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:
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
Yes i found that too but these are non stock items, and since i'm under time constraints i typically click show only items on stock, then if i have issue with the part selection i go back and search little bit more removing some constraints (time consuming).
Regarding +-5V operation, that one is equivalent to 10VSS (single supply) so i would not take that one into account...
You can verify that by overlaying curves for 10SS and +-5, it is the same curve (and the same voltage between Vdd/Vss so it makes sense), check curve on the fig5, curve 0-10.8V . and fig4 (+-5.5V), it is pretty much the same curve on ADG1201 datasheet.
Thank you for the overview AN-874PDF.
