Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix (e.g., UA vs. UAKR) against the manufacturer's official datasheet to ensure correct packaging and temperature grade. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the component marking code with the latest TI documentation to authenticate the source and prevent counterfeit risks during acquisition.

Sensor And Detector Interfaces Selection Notes

Select this component when designing two-wire transmitters that require integrated sensor power and linearization. Ensure the input signal range aligns with the specified 1.25 V to 3.5 V limits. Verify that the SOIC-14 package fits the PCB layout constraints. Consider thermal performance within the -40°C to +85°C operating range for the intended environment.
