AD8133ACPZ-REEL7

GENERAL DESCRIPTION

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 singleended input to differential output driver, and each amplifier has a fixed gain of 2 to compensate for the attenuation of line termination 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 Category 5 unshielded twisted pair (UTP) cable or differential printed circuit board transmission lines with minimal signal degradation.
