Frequently Asked Questions

What is the supply voltage range of the LM2903N?

The LM2903N operates from a single supply of 2V to 36V or a split supply of ±1V to ±18V, making it highly versatile for both low-voltage and industrial applications requiring wide operating ranges.

What package does the LM2903N come in?

The LM2903N is available in an 8-pin DIP (PDIP) through-hole package, which is ideal for prototyping and breadboard development. It contains two independent voltage comparators in this compact, easy-to-solder package.

Can the LM2903N output interface directly with TTL and CMOS logic?

Yes, the LM2903N features open-collector outputs capable of sinking up to 50mA, allowing direct interfacing with TTL, CMOS, and MOS logic families. A pull-up resistor to the desired logic supply voltage is required to complete the output stage.

What are typical applications for the LM2903N?

The LM2903N is commonly used in window comparators, zero-crossing detectors, voltage level shifters, battery voltage monitors, motor control feedback circuits, and power supply supervisory functions in both industrial and consumer electronic designs.
