AD8145: 差分放大器
AD8145是一款三路、低成本、差分至单端接收器，专为通过双绞线电缆或差分印刷电路板迹线接收红绿蓝(RGB)视频信号而设计，也可用于接收任何类型的模拟信号或进行高速数据传输，还内置两个具有迟滞特性的辅助比较器，可以用来解码在接收共模电压下编码的视频同步信号，以便接收数字信号，或用作通用型比较器。
The AD8145 is a triple, low cost, differential-to-single-ended receiver specifically designed for receiving red-green-blue (RGB) video signals over twisted pair cable or differential printed circuit board traces. It can also be used to receive any type of analog signal or high speed data transmission. Two auxiliary comparators with hysteresis are provided that can be used to decode video sync signals that are encoded on the received common-mode voltages, to receive digital signals, or as general-purpose comparators. The AD8145 can be used in conjunction with the AD8133 or AD8134 triple differential drivers to provide a complete low cost solution for RGB over Category 5 UTP cable applications, including KVM.The excellent common-mode rejection (69 dB @ 10 MHz) of the AD8145 allows for the use of low cost, unshielded twisted pair cables in noisy environments.The AD8145 is available in a 5 mm × 5 mm, 32-lead LFCSP and is rated to work over the extended industrial temperature range of -40°C to +105°C.
