3
DC specifications tested with the outputs unloaded unless stated otherwise.
4
Linearity is tested using a reduced code range: AD5308 (Code 8 to Code 255), AD5318 (Code 28 to Code 1023), and AD5328 (Code 115 to Code 4095).
5
This corresponds to x codes. x = deadband voltage/LSB size.
6
Guaranteed by design and characterization; not production tested.
7
For the amplifier output to reach its minimum voltage, offset error must be negative. For the amplifier output to reach its maximum voltage, V
REF
= V

and offset plus
gain error must be positive.
