Hi,

I have some question about ADuM3150 datasheet as below.

 

1)  not matching 20 years and 50 years

page 13 said that "20 year lifetime at 0.1% failure rate"

but page 20 on Table 16 said "The value is compared to the limits for working voltage in Table 16 for expected lifetime,
less than a 60 Hz sine wave, and it is well within the limit for a 50 year service life. "


Which one is correct?


2) correctness about page 17, 1st sentence

A bypass capacitor from VDD1 to GND1 to local ground is required.

Is "--to GND1 to local ground" correct?


3) wrong arrow direction?

Page 17, Figure 11,

At master side of MISO arrow direction seems wrong direction.


4) wrong number?

page 20, left side 1st sentence said

VAC RMS = 24 V rms seems wrong. It should be 240Vrms.


5) What mean of this sentence?

Page 20, 4 line said;

The value is compared to the limits for working voltage in Table 16 for expected lifetime,
less than a 60 Hz sine wave, and it is well within the limit for a 50 year service life.


I could not get this sentence meaning.

What relationship with " less than a 60 Hz sine wave " ?


Thank you for your help in advance.

Best regards,

Sofy
