Signal Generator - Working Diagram?
« on: July 30, 2019, 02:40:38 pm »
Can anyone verify if this is a working diagram?

Here's a simpler op-amp function generator circuit that you might find helpful:

Yes, design will work quite well up to a few kHz.

Yes, that will also work. The big downside is the amplitude of the triangle and sine wave outputs will vary, depending on the frequency setting.

One way to overcome this issue is to use a triangle wave generator and a triangle-to-sine converter circuit. See the thread linked below:
