Overview
The TMP108AIYFFR is a digital-output temperature sensor produced by Texas Instruments. It is designed to provide optimized temperature control with advanced features such as dynamically-programmable limit windows and under- and overtemperature alert functions. This sensor is particularly useful in applications where precise temperature monitoring is crucial without the need for frequent readings by the controller or application processor. The TMP108AIYFFR operates over a wide temperature range of –40°C to +125°C and is compatible with SMBus and two-wire interfaces, allowing up to four devices on one bus with the SMBus alert function.
