NPA-730B-001D

Pressure Sensors Transducers Overview

The NPA-730B-001D is a differential pressure sensor from the Amphenol Advanced Sensors (NovaSensor) NPA series. It features a 14-bit digital output via an I2C interface, housed in a 14-SOIC module package with top dual ports. The device operates on a supply voltage of 3.135V to 3.465V and measures a working pressure of 1 PSI (6.89 kPa). It offers ±1.5% accuracy and supports a maximum pressure of 5 PSI (34.47 kPa). The sensor includes temperature compensation and functions within a temperature range of -40°C to 125°C.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'B' indicates gauge pressure type and '001' denotes the 1 PSI range against the official datasheet. Confirm port style matches application requirements. Check moisture sensitivity level handling procedures prior to assembly. Ensure I2C address configuration aligns with system design constraints.

Pressure Sensors Transducers Selection Notes

Select this component when a low-pressure differential or gauge measurement is required with digital integration. Compare against NPA-730N variants if absolute pressure sensing is needed instead. Evaluate pin compatibility and thermal performance against other NPA series members for board space optimization.

Pressure Sensors Transducers Part Context

This part belongs to the NPA-730 series of digital MEMS pressure sensors. It shares the same 14-SOIC footprint and I2C communication protocol as other models in the family, differing primarily in pressure range and port configuration. It complements analog-output sensors like the NPA-300 series by providing direct microcontroller interfacing.
