Notes
1. All supply connections must be made to the same power supply unit.
2. When the supply voltages are below 2.7 V and the headphone load impedance is 16 Ω, it is recommended to limit
3. V
4. When higher capacitive loads must be driven, a 100 Ω resistor must be connected in series with the DAC output in
