AN12941A Datasheet | Panasonic

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 - 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). - Operating supply voltage: VCC 3.0 V to 5.5 V/ VCC_SP 3.0 V to 5.5 V (0.25) 0.20±0.05 0.10 M Seating plane 0.10±0.10 (1.00) 1.20 max. 0° to 8° 0.50±0.10 HSOP056-P-0300A (Lead-free package) - Applications - Notebook PC, LCD monitor with speaker - Block Diagram Signal automatic detection SW Audio signal detection sensitivity SW SP power save SW Main signal mute SW Standby SW AGC on level SW AGC SW Input1 Input2 Input3 Input4 Automatic detection Automatic power save Mix circuit 4 Ω to 8 Ω Speaker...
