I need help with class d amplifier: ssm3302. I've build a prototype board with this amplifier. Every turning off and on ssm3302 using sdnl and sdnr causes a very bad click effect on speakers.

The audio input is connected with uda1330 dac, output speakers are 4ohm 5W, input voltage 12v.


Here is a schematic of audio and power block (please use it only for your reference):

Any help and sugestions will be apreciated.


Best regards,
