Isolated A/D Converters

As the world’s leading supplier of data converters, Analog Devices is constantly introducing new A/D converters (ADCs) that drive system architectures. In the motor control arena, ADI’s converters solve the challenges associated with current and voltage monitoring, optical encoder feedback, and resolver-to-digital conversion. The introduction of the isolated ADC with its 3.75 kV standoff voltage is one example of ADI’s breakthroughs in performance and integration to ease the burden of design.
