MPXV2102DP Descripción general
A piezoresistive pressure sensor is a MEMS device that converts applied pressure into a small differential voltage by changing the resistance of strain-sensitive silicon resistors diffused into a diaphragm. NXP's MPX series adds on-chip temperature compensation and laser-trimmed calibration, so the output remains linear and stable across the full operating range without external trimming. In the broader hierarchy, this places the MPXV2102DP as a board-mount pressure transducer (sensor -> transducer -> sensor) -> MEMS pressure sensor -> signal-conditioning IC family. The 'V' in MPXV2102DP indicates the dual-port BSOP package variant, distinct from the single-port 'G' and 'GP' variants in the family.
Key features include 0 mV to 40 mV full-scale span at 10 V excitation, differential sensing with two side-by-side ports for gauge-reference applications, integrated temperature compensation from 0 C to 85 C, and ratiometric output that scales with supply voltage. The 8-BSOP package has vertical port orientation for through-hole-style pressure attachment, making it suitable for manifolds and enclosures where tubing enters from one direction.
The architecture combines a silicon strain gauge bridge with a thin-film resistor network that cancels temperature-induced span and offset drift. The output impedance is nominally 1.1 kohm and the bridge is designed for 10 V typical excitation (max 16 V), giving designers flexibility to trade signal amplitude against self-heating. The on-chip compensation removes the most costly external analog circuitry previously required in discrete pressure-sensor designs.
Typical applications include medical respiratory monitoring, HVAC variable-air-volume (VAV) controls, industrial process pneumatic monitoring, altimeters and barometric instrumentation, and appliance water-level detection. In respiratory monitoring, the differential configuration measures airflow across a Venturi or flow-restriction element, while in VAV controllers it measures duct static pressure to regulate damper position. In each case the 40 mV full-scale span pairs naturally with an instrumentation amplifier such as the NCS3330 to deliver a clean 0-5 V or 4-20 mA output.
When designing with this part, choose an instrumentation amplifier with low offset (under 50 uV), low noise, and high CMRR. Place the sensor close to the amplifier to avoid injecting noise into the high-impedance bridge output, and add RC low-pass filtering at the amplifier input to bandlimit acoustic and EMI noise. Use a regulated low-noise 10 V reference such as the NCP1117 or a precision reference for best ratiometric accuracy.

Aplicaciones típicas
MPXV2102DP es adecuado para 6 aplicacións: Medical Respiratory Monitoring, HVAC Variable Air Volume (VAV) Control, Industrial Pneumatic Process Monitoring, Barometric Altimeter Instrumentation, Appliance Water-Level Detection, Environmental Weather Station.
Medical Respiratory Monitoring
The MPXV2102DP fits respiratory monitoring because its 0-100 kPa differential range covers the typical breathing-circuit pressure band between 2-10 kPa peak during normal ventilation. The dual-port same-side configuration mounts across a Venturi or flow-restriction element, where the pressure differential is proportional to airflow rate. With 40 mV full-scale span at 10 V excitation and on-chip temperature compensation from 0 C to 85 C, the device maintains calibration accuracy across patient body temperature variations. Pair with the NCS3330 zero-drift instrumentation amplifier (max 10 uV offset) to deliver a clean 0-5 V signal to the host MCU. The piezoresistive silicon architecture survives autoclave sterilization and is suitable for ventilator, CPAP, and spirometer designs.
Recomendado
HVAC Variable Air Volume (VAV) Control
The MPXV2102DP is well suited to HVAC VAV control loops, where the controller measures duct static pressure between two side-by-side ports to regulate damper position. The 0-100 kPa differential range easily covers the 0-250 Pa (0-2.5 kPa) duct static band typical in commercial VAV boxes. The 8-BSOP package with dual ports on the same side simplifies tubing routing in space-constrained air-handler assemblies. On-chip temperature compensation from 0-85 C maintains span accuracy across rooftop and air-handler ambient variations, while the ratiometric output pairs naturally with the 10 V excitation rails already present in HVAC controller boards. Pair with a 4-20 mA current-loop driver (e.g., XTR105) for industrial field instrumentation.
