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