DESCRIPTION

The TMP122 and TMP124 are SPI-compatible temperature

sensors available in SOT23-6 and SO-8 packages. Requiring

only a pull-up resistor for complete function, the TMP122

and TMP124 temperature sensors are capable of measuring

temperatures within 2°C of accuracy over a temperature

range of –40°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 2.7V to 5.5V make

the TMP122 and TMP124 excellent candidates for lowpower

applications.

The TMP122 and TMP124 are ideal for extended thermal

measurement in a variety of communication, computer, consumer,

environmental, industrial, and instrumentation applications.
