Hi All,

 

According to the ADG1311 data sheet, Idd is 380uA max when the digital inputs are 5V.

Then I have a question. Which one of the following three is correct about Idd?

  1. When all four inputs are applied to 5V, the Idd value become 380uAx4=1,520uA max.
  2. The 380uA is the total current when all four inputs are applied to 5V, so when only one(1) input is applied to  5V, Idd becomes 380uA/4=95uA max.
  3. Appling 5V to one(1) input or all four inputs, the Idd is 380uA max. (Idd does not depend on the number of input applied to 5V.)

 

Regards,

Kazu
