NPA-300B-030A

Pressure Sensors Transducers Overview

The NPA-300B-030A is an absolute pressure sensor from the NPA-300 series by Amphenol Advanced Sensors. It features a 14-bit analog voltage output ranging from 2V to 3V, powered by a supply voltage of 3.135V to 3.465V. The device has a working pressure of 30PSI (206.84kPa) and a maximum pressure rating of 60PSI (413.69kPa). It offers ±1.5% accuracy and operates within a temperature range of -40°C to 125°C. The sensor utilizes a 14-SOIC module package with top ports and gull wing termination.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'A' corresponds to the 30PSI absolute pressure variant with 2V-3V output. Confirm the 14-SOIC package type and dual barbed port configuration match the application requirements. Ensure the supply voltage range of 3.135V to 3.465V aligns with the target circuit design. Check for RoHS compliance and moisture sensitivity level 5A handling precautions during assembly.

Pressure Sensors Transducers Selection Notes

Select this component when a digital I2C interface is not required and an amplified analog voltage signal is preferred. The 30PSI range suits low-pressure applications requiring high resolution via the 14-bit internal ADC. Consider the ±1.5% accuracy and wide temperature range for environments demanding reliable calibration without external compensation circuits.

Pressure Sensors Transducers Part Context

This part belongs to the NPA-300 series of MEMS pressure sensors. It shares the same physical footprint and pinout with other variants in the series that differ in pressure range or output type. The NPA-300B designation indicates a specific configuration within the broader NovaSensor portfolio designed for board-mounted integration.

Pressure Sensors Transducers Replacement Considerations

Direct substitutes include other NPA-300 series parts with identical packaging but different pressure ratings, such as NPA-300B-005G for lower pressure needs. Cross-series replacements like NPA-700B-030A offer similar functionality but feature I2C digital output instead of analog voltage, requiring interface adaptation.
