1. Overview

Linear video processing ICs are analog integrated circuits designed to process continuous video signals without digitization. They perform functions like amplification, filtering, and signal conditioning while maintaining signal integrity. These components are critical in applications requiring real-time video processing with minimal latency, forming the backbone of analog video systems in broadcast, surveillance, and industrial equipment.
