Cxab4120 is a fully differential input stereo audio power amplifier, which can provide 3W continuous effective power for 3Ω load The built-in DC volume control module allows free conversion between bridge

Its high integration is conducive to reducing peripheral devices of notebook computer and palmtop computer. The volume of the bridge mode is controlled by the volume DC voltage, the difference between the single end volume and the bridge mode volume is controlled by the sediff voltage, and the semax voltage controls the maximum volume of the headset when the bridge mode is converted to the single end mode.

Product introduction

一,产品概述(General Description)         uYm嘉泰姆


        CXAB4120是一款全差分输入立体声音频功率放大器,能够为3Ω负载提供3W连续有效功率,内置直流音量控制模块,允许桥接模式(扬声器)和单端模式(耳机)间自由转换,其高集成度有利于笔记本电脑和掌上电脑减少外围器件。桥接模式音量由VOLUME直流电压控制,单端音量同桥接模式音量之差由SEDIFF电压控制,SEMAX电压控制桥接模式向单端模式转换时耳机的最大音量。渐变控制模式保证在正常工作和关断状态转换时输出变化的平滑过渡。uYm嘉泰姆
