Hi,
I believe to remember that I was told not to use dual (or quad, etc.) OpAmps, because the two OpAmps within one housing could impact each other quite significantly.
I have checked some TI OpAmp specs, but could not find a parameter, which would characterize how prone the OpAmps within the same housing are for a mutual influence.
Of course, at the end it will be a question about available space on the PCB, how much noise is acceptable, how I define "significant" etc. ... however, I could image some Dual OpAmps are better "shielded" than others. I am wondering: isn't there any "standard" parameter in the specs, which would tell me how strong e.g for a Dual OpAmp the single OpAmps can influence each other?
Thank for all your comments!
