NPA-700B-030G

Pressure Sensors Transducers Overview

The NPA-700B-030G is a board-mount pressure sensor from the NPA-700 series, manufactured by Amphenol Advanced Sensors. It features an I2C digital output with 14-bit resolution and operates on a supply voltage of 4.75V to 5.25V. The device measures gauge pressure with a working range of 30PSI (206.84kPa) and a maximum pressure of 60PSI (413.69kPa). Accuracy is specified at ±1.5%. It utilizes a 14-SOIC module package with top ports and supports temperature compensation across a wide operating range of -40°C to 125°C.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'G' confirms the 30PSI gauge pressure rating and I2C digital output configuration. Ensure the procurement order specifies the correct tape-and-reel packaging format compatible with SMT placement equipment. Confirm that the required supply voltage aligns with the 4.75V to 5.25V specification before integration into the final system design.

Pressure Sensors Transducers Selection Notes

Select this component when a digital I2C interface is required for precise pressure monitoring in space-constrained medical or industrial applications. The 14-bit resolution provides sufficient detail for most flow control loops. Consider the 14-SOIC package dimensions for PCB layout constraints and verify that the 30PSI working pressure range meets the system's operational limits without exceeding the 60PSI burst pressure.

Pressure Sensors Transducers Part Context

This part belongs to the NPA-700 series of MEMS pressure sensors, which are designed for low-pressure applications. The series offers various pressure ranges and output types, including analog and digital options. The NPA-700B variant specifically denotes the gauge pressure configuration within this family, providing a standardized solution for OEM designers seeking reliable, calibrated sensing elements.

Pressure Sensors Transducers Replacement Considerations

Direct substitutes within the same series include NPA-700B-015G for lower pressure ranges or NPA-700B-050G for higher pressure ratings, provided the I2C interface and package remain consistent. Cross-series replacements require verification of pin compatibility and electrical specifications.
