AN12941A Datasheet Stereo Speaker Amplifier

Manufacturer: Panasonic

Overview: 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 automatically detects the input signal and can automatically enter power save mode when there is no signal. 14.00±0.10 (6.90) (5.45) 56 29 (2.25) (3.70) 6.10±0.10 8.10±0.20 Seating plane (1.00) 0.15±0.05 Area of no resin flash Unit: mm 0.

Key Features

  • r>.
  • 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).
  • Operating supply voltage: VCC 3.0 V to 5.5 V.
