Voltage Reference Procurement Notes

Verify the specific suffix 'AIX3' against official manufacturer documentation, as standard Maxim Integrated nomenclature typically utilizes 'EX3' for SC-70 packages. Confirm that the 'T' suffix denotes tape-and-reel packaging and that the '+T' designation aligns with current lead-free RoHS compliance standards. Cross-reference the part number with Texas Instruments or Analog Devices databases to ensure accurate component identification before procurement.

Voltage Reference Selection Notes

Select this component when a compact footprint is required alongside high precision. The 4.096V output is suitable for driving ADCs in industrial sensors. Ensure the circuit design accommodates the minimum 60µA cathode current to maintain regulation. Verify that the thermal environment remains within the specified -40°C to +125°C operational range for guaranteed performance.
