So i built this amp using the bridged schematic from the datasheet. The amp itself works fine if i run wires to it from an audio sorce (ipod computer ect.). But the original use of this amp is to amplify the sound coming from a bluetooth headset. I'm using a jabra bluetooth that plays music alog with the usual phone functions. when i connect the bluetooth to the amp i get some kind of interference. The only way i can describe it is that i can hear the bluetooth working. When it is connected but not playing any audio it's quiet, but when i play music or make a phone call I get all sorts of clicking and buzzing. Is there any way i can keep this from happening? I have double checked my pcb and still cant figure it out. any help would be greatly appreciated.
