Temperature range: A grade and B grade are both equal to −40°C to +105°C.
2
Linearty calculated using a reduced code range: AD5663 (Code 512 to Code 65024). Output unloaded.
3
Guaranteed by design and characterization, not production tested.
4
Interface inactive. All DACs active. DAC outputs unloaded.
5
Both DACs powered down.
