Overview
The AD8110AST, produced by Analog Devices Inc., is a high-speed 16 × 8 buffered video crosspoint switch matrix. This integrated circuit is designed to handle high-speed signal routing with excellent video performance and low power consumption. The AD8110AST is part of the AD8110 series, which includes the AD8111, differing primarily in their gain settings (AD8110: G = +1, AD8111: G = +2). These devices are ideal for applications requiring precise and high-bandwidth signal switching.
