如今,以平衡方式或差分方式驱动的音频线路可以在接近1000英尺的距离内传送高质量的信号已经不是什么新鲜事了。下面要做的只是能不能用一颗集成电路(IC)来完成这一功能,以取代传统的又大又笨,而且价格又贵的变压器。 音频平衡线路驱动器——或者差分线路驱动器——是对普通差分放大器的补充。不过,有一点要注意的是,线路驱动器的差分输出所介绍的起到描述性作用的参数以及芯片连接形式不适用于其他任何装置。器件模型 Nowadays, it is not new that audio lines driven in a balanced or differential way can transmit high-quality signals at distances of up to 1,000 feet. The next thing to do is to use an integrated circuit (IC) to accomplish this function, to replace the traditional large and stupid, and expensive transformers. Audio balanced line driver - or differential line driver - is a supplement to a normal differential amplifier. However, it is important to note that the descriptive effect of the parameters introduced by the differential outputs of the line driver, as well as the chip connections, do not apply to any other device.
