Current loops are useful for accurately communicating analog signals over long distances. Unlike voltage, current does not vary due to line resistance or capacitance—both which change with cable length. Current loops provide a high level of noise immunity. As a result, they are widely used in electrically noisy environments.

Maxim provides a wide range of products designed for implementing and protecting 4-20mA communication links.
