TINY SOT23-6 PACKAGE
DESCRIPTION
The TMP121 and TMP123 are SPI-compatible tempera-
ture sensors available in the tiny SOT23-6 package.
Requiring no external components, the TMP121 and
TMP123 are capable of measuring temperatures within
2°C of accuracy over a temperature range of −40°C to
+125°C. Low supply current, and a supply range from 2.7V
to 5.5V, make the TMP121 and TMP123 excellent
candidates for low-power applications.
The TMP121 and TMP123 are ideal for extended thermal
measurement in a variety of communication, computer,
consumer, environmental, industrial, and instrumentation
applications.
