ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus 'TR' or other variants in official documentation. Confirm current availability status as distribution channels may list limited stock or discontinuation notices. Check RoHS3 compliance certificates and REACH status for regulatory adherence in target markets.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring a complete 3.5-digit ADC solution with minimal external components. Ensure the design accommodates the 44-MQFP footprint and thermal requirements given the 889 mW power dissipation. Verify that the 2.5V to 7V supply range aligns with system power constraints and that the 0°C to +70°C industrial temperature range meets environmental specifications.
