Tool/software:
OPA2991 as comparator with V+=+5V V- = -5V In+ =2.5V , In- =0 V,The Out 4.99V work, but The In- Pin has hundred uA current if ground to 0V, ref to datasheet the input current should be low more than this.

Hello Tom, welcome to the e2e forums.
Make sure pin 4 is really -5V and not accidently disconnected. If pin 4 is open then the lowest voltage pin will try to take pin4's place.
If IN- is greater than 2.5V, what is the pin current and output voltage?
