Features

2-cannels BTL power amplifier built-in : Standard output power = 1.2W (VCC = 5V, RL = 8Ω, THD = 10%) Output coupling capacitor is unnecessary because of differential output type.
Volume function built-in (variable range: 69dB standard), DC voltage control system.
Mute function built-in (shared with VOL-min).
Standby function built-in (three-value control ⇒ Shared with the second amplifier stop control pin) : Standard standby current = 0.01μA (VCC = 5V).
