DESCRIPTION
The TK11032 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.Thedeviceisinthe“on”statewhenthecontrolpin
