    Hi friends, Is there any provision for IC which has multiple current to voltage convertors about 6 in the conversion range of 4-20mA into 0-3.3V(or 0-3V).

    An op amp and a resistor will do this quite nicely, and you can get quad op amps.

    Vout = R X Current

    If you need an inline current measurement it gets slightly more complicated, think shunt resistor with differential amp (another op amp circuit).
