AC current measurement using shunt resistor

resistor chosen is 100 mohm. which gives me max 8*1.414*10=1.13 Volt that i will use to feed an opamp to further amplify it to around max 3V with proper gain setting. and that will go to my micro controller ADC

Shunt Current measurement noise

PB5-AI will to ADC which has max 1 Volt limit. … waveform, and when i reduce time scale of same waveform i observe spike on waveform(see picture), I tried to add 0.1uf cap across R30, but not helped. any suggestion I doubt with this much noise my ADC
