1. Overview

Evaluation boards for ADCs are specialized hardware platforms designed to test and validate analog-to-digital converter performance in controlled environments. These boards provide developers with a standardized interface to measure critical parameters such as resolution, sampling rate, and signal fidelity. In modern electronics, ADC evaluation boards play a vital role in accelerating the development of systems that require precise analog signal digitization, including communication infrastructure, medical imaging equipment, and industrial automation systems.
