NOTES
1All supplies can be varied ± 5% and operation is guaranteed. Device is tested with VDD = +4.75 V.
2For single-supply operation (VVREFLO = 0 V, VSS = 0 V), due to internal offset errors INL and DNL are measured beginning at code 003H.
3Guaranteed but not tested.
4Operation is guaranteed over this reference range, but linearity is neither tested nor guaranteed.
5VOUT swing between +2.5 V and –2.5 V with VDD = 5.0 V.
6All 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.
7Typical values indicate performance measured at +25°C.
Specifications subject to change without notice.
