ADG904 DC handling

Hi

I know the ADG904 can handle a DC bias of 0.5V, however I'd like to clarify something: can the switch actually pass DC from one port to the common port?

E.g. if I inject 0.1V DC to RF1, will I get 0.1V DC on RFC?

Thank you for your help

  • Hi Yann,  yes no problem, you will see the voltage through the part.  You can think of the switch when it is on as a series resistor.  The On resistance will be somewhere around 12ohms so depending how you are driving your signal you may want to consider an IR drop.
