artem said:So i get you wrong when you said scope in ac coupling measure.)
What is the sampling rate of your ADC ?
What do you see from scope when probing dspic ADC input directly?
Is it same signal (same form) as on sensor output ?
Do you use analog low pass filter before ADC and what it is order and cut frequency ?
Could you post your schematics with exact component values ?

seyyah said:I'm confused at this coupling issue. Whay scope shows the signal so differently, i didn't understand. I was expecting only a 2.5V shift in dc coupling setting.

Or do you need to measure winding voltage transient during PWM switch deadtime ?
