NPA-700B-015A

Pressure Sensors Transducers Overview

The NPA-700B-015A is a board-mount pressure sensor from the NPA series, manufactured by Amphenol Advanced Sensors. It features an absolute pressure rating of 15 PSI (103.42 kPa) with a maximum overload pressure of 60 PSI (413.69 kPa). The device utilizes a 14-bit digital I2C output interface and operates on a supply voltage range of 4.75V to 5.25V. Encased in a 14-SOIC module package with top ports, it offers ±1.5% accuracy and temperature compensation. The sensor supports surface mount installation and functions within a temperature range of -40°C to 125°C.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'A' indicates absolute pressure type, distinct from gauge variants like 'G'. Confirm the I2C address configuration requirements against the system design. Ensure the 14-SOIC package dimensions align with the PCB layout. Check RoHS compliance status for regulatory adherence. Validate supply voltage stability within the 4.75V to 5.25V window during operation.

Pressure Sensors Transducers Selection Notes

Select this model when absolute pressure measurement is required rather than gauge or differential. The 15 PSI range suits low-pressure medical and industrial applications. Choose the I2C interface for microcontroller integration without additional ADC hardware. Consider the 14-bit resolution for precision needs. Evaluate the SOIC-14 package for automated assembly compatibility.
