The TMP122 is an SPI-compatible temperature sensor available in an SOT23-6 package. Requiring only a pull-up resistor for complete function, the TMP122 temperature sensor is capable of measuring temperatures within 2°C of accuracy over a temperature range of ?55°C to 125°C, with operation up to 150°C. Programmable resolution, programmable set points and shut down function provide versatility for any application. Low supply current and a supply range from 2.7 V to 5.5 V make the TMP122 an excellent candidate for low-power applications.
The TMP122 is ideal for extended thermal measurement in a variety of communication, computer, consumer, environmental, idustrial, and instrumentation applications.
