DESCRIPTION
The TK11034 is a temperature sensor IC with a linear
output of 10 mV/擄C over the range of -30 to + 105
擄C.
Its
wide operating voltage range of 2.4 to 8.0 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 鈥渙n鈥?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.
Note: Both GND pins must connect to GND

The TK11034 has a compensation pin for a 0.1
碌F
capacitor
that ensures stability over the IC's operating temperature
range.
The TK11034 is available in a miniature SOT-23L surface
mount package.
