Pressure Sensors Transducers Procurement Notes

Verify that the specific order matches the NPA-730N-005D part number to ensure correct differential pressure rating and I2C interface. Confirm that the application environment remains within the specified -40°C to +125°C temperature limits. Check humidity sensitivity handling requirements during storage and assembly, as the component is moisture sensitive. Ensure the host system provides the required 3.135V to 3.465V supply voltage for proper operation.

Pressure Sensors Transducers Selection Notes

Select this model when a digital I2C interface is preferred over analog outputs for direct microcontroller connection. Choose this variant for differential pressure measurement rather than absolute or gauge configurations. Consider the 14-bit resolution and ±1.5% accuracy for applications requiring moderate precision in a small SOIC-14 footprint. Verify that the 5 PSI working pressure range meets the specific system requirements.
