networks in most applications. Maximum supply voltage is 16 V, and the device exhibits strong linearity across its operating range.
The MPX2053GP architecture consists of a silicon micromachined diaphragm with a piezoresistive Wheatstone bridge, signal-conditioned and laser-trimmed at the wafer level. The single radial port geometry simplifies plumbing and the through-hole 4-SIP package allows easy PCB integration. Internal compensation corrects for temperature-induced span and offset shifts typical of raw piezoresistive bridges.
Typical applications include HVAC pressure monitoring, medical respiratory equipment, process control, altimeters and barometers, and industrial pneumatic systems. Its low cost and calibrated output make it well suited for high-volume consumer and industrial designs requiring reliable gauge pressure measurement.
When designing with this device, ensure a clean, regulated 10 V supply for specified performance, and account for the millivolt-level output signal by using low-noise instrumentation amplifiers (such as INA128 or AD620) to boost the signal before ADC conversion. Proper port plumbing and protection from moisture ingress will extend operational life.

主な用途
MPX2053GP の用途: 6 件s: HVAC Duct Pressure Monitoring, Medical Respiratory Equipment, Process Control and Pneumatic Systems, Altimeters and Barometric Measurement, Automotive Manifold Pressure Reference, IoT and Smart Home Pressure Nodes.
HVAC Duct Pressure Monitoring
The MPX2053GP's 50 kPa full-scale range and 0.8 mV/kPa sensitivity make it ideal for HVAC duct static pressure measurement where typical operating pressures sit between 0 and 25 kPa. The on-chip temperature compensation across 0-85°C eliminates drift in unconditioned rooftop or basement installations. Plumbed into the duct via the 4.93 mm radial barbed port, the sensor delivers a ratiometric 0-40 mV signal at 10 V supply, which an instrumentation amplifier such as the INA128 boosts into a 0-5 V ADC input. Unlike capacitive differential pressure sensors, this piezoresistive solution offers lower cost and simpler single-sided mounting. Consider adding a snubber or particulate filter to protect the port from dust contamination in commercial building applications.

Medical Respiratory Equipment
In CPAP, BiPAP, and ventilator circuits, the MPX2053GP's 50 kPa range and 0.8 mV/kPa sensitivity provide sufficient resolution for breath-pressure waveforms between 4 and 20 cm H2O (0.4-2 kPa). The factory-calibrated and temperature-compensated output simplifies FDA-cleared device designs by removing the need for external linearization. The single radial port allows easy integration into patient tubing manifolds, and the through-hole 4-SIP package supports standard hand or wave soldering. For patient-side isolation, pair the sensor with an isolation amplifier such as the ISO124 between the Wheatstone output and the ADC. This approach delivers <0.5 cm H2O resolution with a 16-bit ADC, more than adequate for clinical respiratory monitoring.
おすすめ
Process Control and Pneumatic Systems
Industrial pneumatic systems operating from 0 to 50 kPa benefit from the MPX2053GP's calibrated linear output and ratiometric supply operation. In pick-and-place or robotic actuator monitoring, the sensor tracks regulator output pressure to detect leaks or stuck valves. The 10 V supply scales the 40 mV full-scale output predictably, making calibration straightforward across production units. The 4-SIP through-hole package withstands industrial vibration better than SMT alternatives, and the barbed port accepts standard pneumatic tubing directly. For 4-20 mA loop integration, drive the MPX2053GP output through an instrumentation amplifier and a current-loop transmitter such as XTR105 to deliver an industry-standard signal to PLC analog input modules.
おすすめ
Altimeters and Barometric Measurement
The MPX2053GP's 50 kPa range covers sea-level to approximately 5,500 m altitude, making it suitable for hiking altimeters, weather stations, and drone altitude hold. With 0.8 mV/kPa sensitivity and a Wheatstone-bridge output, the sensor delivers proportional readings when paired with a low-noise 24-bit ADC such as the ADS1220 for fine altitude resolution. On-chip temperature compensation reduces the cold-start drift typical of raw piezoresistive bridges, providing more accurate readings in outdoor temperature swings. For weather-grade barometric pressure, an external temperature sensor is recommended to apply second-order correction, but the built-in compensation handles the dominant span shift across 0-85°C.

Automotive Manifold Pressure Reference
Non-critical automotive applications such as cabin HVAC, fuel-tank pressure leak testing, or vacuum-assist monitoring can leverage the MPX2053GP's calibrated gauge-pressure output. The 50 kPa range fits cabin pressure differential and small vacuum measurements well. While this part is not AEC-Q100 qualified, its robust 4-SIP construction and -40 to 125°C storage tolerance support benign under-dash environments. Designers should add ESD protection diodes and a reverse-polarity guard on the supply pin for automotive use. For critical engine MAP sensing, NXP recommends the MPX4100A or MPX4115A which carry AEC-Q100 qualification.
おすすめ
IoT and Smart Home Pressure Nodes
IoT pressure nodes for leak detection, water-heater monitoring, or smart-appliance diagnostics benefit from the MPX2053GP's small form factor and calibrated output. While the 10 V supply exceeds typical 3.3 V IoT rails, a tiny boost converter such as the TPS61230 generates the required rail from a Li-ion cell. The 40 mV full-scale output requires a low-noise chopper amplifier before the ADC; the ADS1115 with its integrated PGA handles this in a single chip. Sleep current consumption is governed entirely by the external supply, making the MPX2053GP well suited to duty-cycled designs where the sensor is only powered during periodic measurements, extending battery life to multi-year operation in wireless leak detectors.

設計ノート
The MPX2053GP outputs a differential 0-40 mV signal at 10 V supply. Use a true instrumentation amplifier such as INA128 or AD620 with gain of 100-200 to bring the signal into the 0-5 V ADC input range. Keep amplifier input traces short and use shielded twisted-pair wiring to the bridge to reject common-mode noise. The output is ratiometric, so any supply ripple modulates the output directly - use a low-noise LDO such as the TPS7A4701 for the 10 V rail.
The MPX2053GP includes on-chip temperature compensation, but designers should still avoid mounting the sensor near heat sources such as power resistors, inductors, or processors. The 4-SIP package has minimal thermal mass; airflow across the device should be considered when used in enclosed enclosures. For environments with rapid temperature swings, add a small thermal mass (e.g., aluminum bracket) to dampen transients.
Never apply pressure exceeding 200 kPa to the MPX2053GP - the overpressure rating is 4x the full-scale range. Add a mechanical snubber or pressure-clamping orifice in pneumatic systems where water-hammer or valve-closure transients can spike above the rated range. Verify polarity of VS and GND before applying power; reverse polarity will damage the bridge. Do not block the gauge-port vent hole, as this turns a gauge sensor into an absolute sensor with shifted zero.
