NOTES
1See Terminology.
2Temperature range is as follows: B Version: –40°C to +105°C.
3DC specifications tested with the outputs unloaded.
4Linearity is tested using a reduced code range: AD5301 (Code 7 to 250); AD5311 (Code 28 to 1000); and AD5321 (Code 112 to 4000).
5Guaranteed by design and characterization, not production tested.
6Input filtering on both the SCL and SDA inputs suppress noise spikes that are less than 50 ns.
Specifications subject to change without notice.
