The TK11042 is a temperature sensor IC with a linear output of 6 mV/°C over the range of -30 to + 105 °C. Its wide operating voltage range of 2.7 to 10.0 V 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 TK11042 has a compensation pin for a 0.1 F capacitor that ensures stability over the IC's operating temperature range.

The TK11042 is available in a miniature SOT-25 surface mount package.
