I want to design an audio mixer. The audio signal comes from a phone connectoran audio jack and is then buffered by an op amp. I want to have an LED that indicates whether the signal is close to saturation for this op amp.
I have a voltage divider that gives me the comp
reference at 75% between V-
and V+
.
Will the following circuit work for my use case? Do I need to add a diode to act as a peak detector?
