The LM75B and TMP1075 are now industry-standard benchmarks in digital temperature sensors with an I2C® interface. Originating from the LM75, first introduced by National Semiconductor in the 1990s, these devices are now key components of TI’s digital temperature sensor portfolio. Their long-lived popularity lies in their flexibility, widespread availability, and cost efficiency.
Before integrating these sensors into your design, it is crucial to understand their nuances and the subtle yet important differences. This is particularly vital in designs requiring compatible pin-to-pin alternate parts. The information in this application note is aimed to help you make informed choices, simplifying the selection process and promoting first-time success in your LM75-based designs.
