The AD8133 is a major advancement beyond using discrete op amps for driving differential RGB signals over twisted pair cable. The AD8133 is a triple, low cost differential or single-ended input to differential output driver, and each amplifier has a fixed gain of 2 to compensate for the attenuation of line ter-mination resistors. The AD8133 is specifically designed for RGB signals but can be used for any type of analog signals or high speed data transmission. The AD8133 is capable of driving either Cate-gory 5 unshielded twisted pair (UTP) cable or differential printed circuit board transmission lines with minimal signal degradation.
The outputs of the AD8133 can be set to a low voltage state to be used with series diodes for line isolation, allowing easy dif-ferential multiplexing over the same twisted pair cable. The AD8133 driver can be used in conjunction with the AD8129 and AD8130 differential receivers.
