DAC turbo (Off Topic)

Hi Klaus,

Its all about the batteries ESR. I'd guess that your battery still
has 20-30mR ESR.

No idea of its ESR. It has a specified internal resistance of 9mR, but that will be DC, I guess.

Unfortunately it seems that one needs a real big battery to get that far
down. But I figured that every mR counts on the supply rail.
Without switch and connector it was perfect. The pity is - there is no
way
around these you have to have them in! It is just do dangerous without
switch and connector.

Yes, I see the difficulty. So what difference in ESR does adding your best switch and connector make?

I am buffering with 8*470uF + 0,2uf (BG NONpolars) and a 1000pF ceramic
(0805 Type with silver leads - DIY).

Thanks. I guess I have some room for improvement here too.

Best regards
Steve
