#83548 - My car makes pling pling...
Responding to: ???'s previous message
My car makes pling pling. Can you help me to fix it?

Jin,

if you do not tell us more, what your circuit is doing, it's impossible to find any suited cure for your problem. There are dozens of reasons, why the one OPamp can give more noise than the other.
One way to reduce noise is to provide some bandwidth limiting. This can filter out noise in a frequency region, where no signal occurs. But again, we need to have much much more details!