Recomendado
Industrial Pneumatic Process Monitoring
The MPXV2102DP supports industrial pneumatic monitoring on factory air lines, robotic end-effectors, and vacuum-jacketed piping, all of which operate in the 0-100 kPa range. The differential configuration allows reference-port connection to ambient, eliminating atmospheric pressure compensation from watch conditions. The ratiometric 0-40 mV span at 10 V excitation scales predictably with the regulated industrial 24 V bus through a simple resistor divider. With -40 C to +125 C operating range and BSOP surface-mount packaging, the device withstands factory-floor vibration and thermal stress better than through-hole predecessors. Pair with a precision 24-bit sigma-delta ADC (e.g., ADS131M04) for high-resolution pressure trending.
Recomendado
Barometric Altimeter Instrumentation
The MPXV2102DP measures barometric pressure in portable altimeter designs when both ports are exposed to the same ambient, making differential output effectively gauge-referenced. The 0-100 kPa range covers the 70-105 kPa full atmospheric band from sea level to high-altitude flight, with the 40 mV span providing roughly 1 mV per kPa of resolution. On-chip temperature compensation from 0-85 C handles day-night thermal swings in outdoor portable instruments. The 8-BSOP package fits inside handheld enclosures where space is constrained and surface-mount assembly is required for production scaling. Pair with a low-power ARM Cortex-M0 MCU and a 1.5 V reference for battery-powered altimeter designs.
Recomendado
Appliance Water-Level Detection
The MPXV2102DP enables appliance water-level detection in washing machines and dishwashers, where the differential configuration compares static head pressure at the bottom of a tube to ambient pressure at the top. The 0-100 kPa range covers the typical 0-50 kPa head pressure band in standard-size washers. The on-chip temperature compensation from 0-85 C handles hot-water inlet changes without recalibration, while the BSOP package withstands the humidity and condensation cycles in appliance enclosures. Pair with a 12-bit SAR ADC and a low-cost comparator for threshold-based fill detection.
Recomendado
Environmental Weather Station
The MPXV2102DP supports low-cost weather stations measuring atmospheric pressure trends for short-term forecasting. The differential configuration with both ports exposed to ambient tracks barometric drift between 90-105 kPa with 40 mV span giving about 2.7 mV per kPa, sufficient for 0.1 kPa trend resolution with a 12-bit ADC. The on-chip calibration removes 1 percent of the analog signal conditioning that discrete designs would otherwise require. The 8-BSOP package fits solar-powered weather station enclosures, and the -40 C to +125 C range covers outdoor deployment. Pair with an I2C temperature/humidity sensor and a low-power MCU for multi-parameter logging.

Notas de diseño
The MPXV2102DP outputs a low-amplitude 0-40 mV bridge signal with source impedance around 1.1 kohm. Place the sensor amplifier within 1 k of the bridge output to minimize noise pickup on the high-impedance lines. Use a low-offset (<50 uV), low-noise instrumentation amplifier with high CMRR (>=80 dB) such as the NCS3330 or INA333. Add a 10 nF to 100 nF ceramic bypass capacitor directly across each bridge output pin to ground to filter RF and EMI noise.
Estimated: the MPXV2102DP bridge consumes approximately 5 mA at 10 V excitation. Use a low-noise, low-drift 10 V reference such as the NCP1117 or a precision reference (e.g., REF5010) for best ratiometric accuracy. The reference accuracy directly scales the output span, so a 0.1% reference is recommended for measurements requiring <1% full-scale accuracy. Decouple the excitation rail with 100 nF ceramic plus 10 uF tantalum to suppress supply noise.
Lay out the BSOP package with the two pressure ports on the same board edge to allow tube fittings to attach cleanly. Keep the bridge traces short and guarded with ground planes to minimize parasitic capacitance on the high-impedance outputs. Place the instrumentation amplifier within 25 mm of the sensor to reduce noise pickup. Add a small particle filter upstream of the ports to prevent contamination of the die cavity; NXP recommends 5-micron filtration in the pneumatic path.
Do not exceed the maximum excitation voltage of 16 V or the device will self-heat and shift calibration. Avoid applying pressure beyond the 100 kPa differential rating, which can mechanically damage the diaphragm. The compensation network on pins 5-6 must remain connected per the datasheet reference design; do not leave these pins floating. For humid or condensing environments, apply conformal coating to the BSOP package to prevent long-term corrosion.
