596uA input bias current on LM6132?

[Jim Thompson]

thanks. this isnt how the opamp is actually used in the circuit. this
is how i wired it up to isolate the bias current paths.

FWIW, the spice model in circuitmaker does not show this behavior,
which made things even more confusing.

The model, that I found immediately, DOES show the speed-up devices.

I really doubt you even have a meter sensitive enough to measure anything
useful.
