TMP125 SBOS323 − DECEMBER 2004 2°C Accurate Digital Temperature Sensor with SPI Interface D DIGITAL OUTPUT: SPI-Compatible Interface D RESOLUTION: 10-Bit, 0.25°C D ACCURACY: www.DataSheet4U.com ±2.0°C (max) from −25°C to +85°C ±2.5°C (max) from −40°C to +125°C FEATURES 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.

Exposure to absolute maximum conditions for extended periods www.DataSheet4U.com may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current limited to 10mA or less. (3) Short-circuit to ground. This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
