DAC80502 Evaluation Module

This user’s guide describes the characteristics, operation, and use of the DAC80502EVM evaluation
module (EVM). This EVM is designed to evaluate the performance of the

DAC80502

buffered voltage

output DAC in a variety of configurations. Throughout this document, the terms evaluation board,
evaluation module, and EVM are synonymous with the DAC80502EVM. This document includes a
schematic, reference printed-circuit board (PCB) layouts, and a complete bill of materials.
