amplifier, and an electronic volume circuit, making this IC ideal for LCD TVs and notebook computers.
•Applications
LCD TVs, notebook computers, and wordprocessors,
etc.
•Features
1) Internal stereo headphone amplifier that allows for
mixed input, along with a BTL monaural speaker
amplifier.
2) Internal anti-pop circuit, which prevents popping
sounds when the power is turned on.
3) Internal electronic volume and mute circuit.
4) Low-voltage operation (3.3V).
5) Internal input switch that also allows for the input of
computer beeps.
