The question about AD7606 (ANALOGDIVICE)

I have a question about AD7606(ANALOGDIVICE)

The REF IN / REF OUT question of the AD7606 and the questions are as follows

1. The minimum CAPACITOR value using REF IN / REF OUT is 100 nF on the DATA SHEET (PAGE 24).

    What is the maximum, not the minimum? (Capacitor value 10uF applicable)

2. The usage voltage of REF IN / REF OUT is shown to be 2.5V. What is the current capacity?

Thank you.
