1 Temperature ranges are as follows: B Version: -40°C to +125°C, typical at 25°C.
2 Linearity calculated using a reduced code range of 485 to 64714. Output unloaded.
3DC specifications tested with the outputs unloaded unless stated otherwise.
4Linearity is tested using a reduced code range: AD5628 (Code 48 to Code 4047), AD5648 (Code / to Code /), and AD5668 (Code 485 to 64714).
6Guaranteed by design and characterization; not production tested.
8Interface inactive. All DACs active. DAC outputs unloaded.
9All eight DACs powered down.
Specifications subject to change without notice.
