ANALOG DEVICES Evaluation Board AD1555/AD1556 24-Bit handbook
The document provides a comprehensive guide for the EVAL-AD1555/56EB evaluation board, which is designed to demonstrate the performance and operation of the AD1555 and AD1556 24-bit ADC chip-set. Key features include on-board reference voltage, oscillator, control logic, and buffers, along with easy interface capabilities for PC printer ports or stand-alone operation via a 50-pin connector.
The manual details the board's power supply blocks, grounding planes (DGND, LGND, AGND), and analog input configurations. It also explains how to install and operate the accompanying Windows 95 software, which allows users to perform time domain response analysis, spectral response measurements, and histogram charts, as well as compute dynamic range, equivalent input noise, Total Harmonic Distortion (THD), and DC offset.
