The TMP125 is an SPI-compatible temperature sensor available in the tiny SOT23-6 package. Requiring no external components, the TMP125 is capable of measuring temperatures within 2°C of accuracy over a temperature range of –25°C to +85°C and 2.5°C of accuracy over –40°C to +125°C. Low supply current, and a supply range from 2.7V to 5.5V, make the TMP125 an excellent candidate for low-power applications.

The TMP125 is ideal for extended thermal measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.
