ADA4853/ADA4430 "disable" pin


 We have both ADA4853-1 and ADA4430-1 on our board.

in some scenario it can get a 3.3V in the "disable" pin while no voltage applied to the supply (Vs).There are no details in the datasheet (in the A.M.R section ) referes to this case.

can it cause to damage to the part?

what is the maximum allowed current through the 3.3V, in this case?



  • Hi Adiel,

    Sorry for the late reply. Can you provide your test set-up and schematic of your circuit. It seems impossible to measure a voltage when there is no active power supply connected to your circuit. Let me see the bigger picture of your set-up and analyze why you are measuring such voltage.
