Overview
The TMP01ES-REEL, produced by Analog Devices Inc., is a low-power, programmable temperature controller and sensor. This device generates a voltage output proportional to absolute temperature and provides control signals from one of two outputs when the temperature exceeds or falls below user-set thresholds. The TMP01 integrates a band gap voltage reference with a pair of matched comparators, ensuring precise temperature measurement and control. It is designed for high accuracy and reliability, making it suitable for various industrial and electronic applications.
