GENERAL DESCRIPTION  
The AD22105 is designed to operate on a single power supply  
voltage from +2.7 V to +7.0 V facilitating operation in battery  
powered applications as well as in industrial control systems.  
Because of low power dissipation (230 µW @ 3.3 V), self-  
heating errors are minimized and battery life is maximized.  
The AD22105 is a solid state thermostatic switch. Requiring  
only one external programming resistor, the AD22105 can be set  
to switch accurately at any temperature in the wide operating  
range of –40°C to +150°C. Using a novel circuit architecture,  
the AD22105 asserts an open collector output when the ambient  
temperature exceeds the user-programmed setpoint temperature.  
The AD22105 has approximately 4°C of hysteresis which prevents  
rapid thermal on/off cycling.  
An optional internal 200 kΩ pull-up resistor is included to  
facilitate driving light loads such as CMOS inputs.  
Alternatively, a low power LED indicator may be driven directly.
