DESCRIPTION
The TMP122 and TMP124 are SPI-compatible temperature
sensors available in SOT23-6 and SO-8 packages. Requir-
ing 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 low-
power applications.
The TMP122 and TMP124 are ideal for extended thermal
measurement in a variety of communication, computer, con-
sumer, environmental, industrial, and instrumentation appli-
cations.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
