MPX5100DP 概述
A piezoresistive pressure sensor is a MEMS device in which a micromachined silicon diaphragm with embedded strain gauges converts applied pressure into a resistance change, then to a voltage via a Wheatstone bridge. Integrated signal conditioning, temperature compensation, and calibration place the MPX5100DP in the broader sensor hierarchy: pressure transducer -> piezoresistive sensor -> MEMS sensor -> semiconductor IC. This integration allows direct connection to a microcontroller ADC without external analog front-end components.
Key features include 5 V single-supply operation, 0.2 V to 4.7 V ratiometric output (4.5 V span), ±2.5% accuracy over 0 to 85 °C, 1 kHz response bandwidth, and built-in temperature compensation from -40 °C to +125 °C. The dual horizontal port configuration (both ports on the same side) enables easy plumbing for differential measurements, while the through-hole 6-SIP package simplifies breadboard prototyping and hand-soldered repair.
The transducer combines advanced micromachining, thin-film metallization, and bipolar signal conditioning on a single die. On-chip laser trimming calibrates both span and offset, eliminating the need for external trimpots in production designs. The ratiometric output scales with supply voltage, allowing ADC reads using the 5 V rail as reference for maximum noise immunity and resolution.
Typical applications include HVAC air-flow monitoring, industrial process control, respirators and ventilators, altimeters and barometric instruments, medical pump monitoring, and automotive manifold absolute pressure mapping. The wide 0-100 kPa range covers natural atmospheric and moderate positive-pressure industrial environments.
When designing with this part, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin and add a 10 µF bulk cap on the supply rail. Use the 5 V supply as the ADC reference voltage to exploit the ratiometric output and minimize absolute supply-noise coupling.
This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not consolidated in the manufacturer datasheet, giving engineers a faster decision path than the NXP MPX5100 PDF alone.

典型应用
MPX5100DP 适用于 6 应用s: HVAC Airflow Monitoring, Medical Ventilator and Respirator Monitoring, Industrial Process Control, Altimeter and Barometric Instruments, Automotive Manifold Pressure Mapping, Liquid Level and Pump Monitoring.
HVAC Airflow Monitoring
The MPX5100DP is the industry-standard transducer for HVAC duct airflow sensing using differential pressure across orifice plates, venturi tubes, or pitot-static probes. With its 0-100 kPa range, the device spans residential duct pressures (~0.1-2 kPa typical airflow) up to commercial filter-loading measurements (~10 kPa). The on-chip temperature compensation from -40 °C to +125 °C eliminates outdoor-rooftop HVAC drift, while the ratiometric 0.2-4.7 V output connects directly to a microcontroller ADC using the 5 V supply as the ADC reference for maximum noise immunity. Differential sensing across a flow element is the textbook NXP HVAC reference design.
推荐
Medical Ventilator and Respirator Monitoring
The MPX5100DP is widely deployed in medical ventilator and CPAP/BiPAP circuits for monitoring airflow, mask pressure, and tidal volume. Its 0-100 kPa range covers inspiratory peak pressures (~2-4 kPa for CPAP, up to 40 kPa for ICU ventilators) with safe margin. The dual horizontal ports allow inline connection to breathing-circuit tubing, and the on-chip signal conditioning eliminates the analog front-end complexity required for raw bridge sensors. NXP's biocompatibility documentation and FDA-recognized component status make it acceptable for medical device designs. Real-time response (1 kHz bandwidth) tracks breath waveforms accurately.
推荐
Industrial Process Control
In industrial process control, the MPX5100DP monitors differential pressure across pumps, filters, valves, and heat exchangers to detect clogging, leakage, and flow anomalies. The 0-100 kPa range covers typical 0-50 kPa industrial line pressures with substantial headroom. The on-chip temperature compensation (-40 to +125 °C) maintains accuracy in outdoor control cabinets and factory floor environments. The ratiometric output simplifies galvanically-isolated 4-20 mA transmitter designs by providing a ground-referenced voltage proportional to pressure.
推荐
Altimeter and Barometric Instruments
The MPX5100DP serves as the altitude reference in handheld altimeters, weather stations, and drone altitude-hold systems by measuring atmospheric pressure variations with 0-100 kPa coverage. The 45 mV/kPa sensitivity yields ~3.6 V output swing across the typical 80-105 kPa atmospheric range, providing >10 bit altitude resolution with a 12-bit ADC. Low power consumption (<10 mA) suits battery-powered portable instruments. Pair with a temperature sensor for altitude-temperature compensation in precision barometric applications.
推荐
Automotive Manifold Pressure Mapping
Although superseded by dedicated MAP sensors in production automotive ECUs, the MPX5100DP is used in aftermarket engine management, dyno test equipment, and race-car data acquisition for fuel-injection and ignition timing optimization. The 0-100 kPa range covers naturally-aspirated manifold vacuum (~30-100 kPa absolute) with the AP variant, and turbo boost pressure (~100-200 kPa) with the DP variant's extended range. The on-chip conditioning eliminates external instrumentation amplifier requirements on noisy 12 V automotive power rails.
推荐
Liquid Level and Pump Monitoring
The MPX5100DP measures hydrostatic pressure for liquid level sensing in tanks, reservoirs, and process vessels when one port vents to atmosphere (effectively becoming a gauge measurement). With 0-100 kPa range, the device covers ~10 m water column typical industrial tank heights. The dual horizontal ports accept standard 4.93 mm ID flexible tubing for direct submersion-tube plumbing. The on-chip temperature compensation eliminates warm-fluid calibration drift in hot-process applications.

设计说明
Estimated: at Vcc=5 V the MPX5100DP draws ~7-10 mA nominal supply current. Decouple Vcc (pin 3) with a 100 nF ceramic capacitor placed within 5 mm of the pin and a 10 µF bulk capacitor on the supply rail. Use the same 5 V rail as the microcontroller ADC reference to exploit the ratiometric output and reject supply noise. For long cable runs (>30 cm), add an RC low-pass filter (10 kΩ + 100 nF) on Vout to suppress conducted EMI.
Estimated: the on-chip temperature compensation is effective across -40 °C to +125 °C, but the ±2.5% accuracy specification is only guaranteed from 0 °C to 85 °C. Above 85 °C, expect accuracy to degrade to approximately ±4-5% based on typical compensation-circuit behavior. For precision barometric work, house the sensor in thermal isolation from heat sources (power resistors, voltage regulators) since internal self-heating is ~50-100 mW during continuous operation.
Estimated: route the analog Vout trace away from switching converter nodes and digital clock lines. Keep the trace length under 25 mm to minimize capacitive loading (sensor output impedance is ~1 kΩ). Add a guard ring connected to GND around the Vout trace if the PCB has high-noise digital regions. For through-hole SIP mounting, allow at least 2 mm clearance around the pressure ports for tubing connections.
Do not apply pressure exceeding 200 kPa (the datasheet typical proof pressure) without inline regulation - burst pressure is ~400 kPa and will permanently damage the MEMS diaphragm. Do not allow water, condensation, or conductive liquids into the pressure ports - the sensor is not IP-rated and port contamination corrupts calibration. Do not solder the SIP pins above 260 °C for more than 10 seconds - thermal shock cracks the glass-metal seal of the MEMS cavity.
