1 All supplies can be varied ±5% and operation is guaranteed. Device is tested with AVDD = 4.75 V.

2 For single-supply operation (VREFN = 0 V, AVSS = 0 V), due to internal offset errors, INL and DNL are measured beginning at code 0x005.

3 Guaranteed by design and characterization, not production tested.

4 Operation is guaranteed over this reference range, but linearity is neither tested nor guaranteed.
