Can these devices isolate (filters out) high frequency noise.
The ADuM3440 doesn’t explicitly filter high frequency noise, but it does block current flow from one side to the other so noise is isolated. The typical capacitance across the…
1. The "units" means different channels of different ADuM3440( eg: between ch1 of one ADuM3440 and ch2 of the other)
2. Yes, tPSKCD is the propagation delay between any two channels of a given ADuM3440.
3. tPSK and tPSKCD are tested…
The enable fucntion of digital isolators is designed at the output side, and you could think that the enable propagation delay of ADuM141E is similar to ADuM3440's.
Will tPSK and tPSKCD change sfter ADuM3440 is powered up, or they are fixed each time we use?
And what tPSK will be, if CL = 5 pF?
2] The ADuM3440 is to protect this board from the drivers and them from each other..
I only use 3/4 of the io's on each ADuM
it is only outgoing commands.
