no, I'm talking about Vref input bandwidth, specified in Vref section of 
datasheet


> I'm talking about the specs for the Vref input pin. Those are often designed to reject noise on the reference voltage. Some chips even have an extra pin for a large capacitor to filter Vref. Others have an internal filter or both internal and external. In other words, the bandwidth is completely unrelated to the DAC signal output.

then we probably talk about totally different kind of ICs

what does it have to do with DAC?
