Hi, I built this peak detector circuit here:
http://macetech.com/vuinput01big.png
VCC is 5 volts
I used a lm324, and instead of the 1uf cap I used a .68uf cap. I used two 4148 diodes as they werent labeled on the schematic.
The audio in is from a MP3 player. With the mp3 player at max volume, the voltage peaks out at about 2.4 volts. Why is this? How can I fix it so the range is higher like in the picture?
