Analog Devices Isolated Precision Gate Drivers: What is the difference between the ADuM4120 and ADuM4120-1?

Power supply monitoring, control and protection

• The ADuM4120 has a 20 nS glitch filter at the input stage.
• The ADuM4120-1 does not have a glitch filter at the input stage.
 
The disadvantage of the ADuM4120-1 is that it does not have a filter, so it is vulnerable to noise environments, but the advantage is that the propagation delay from input to output is 20 ns faster.
