AC measurement circuit question

<< < (5/5)

Tom18991:
Ian, your LT1716 circuit works like a champ.  I fed it signals from a function generator and noticed a few things I'm not sure I understand.  For ease, I set the voltage divider to 2.5 volts (two 3.3k resistors) and verified nearly exactly 2.5v.  When I fed it a triangle wave, it wouldn't trigger until I got closer to 5.6v or so.  Switching to a sine was brought that down a bit to maybe 5.4 or 5.5.  I would have thought anything over 5v peak to peak (i.e. 2.5v above 0) would have triggered it.  What am I missing?
