Temperature range: B grade = −40°C to +105°C.
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.
Guaranteed by design and characterization, not production tested.
Interface inactive. All DACs active. DAC outputs unloaded.
Both DACs powered down.
Guaranteed by design and characterization, not production tested.
See the Terminology section.
Temperature range: B grade = −40°C to +105°C, typical at +25°C.
