    Hello Arthur,

    I just looked one detail, we always recommend to add a decoupling capacitor of 0.1uF. This capacitor helps with higher frequency transients, spikes or digital hash on the line. You could refer the Decoupling Capacitors section of the amplifier's datasheet to find further information.
