Filterless High Efficiency 1.1W Switching Audio Amplifier

General Description\nThe LM4664 is a fully integrated single-supply high efficiency switching audio amplifier. It features an innovative modulator that eliminates the LC output filter used with typical switching amplifiers. Eliminating the output filter reduces parts count, simplifies circuit design ■ No output filter required for inductive transducers\n■ Selectable gain of 6dB or 12dB\n■ Very fast turn on time: 7ms (typ)\n■ Minimum external components\n■ \"Click and pop\" suppression circuitry\n■ Micro-power shutdown mode\n■ Short circuit protection\n■ Available in space-saving micro SMD packa;
