GENERAL D ESCRIP TIO N

T he ADT 05 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.

T he ADT 05 is a solid state thermostatic switch. Requiring only

one external programming resistor, the ADT 05 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

ADT 05 asserts an open collector output when the ambient

temperature exceeds the user-programmed setpoint temperature.

The ADT05 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.
