AD8391集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

AD8391属于集成电路（IC）的驱动器接收器收发器。由亚德诺半导体技术有限公司制造生产的AD8391驱动器，接收器，收发器该系列产品的主要功能是提供必需的硬件资源，以通过延长电缆或印制线进行通信。确切的功能会因所采用的通信协议而异，可能包括诸如瞬态抑制之类的功能，这些功能对于通信用途可能并非绝对必要，但对于可能的使用环境却是明智之选。

PRODUCT DESCRIPTION

The AD8391 consists of two parallel, low cost xDSL line drive amplifiers capable of driving low distortion signals while running on both 3 V to 12 V single-supply or equivalent dual-supply rails. It is primarily intended for use in single-supply xDSL systems where low power is essential, such as line powered and battery backup systems. Each amplifier output drives more than 250 mA of current while maintaining –82 dBc of SFDR at 100 kHz on 12 V, outstanding performance for any xDSL CPE application.
