Re: doubt

If you want anybody to help you, you must specify your problem more precisely...
Your description can be clear just for clairvoyants.

Re: doubt

It sounds like you need bypassing. For your power supply pins, tie 10uF capacitor at each of your power pins to ground. For your op-amps and device with power pins, tie 4.7uF and 0.1uF capacitors very close to the pins.

In the case you have really bad spikes coming from your supply, put 2 clamping diodes at the power supply pins. This would clamp your supplies from really nasty spike.

Well, the first clairvoyant... ;-)
(don't take it bad, I'm joking)
