NPA-700B-05WG

Pressure Sensors Transducers Overview

The NPA-700B-05WG is a differential pressure sensor from the Amphenol Advanced Sensors NPA-700 series, designed for surface mount PCB integration. It features a 14-bit digital I2C output and operates within a supply voltage range of 4.75V to 5.25V. The device measures a working pressure of 0.18 PSI (1.25 kPa) with a maximum overpressure capability of 60 PSI (413.69 kPa). It utilizes a 14-SOIC package with top-mounted dual barbless ports measuring 0.028 inches (0.72 mm). The sensor includes temperature compensation and maintains an accuracy of ±1.5% across an operating temperature range of -40°C to 125°C.
