illustrate

LM4982是一个引用,可变增益音频功率放大器能够提供连续平均功率为16 80MW地面 单端负载的THD + N小于1%,从3V电源。 I2 C音量控制允许18到-76 dB的增益设置。

LM4982采用先进的电荷泵技术,产生的LM4982负电源电压。 This eliminates the need for output coupling capacitors typically used for single-ended loads.

IntelliSense是一个新的电路技术,使LM4982检测单声道或立体声耳机插头是否已插入到输出插孔。

Boomer audio power amplifiers are designed to provide high quality output power with very few external components. 的LM4982并不需要输出耦合电容器或启动电容器,因此非常适合用于手机和其他低电压应用,其中最低的功耗是一个主要的要求。

LM4982采用可选择的低功耗的停机和渠道选择的模式。

LM4982包含先进的POP和点击消除噪音电路,否则就会发生在开启和关闭转换。
