12.1 Supply decoupling
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.
If a DC-to-DC converter is used to supply regulator 3, the recommendations of the
converter manufacturer relating to decoupling must be followed.
