General Description

The ADuM3220/ADuM32211 are isolated, 4 A dual-channel gate drivers based on the Analog Devices, Inc., iCoupler® technology.

Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers.

The ADuM3220/ADuM3221 provide digital isolation in two independent isolation channels.
