1 TECNICAL DATA Low Power Low Offset oltage Dual Comparators IL2903 The IL2903 consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 m 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 CO; MOS clock timers; multivibrators and high voltage digital logic gates.

These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Functional operation should be restricted to the Recommended Operating Conditions. Notes: 1. Split Power Supplies. 2. IN <-0.3. This input current will only exist when voltage at any of the input leads is driven negative. RECOMMENDED OPERATIN CONDITIONS Symbol Parameter Min Max Unit CC DC Supply oltage ±2.5 or 5.0 ±15 or 30 T A Operating Temperature, All Package Types C This device contains protection circuitry to guard against damage due to high static voltages or electric fields. owever, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, IN and OUT should be constrained to the range ND ( IN or OUT ) CC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either ND or CC ). Unused outputs must be left open.
