So, use MacGman idea ...
a 2N7000 or 7002 will do it !!!
BTW ... which is the OPA supply voltage ??? ...

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Yes, most digital logic outputs are not purely ground. The are guaranteed to be within a certain range close to 0, usually 0.2 v which is typical VCE of a saturated transitor. For your application, the lowest Rds FET you can find would work best. Also make sure it can be controlled by a 5VDC signal. Like a BSS138LT or Si4410BDY or IRLL014N.
