Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'C' against official documentation to confirm the SOIC package type and commercial temperature rating. Ensure the ordering information matches the required resolution class (16-bit, 17-bit, or 18-bit) as the base model supports multiple variants. Confirm availability through authorized distributors as lead times may vary.

Analog To Digital Converters (ADC) Selection Notes

Select appropriate external integrating resistor (RINT) within the 50kΩ to 150kΩ range to optimize noise and linearity. Choose integrating capacitors with low dielectric absorption, such as polypropylene types, to minimize charge loss errors. Ensure the clock frequency selection aligns with the desired integration time for effective 50/60Hz line frequency rejection.
