TMP122 TMP124 SBOS272B – JUNE 2003 – REVISED DECEMBER 2003 1.5°C Accurate Programmable Digital Temperature Sensors with SPI™ Interface FEATURES q DIGITAL OUTPUT: SPI-Compatible Interface q PROGRAMMABLE RESOLUTION: 9- to 12-Bits + Sign q ACCURACY: ±1.5°C from –25°C to +85°C (max) ±2.0°C from –40°C to +125°C (max) q LOW QUIESCENT CURRENT: 50µA q WIDE SUPPLY RANGE: 2.7V to 5.5V q TINY SOT23-6 AND SO-8 PACKAGES q OPERATION TO 150°C q PROGRAMMABLE HIGH/LOW SETPOINTS DESCRIPTION The TMP122 and TMP124 are SPI-compatible temperature sensors available in SOT23-6 and SO-8 packages. Requiring only a pull-up resistor for complete function, the TMP122 and TMP124 temperature sensors are capable of measuring temperatures within 2°C of accuracy over a temperature range of –40°C to +125°C, with operation up to 150°C. Programmable resolution, programmable set points and shut down function provide versatility for any application. Low supply current and a supply range from 2.7V to 5.5V make the TMP122 and TMP124 excellent candidates for lowpower applications. The TMP122 and TMP124 are ideal for extended thermal measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.
