Hi,
I have an op-amp circuit with two LM324's, one to combine the analog (stereo audio) signal, and the second to amplify to ~0.8v.
The next stage is a TLC339 comparator, which has an output of ~1.2, but the expected output is 5v when the signal is over the 0.25v
set point.
I am new to mixed signal design, and any help would be appreciated.
