Beginner Question on Comparator.
« on: November 10, 2015, 11:52:49 pm »
I found an IC in a power supply, the Texas Instruments Lm393, which I read is called a low power dual voltage comparator. What does a low power dual voltage comparator do?

It compares two voltages and tells you which is higher.

"Dual" means there are two separate comparators in the one chip.
