Hello,
I want to increase or decrease the volume of my circuit digitally. So anyone can suggest me which technique I can use for that. If anyone knows any digital pot which works on low power please help me in that also.
All 'digital pots' are low power or even statically powered so their consumption is very low (usually uA).
Bear in mind you have to digitally drive the pot somehow so choose one that is suitable for your driving circuit.
