Hi!
Working on low power stereo amplifier built around TDA2822 chip. It has 2 sources: External source (audio in from RCA_1) and Internal from another digital part (C3 and C4 are decoupling capacitors for supply this part). Very simple project, but I have some questions before layout it:
1) About volume pots resistance (10K or 100K?) and the value of R5 and R6 (1K, 10K or nothing?)
2) I add C6 capacitor for better protection, so should I add some additional filters to make it work better.
3) Should I add some impedance resistors for the "internal digital audio source" (nets R_INTIN and L_INTIN).
4) And maybe I've missed something else?
