ANALOG CHARACTERISTICS (Continued)
(See Notes 1 and 2.)
Notes: 5. See the section of the data sheet which discusses input models.
6. Input current on VREF+ or VREF- may increase to 250 nA if operated within 50 mV of VA+ or VA-. This
is due to the rough charge buffer being saturated under these conditions.
