Hi,

i want to convert 4 to 20mA into 0-3.3 v range.
I know about RCV420. but it needs negative supply.
Anyone knows any ICS, which is converting the current into voltage other than RCV420?

Thanks in Advance

Use a resistor.

R = V/I = 3.3V/20mA = 165 Ohms. Use 180 Ohms.
 

Just google for ' 4mA to 20mA CURRENT LOOP RECEIVER' and you will find few solutions even on first page.
