TECHNICAL DATA
Low Power Low Offset Voltage Dual Comparators
IL2903
The IL2903 consists of two independent precision voltage
comparators with an offset voltage specification as low as 2.0
mV max for two comparators which were designed
specifically to operate from a single power supply over a
wide range of voltages.
Application areas include limit comparators, simple analog
to digital converters; pulse, squarewave and time delay
generators; wide range VCO; MOS clock timers;
multivibrators and high voltage digital logic gates.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range GND
(V

or

)

.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused outputs must
be left open.
