Low Power Digital Temperature Sensor
With SMBus™/Two-Wire Serial Interface in SOT563
23
TINY SOT563 PACKAGE
The TMP102 is a two-wire, serial output temperature
sensor available in a tiny SOT563 package. Requiring
ACCURACY: 0.5 ° C ( 25 ° C to +85 ° C)
no external components, the TMP102 is capable of
LOW QUIESCENT CURRENT:
reading temperatures to a resolution of 0.0625 ° C.
10 µ A Active (max)
The TMP102 features SMBus and two-wire interface
1 µ A Shutdown (max)
compatibility, and allows up to four devices on one
SUPPLY RANGE: 1.4V to 3.6V
bus. It also features an SMB alert function.
RESOLUTION: 12 Bits
The TMP102 is ideal for extended temperature
DIGITAL OUTPUT: Two-Wire Serial Interface
measurement in a variety of communication,
computer, consumer, environmental, industrial, and
instrumentation applications. The device is specified
PORTABLE AND BATTERY-POWERED
for operation over a temperature range of 40 ° C to

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.
