I want to know the input and output current ratings and power ratings of ADuM4150BRIZ spi isolator IC for both sides ??
I am using 3.3v supply on both sides.
Can you tell me in primary side and secondary side versa ?
Thanks in Advance
If you refer to the DC Specification section of the datasheet's spec tables, you'll find the VOL and VOH specs at different loads.
Table 5 for 3.3V.
Thank You for your reply.
May i know the output and input current details and total power consumption of IC ?
They mentioned 20microAmperes as Ioutput ? Is it Enough because in Table 13 they mentioned that total power consumption is 2.4w.
Im confused just tell me each side at maximum level how much current will it take to work in full speed ?
Total power required by the isolator is going to depend on the load its driving and the data rate.
If you refer to the Typical Performance Curves sections, there are curves with the per channel idd measurements. There are also the Supply Current specs in Table 5, those limits are given at 1 and 17 MHz.
Just remember to factor in the power required to drive the capacitance of the signal traces themselves. (c*v^2*f) The specification tables and typical performance curves assume no load unless stated otherwise.
Thank You jason
