DESCRIPTION
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, industrial, and
instrumentation applications.
