Hello all,
I came across a nice, simple circuit for a low distortion buffer that I'm thinking of using as a unity-gain headphone amp. I already have most of the parts in my bin, and it's straightforward enough for me to tackle.
My DAC output is pretty juicy, so I really don't need gain. I've attached the schematic below. What do you guys think of it?
The only thing I'm unsure of is what D1 and D2 represent. Are they constant current diodes? If so, what is the "2.0" likely to mean? Surely not amps
. Is the 47uF input coupling cap a bit much? From what I've read it doesn't need to be anywhere near that big.
