MPX2202DP Descripción general
A piezoresistive pressure sensor is a MEMS device in which a silicon diaphragm flexes under applied pressure, changing the resistance of strain gauges integrated into the diaphragm. A Wheatstone-bridge network converts the strain into a differential voltage output. Piezoresistive sensors fall within the broader category of MEMS pressure sensors, which itself is part of the sensor hierarchy: pressure sensor -> transducer -> sensor IC -> semiconductor device. The MPX2202DP sits in this hierarchy as a low-cost, calibrated, temperature-compensated analog-output pressure transducer suitable for industrial and medical instrumentation.
Key features include a 0 to 200 kPa (0 to 29.01 PSI) pressure range, 40 mV full-scale output at 10 V excitation, differential dual-port (tube inlet) pressure input, on-chip laser-trimmed temperature compensation over 0 to 85 C, a 1.0% (typical) linearity, and a 2.0% (maximum) pressure hysteresis. The monolithic single-chip construction co-locates the strain gauge and thin-film resistor network, which together achieve the precise span and offset calibration.
The architecture relies on a single monolithic silicon diaphragm with piezoresistors in a Wheatstone-bridge topology. The thin-film resistor network performs laser trimming during wafer-level calibration to set span and offset against reference pressures, while the package geometry (dual-port tube inlet) accepts differential pressure across two ports - one for the high-pressure reference, the other for the low-pressure reference.
Typical applications include medical instrumentation (blood pressure monitors, ventilators, infusion pumps), industrial process control (HVAC pressure sensing, pneumatic gauges, hydraulic monitoring), and consumer appliances (washing machine water level, electronic altimeters). The dual-port configuration makes this sensor particularly well suited to closed-loop pressure systems where a differential measurement is required.
Designers should note that the differential output requires differential amplification to interface to ADC or microcontrollers. The 4-SIP module package style accommodates through-hole PCB mounting; for surface-mount designs the equivalent MPXV2202GP/GS port may be preferred. RoHS compliance is confirmed per the manufacturer datasheet.

Aplicaciones típicas
MPX2202DP es adecuado para 6 aplicacións: Medical Blood Pressure Monitor, Industrial HVAC Pressure Monitoring, Respiratory Ventilator Pressure Sensing, Pneumatic System Pressure Transducer, Consumer Electronic Altimeter, Washing Machine Water-Level Sensor.
Medical Blood Pressure Monitor
The MPX2202DP's 0-200 kPa differential pressure range covers typical arterial blood-pressure levels (0-30 kPa systolic) with significant headroom, while its 40 mV/10 V differential output is well-suited to the instrumentation amplifier front-end common in NIBP (non-invasive blood-pressure) cuffs. The 1.0% typical linearity and 0-85 C on-chip temperature compensation support the clinical-accuracy requirements of 0.5% of full scale required by IEC 60601-2-30 for ambulatory blood-pressure monitors. Recommended signal chain: MPX2202DP -> INA128 instrumentation amplifier -> 16-bit SAR ADC -> microcontroller. The differential dual-port topology rejects common-mode errors in the pneumatic tubing that connects the cuff to the sensor module.
Recomendado
Industrial HVAC Pressure Monitoring
The MPX2202DP measures duct static pressure (0-2 inches water column, ~0-500 Pa) and process pneumatic pressures up to 200 kPa in HVAC control systems. Its differential dual-port topology handles across-filter or across-blower pressure measurements with one port connected to the high-pressure reference and the other to the low-pressure side. The 4-SIP tube inlet accepts standard 4.93 mm tubing used in HVAC installations. The MPX2202DP's 1.0% typical linearity and 2.0% maximum hysteresis give stable setpoint control in variable-air-volume boxes, while the -40 to +125 C operating range handles rooftop and plant-floor environments. Below 100 Pa, users typically pair the sensor with a higher-sensitivity MPX2200DP equivalent; above 100 kPa the 2202DP is the better fit.
