Hello

I am looking for the isolated current sensor amplifier with single ended output to measure 0-200mA in one of my circuit. sensing will be at high side. or any hall effect sensor those are suitable for low current sensing.

AC or DC?

 

Hello

its a DC current.

 

 

The proper way to do this - if you want to measure isolated DC current is to use a Hall Effect transducer.
This packaged device described in the link below gives out a DC voltage in proportion to the primary DC current.
The input range for this device is +/- 1.7A but if it can be made more sensitive by winding a number of turns through the core as the primary. Example: 8 turns at 200mA will equal 1.6A.
