1 For specified performance, headroom requirement is 0.9 V.
2 INL is the relative accuracy. It is measured from Code 512, Code 128, Code 32 for the AD5754R, AD5734R, AD5724R respectively.
3 Guaranteed by characterization; 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.
