Learn about Avago's solution for sensing motor current and transmit signals from high voltage motor phases/rails to the control circuit for your next design. Our Isolation amplifiers, working in conjunction with shunt resistors, provide accurate current measurements in power converter applications in the presence of high switching noise. These devices include a built-in A/D converter and robust optical coupling technology to achieve high gain accuracy and common mode noise rejection.

Typical applications include motor phase and rail current sensing, inverter current sensing, general purpose current sensing, and voltage sensing. Compared to traditional Hall Effect transducers or current transformers, the iso-amps provide smaller size, superior measurement accuracy, and lower cost solution.
