SLAU173A – December 2005 – Revised November 2009 DAC8580/81 Evaluation Module This user guide describes the characteristics, operation, and the use of the DAC8580/81 Evaluation Module. It covers all pertinent areas involved to properly use this EVM board along with the devices that it supports. -
Page 2: Evm Overview
DAC8580/81EVM is used throughout this document. Features This EVM features the DAC8580/81 digital-to-analog converter (DAC). It provides a quick and easy way to evaluate the functionality and performance of the high-resolution, serial input DAC. The EVM provides the serial interface header to easily attach to any host microprocessor or TI DSP-based system for communication. -
