Temperature range is −40°C to +105°C, typical at 25°C.
2
Linearity calculated using a reduced code range of AD5678 12-bit DACs (Code 32 to Code 4,064) and AD5678 16-bit DACs (Code 512 to Code 65,024). Output
unloaded.
3
Guaranteed by design and characterization; not production tested.
4
Interface inactive. All DACs active. DAC outputs unloaded.
5
All eight DACs powered down.
