SBOU099A – January 2011 – Revised April 2018

TMP103EVM

This user's guide describes the characteristics, operation, and use of the TMP103EVM evaluation board. It
provides a detailed description of the hardware design. It discusses how to set up and configure the
evaluation module (EVM) software, and reviews the hardware and various aspects of the software
operation. This document also includes information regarding operating procedures and input/output
connections, an electrical schematic, printed-circuit board (PCB) layout drawings, and a parts list for the
TMP103EVM. Throughout this document, the terms

evaluation board

,

evaluation module

, and

EVM

are

synonymous with the TMP103EVM.
