MPVZ5150GC7U 개요
A piezoresistive transducer, also called a MEMS pressure sensor or silicon strain-gauge sensor, is a device that converts applied pressure into a small differential voltage using diffused resistors on a silicon diaphragm. The on-chip ASIC conditions this raw signal, applies temperature compensation across the -40 °C to +125 °C range, and normalizes the output so the device produces a near-linear analog voltage directly readable by an MCU ADC.
Key features include ±1.5 % maximum pressure accuracy over 0 °C to 85 °C, an ratiometric analog output proportional to a 4.75 V to 5.25 V supply, and a typical response time of 1.0 ms. The 8-DIP through-hole package (10.67 x 10.67 x 12.96 mm) simplifies prototyping and breadboarding, while the integrated calibration eliminates external compensation components. The device also provides ESD protection rated above 1000 V HBM on sensor pins per industry test methods.
Typical applications include HVAC pressure monitoring, medical respiratory equipment, weather stations, altimeters, industrial process control, and appliance water-level sensing. Because the output spans nearly the full 0-5 V ADC range of most 5 V microcontrollers, no external amplifier is needed in many designs. The vented gauge reference makes it ideal for applications where barometric compensation is desired, such as portable altimeters and weather instruments.
When designing with this part, add a 0.01 µF to 0.1 µF decoupling capacitor close to VDD, and consider a low-pass RC filter on VOUT if the host ADC is sensitive to high-frequency noise. Avoid liquids contacting the silicone gel coating inside the port, and route the supply trace away from switching nodes to preserve the ratiometric accuracy.

일반적인 애플리케이션
MPVZ5150GC7U 적합 용도: 6 애플리케이션s: Barometric Weather Stations, HVAC Airflow & Duct Monitoring, Medical Respiratory Equipment, Industrial Process Pressure Monitoring, Portable Altimeters & Handheld Instruments, Appliance Water-Level Sensing (Pneumatic Method).
Barometric Weather Stations
The MPVZ5150GC7U's 0 to 150 kPa vented gauge range matches the barometric pressure envelope (typically 87 to 108 kPa at sea level) with full scale headroom. Its 0.2 V to 4.7 V ratiometric output drives a 5 V MCU ADC directly, providing approximately 4.5 mV/Pa of usable resolution. The vented gauge reference means the back of the die equalizes to ambient pressure through the port, so no separate barometric correction is needed when the enclosure is also vented to atmosphere.
추천
HVAC Airflow & Duct Monitoring
In HVAC duct pressure monitoring the MPVZ5150GC7U delivers 0.2 V to 4.7 V for 0 to 150 kPa, well above the typical 0 to 2.5 kPa duct static pressure range, giving the ADC ample resolution at the low end. The 1 ms response time tracks fan-induced pressure fluctuations, while the integrated temperature compensation holds ±1.5 % accuracy across the 0 to 85 °C control-loop range. The top-port tube inlet connects directly to a pitot or static pressure probe without tubing adapters.
추천
Medical Respiratory Equipment
The MPVZ5150GC7U's ±1.5 % accuracy over 0 °C to 85 °C and 1 ms response support breath-cycle pressure sensing in CPAP, ventilator, and spirometer designs within the 0 to 150 kPa range. The silicone-gel isolation protects the die from exhaled humidity and condensate. The ratiometric 0.2 V to 4.7 V output can drive the ADC of an ARM Cortex-M medical MCU. Compliance documentation for medical use is the integrator's responsibility, not the component vendor's.
추천
Industrial Process Pressure Monitoring
The MPVZ5150GC7U handles non-corrosive industrial gases up to 150 kPa with on-chip calibration, making it well matched to factory pneumatic lines, filter-status indicators, and tank-head pressure monitoring. The 8-DIP through-hole package simplifies hand-soldered prototypes and field replacements, and the -40 °C to +125 °C operating range covers most indoor industrial environments. The output is ratiometric to VDD, so drift in the 5 V supply scales both VDD and VOUT together, keeping calibration intact.
추천
Portable Altimeters & Handheld Instruments
The MPVZ5150GC7U's 0 to 150 kPa range covers the full atmospheric envelope from sea level to about 12 km altitude, where barometric pressure drops to ~20 kPa. The vented gauge reference means the sensor subtracts weather-driven pressure changes automatically when used in an altitude-hold application, simplifying firmware. Battery-powered designs benefit from the modest 5 V supply current, and the 8-DIP through-hole package simplifies hand assembly for low-volume handheld runs.
추천
Appliance Water-Level Sensing (Pneumatic Method)
In pneumatic water-level sensors, a tube routed to the bottom of a tank delivers trapped air pressure to the MPVZ5150GC7U proportional to water column. With 150 kPa full scale, the sensor can measure water columns up to about 15 m, covering most residential appliance and small-tank use cases. The silicone-gel isolation protects the die from occasional condensation. The vented gauge configuration requires the sensor housing to be at atmospheric pressure, achieved through the top-port vent path.

설계 노트
Decouple VDD (pin 4) with a 0.01 µF to 0.1 µF ceramic capacitor placed within 5 mm of the package pin, with a ground return on a low-impedance plane. The MPVZ5150GC7U draws modest supply current at 5 V, but the on-chip ASIC is sensitive to high-frequency VDD noise. Route VDD away from switching nodes such as DC-DC inductor traces. The ratiometric output scales with VDD, so a clean 5 V rail is essential for accuracy.
Keep the top-port pressure inlet clear of solder flux, conformal coating, and debris - any blockage or film on the silicone gel will bias the reading. Use a 0.1 inch (2.54 mm) pitch 8-DIP socket or hand-solder the through-hole leads with proper thermal relief. Route VOUT in a guarded trace or shielded layer if the host PCB has switching converters; long unshielded traces degrade the ADC reading by injecting 5 V switching noise into the analog signal.
Place a first-order RC low-pass filter (R=1 kΩ, C=100 nF) on VOUT close to the MCU ADC pin to suppress high-frequency noise from the MCU's switching I/O. The MPVZ5150GC7U bandwidth is approximately 1 kHz, so a 1.6 kHz filter corner is appropriate. Use the MCU's internal averaging of 16+ samples to further reduce noise. Verify the filter does not significantly slow the pressure response for fast-changing applications such as respiratory sensing.
Estimated: when adapting the MPVZ5150GC7U to a 3.3 V MCU ADC, use a 1:1.5 resistor divider on VOUT to avoid saturating the ADC at the upper end of the range. Do not connect liquid lines directly to the top port - the silicone gel isolation is rated for dry air and non-corrosive gases only, and liquid ingress permanently biases the sensor. Do not apply pressure beyond the datasheet-specified maximum overload, as this may crack the silicon diaphragm and cause catastrophic failure.
