you are confused about the noise.
output noise can be divided into two parts: input noise and system itself have some kind of noise.
differential input can attenuate common mode input noise,it says attenuate input noise.
so, both differential output and single ended output have noise, because of the system itself, however, input noise is attenuated in both cases. |
