Typical Characteristics (Stereo BTL Mode): f_{SPK_AMP} = 384 kHz (continued)
At T_A = 25°C, f_{SPK_AMP} = 384 kHz, input signal is 1 kHz Sine, unless otherwise noted. Filter used for 8 Ω = 22 µH + 0.68 µF,
Filter used for 6 Ω = 15 µH + 0.68 µF, Filter used for 4 Ω = 10 µH + 0.68 µF unless otherwise noted.
