一般说明：MAX97220AETE+T
MAX97220AETE+T_是差分输入DirectDrive®线驱动器/耳机放大器。该设备能够将3VRMS的驱动线路电平负载转换为5V的1kI电源和2VRMS从3.3V电源转换为600I负载。一个耳机负载能够以125mW驱动用5V电源转换成32I。该IC具有内部固定的6dB增益或通过外部设置的增益外部电阻。外部增益设置节点可以也可用于为机顶盒应用配置过滤器。该IC在整个音频方面具有出色的THD + N带宽。提供两种版本的IC，它们具有不同的开启时间（tON）。耳机的A，C和E版本应用程序的tON为5.5ms，而B和D适用于机顶盒应用程序的版本具有130ms tON。片上电荷泵将电源输入反相，从而产生负电源轨。输出阶段放大器在正输入电源和电荷泵的输出之间供电。双极性电源将输出偏置在地附近，从而消除了需求用于引入失真的大型输出耦合电容器。 IC通电和断电，不会发出喀嗒声。该IC的尺寸为3mm x 3mm x 0.8mm，16引脚TQFN，在扩展的-40NC至+ 85NC上指定温度范围。
