Temperature range: A, B grade = −40°C to +105°C.
2
Linearity calculated using a reduced code range: AD5663R (Code 512 to Code 65,024), AD5643R (Code 128 to Code 16,256), and AD5623R (Code 32 to Code 4064).
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.
