Temperature range is as follows: B Version: −40°C to +105°C.
See the Terminology section.
DC specifications tested with the outputs unloaded.
Linearity is tested using a reduced code range: AD5301 (Code 7 to 250); AD5311 (Code 28 to 1000); and AD5321 (Code 112 to 4000).
Guaranteed by design and characterization, not production tested.
Input filtering on both the SCL and SDA inputs suppress noise spikes that are less than 50 ns.
