I would like to know how to use current sense amp in PWM motor drive system.
For example, AD8418 has a peak output by input common-mode step response.
AD8418A,AD8417, AD8210 .... also.
(see AD8418 datasheet Fig.18)
These noise are tough to erase by LPF.
I don't know how to erase these noise.
One idea is to use the differential signal from 2 phase current sense amp outputs.
I don't know if it is good or not. and it is hard to use.
Could I see the recommended circuit?
