... MM1434 appears in the 10 terminal. When the power supply of MM1434 is switched off, the pop noise occur. We recommend muting the pop noise. The way is that the power supply of MM1434 is switched off after the power supply of the follow power amplifier is switched off. Note recommend using the regulator for the power supply which occurs the ripple. ...
