AN12942B
Audio signal processing IC for notebook PC
Overview
AN12942B is an one-chip IC for the stereo speakers which can output 1 W by 8
, headphone amplifiers, line amplifiers, and
electronic volumes.
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".
Also the AN12942B is built-in power saving on/off function automatically detecting input signal to save the power of speaker
amplifier.
