The TK11070 is a temperature sensor IC with a linear negative slope output of -8 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. The device is in the "on" state when the control pin is pulled to a logic high level. In the "off" state,the standby current is 1  A maximum.

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 TK11070 has a compensation pin for a 0.1  F capacitor that ensures stability over the IC's operating temperature range.

The TK11070 is available in a miniature SOT-23-5 surface mount package.