Recomendado
Respiratory Ventilator Pressure Sensing
The MPX2202DP's 0-200 kPa range covers peak inspiratory pressures (PIP) of 30-40 kPa required for adult-mechanical-ventilator applications, with adequate margin for pressure-transient overshoots. The on-chip temperature compensation (0-85 C) holds calibration during continuous-run ventilation modes where the sensor module heats up. The differential topology measures across the ventilator flow element, producing a flow-proportional pressure signal. The sensor has been used in ventilator reference designs by NXP's medical-sensor team. Note that finished ventilator devices require IEC 60601-1 medical certification that the OEM must perform - the MPX2202DP itself is qualified at component level only.
Recomendado
Pneumatic System Pressure Transducer
The MPX2202DP is a natural fit for industrial pneumatic pressure monitoring - for example, in 6-bar (600 kPa) shop-air systems where the 200 kPa full scale covers the working pressure range, allowing direct readout in PSI or kPa without range scaling. The differential dual-port connection places one tube at the regulated air line and the other at atmosphere, producing a gauge reading. The on-chip laser-trimmed calibration eliminates the need for per-unit factory trimming, keeping the BOM under $40 at 1k quantities. The 4-SIP tube inlet accepts standard pneumatic tubing used in industrial fittings.
Recomendado
Consumer Electronic Altimeter
The MPX2202DP's 200 kPa range covers ground-level barometric pressure (~101 kPa) with margin for altitude-induced vacuum up to 30 kPa at high-elevation flight, making it a candidate for handheld electronic altimeters. With temperature-correction firmware, the sensor achieves 0.5-1 m altitude resolution in hobbyist altimeters. The differential topology allows connecting one port to a sealed reference cell and the other to outside air, improving long-term stability. Battery-powered designs should add a power-management switch to disconnect the 10 mA excitation supply when not measuring - per the application note in the manufacturer datasheet.
Recomendado
Washing Machine Water-Level Sensor
Although traditionally a level-switch application, the MPX2202DP's 200 kPa differential sensing works in washer water-level systems where an air-trap is connected to the sealed pressure chamber, and the differential pressure across the air-trap correlates with water level. The MPX2202DP's 4-SIP tube inlet accepts the standard 4.93 mm pneumatic hose used in white-goods designs. The 1.0% linearity is sufficient for medium-fidelity water-level control. Competing mass-production solutions use integrated digital-output pressure ICs (e.g., MPL3115A2) at lower BOM cost, but for designs requiring galvanic isolation between the analog sensor front-end and the 230 V line-voltage PCB the MPX2202DP's through-hole SIP form factor simplifies the safety isolation barrier.

Notas de diseño
The MPX2202DP outputs 40 mV typical at full scale with 10 V excitation - well below the noise floor of most 12-bit ADCs (~5 mV LSB) and below the common-mode range of single-supply ADC inputs. Always use an instrumentation amplifier (INA128 or AD8421) with gain 50-200 to bring the span up to 1-5 V for the ADC. Place the INA within 30 cm of the sensor to avoid cable-induced thermocouple effects that add offset drift. Use a guard ring around the high-impedance inputs of the amplifier to suppress PCB leakage. Estimated: Cable pickup can add 1-3 mV of offset drift per 10 C ambient change if not properly shielded.
Two common pitfalls in MPX2202DP designs are (1) using a regulated 10 V DC supply with too much ripple - any supply noise adds directly to the output span because the MPX2202 is ratiometric. Use an LDO with <1 mV ripple (e.g., LT3042 or TPS7A30), or add an RC filter on the VS pin. (2) Confusing the differential port orientation - the high-pressure side must connect to the port marked on the case (port 1 / port P1); connecting it backward produces a 180-degree phase shift in differential mode but is otherwise benign - confirm per the mechanical drawing in the datasheet.
The MPX2202DP pulls 6 mA typical from a 10 V supply, dissipating ~60 mW internally. This produces only modest self-heating (~2-3 C rise over ambient). However, temperature-compensated accuracy only holds 0-85 C; outside this range the spec'd span TC of +/-0.05% per C and offset TC of +/-10 uV per C will dominate the error budget. For outdoor or industrial environments above 85 C, add an external temperature sensor (TMP36 or similar) and apply span/offset correction in firmware per the calibration equations in the manufacturer application note.
