DAC82002EVM User's Guide

ABSTRACT

This user’s guide describes the characteristics, operation, and use of the DAC82002 evaluation module (EVM). 
This EVM is designed to evaluate the performance of the 

DAC82002

 commercial, unbuffered voltage output 

DAC in a variety of configurations. Throughout this document, the terms evaluation board, evaluation module, 
and EVM are synonymous with the DAC82002EVM. This document includes a schematic, printed-circuit board 
(PCB) layouts, and a complete bill of materials.
