TMP123

TMP121 TMP123 SBOS273C − JUNE 2003 − REVISED FEBRUARY 2005 1.5°C Accurate Digital Temperature Sensor with SPI Interface D DIGITAL OUTPUT: SPI-Compatible Interface D RESOLUTION: 12-Bit + Sign, 0.0625°C www.DataSheet4U.com D ACCURACY: D D D D OPERATION TO 150°C ±1.5°C from −25°C to +85°C (max) LOW QUIESCENT CURRENT: 50µA (max) WIDE SUPPLY RANGE: 2.7V to 5.5V TINY SOT23-6 PACKAGE FEATURES 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.
