I am using TPA2005D1 class D amplifier IC, whenever I am turning ON the IC, while the volume is set to high, it is making loud thump and pop sound, then it goes away and works fine. But while the volume is set to low and then I turn ON the device, then is no thump and pop sound.
The line level input that I am giving to TPA2005D1 contains small DC offset, but I am using coupling capacitor to make offset zero. (Please find the schematic attached below)
After getting the response from the users I am finding two approaches to solve this problem.
Method 1: Can we connect 100K resistor between C15 and ground ; 100K between C16 and ground, so that there is no buildup of charge in the capacitor as to reduce the pop sound in the first place.
We can delay the start of the TPA2005D1 using RC circuit in the shutdown pin, so that pop sound will be eliminated.
Should I do Method 1 or Method 2?
