AN12942B Datasheet Audio Signal Processor

Manufacturer: Panasonic

Overview: ICs for Audio mon Use 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 Ω, 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.

Key Features

  • r>.
  • Speaker amplifier 1 W × 2-channel: 8 Ω, VCC = 5 V.
  • Built-in AGC circuit Prevention of the resonance or the vibration due to the speaker and the clipping distortion 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 auto power saving).
  • Built-in headphone amplifier and line amplifier.
