1 Temperature range: −40°C to +105°C; typical at +25°C.

2 When the AD5412/AD5422 is powered with AVSS = 0 V, INL for the 0 V to 5.5 V and 0 V to 11 V ranges is measured beginning from Code 256 for the AD5422 and Code

16 for the AD5412.

3 Guaranteed by design and characterization; not production tested.
