oneliu, 16x34mm is super compact PCB for such huge IC as sa9123, good job! I hope the audio specs are also not too bad? I currently working on my project in the same form-factor "USB dongle" CM6642+ES9038Q2M+HPA 300mWx2ch balance outputs, and my PCB 20x46mm. Due to 600mW@32ohm of total power I have to keep all SMD parts on the top side, only 3000uF 6.3V on bottom side. Not sure if I can make my PCB smaller but I'll try, for that project priority #1 is THD+N(<.0005%@-3dbfs@hifiman he400i load@44.1kHz) and S/N(-126dbA@192kHz) performances, size is priority #2 ;) |
