ad5323 using as programmable attenuator

1. I supposed to use 'REF' as input pin. Also, the noise of this input signal is already known. However, I don't see any information about how much noise this DAC may contribute. So I want to know does this mean DAC won't contribute any noise or how can I calculate this noise.

 

2. I have noticed that most of your DAC chips are based on the principle of resistance net according to datasheet. Do you have any charge redistribution DAC? Cause I think capacitor would have better noise performance than resistance.
