AMC1305xxEVM User's Guide

This user's guide describes the characteristics, operation, and use of the AMC1305EVM populated with
either the AMC1305L25, AMC1305M05 or AMC1305M25. See

Table 1

for additional details about the

analog input range and bandwidth for each component in the AMC1305 family. The AMC1305EVM is
designed for prototyping and evaluation. A complete circuit description, schematic diagram, and bill of
materials are included.

Throughout this document, the abbreviation

EVM

and the term

evaluation module

are synonymous with

the AMC1305EVM.

The following related documents are available through the Texas Instruments web site at
