LINEAR TECHNOLOGY LTC2996 high accuracy temperature sensor for 2.25V to 5.5V systems measure a remote diode’s temperature with ±1C accuracy and its own die temperature with ±2C accuracy, while rejecting errors due to noise and series resistance. Device provides a voltage-proportional-to-absolute-temperature (VPTAT) output, as well as individual undertemperature and overtemperature alert outputs, defined by user-adjustable thresholds. No code is required to configure the device. With a 200µA quiescent current, the LTC2996 simply provides a precise, space-saving, micropower temperature monitoring solution.
