Howdy,

A newbie here.

I am designing a 12bit DAC using Thin Film resistors. Current-out DAC, R2R ladder, Vdd=0->5V, Vref=0->10V. Has anyone on ythis board done one recently and if so what has the linearity been like? DNL and INL. Also what is max freq of operation (worst case).

Thanks in advance,
Dominic.
