Overview
AN12943A is an one-chip IC for the stereo speakers which can output
1 W by 8
, headphone amplifiers, line amplifiers and electronic
volumes.
Since the headphone amplifier is a dual power supply system which
uses a DC-DC converter to create the negative power source, an output
capacitor is not necessary.
Also the AN12943A is built-in power saving on/off function
automatically detecting input signal to save the power of speaker
amplifier.
