AP4890B Overview
The AP4890B is an audio power amplifier designed for portable munication device applications such as mobile phone applications. The AP4890B is capable of delivering 1W of continuous average power to an 8Ω BTL and with less than 1% distortion (THD+N) from a 5.0V power supply, and 350mW to a 8Ω BTL load from a 3V power supply. The AP4890B provides high quality audio while requiring few extemal ponents and minimal...
