LM4897 1.1 Watt Audio Power Amplifier with Fade-In and Fade-Out May 2003 LM4897 1.1 Watt Audio Power Amplifier with Fade-In and Fade-Out General Description The LM4897 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable munication device applications. It is capable of delivering 1.1W of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a +5VDC power supply. The LM4897 contains advanced pop and click circuitry that eliminate noises which would otherwise occur during turn-on and turn-off transitions. It also contains a fade-in/fade-out feature that eliminates unnatural sound generated by...
