ADuM120x is a dual-channel digital isolator. The isolation device integrates high-speed CMOS and single-chip transformer technology, and has excellent performance characteristics superior to alternative optocoupler devices. DUM1201 is based on ADI's patented iCoupler digital isolator using planar magnetic field patented isolation technology. Because it is based on iCoupler technology, ADUM1201 has many advantages over opto-isolators: the speed is higher and the maximum rate can reach 125Mbps.
