How fast can ADG4612 can turn on and off

Hi Khai,

Can I confirm what you are trying to do here.  Sounds like you want to input some kind of analog signal into the switch and then toggle the switch at 1MHz and chop it up?  The only measurement setup we have was used for the Ton/Toff results and is on the data sheet, timed as in figure 25.  I will see if I can find the original evaluation data for you and if it has more detail on the rise time.  If you need really fast switching speeds I would say have a look at the ADG702 or ADG802 (high power handling) families of parts, they have low Ton times. 

btw, there is an inexpensive evaluation board available for the ADG4612.  EVAL-ADG4612EBZ

Regards,

Eric.
