SGLS315 – SEPTEMBER 2005
1.5°C ACCURATE DIGITAL TEMPERATURE SENSOR WITH SPI™ INTERFACE
FEATURES
• Controlled Baseline
– One Assembly/Test Site, One Fabrication
Site
• Extended Temperature Performance of -40°C
to 125°C
• Enhanced Diminishing Manufacturing
Sources (DMS) Support
• Enhanced Product-Change Notification
• Qualification Pedigree (1)
• Digital Output: SPI-Compatible Interface
• Resolution: 12-Bit + Sign, 0.0625°C
(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.
• Accuracy: ±1.5°C from –25°C to 85°C (max)
• Low Quiescent Current: 50 µA (max)
• Wide Supply Range: 2.7 V to 5.5 V
• Tiny SOT23-6 Package
• Operation to 150°C
APPLICATIONS
• Power-Supply Temperature Monitoring
• Computer Peripheral Thermal Protection
• Notebook Computers
• Battery Management
• Environmental Monitoring
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 2.7 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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.
