Are op amp and voltage current converter same
XTR110 is a specialty IC designed for use in industrial environments, where 4 to 20mA currents are a common way to communicate analog values between industrial modules. It can be configured for a variety of output currents, including 0 to 10mA. Internally, it's implemented much the same way as an opamp solution, as shown by its schematic diagram in the datasheet.

Whether you use this IC, one like it, or implement it yourself using opamps, depends on your precision requirements, your budget, and other design constraints.
