ADA4896, ADA4897 input bias current direction.


In the datasheet of ADA4896/ADA4897 bias current is specified as -11uA (typ.). What "-" sign signifies? At first I assumed it signifies the direction of current flow as in "-" signifies current flowing out of the input pin and "+" signifies current flowing into the input pin. Can you please confirm that?

When I try to simulate bias current, the bias current flows into the input pin which is not what I expected. Could you also clarify that?
