1
Temperature range: 40°C to +85°C; typical at +25°C.
2
For 0 mA to 20 mA and 0 mA to 24 mA ranges, INL is measured from Code 256 for the AD5420 and Code 16 for the AD5410.
3
Guaranteed by design and characterization but not production tested.
4
The on-chip reference is production trimmed and tested at 25°C and 85°C. It is characterized from 40°C to +85°C.
