Good differential amps are differential in & differential output. TI calls these Fully differential amps C |

As always a giant knowledge you all share!! Thanks, really thanks!! :-) What would you recommend now then, a cap from lead to case/ground, an inductor, ferrite ring or something else, to remove 30khz and up? |
| C:
A filter is not magic. When you add something, most times you effect all signals. When you do a 30k low pass filter that is just effecting the higher more then below. So first question is how do you know you have a problem? You can not hear 30k so how do you know it is there and how much are you measuring. I would expect the output of a CD drive to be good. C |
