1 Temperature range: B grade: −40°C to +105°C.

2 Linearity calculated using a reduced code range: AD5664R (Code 512 to Code 65,024); AD5644R (Code 128 to Code 16,256); AD5624R (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 All DACs powered down.
