Temperature range is −40°C to +125°C, typical at 25°C.
A grade offered in AD5064 only.
Linearity and total unadjusted error are calculated using a reduced code range—AD5064/AD5064-1: Code 512 to Code 65,024; AD5044: Code 128 to Code 16,256;
AD5024: Code 32 to Code 4064. Output unloaded.
See the Terminology section.
