Does the ADRF5021 have any internal pullup or pulldown resistor?
I don't see any mention of this in the datasheet, but if I missed it please point it out to me.
Want to verify if its ok to leave pin floating (only in case of pulldown resistor, otherwise switch would always be off) or if it must be driven externally.
Referencing datasheet here:
Wanted to reply to this for visibility to ask if anyone had an answer to the above question or could point out if this information is available and I have missed it.
Just wanted to ask about this again for visibility.
The pin interface schematics can be found on page 6 of the datasheet.
The EN pin doesn't have pull-up or pull-down resistors. They need to be driven externally. We do not recommend leaving them floating.
