MPXV2102GP - 100 kPa Gage Pressure Sensor | NXP
MPN： MPXV2102GP ⚠ 最後購買機會MPXV2102GP 概覽
What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a MEMS device in which four silicon strain gauges arranged in a Wheatstone bridge on a flexible diaphragm change resistance proportionally to applied pressure. Pressure sensors belong to the sensor transducer hierarchy: pressure sensor -> force/pressure transducer -> MEMS sensor -> semiconductor sensor. The MPXV2102GP is part of the NXP MPX2102 series, which adds on-chip thin-film resistor laser trimming for span, offset, and temperature compensation, yielding a near-linear voltage output that requires only an instrumentation amplifier downstream.
Key features include a pressure range of 0 kPa to 100 kPa (0-14.5 PSI), a typical full-scale output of 40 mV at 10 V excitation, a sensitivity of approximately 0.4 mV/kPa, an operating temperature range of -40 °C to +125 °C, and a typical differential input resistance of 400 Ω. The single-element monolithic diaphragm topology simplifies PCB assembly because the side port accepts a 0.13" (3.17 mm) tube directly without manifold hardware, while the 8-SMD gull-wing footprint supports standard SMT reflow. Per the manufacturer datasheet, the device is factory-trimmed to within ±0.25% of span at 25 °C.
Typical applications include medical patient monitoring (blood pressure cuffs, ventilators, infusion pumps), industrial pneumatics, HVAC air-flow monitoring, altimeters, barometers, process control, and automotive manifold absolute pressure sensing. Because the device outputs millivolts, a low-offset op-amp such as the INA128 or AD620 is typically used in a follow-up gain block to bring the signal into the 0-5 V ADC input range.
When designing with this part, observe that the 10 V excitation must be low-impedance (the bridge draws ~6 mA at 10 V), input protection diodes are absent, and the side port must be connected with a leak-free tube fitting to maintain accuracy.

典型應用
MPXV2102GP 適用於 6 應用s: Medical Blood Pressure Monitoring, HVAC Air-Flow and Duct Pressure Sensing, Industrial Pneumatic System Monitoring, Automotive Manifold Absolute Pressure Sensing (Reference Design), Barometric Altitude Measurement (Reference Design), Process Control and Industrial Instrumentation.
Medical Blood Pressure Monitoring
The MPXV2102GP's 0-100 kPa range covers the full clinical cuff-pressure spectrum (0-300 mmHg cuff inflation) and its 0.4 mV/kPa sensitivity delivers a clean ~40 mV signal that an INA128 instrumentation amplifier can scale to the 0-5 V ADC input range of a portable patient monitor. The on-chip thin-film laser trim holds ±0.25 % linearity across the 0-100 kPa span, eliminating the need for software linearization in firmware. The 3.17 mm side port mates directly with standard medical silicone tubing, simplifying cuff harness design and reducing leak paths.
推薦
HVAC Air-Flow and Duct Pressure Sensing
Building-automation duct static-pressure probes typically operate at 0-2.5 kPa but the MPXV2102GP's 0-100 kPa range also covers higher-pressure drop coils and filter-status switches when scaled by the downstream amplifier. The vented-gauge configuration references ambient barometric pressure automatically, so altitude corrections are not required for indoor installations. The 8-SOP SMT footprint supports high-density HVAC controller boards and the -40 °C to +125 °C operating range covers rooftop and plant-room environments without additional thermal management.
推薦
Industrial Pneumatic System Monitoring
Factory pneumatic lines commonly operate at 0-100 kPa for low-pressure solenoid valves and air-bearing supply, exactly the MPXV2102GP calibration range. The 40 mV full-scale output at 10 V excitation provides enough headroom to feed a 16-bit ADC directly after a low-noise x100 gain stage, supporting sub-100 Pa pressure-resolution measurements for leak-detection algorithms. The side-port vertical tube orientation accepts standard 3.17 mm push-to-connect fittings used in pneumatic manifolds, eliminating adapters that could introduce leak points or dead volume.
推薦
Automotive Manifold Absolute Pressure Sensing (Reference Design)
Although NXP has discontinued the MPXV2102GP for new automotive designs, the part remains in service in legacy MAP sensor reference designs that sense manifold vacuum 0-100 kPa (gauge referenced to barometric through the vent port). The 10 V excitation rail is readily available from 12 V vehicle buses via a low-dropout regulator, and the 0.4 mV/kPa sensitivity matches the resolution required for ECU fuel-mapping algorithms. New designs should use the NXP MPX5050 or MP3V5000 series which integrate on-chip signal conditioning.
推薦
Barometric Altitude Measurement (Reference Design)
With the vented-gauge side port exposed to ambient atmosphere, the MPXV2102GP measures barometric pressure 0-100 kPa (corresponding to sea level down to roughly sea-level +200 m for full-scale use). Combined with temperature compensation (already on-chip via thin-film trim), a system designer can derive altitude to within ±10 m using the standard barometric formula. The SOP-8 footprint enables compact handheld altimeter/barometer designs where PCB real-estate is constrained.
推薦
Process Control and Industrial Instrumentation
Process-control loops often require front-end pressure transducers that can be calibrated against a stable 10 V excitation rail, exactly the use case for the MPXV2102GP. The 40 mV full-scale output can be scaled by an x125 amplifier to a standard 0-5 V industrial signal, supporting 4-20 mA loop converter boards via a XTR105 or XTR106 current-loop transmitter. The -40 °C to +125 °C operating range covers most plant environments without additional thermal protection.

主要差異化特點

- Drop-in compatible with MPX2102GP (same die, different lead form) (對比MPX2102GP)
- Exact 100 kPa range match with cross-brand XGZP193 third-party alternative (對比XGZP193)
設計說明
The MPXV2102GP outputs only ~40 mV full-scale at 10 V excitation, so a low-noise instrumentation amplifier (INA128, AD620) with at least 100× gain is required to bring the signal into the 0-5 V ADC input range. Estimated: a 100× gain stage with 5 µV/°C input-offset drift contributes ~0.5 µV/°C referred to the sensor output, well below the 0.4 mV/kPa sensitivity. Use a dedicated low-noise 10 V LDO (TPS7A4700) rather than sharing the digital supply to avoid digital switching noise coupling into the bridge.
The MPXV2102GP requires a low-impedance 10 V source because the bridge draws ~6 mA (input resistance 400 Ω); a high-impedance source (e.g., 12 V rail through a 33 kΩ resistor) will cause large excitation errors and self-heating. Do not exceed 12 V excitation — the strain-gauge network is not protected against over-voltage. The vented-gauge port must be connected with a leak-free tube fitting; even a small leak will cause barometric-pressure aliasing in the reading.
Keep analog ground returns from the bridge separate from digital ground returns until they join at the ADC ground pin (star-ground topology). The 8-SOP case 1735 package thermal pad is internally tied to the die substrate, so it can be soldered to the analog ground plane. Place the 100 nF bridge-decoupling capacitor as close to pin 1 (VS+) as possible to filter switching noise from the 10 V rail.
