Ok I will order some chips “digital pots” from microchip, and I want SMD chips- because i am good in soldering - and I see only positve things by SMD.
Thats Right? :
SOIC = SMD
PDIP = BIG like optocopler
What meens by the SMDs: I/SN and E/SN
What meens by the PDIPS: I/P and E/P (my pic18 is a I/P 
but whats this meen)
for example: MCP41100-I/SN
And what type I need for the Mios project SOIC, I/SN (PDIP I/P) - or better what type could work?
And want anybody digi pots in austria or germany too? because this:
1-25 1.21eurons
26-99 0.86 eurons this are 35 cents per piece!!! :o
And anybody has some experience with the pots?
