详细描述

UTC MC34119 是一款低功耗音频放大器 IC，适用于电话应用，例如免提电话。它提供差分扬声器输出，以在低电源电压下最大化输出摆幅，并且不需要额外的冷却电容器。

开环增益为 80dB，而闭环增益由两个外部电阻设置。静音引脚允许关闭和/或静音输入信号。

The UTC MC34119 is a low power audio amplifier IC intended for telephone applications, such as speakerphones. It provides differential speaker outputs to maximize output swing at low supply voltages and additional cooling capacitors are not required.

Open loop gain is 80dB, while closed loop gain is set with two external resistors. The Mute pin permits powering down and/or muting the input signal.
