ADUM4120ARIZ

ADuM4120 is an Isolated, single-channel driver that employ Analog Devices, Inc., iCoupler® technology to provide precision isolation. Combining high speed CMOS and monolithic transformer technology, this isolation components provide outstanding performance characteristics, such as the combination of pulse transformers and gate drivers. The ADuM4120 operates with input supplies ranging from 2.5V to 6.5V providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies, it offers the benefit of true, galvanic isolation between the input and the output. The glitch filter helps reduce the chance of noise on the input pin triggering an output. Typical application includes switching power supplies, isolated gate bipolar transistors (IGBT)/MOSFET gate drives and industrial inverters.
