1
Typical values indicate performance measured at 25°C.
2
All supplies can be varied ±5% and operation is guaranteed. Device is tested with V
DD
= 4.75 V.
3
For single-supply operation (V
VREFLO
= 0 V, V
SS
= 0 V), due to internal offset errors INL and DNL are measured beginning at Code 0x005.
4
Guaranteed, but not tested.
5
Operation is guaranteed over this reference range, but linearity is neither tested nor guaranteed.
6
V
OUT
swing between +2.5 V and −2.5 V with V
DD
= 5.0 V.
7
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.
