(07-23-2023, 10:27 AM)ronovar Wrote: Panasonic FR i FM pa i drugi elektroliti idu istog diametra i rastera tako da tu nema problema...

Precrtana shema u EAGLE, stavio sam umjesto 10uF na bazama DB 100uF neka se nadje a i diameter je 6,3mm naspram malih 5,0mm elektrolita....

Za IC sam stavio kako je Braca sugerirao single opampa OPA828ID posto je taj jedini u SOIC8 kucistu a da ga mozemo zalemiti na adapter SOIC8 na DIL8 jer footprint na PCB ce biti DIL8.

Evo sheme i 3D preview da vidimo dali sam dobro pozicionirao izlazne TO-126 Toshibe...

A 1uF je MKT tipa nije MKP pa valjda nece da pokvari performanse....jer MKP su ogromni na 1uF......to je OVAJ!

Q1 a na njega Q4
Q2 i na njega Q3
-> to je OK
Lepo slagaš kockice!!!

C7 1uF je u biasu strujnog ogledala na load strani, tu nismo uopšte kritični, može MKT!
C8 je preko napajanja opampa, tu se več trebate posavetovati izmedju ko šta inače tu postavlja. Može i manje od 1uF, 100nF...1uF
