GENERAL DESCRIPTION
The ADuM1420¹ is a quad isolated gate driver that employs
Analog Devices, Inc. iCoupler® technology to provide
independent and isolated high-side and low-side outputs.
In comparison to gate drivers employing high voltage level
translation methodologies, the ADuM1420 offers the benefit of
true, galvanic isolation between the input and each of the four
outputs. Each output can be operated up to ±700 V peak relative to
the input, thereby supporting low-side switching to negative
voltages. The differential voltage between any two outputs can
be as high as 700 V peak.
