Temperature range is −40°C to +125°C, typical at 25°C.
A grade offered in AD5065 only.
Linearity calculated using a reduced code range—AD5065: Code 512 to Code 65,024; AD5045: Code 128 to Code 16,256; AD5025: Code 32 to Code 4064. Output
unloaded.
Guaranteed by design and characterization; not production tested.
Current flowing into or out of individual digital pins.
Interface inactive. All DACs active. DAC outputs unloaded.
Both DACs powered down.
Guaranteed by design and characterization; not production tested.
Temperature range is −40°C to + 125°C, typical at 25°C.
