DESCRIPTION
TK11044
The TK11044 is a temperature sensor IC with a linear
output of 10 mV/°C over the range of -25 to + 105 °C. 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
climatecontrol,refrigerators,andindustrialprocesscontrols.
