,产品概述(General Description)         
      The  jtm4808 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16Ω load with 0.1% (THD+N) from a 5V power supply.
audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since
the jtm4808 does not require bootstrap capacitors or snub-ber networks, it is optimally suited for low-power portable systems.The unity-gain stable gain-setting resistors.808 can be configured by external

我司的JTM4871/SOP8/3W有如下<a href="http://www.jtm-ic.com/a/xinwenzhongxin/xinpinjishu/" target="_blank" style="padding: 0px; margin: 0px; color: rgb(37, 110, 177); text-decoration: none;">优点:</td>







1.工作电压2.0-5.5V,耐压6V








2.输出功率可以达3W/3OJTM和2.5W/4OJTM






3.没有交越失真的问题</td>








4.音质比较好,音量比较大,音质/音量可以和CSC8002媲美。</td>
