Notes:
5. 10 kΩ, 100 pF load. Headphone and Speaker outputs disabled.
6. 48 Ω, 100 pF load. For the headphone outputs, THD with 10kΩ, 100pF load is 0.02%.
7. Typically, 50% of the power supply current is supplied to the analog power pins (VA1, VA2)
and 50% is supplied to the digital power pins (VD1, VD2). Values given are for unloaded outputs.
