I recently have a question about the PCM1795 decoupling caps, about the recommended 47uf electrolytic cap between Vcc1(pin23) & VcomL(pin22) and between Vcc1 & VcomR(pin21), what's its function? Is it serve as simple power supply decoupling? (Are pin22 & pin21 internally connected to analog ground?)
If so, can I use larger capacitor here? (I don't know whether the "internal bias decoupling pin" serve as some special functions.)
