Hello all, new to this forum, hope I’ve posted in the right section.
I'm building a wired Volume Control for my DAC and need some help on what parts/components I will need.
Currently the DAC volume is controlled by a 3 Pin Mechanical 10k Potentiometer (turn knob style).
It’s really simple on how it operates, the Mechanical Potentiometer takes +3.3v and GROUND from the DAC, the Potentiometer position determines on what Voltage is Outputted, this in turn puts the DAC’s Volume UP or DOWN.
Current Mechanical 10k Potentiometer
- INPUT: +3.3v VOLTAGE
- GROUND
- OUTPUT: VARIABLE (up to 3.3v MAX) depending on the current Mechanical Potentiometer position)
Proposed Digital Potentiometer Control:
- 2 Push To Make Buttons: UP and DOWN.
- INPUT: +3.3v VOLTAGE
- GROUND
- OUTPUT: VARIABLE (up to 3.3v MAX) depending on the Digital Potentiometer position)
If possible I’d like the Volume to adjusted Logarithmically with a Maximum of 32 Steps.
I don’t need any computer control modules/interfaces etc as this is a stand alone Volume Control so need it to be really simple, hopefully someone can point me in the right direction.
