DESCRIPTION
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
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.
