DESCRIPTION

The TMP121 and TMP123 are SPI-compatible temperature

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.
