I'm driving an LC load using ULN2003AN IC. The input pulses are 5V at 25 KHz with 50% duty cycle.
I connected an oscilloscope (VM1) to the coil. I was hoping to see some kickback a voltage levels, but there wasn't any. All I got was an alternating square signal between 0 and 11V.
How do I see the kickback voltage? Should I be changing the frequency/duty cycle or is it the ULN2003 not suitable for this task?
