Can I use a digital-to-analogue converter IC as a programmable attenuator?

if I feed an analogue signal into the reference input of a DAC, can I use the latter as a sort of electronic potentiometer by varying the digital inputs? Or do they respond too slowly to work in this way?
***** EDIT *****
@ultimate: Because I already have some DAC ICs in my parts drawer.

The idea works

You need to know all the specs of the DAC, etc.
