yet another DAC

it seems the Spice Models do "Count" -- although this may seem a far shot -- then there is actually a real life analogy or at least a strong potential -- that the certain components or a combination of produces far better results than some others !!

perhaps continued ...

optimistic with "continuous"/slow slope signal

fuzzy science of extending the range of 3-terminal (fixed) voltage regulator

Bew , here we go  . . .

• in case of ringing inc C2 then C6 then (C8,C7)
• R10 , C8 (, R8) -- lobe ass filter
• R11 , R7 -- Vtg. Div.-r
• R13 , (R3 , R14) -- Regulation logic
• (R15 , R17) , (R18 , R19) -- fine tune level shift (enabled by R3 ≠ R14)
• /!\ There is no SC protection (use fuse or you'll loose your device) /!\

. . . it seems the "std." v. of the above has the same error of apx. ±400µV ---- so i added a secondary error correction

the remaining op amp from ´1366/-7 can be used in a separate supply for opamps or electrical-fuse for short circuit , e.c.

a Collector load (sc proof) Vtg. Regulator

since the component countfor this bullsh¡t

is higher and it has an error to the range
 of the following (! not built / tested -- but i guess it's not far from it´s actual)

then i guess i gonna get this 1 PCB-d and cased in with an appropriate ( 300+mA @ 10V DC ) transformer , damn it takes long to test out what you actually need and that actually works as designed -- should've brought a random 600÷1000mA 9V SC proof linear reg. such as KA7809

Update !

now more precise v. of the above is available
