MPVZ5004G7U 概要
A piezoresistive pressure sensor is a transducer in which strain gauges diffused into a silicon diaphragm change resistance under mechanical stress, producing an electrical signal proportional to applied pressure. The MPVZ5004G7U belongs to the MPxx5004 family of integrated pressure sensors, sitting in the hierarchy: pressure transducer -> piezoresistive sensor -> signal-conditioned pressure sensor IC -> MEMS sensor -> semiconductor. Compared with bare MEMS dies, integrated parts like this combine the sense element, amplifier, and trim network on one chip, eliminating most external components in a typical circuit.
Key features include a ratiometric 5 V supply operation, 1.0 V to 4.9 V analog output swing across the calibrated pressure range, integrated temperature compensation from 0C to 85C, on-chip calibration, and a vented gauge port that references the back side of the diaphragm to ambient. The DIP-8 module is designed for through-hole mounting with an axial pressure port and includes a gel-protected die for moisture resistance in non-condensing environments.
The architecture uses bipolar signal conditioning with laser-trimmed resistors to calibrate offset and full-scale at the factory, so end users do not need to perform extensive external compensation. The device exhibits typical pressure linearity within +/-1.5% of full-scale span and is designed for smooth monotonic output over the entire pressure range.
Typical applications include medical respiratory equipment, HVAC pressure monitoring, air-flow and differential-pressure sensing, appliance vacuum sensing, and other low-pressure instrumentation where a calibrated analog output is preferred over a raw bridge output.
When designing with the MPVZ5004G7U, decouple the supply pin with a 0.1 uF ceramic capacitor placed close to the device. Because the output is ratiometric, connect the ADC reference to the same 5 V rail as the sensor to preserve accuracy. Avoid exposing the gel-coated port to condensing humidity or direct water contact.

主な用途
MPVZ5004G7U の用途: 6 件s: Medical Respiratory Airflow Sensing, HVAC Duct Static Pressure Monitoring, Appliance Vacuum Sensor, Air-Flow and Differential Pressure Sensing, Portable Health Monitoring Devices, Industrial Process Gas Pressure Monitoring.
Medical Respiratory Airflow Sensing
The MPVZ5004G7U's 0 to 3.92 kPa calibrated range matches typical respiratory pressure drops across flow heads in CPAP and ventilator circuits, where pressures stay well under 0.57 PSI even during peak inspiratory flow. With a ratiometric 1.0 V to 4.9 V output the sensor can drive an ADC directly, simplifying the analog front end of bedside monitors. Its on-chip temperature compensation from 0C to 85C keeps calibration stable across body-temperature-conditioned airstreams, and the gel-protected axial port tolerates patient-room humidity. Compared with bare MEMS bridges, the integrated MPVZ5004G7U removes the need for external amplifiers and trim resistors, cutting the BOM for medical devices and shortening FDA documentation cycles for the analog signal path.
おすすめ
HVAC Duct Static Pressure Monitoring
Building HVAC systems monitor duct static pressure to balance airflow across variable-air-volume boxes, and the MPVZ5004G7U's 0 to 3.92 kPa range covers the typical 0 to 1.5 inch water column (0.37 kPa) operating window with comfortable headroom. The ratiometric analog output is easy to feed into a 4-20 mA loop transmitter or directly into a controller's ADC, and the on-chip calibration eliminates the per-unit trim step required by bare MEMS bridges. Designers should bias the device from the same 5 V rail that drives the ADC reference to keep the reading ratiometric across supply variations. The DIP axial port allows convenient pneumatic tubing connection to a static pressure probe.
おすすめ
Appliance Vacuum Sensor
Vacuum cleaners, autoclaves, and similar appliances use low-pressure feedback to control motor speed and detect filter blockage, and the MPVZ5004G7U's 1.0 V to 4.9 V swing at 0.57 PSI full scale is well matched to the typical 10 to 20 kPa vacuum operating point of such systems. The integrated temperature compensation and factory calibration remove the need for end-of-line software trim, simplifying firmware and shortening production test time. The DIP-8 axial port accepts standard pneumatic fittings used in white-goods manufacturing lines. Power consumption is set by the supply rail, making the device compatible with energy-star standby budgets in mains-powered appliances.
おすすめ
Air-Flow and Differential Pressure Sensing
Differential pressure across an orifice plate is a common way to derive volumetric air flow, and the MPVZ5004G7U's sub-PSI full scale suits low-flow laboratory and process-gas instrumentation. Because the output is ratiometric to 5 V, the sensor pairs naturally with delta-sigma ADCs whose reference is tied to the same rail, preserving conversion accuracy across supply variation. The 0.57 PSI range gives engineers headroom over typical 0.1 inch water column (about 25 Pa) sensing taps used in cleanroom and fume-hood monitoring. The DIP-8 package is convenient for breadboarding flow benches where axial pneumatic connections are standard.
おすすめ
Portable Health Monitoring Devices
Wearable spirometers, sleep-apnea monitors, and similar portable health devices benefit from the MPVZ5004G7U's integrated calibration because end-of-line trim is impractical in a high-volume consumer roll-out. The 0.57 PSI range is well suited to the small differential pressures generated by breathing through a flow head, while the on-chip temperature compensation holds accuracy as the device warms on a patient's body. Ratiometric 5 V output is compatible with battery-boosted rails in USB-rechargeable wearables, and the low-profile DIP module fits standard enclosure openings. Designers should add a particulate inlet filter to protect the gel port from contamination in field use.
おすすめ
Industrial Process Gas Pressure Monitoring
Process-gas panels often require accurate low-pressure telemetry in the 0 to 3 kPa region for leak detection and flow balancing, and the MPVZ5004G7U's calibrated 1 V/kPa sensitivity simplifies analog scaling and HMI engineering. The integrated signal conditioning removes the noise and drift typically introduced by external op-amps sitting near solenoid and motor drive circuits, while the 8-DIP module's through-hole mount provides the vibration tolerance needed in industrial enclosures. The vented-gauge configuration is appropriate for non-corrosive gases; for corrosive media, designers should mount a compatible inline filter at the port to protect the gel sensor.

設計ノート
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VCC pin to suppress switching noise from upstream regulators. Because the MPVZ5004G7U output is ratiometric to the supply, tying the ADC reference to the same 5 V rail preserves accuracy across supply tolerance. A 10 uF bulk capacitor at the board's 5 V input helps reject motor back-EMF in appliance designs.
Do not expose the gel-coated axial port to condensing humidity, water immersion, or direct dust streams; use a sintered inlet filter for field-deployed instrumentation. Avoid routing high-current traces (42 AWG power, motor drive) directly under the DIP module - noise couples capacitively into the strain-gauge bridge and shows up as pressure-reading jitter.
For surface-mount designs where the through-hole MPVZ5004G7U is not suitable, switch to the SMT sibling MPVZ4006G6T1 or MPXV5004G series. Maintain a quiet analog ground island around the sensor, returning sensor GND directly to the ADC ground pin rather than sharing a high-current return path.
コンプライアンス情報
