AD8134 is a three-way differential driver from Analog Devices, it uses Sync-On-Common-Mode technology, it has 225 MHz, -3 dB large signal bandwidth and 450 MHz, -3 dB small signal bandwidth. AD8134 can easily drive 1.4 V p-p video signal into doubly terminated 100 Ω UTP cable.
The AD8134 is a triple high‑speed differential driver with a fixed internal gain of 2, designed for RGB video and other high‑speed analog signals. It features on‑chip sync‑on‑common‑mode circuitry, output pull‑down for line isolation, and high isolation between amplifiers.
The document includes detailed specifications such as bandwidth, slew rate, supply voltage range, and thermal characteristics, as well as pin descriptions, typical performance graphs, ordering information, and mechanical dimensions for the 24‑lead LFCSP package.
