The document provides information about BDTI C and ADI companies.
The AD7820 is a high‑speed 8‑bit analog‑to‑digital converter that uses a half‑flash conversion technique to achieve conversion times around 1.36 µs. It features a built‑in track‑and‑hold function, no missed codes, and operates from a single +5 V supply, making it easy to interface directly with microprocessors.
The document provides detailed specifications, timing characteristics, absolute maximum ratings, pin configurations, mechanical dimensions, and application information such as reference configurations and input circuitry. It also includes ordering information for the various DIP, SOIC and surface‑mount packages.
