Hello support team.
For a current product we assemble the LMH6628WG-QML several times and we do have an issue with the current consumption. The datasheet states a max. supply current of 25mA for the whole part when no load is appliced (quiescent current).
- In my understanding this maximum value contains the impact of all effects: Initial tolerance, temperature, radiation, end of life, maybe even some margin. Is this correct?
- Do you have any detailed information on the impact on the supply current due to the individual effects?
The reason for my question is as follows:
At 25degC we measure a supply current (no load) of 16mA. So the initial tolerance is already covered. How much increase in current consumption should I consider due to temperature, radiation, end of life?
I think the increase due to temperature will be max. 1mA as the datasheet states 24mA for subgroup 1 and 25mA for subgroup 3. Is this correct?
I attached a file that shows my understanding of the individual elements that affect the supply current.
Best regards
