Overview
The AN
12941
A is an amplifier IC for stereo
speakers which can output
1
W by
8
or
2
W by
4
.
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, AN
12941
A
has a built-in function which automatically detects the
input signal and can automatically enter power save
mode when there is no signal.

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).
