ADG4612 output problem

Dear Madam/Sir,

I am using the ADG4612 switch in my design. I connect Vdd to 3.3v and Vss to 0v

However I am getting false outputs in those two cases:

- when enable is off and Vin > Vdd+Vt I get an output equal to Vin/2 while i should get nothing

- when enable is on and Vin < Vdd+Vt it works fine however when Vin is higher, I get the same behavior as in case one.

Could you please help me with that issue.

Thank you in advance.

  • Hi,

    Thank you for your quick answer.

    In fact that's what i was expecting.

    I have a capacitive load of 47pF and a resistive one of 400ohm.

    When enable is Off and Vin < Vdd I have no output => correct behavior.

    I have only tried it on one component but I am going to order new ones to do more tests.
