Its wide operating voltage range of 2.4 to 8.0 volts makes it suitable for a number of applications requiring accurate temperature control, such as electronic thermostats for climate control, refrigerators, and industrial process controls. A typical application is to make a digital representation of temperature with an A/D converter, or to make a thermal detector with a comparator. The TK11044 has a compensation pin for a 0.1 µF capacitor that insures stability over the IC's operating temperature range. The TK11044 is available in a miniature SOT 23L-6 surface mount package.
