I'm trying to build a triangle wave generator with the following characteristics:
I toyed with it for a while by tweaking the values of R5, R3 and R4, and while it does comply more or less with the frequency output that I want, its voltage output (minimum and maximum) never actually reaches zero, nor 5V. What's more, that range actually varies with frequency in both limits.
Is there a simple way to adjust this circuit for that purpose? Or would you recommend an entirely different approach?
- Single 5V supply
- Variable 120 Hz to 10 kHz output
- Fixed 0 - 5V range output, or as close as possible
