I'm working on the audio amplifier for my portable N64. Currently, I'm experimenting with this PAM8403, and have made it drive some 8 Ohm speakers I had laying around. I would like to integrate a headphone jack that disconnects the speakers when plugged in. I am experimenting with this headphone jack switch . I can get it to disconnect the speakers, but one headphone speaker is weaker than the other and both are greatly distorted compared to the speakers. I suspect that is is because the PAM8403 isn't designed for 32 Ohm headphones, or I need some coupling capacitors or similar. Any thoughts? Are any of you using other/better solutions to add a speaker and headphone switch option? EG: TDA2822M, PAM8009, so on. I've been looking for a complete solution (1-3W, vol control via thumbwheel, speaker out port, headphone out jack) that I can just drop in, but can't find any yet. Thank you for your help and pro tips!
