I want to generate a AC voltage to drive a resolver.And,I know the WaveDAC8 can generate a sine wave directly.But,it is DC voltage.Dose anyone have a idea to transform it to AC?

If you want output symmetrical to ground then just a cap
will accomplish that. If you need it buffered, then external
OpAmp / Buffer would be needed. A method of generating
a negative supply voltage for the external amp attached
shown using diodes. Or use a charge pump, depends on
load current requirements you have.
