IK Semicon IL2903N Low power low offset voltage dual comparator Datasheet

TECHNI CAL DATA
Low Power Low Offset Voltage Dual
Comparators
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.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
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. VIN<-0.3V. This input current will only exist when voltage at any of the input leads is driven negative.

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, VIN and VOUT should be
constrained to the range GND≤(VIN or VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
