Evaluation Boards - Digital to Analog Converters (DACs)

1. Overview

DAC Evaluation Boards are specialized hardware platforms designed to test and validate Digital-to-Analog Converter (DAC) performance in various applications. These boards convert digital signals to analog waveforms with precise control over parameters like resolution, sampling rate, and linearity. They play a critical role in developing systems requiring accurate signal generation, such as communication infrastructure, medical imaging, and industrial control systems.
