TK11041

TEMPERATURE SENSOR IC

DESCRIPTION

The TK11041 is a temperature sensor IC with a linear

output of 10 mV/

°C over the range of -30 to + 105 °C. Its

wide operating voltage range of 4.5 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.

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 TK11041 has a compensation pin for a 0.1

µF capacitor

that ensures stability over the IC's operating temperature

range.

The TK11041 is available in a miniature SOT-25 surface

mount package.
