Note 2:
In single-supply operation, INL and GE calculated from Code 11 to Code 4095. Tested at V
DD
= 5V.
Note 3:
This specification applies to both gain error power-supply rejection ratio and offset error power-supply rejection ratio.
Note 4:
Guaranteed by design.
Note 5:
Tested at I
OUT
= 100μA. The reference can typically source up to 5mA (see Typical Operating Characteristics).
