Hi,
I use I use this type of shutter:
Voltage to Open is 24VDC, It draws approximately 1.2A .
I use same 24VDC to feed my circuits.When I trigger the shutter,spike occurs on my ADC signal.
I know that using same DC line causes this problem ,but what kind of filter can I use?
Can I figure it out using any filter?

When you have a noise problem- you need to consider:

a) Reduce the generation of noise- post the shutter coil driver circuit.
b) Reduce the sensitivity to noise- shield / filter things.

Do both for maximum results.

Hello,
Here is the shutter drive circuit:
D15 is Schottky diode.
