Driver for LM75 temperature sensor.
National Semiconductor is now a wholly-owned subsidiary of Texas Instruments. Many temperature sensors are compatible with the original LM75, and many of them offer higher resolution, accuracy and additional features. This driver provides a standard view of the LM75 with fixed dynamic resolution.
All correct at time of writing, but as always, manufacturers love to move things around on their website.
