1 Introduction

Texas Instruments provides a range of different digital temperature sensors compatible with two-wire, SMBus, and I2C interfaces. These temperature sensors are included under the TI 75 family of sensors. This application note guides customers in selecting the appropriate sensor within the 75-family series of TI Temperature sensors and helps them optimize newer features offered in devices such as TMP1075, TMP110, and TMP112-Q1.

This document provides simplified comparison tables for customers to consider the main differences when replacing components. These specs were carefully chosen to provide the best side-by-side comparison. This document provides a high overview comparison but does not reveal all specs. Further investigation of the data sheets is necessary before making a switch to one of these devices.

To provide additional clarity in hardware and software variations, this article discusses Linux driver compatibility, conversion time, resolution compatibility, and data encoding compatibility.
