NPA-730B-030A

Pressure Sensors Transducers Overview

The NPA-730B-030A is a digital absolute pressure sensor from the NPA-730 series by Amphenol Advanced Sensors. It features a 14-bit I2C output and operates within a supply voltage range of 4.75V to 5.25V. The device measures pressures up to 30PSI (206.84kPa) with a maximum pressure rating of 60PSI (413.69kPa). It utilizes a 14-SOIC module package with dual top ports sized at 0.12 inches (3mm). Key specifications include ±1.5% accuracy, temperature compensation, and an operating temperature range of -40°C to 125°C.

Pressure Sensors Transducers Applications

• Board-level medical device pressure monitoring
• Industrial process control systems requiring absolute pressure data
• HVAC equipment with digital communication interfaces

Pressure Sensors Transducers Procurement Notes

Verify that the specific part number matches the required absolute pressure reference type, as gauge variants exist within the same series. Confirm the 14-SOIC package orientation and port configuration align with the PCB layout. Ensure the power supply strictly adheres to the 4.75V to 5.25V specification to maintain signal integrity and accuracy. Check RoHS compliance status if environmental regulations apply to the final assembly.

Pressure Sensors Transducers Selection Notes

Select this component when a digital I2C output is preferred over analog signals to simplify system architecture. The 30PSI range suits low-pressure applications where high precision is not critical compared to higher-grade sensors. Consider the surface-mount form factor for automated assembly processes. Evaluate the ±1.5% accuracy against application tolerances before choosing alternative models with tighter error bands.

Pressure Sensors Transducers Part Context

This sensor belongs to the NPA-730 series, which focuses on digital pressure sensing solutions. It shares the NPA-700 family's MEMS technology but differs in specific electrical characteristics and port configurations. The series targets applications needing reliable, calibrated pressure data without external signal conditioning circuits.

Pressure Sensors Transducers Replacement Considerations

NPA-700B-030A offers similar physical dimensions and pressure range but may differ in supply voltage requirements or internal calibration profiles. Verify pin-to-pin compatibility and software register mapping before substitution.
