1 For single supply operation only (VREFN = 0 V, AVSS = 0 V): Due to internal offset errors, INL and DNL are measured beginning at code 0x005.
2 Guaranteed by design and characterization, not production tested.
3 Operation is guaranteed over this reference range, but linearity is neither tested nor guaranteed.
