      Is it possible to use ADuM5402CRWZ for I2C communication. What will happen if I short VIB with VOC and VOB with VIC ??

      Kabasakal-san: In answer to your question, by the ADUM5402A I mean the ADUM5402ARWZ which has 100ns max prop delay. By the ADUM5402C I mean the ADUM5402CRWZ which has a max of 60ns prop delay. I await your answer to my request. Regards, Brian

      Hi, Firstly, thanks for your answer. My clock frequency is 67KHz. It is not even close to the 2.5MHz. The design is working for more than 10 years but in some boards I got this problem. What do you mean by ADUM5402A or ADUM5402C? Is it ADUM5402ARWZ and ADUM5402CRWZ …

      Hi Brian, Thank you for the quick response. On two CCAs that have shown this issue, I see part markings of: ADUM5402 CRWZ 1403 2786459,1 I imagine that 1403 is the date code. So it looks like these parts are after the revision? Thanks, Scott

      We had to make some component substitutions and PCB layout changes due to the supply chain issues, and due to lack of availability, substituted the ADUM5402ARWZ we have been using successfully for years with ADUM6402CRWZ. We did have to make small adjustment to the Viso pin PCB layout connections, but …

      We have an application where we are using the ADUM5401CRWZ along with an A/D. Our front-end requires full +5V out of the ADUM5401CRWZ in order to achieve the desired input range and achieve full scale with the A/D. Wondering if it is possible to have the ADUM5401CRWZ …

      Hi, We are currently using the ADuM2402 with an approximately 27MHz SPI clock rate. We added LC filters to the output of the ADuM as an EMC mitigation (in addition to stitching capacitance and edge guards on the PCB). We are noticing some data corruption when the ambient temperature around …

      After further checking, we have identified some soldering process issues on a DFN-style module that is either causing shorts & loading down some of the Vdd and a 3.3V net connections, or another soldering issue under a BGA part causing opens and resulting in high impedance connections on another …

      There are no other significant differences between the ADuM5402 and ADuM6402 other than the VDDL pin that would produce the operation as described, it does appear to be sensitive to some other system related line or load sequencing event. Please feel free to reach out to me directly for additional …
