Help me regarding very low Supply Ripple output noise DC volume control unit
Can anyone help me with links,datasheets or schematics related to a highly eficient(very low supply ripple output noise)DC volume control ic,or maybe a transistor or hybrid(transistor+IC) dc volume control unit?
I've already tried several ic's but the Supply ripple noise turned out to be "consistent"(regardless of the fact that the power supply's transformer was toroidal(low noise) and the DC caps were over 6800uF.... So,no TDA8196,8199,or those all-in-one controller ic's(dc volume+ballance+tone corrector)!!!! I would prefer a transistor based schematic or a hybrid one,if possible.... Thanx! May all your projects succeed!!
