For one of my projects, I need to design a triangle wave generator. What I was thinking to do is to use an adjustable linear voltage regulator (i.e LM117 or LT317) and use a digital potentiometer at the adj pin to change the resistance. Afterwards, i will use a microcontroller to change the steps very quickly. I am hoping that this will create a relatively good triangle wave. The main issue that I am faced with is that my Digital Pot is only capable of handling 5 Ma's and the current flowing through it is approximately 5.5 Ma's. I know this is probably not the best way to proceed in order to design a signal generator but since I am on a tight time constraint, this was the only idea that I could think of.
If anyone has any suggestions in order to improve my idea or suggestions concerning other components that I could use in order to bring down the current flowing through the pot, it would be greatly appreciated.
Thanks
