Power Dissipation
1
All supplies can be varied ±5% and operation is guaranteed. Device is tested with AVDD = 4.75 V.
2
For single-supply operation (V
REFN
= 0 V, AV
SS
= 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.
