Headphone Amplifier Efficiency
The architecture of the headphone amplifier is that of typical class AB amplifiers. Test conditions (unless
otherwise specified): Input test signal is a 997 Hz sine wave; Power Consumption Mode 6 - Stereo Playback
w/16 Ω load. HP_GAIN = 1.1430. Best efficiency is realized when the amplifier outputs maximum power.
VA_HP = VA = 1.8 V
