dddac output cap question | diyAudio

The DDDAC has a few volts on it's output (I built one a while back, but can't remember the figure). The only issue with the buffer is whether it will clip, but with a voltage supply greater than that of the DDDAC itself (e.g. at least +/- 9V) you'll be fine.

The R2R Buffer PCB design is a little different from the first ones used on the DDDAC, but it is still a JFET Buffer with Cascoded JFET CCS at heart. It is dual mono with voltage reference circuits for both sides. All transistors and some capacitors are SMT. The outputs are capacitor coupled.
