[sdiy] Rail to rail Dacs

[Oren B. Leavitt]

Hello,

This means that the analog output voltage swing of the buffer amps can go all the
way to the + and - voltage of the power supply without distorting - It is simply
clipped flat when the maximum is reached. As opposed to amplifiers which tend to
distort non-linearly, or fold over, as the output voltage reaches a certain
percentage of the full power supply voltage.
