Part Number : TMP121-EP
Function : 1.5°C ACCURATE DIGITAL TEMPERATURE SENSOR
Package : SOT23-6 type
Maker : Burr-Brown , Texas Instruments
Pinouts : 
Description :
The TMP121, TMP121-EP 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 2.7 V to 5.5 V 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.
