AN12941A Description
ICs for Audio mon Use AN12941A Audio power IC for notebook PC 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...
