TMP1075EVM User's Guide

The industry standard LM75/TMP75 is now available with high accuracy and a wider temperature range.
The TMP1075 is a drop-in replacement for the most prevalent digital temperature sensors with enhanced
features. The TMP1075 provides up to ±0.5°C typical accuracy over the

25°C to +85°C range, and ±1°C

typical accuracy over the

55°C to +125°C range with 12-bit resolution, giving a temperature resolution of

0.0625°C. The Texas Instruments TMP1075EVM (Evaluation Module) provides the user a simple way to
get started with TMP1075. The module and GUI are designed to provide the user a quick setup to
evaluate the system and register map. The EVM features a perforation that allows the temperature sensor
to be placed away from the MSP430 for remote temperature measurements and a header to connect
multiple TMP1075’s to the controller. This document provides detailed information about the hardware
design and software installation.
