Overview
The AD8133ACPZ-REEL, manufactured by Analog Devices Inc., is a triple, low-cost differential or single-ended input to differential output driver. This component is designed to drive differential signals over twisted pair cables or differential printed circuit board transmission lines with minimal signal degradation. Each amplifier in the AD8133 has a fixed gain of 2, which compensates for the attenuation caused by line termination resistors. It is particularly suited for driving RGB signals but can be used for any type of analog signals or high-speed data transmission.
