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

).
