DESCRIPTION
The TK11070 is a temperature sensor IC with a linear
negative slope output of -8 mV/擄C over the range of -30
to + 105
擄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 鈥渙n鈥?state when the
control pin is pulled to a logic high level. In the 鈥漮ff鈥?state,
the standby current is 1
碌A(chǔ)
maximum.
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 TK11070 has a compensation pin for a 0.1
碌F
capacitor
that ensures stability over the IC's operating temperature
range.
The TK11070 is available in a miniature SOT-23-5 surface
mount package.
