Overview
The TMP102AIDRLR is a low-power digital temperature sensor produced by Texas Instruments. It is designed to replace NTC/PTC thermistors in applications where high accuracy is required. The device offers an accuracy of ±0.5°C without needing calibration or external component signal conditioning. It features a highly linear temperature sensor that does not require complex calculations or lookup tables to derive the temperature. The TMP102 is packaged in a compact SOT563 package, which is 68% smaller than the SOT-23 package, making it ideal for space-constrained designs.
