Could you provide the output impedance of the HPROUTx and LEFT_LOX_X while AIC34 CODEC is enabled and disabled?
We do not provide output impedance of the Headphone or Line pins.
We specify output voltage and Load. for example for single ended Headphone output Vo=0.7vrms and RL=16 Ohm.
This corresponds to a Po=0.7*0.7/16 or 30 mw. Th driving impedance is low and can easily provide 0.7v for Loads down to 16 ohms.
On increasing load current well beyond 0.7/16 the amplifiers current limit and show short circuit flag.
