Supply decoupling
(see Fig.28)
The high frequency 220 nF decoupling capacitors connected to power supply voltage pins 6 and 20 should be located
as close as possible to these pins.
It is important to use good quality capacitors. These capacitors should be able to suppress high voltage peaks that can
occur on the power supply if several audio channels are accidentally shorted to the power supply simultaneously, due to
the activation of current protection. Good results have been achieved using 0805 case-size capacitors (X7R material,
220 nF) located close to power supply voltage pins 6 and 20.
