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. The device is in the “on” state when the control pin
is pulled to a logic high level.
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 TK11032 has a compensation pin for a 0.1 µF capacitor
that ensures stability over the IC's operating temperature
range.
The TK11032 is available in a miniature SOT-25 surface
mount package.
