That would be cool. Might be outside the scope of my current project. For that, it seems that the consensus is I shouldn't expect major start-up problems with the sorts of stages I am building. Of course, I'll try it on the test bench first.mediatechnology wrote:I was wondering if a low-power 5V standby voltage-powered op amp could be used as a comparator to detect signal presence and then bootstrap itself and the higher-current balanced input to +15V (and -15V) supply levels.
An input that powers itself down and provides a power on, mute output and/or signal fail indication is kind of neat and an interesting challenge.
Particularly the signal fail/silence sensor part.
Thanks. You've been very helpful.
