Temperature range is −40°C to +105°C, typical at 25°C.
Linearity calculated using a reduced code range of AD5628 (Code 32 to Code 4064), AD5648 (Code 128 to Code 16256), and AD5668 (Code 512 to 65024). Output
unloaded.
Guaranteed by design and characterization; not production tested.
Interface inactive. All DACs active. DAC outputs unloaded.
All eight DACs powered down.
Guaranteed by design and characterization; not production tested.
See the Terminology section.
Temperature range is −40°C to +105°C, typical at 25°C.
