DESCRIPTION
The TMP105 is a two-wire, serial output temperature
sensor available in a WCSP package. Requiring no
external components, the TMP105 is capable of
reading temperatures with a resolution of 0.0625°C.
The TMP105 features a Two-Wire interface that is
SMBus-compatible, with the TMP105 allowing up to
two devices on one bus. The TMP105 features an
SMBus Alert function.
The TMP105 is ideal for extended temperature
measurement in a variety of communication,
computer, consumer, environmental, industrial, and
instrumentation applications.
The TMP105 is specified for operation over a
temperature range of 40°C to +125°C.

This integrated circuit can be damaged by ESD. Texas Instruments 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.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.
(2) Input voltage rating applies to all TMP105 input voltages.
(3) HBM testing has been tested to TI specifications JEDEC JESD22-A114C.01.
(4) CDM testing has been tested to TI specifications JEDEC EIA/JESD22-A115A.
