¡Hello everyone!.

Im trying to connect a potentiometer to MCP4725 (DAC) to modulate the amplitude and the frequency but i dont know how to continue. I will attach photos of my progress here. I intend to use 2 potentiometers.





My DAC is working to 5 bits of resolution, i need to work 8 bits.

Thanks for your attention  :D

Hi,
Have you been asking this in this Spanish section of the Forum?

Hi,

No its the same question, on the spanish forum i ask about creation of an audiometer using a dac and here im asking about how to connect a dac with a potentiometer,.

How is a frequency related to the DAC?
Frequency of the sine wave, can be modified?

DrDiettrich

A wave can be output by a sequence of voltage levels. The number of levels and the update frequency determine the output frequency.
