LM386 based stereo audio amplifier with digital volume ...
https://embedded-lab.com/blog/lm386-based-stereo-audio-amplifier-with-digital-volume-control/
LM386 audio amplifier circuit. The supply voltage range for LM386 is wide (4-18 V). It can be powered with a +9V PP3 battery. For digital volume control feature, we will replace the external 10K potentiometer at the input stage with a digital potentiometer chip. MAXIM’s DS1868 is a dual digital potentiometer chip.

Volume control for LM386 - Electrical Engineering Stack ...
https://electronics.stackexchange.com/questions/415936/volume-control-for-lm386
When I carefully dial it, I find a spot where I get clean audio (the 10k pot is then at ~ 500 Ω). This is the same with the ready-made breakout board that I used for comparison. Now the point of not using the ready made module was that I wanted to add a volume control. Apparently scaling V in is not how one supposed to do that. If I go up or ...

I am trying to use a digital potentiometer for volume control in a LM386 Amplifier circuit. I am using the LM386 amplifier with the above setup. The mechanical 10K pot has been replaced with a 10K AD5245 Digital linear pot. During testing the resistance value is scaled up from 0 to 255. The problem I am having is due to the potentiometer being linear, after the 5th or 6th tap the …
