DESCRIPTION

The TMP125 is an SPI-compatible temperature sensor

available in the tiny SOT23-6 package. Requiring no

external components, the TMP125 is capable of

measuring temperatures within 2°C of accuracy over a

temperature range of −25°C to +85°C and 2.5°C of

accuracy over −40°C to +125°C. Low supply current, and

a supply range from 2.7V to 5.5V, make the TMP125 an

excellent candidate for low-power applications.

The TMP125 is ideal for extended thermal measurement

in a variety of communication, computer, consumer,

environmental, industrial, and instrumentation

applications.
