1 All supplies can be varied ±5%, and operation is guaranteed. Device is tested with VDD = 4.75 V.
2 For single-supply operation only (VREFL = 0.0 V, VSS = 0.0 V). Due to internal offset errors, INL and DNL are measured beginning at 0x005.
3 Operation is guaranteed over this reference range, but linearity is neither tested nor guaranteed.
4 All parameters are guaranteed by design.
5 All input control signals are specified with tr = tf = 5 ns (10% to 90% of 5 V) and timed from a voltage level of 1.6 V.
