Overview
The AD8133ACPZ-REEL7, produced by Analog Devices Inc., is a triple differential or single-ended input to differential output driver. This component is designed to provide a cost-effective and high-performance solution for driving differential signals, particularly in applications requiring high-speed signal transmission over twisted pair or coaxial cables.
Manufactured using Analog Devices’ next-generation XFCB bipolar process, the AD8133 offers a large signal bandwidth of 225 MHz and a slew rate of 1600 V/µs. It is specifically tailored for applications such as KVM (keyboard-video-mouse) networking, UTP (unshielded twisted pair) driving, and differential signal multiplexing.
