Hi, since this is my first post on analog devices forum, I would like to introduce myself.
My name is Robert and i work at Michigan state university.
I am designing integrating type of light detector so i decided to use bilateral switch to reset integrating capacitor.
Now i sourced out bunch of small cmos bilateral switches and tried a lot of them, best performance regarding lowest charge injection I experienced is with ADG442.
Now since this device i'm making is really small (handheld) i prefer small case (as small as possible) so SO16 that is smallest case in which this switch is supplied will not cut in (plus i do not have a need for 3 remaining switches so they are unnecessary ballast in my case).
My question is:
Is there small case (SOT23-6 or smaller), single switch version of ADG442 or equivalent switch that would include:
- Small charge injection ( <3pC)
- low leakage current
Both of these parameters come from trench insulation i believe, so any device sharing same technology in really small case will do for me.
I source my components over Digikey parametric search, but Qi is not one of parameters that Digikey offers in their search filter options.
Also any other solutions is welcomed.
Regards
Robert
