I believe he meant to say that they AREN'T good enough for higher
voltages.

I haven't looked recently, but when I did most MChip op-amps (and analog
parts in general) worked up to a max of around 6V. This is due to the
fact that they are basically using the processes they use for their
digital parts for their analog parts.

For some 6V is fine, for many, it's not. Personally much of my analog
stuff in the past has been above 6V (usually something like split rail
-5V -> 5V, or single rail but higher then 6V supply).

These days more and more of my analog is < 6V, so MChip parts can enter
the stage a little more often, at least for me.
