Could you please provide the UL 1577 safety report for ADUM120N?
For the second part of my answer, I did mean A4953, sorry for the confusion.
The output voltages would be the supply voltage for the ADuM3220, but since this would be an output, a simple voltage divider would suffice to get the voltages in range for…
You could try ADuM120N or ADuM121N. The power up glitch is resolved in design level.
For ADuM128x, we did not see this glitch on bench evaluation, if you really want it, we can double confirm with designer. please send mail to me via chris.qin…
IDD1 = IDD1(Q) + (2.8mA * D_A + 0.01mA/Mbps * F_A) + (2.8mA * D_B + 0.01mA/Mbps * F_B)
IDD2 = IDD2(Q) + (0.02mA/Mbps * F_A)+ (0.02mA/Mbps * F_B)
IDD1 = IDD1(Q) + (2.8mA * D_B + 0.01mA/Mbps * F_B) +(0.02mA/Mbps * F_A…
Welcome to the world of digital isolation. I think you'll like it here!
Its no problem having 3.3V CMOS inputs and driving 5.0V TTL loads. The layout is simple. You just pick your favorite 2-channel device and two good 0.1uF bypass caps…
