AmplifierCircuits

Overview: The AN12941A is an amplifier IC for stereo  speakers which can output 1 W by 8 Ω or 2 W by 4 Ω.  The AGC circuit is built-in to prevent the resonance  or the vibration by the speaker's energy and the   clipping distortion what is called "broken up sound."  of the speakers. Also, to reduce power consumption, AN12941A  has a built-in function which automatically detects the  input signal and can automatically enter power save  mode when there is no signal. Features: Speaker amplifier is 1 W × 2-channel: 8 Ω, VCC = 5 V or 2 W × 2-channel: 4 Ω, VCC = 5 V Built-in AGC circuit  Prevention of the resonance or the vibration by  the speaker's energy and the clipping distortion  of the speaker by AGC at excessive input signal  (with AGC on/off switch). Built-in automatic power saving function  It detects input signals and switches on/off (with  the on/off switch for the automatic power saving). Ope...
