Hi My friends.
I have a problem with measure ac current , I have a 100 to 200 ma AC @ 1KHZ current that should be measure via ADC , first step i use acs715 but low current cause very low voltage plus noise on acs712 output so i can not use acs712 for this range of current .
anyway i should use very precise shunt but important issue i can not find precise shunt in this region i can not find that , did you have any idea can measure that range of ac current without shunt
Thanks ,
output of acs712-5
my shunt ( 10 % Error)
Current across the shunt
